    LIPEZ, Circuit Judge.          After a thirty-day jury trial,
    appellants William Facteau and Patrick Fabian, former executives
    of the medical device manufacturer Acclarent, Inc., were found
    guilty of multiple misdemeanor violations of the Federal Food,
    Drug, and Cosmetic Act ("FDCA") for commercially distributing an
    adulterated and misbranded medical device. See 
    21 U.S.C. § 331
    (a).
    The charges related to a device developed and sold by Acclarent
    that the government alleged served an intended use different from
    the one for which it had been cleared by the U.S. Food and Drug
    Administration ("FDA").
    On appeal, appellants assert that their prosecutions
    violated their First Amendment rights, relying on an emerging body
    of law protecting commercial speech that promotes off-label uses
    of medical products.     Appellants also argue that their convictions
    violated due process under the Fifth Amendment.            Fabian further
    contends that the jury was wrongly instructed about what evidence
    it could consider, that the evidence was insufficient to support
    his conviction, and that the $500,000 fine the court imposed on
    him is excessive under the Eighth Amendment.
    We reject all of these claims and affirm.
    I.
    The FDCA strictly limits the ways in which manufacturers
    may   market   medical   devices,    including    a   prohibition    on   the
    distribution of "adulterated" or "misbranded" devices.              A device
    - 3 -
    is adulterated or misbranded if its "intended use" -- as determined
    objectively by the seller's statements and conduct -- differs from
    the use(s) for which the FDA has cleared it.
    Facteau,       former      CEO     of   Acclarent,     and   Fabian,   the
    company's former vice present of sales, played prominent roles in
    the   marketing    of    a    new   device     for    the   treatment    of   chronic
    sinusitis,   the       Relieva      Stratus    Microflow     Spacer     ("Stratus").
    Acclarent obtained preliminary approval to market Stratus for use
    as a "spacer" that would dispense a saline solution to the ethmoid
    sinuses and maintain an opening created by sinus surgery.                     Facteau
    and Fabian were convicted of unlawfully marketing Stratus to
    dispense a steroid, an "off-label" (i.e. unapproved) use, and fined
    $1 million and $500,000, respectively.
    A. Legal Framework Governing Medical Devices
    The FDCA has prohibited the distribution of adulterated
    or misbranded medical devices since its original enactment in 1938.
    With the Medical Device Amendments of 1976 ("MDA"), 
    Pub. L. No. 94-295, 90
     Stat. 539, "[i]n response to the mounting consumer and
    regulatory concern" over the lack of premarket review of medical
    devices, Congress broadened the statute's coverage to regulate the
    introduction      of    new   medical       devices    to   the   market   as   well.
    Medtronic, Inc. v. Lohr, 
    518 U.S. 470
    , 476 (1996).                  This statutory
    scheme classifies "devices intended for human use" based on the
    level of risk to the public, with Class III devices presenting the
    - 4 -
    most risk and correspondingly incurring the strictest regulation.
    21 U.S.C. § 360c(a)(1)(C); see Lohr, 
    518 U.S. at 476-77
    ; Buckman
    Co. v. Plaintiffs' Legal Comm., 
    531 U.S. 341
    , 343-44 (2001).
    Devices    not    on   the   market    before    1976    --   and   thus    all      new
    devices -- are initially placed by default in Class III. 21 U.S.C.
    § 360c(f)(1).
    1. Premarket Approval and § 510(k) Clearance
    Class III devices       must receive "premarket approval"
    ("PMA") from the FDA before they can legally be marketed.                            See
    § 360e(a)(2).       The PMA process is "time-consuming," Buckman, 
    531 U.S. at 348
    , because it requires the device's manufacturer to
    demonstrate a "reasonable assurance" that the device is safe and
    effective, 
    id. at 344
    .          See also Lohr, 
    518 U.S. at 477
    .
    A new device can avoid PMA review, however, if the FDA
    clears    it    through   the   "premarket       notification"      or    "§ 510(k)"
    process,1 which results in the device's reclassification from Class
    III to Class I or II.        Lohr, 
    518 U.S. at 478-79
    .          A new device can
    obtain    § 510(k)     clearance      if   the   FDA    determines       that   it    is
    "substantially equivalent" to a predicate device -- that is, a
    pre-1976 device or a post-1976 device that previously was moved
    from Class III to Class I or II.                 See § 360c(f)(1)(A)(ii); 21
    1 The "§ 510(k)" label for the premarket notification process
    reflects the original MDA section number for the process.      See
    Lohr, 
    518 U.S. at 478
    . That provision of the MDA is now codified
    at 
    21 U.S.C. § 360
    (k).
    - 5 -
    C.F.R. § 807.92(a)(3); Buckman, 
    531 U.S. at 345
    .            A new device is
    "substantially equivalent" to a predicate device if it (1) has the
    "same intended use" and (2) either has the same technological
    characteristics or the same safety and effectiveness profile.                21
    U.S.C. § 360c(i)(1)(A); 
    21 C.F.R. § 807.100
    (b).
    At least ninety days before introducing a new device to
    the market, a manufacturer seeking § 510(k) clearance must submit
    a premarket notification to the FDA.         
    21 C.F.R. § 807.81
    (a).       This
    premarket notification submission          includes a "510(k) summary"
    identifying    the   predicate    device     and   describing      the   device
    submitted for clearance, including its "intended use."               
    21 C.F.R. §§ 807.87
    (h), 807.92(a)(3)-(5).2       The submission must also contain
    "[p]roposed labels, labeling, and advertisements sufficient to
    describe the [device submitted for clearance], its intended use,
    and the directions for its use."       
    Id.
     § 807.87(e).
    2. "Intended Use"
    If the manufacturer of a device that is being marketed
    after    receiving   § 510(k)    clearance    makes   a   "major    change   or
    modification" in the device's intended use, the manufacturer must
    2 Instead of a 510(k) summary, the manufacturer may choose to
    submit a "510(k) statement" certifying that, if the FDA concludes
    that the device submitted for clearance is substantially
    equivalent to a predicate device, the manufacturer will provide
    safety and effectiveness information to support the FDA's finding
    within thirty days of a written request.           See 
    21 C.F.R. §§ 807.87
    (h), 807.93.
    - 6 -
    submit another premarket notification at least ninety days before
    marketing         the    device        for        the        new     use.        
    21 C.F.R. § 807.81
    (a)(3)(ii).            This new notification must include supporting
    data       showing      that     the        manufacturer            has     considered      the
    "consequences and effects the . . . new use might have on the
    safety and effectiveness of the device."                           
    Id.
     § 807.87(g).
    Whereas the FDA determines the intended use of a new
    device based solely on the proposed labeling submitted with its
    premarket        notification,        see    21    U.S.C.          § 360c(i)(1)(E)(i),       it
    determines the intended use of a device already                                 cleared for
    commercial distribution by reference to the "objective intent of
    the persons legally responsible for the labeling" of the device
    ("labelers"),            
    21 C.F.R. § 801.4
             (2020).3        Labelers'
    "expressions" -- such as "labeling claims, advertising matter, or
    oral        or     written       statements             by     [labelers]        or       their
    representatives" -- are one source of evidence for determining
    their "objective intent."              
    Id.
            Labelers' "objective intent" may
    also       be    established     by    the        "circumstances            surrounding     the
    distribution" of the device.                 
    Id.
    We refer to the version of the regulation governing the
    3
    "intended use" of devices already on the market that was in effect
    at the time appellants took the actions underlying their
    convictions.   The regulation was revised in August 2021.      See
    Regulations Regarding "Intended Uses", 
    86 Fed. Reg. 41401
    -02 (Aug.
    2, 2021) (codified at 
    21 C.F.R. § 801.4
    ).

    3. Adulteration, Misbranding, and Off-label Use
    The FDCA prohibits the "introduction or delivery for
    introduction             into       interstate            commerce          of
    any . . . device . . . that is adulterated or misbranded."                  
    21 U.S.C. § 331
    (a).      Violating this prohibition "with the intent to
    defraud or mislead" is a felony; a violation absent such intent is
    a misdemeanor.       
    Id.
     §§ 333(a)(1)-(2).          Misdemeanor offenses of
    commercially distributing adulterated or misbranded devices are
    strict-liability crimes.        United States v. Dotterweich, 
    320 U.S. 277
    , 284 (1943).
    A device is "adulterated" under § 351(f)(1)(B) if, as a
    Class III device, it is "required to have in effect an approved
    application    for   premarket     approval"   but    moves   in   interstate
    commerce without the required PMA.             See also United States v.
    Universal Mgmt. Servs., Inc. Corp., 
    191 F.3d 750
    , 754 (6th Cir.
    1999).   When a device that received an initial § 510(k) clearance
    is marketed for an intended use that represents a "major change or
    modification" from the cleared use without clearance for that
    change, the device is also considered "adulterated."                 
    21 C.F.R. § 807.81
    (a)(3)(ii).       As relevant here, a device is "misbranded" if
    the manufacturer fails to submit a "notice" to the FDA "as required
    by . . . section 360(k)."          
    21 U.S.C. § 352
    (o).          The "notice"
    referenced    by   the   statute   is   the   new   premarket   notification
    required when a device that previously received § 510(k) clearance
    - 8 -
    is about to have a "major change or modification in [its] intended
    use."    
    21 C.F.R. § 807.81
    (a)(3)(ii).
    In sum, it is unlawful for a manufacturer to commercially
    distribute a device for an intended use that represents a "major
    change or modification" from the specific use for which the device
    received   § 510(k)   clearance.        Such   off-label    marketing   would
    amount to the commercial distribution of an "adulterated" and
    "misbranded" device. At the same time, however, the FDCA expressly
    protects the "authority of a health care practitioner to prescribe
    or administer any legally marketed device to a patient for any
    condition or disease . . . ."           
    21 U.S.C. § 396.4
          Accordingly,
    medical professionals may lawfully prescribe and administer a
    device for an off-label use as long as that device has received
    § 510(k) clearance for any intended use.          See Buckman, 
    531 U.S. at 350
    ; Judge Rotenberg Educ. Ctr., Inc. v. U.S. Food & Drug Admin.,
    
    3 F.4th 390
    , 395 (D.C. Cir. 2021).         The statutory and regulatory
    scheme   governing    medical   devices    thus    limits   the   commercial
    distribution of devices to ensure that devices on the market are
    reasonably   safe    and   effective,    while    preserving   health   care
    4 We note that this section of the FDCA does contemplate some
    limitations on the authority conferred on health care providers
    with respect to "legally marketed device[s]." Section 396 states
    that the FDA's mandate not to interfere with the practice of
    medicine does not limit the agency's authority "to establish and
    enforce restrictions on the sale or distribution, or in the
    labeling, of a device . . . ." 
    21 U.S.C. § 396
    .

    professionals' discretion to prescribe and administer devices as
    they deem appropriate.      See Buckman, 
    531 U.S. at 349-50
    .
    B. Factual Background
    Appellants'    various    claims    on    appeal    require   us   to
    present the facts from two different perspectives.                 See United
    States v. Burgos-Montes, 
    786 F.3d 92
    , 99 (1st Cir. 2015).                 When
    recounting      the      evidence           relevant          to     Fabian's
    sufficiency-of-the-evidence challenges, we take the facts in the
    light most favorable to the verdict.          See United States v. Chan,
    
    981 F.3d 39
    , 45 (1st Cir. 2020).       For the other issues on appeal,
    we present the facts in a "balanced" way, taking an "objective[]
    view" of the evidence in the record.          Burgos-Montes, 
    786 F.3d at 99
     (first quoting United States v. Felton, 
    417 F.3d 97
    , 99 (1st
    Cir. 2005); then quoting United States v. Nelson-Rodríguez, 
    319 F.3d 12
    , 23 (1st Cir. 2003)).
    1. Development and Design of Stratus
    Acclarent   was    founded   in    2004   as    a   medical   device
    manufacturer focusing on devices for use in ear, nose, and throat
    ("ENT") care.   Facteau served as Acclarent's CEO from November
    2004 to December 2011, and Fabian was the company's vice president
    of sales from August 2007 to November 2011.              Since its founding,
    Acclarent's core products have been devices for use in balloon
    - 10 -
    sinuplasty, a surgical technique to treat chronic sinusitis by
    dilating the sinus openings with a small balloon.5
    However,   sinusitis    in   the   ethmoid   sinuses   is   not
    treatable with balloon sinuplasty.        As early as 2005, therefore,
    the members of Acclarent's Scientific Advisory Board ("SAB"), led
    by Facteau, discussed the possibility of developing a device that
    could provide relief for ethmoid sinusitis by delivering Kenalog-
    40 ("Kenalog") -- a topical steroid commonly used to reduce sinus
    inflammation -- directly to the ethmoid sinuses. These discussions
    culminated in the January 2006 approval by Facteau and other
    Acclarent officers of a project aimed at developing an "Ethmoid
    Sinus Stent" that, in the words of the project specification
    prepared as a roadmap for the design process, would be able "to
    deliver . . . Kenalog 40 for a duration of 14 days" "to the ethmoid
    [sinuses]."
    This project led to the design of a device that was
    ultimately marketed as Stratus.           The device featured a small
    balloon that was perforated with many tiny pores and was attached
    to a catheter.   The device would be inserted, with the balloon
    5 Sinusitis is the inflammation of the mucus membranes of the
    paranasal sinuses, see Stedman's Medical Dictionary 1777 (28th ed.
    2006), which are paired air-filled cavities in the bones of the
    face lined by mucous membranes, 
    id. at 1776
    . Balloon sinuplasty
    is offered as a less invasive surgical treatment for sinusitis
    than traditional endoscopic sinus surgery, which involves removal
    of tissue and bone.
    - 11 -
    uninflated, into the ethmoid sinus cavity by means of an access
    probe.   Once in situ, the balloon could be inflated by injecting
    a substance into it through the catheter.     When the balloon was
    filled in this way with Kenalog, the steroid would gradually
    diffuse out of the pores and bathe the ethmoid cavity over a
    roughly two-week period. The size of the pores had been calibrated
    to Kenalog's viscosity to achieve this result.     Indeed, the SAB
    discussed the importance of fine-tuning the pore size to ensure
    that, when inflated with Kenalog specifically, the steroid would
    not leak out of the balloon too quickly.
    2. Regulatory history of Stratus
    Although the Stratus device was designed for use in
    treating ethmoid sinusitis by delivering Kenalog to the ethmoid
    sinuses, the SAB and the project team, with Facteau's approval,
    decided to pursue a regulatory strategy of first gaining § 510(k)
    clearance for the device for use as a post-surgical spacer capable
    of releasing saline, and later seeking a second § 510(k) clearance
    for use as a system to deliver Kenalog to the ethmoid sinuses.
    In line with this strategy, Acclarent filed a premarket
    notification in August 2006, seeking § 510(k) clearance to market
    Stratus for use "as a postoperative spacer to maintain an opening
    to the ethmoid sinus within the first 14 days following surgery"
    and to "help[] to prevent obstruction."      Acclarent's submission
    identified the Rains Frontal Sinus Stent as the predicate device.
    - 12 -
    That device, which Acclarent stated was "substantially equivalent"
    to   Stratus      "in    indications      for        use     and   technological
    characteristics," is a spacer designed to minimize the post-
    operative    formation      of   adhesions      in    the    frontal    sinus   by
    maintaining an opening in the frontal sinus in the days following
    surgery.    In addition to use as a similar post-operative spacer in
    the ethmoid sinuses, Acclarent's submitted "Instructions for Use"
    for Stratus contemplated that, after the device had been inserted
    into the patient's ethmoid sinuses, the user would inject saline
    through    the   catheter    into   the   perforated        balloon    and,   after
    trimming away the catheter shaft, leave the device in place for up
    to fourteen days to "allow[] saline to moisten the [surrounding]
    area."     In September 2006, the FDA cleared Stratus for the use
    indicated in Acclarent's premarket notification.
    Although Acclarent's § 510(k) submission specifically
    contemplated that Stratus would be used with saline to moisten the
    ethmoid sinuses, it was understood by the SAB that the pores in
    the balloon were too large to allow saline -- a much less viscous
    fluid than Kenalog -- to gradually seep out over a two-week period.
    Rather, when injected, saline would rapidly flow out.                  The amount
    of saline that could fit in the Stratus balloon was also too small
    to be of much therapeutic value.
    Consistent      with     Acclarent's           two-step    regulatory
    strategy, it wrote to the FDA in April 2007 seeking to change
    - 13 -
    Stratus's labeling to add an indication to use Stratus "to irrigate
    the   sinus    space   for   diagnostic   and   therapeutic   procedures."
    Acclarent also sought to modify the instructions for use to state
    that the user could inject either saline or some "other therapeutic
    agent" into the catheter to inflate the balloon.
    The following month, the FDA denied Acclarent's request.
    The FDA sent a letter to Acclarent communicating that the proposed
    use of Stratus with a therapeutic agent might render it a drug-
    device "combination product" under 
    21 C.F.R. § 3.2
    (e), and hence
    subject to review both as a drug and as a device.         The letter also
    made clear that, even if the use of Stratus with a therapeutic
    agent did not render it a combination product, the proposed changes
    to the device's indications for use signaled a significant change
    or modification in the intended use of the device such that
    Acclarent would "need to submit a new 510(k)" and receive FDA
    clearance "prior to marketing [Stratus]" with the proposed changes
    in intended use.
    Notwithstanding this setback, in September 2007, with
    Facteau and Fabian in attendance, the steering committee tasked
    with developing and commercializing Stratus approved a proposal to
    market Stratus as a product to deliver Kenalog to the ethmoid
    sinuses, with plans for a commercial launch in the third or fourth
    quarter of 2008.       The committee recognized that for a commercial
    launch, Acclarent needed -- but lacked -- regulatory approval for
    - 14 -
    Stratus's use with a drug delivery indication.                 To that end, the
    committee made plans to submit a premarket notification seeking
    § 510(k) clearance to market Stratus for drug-delivery use, with
    the first quarter of 2008 as an optimistic target timeline.
    By   November    2007,     Acclarent     had     concluded    that   a
    successful § 510(k) submission for Stratus to be used for drug
    delivery    purposes    would   need   to     be   supported    by   appropriate
    clinical studies.       But the clinical study Acclarent was conducting
    had to be halted when, in December 2007, the FDA determined that
    it posed a significant risk to its subjects. To proceed, Acclarent
    needed to submit a proposal for a new study for the FDA's approval.
    Although the FDA approved a new study in August 2008, it too was
    halted -- in     July    2009 -- after      reports     of     adverse    events.
    Ultimately, Acclarent never completed an approved study to support
    Stratus's use with Kenalog and thus never filed a premarket
    notification for that intended use.
    3. Stratus Enters the Market
    Despite the lack of § 510(k) clearance for Stratus to be
    used with Kenalog, Acclarent proceeded with the plan to begin
    marketing the device for that use in the second half of 2008.                  With
    Facteau's    approval,     Acclarent    promoted     Stratus     for     use   with
    Kenalog at the July 2008 meeting of the Sinus Forum, an annual
    conference fully sponsored at the time by Acclarent, which Facteau
    and Fabian both attended.        One panel session featured, via video
    - 15 -
    feed, live demonstrations of Stratus by two surgeons, Dr. Douglas
    Hoisington    and   Dr.     Michael    Friedman,       whose   display    included
    filling the balloon with Kenalog.          The panel members explained how
    Stratus was designed to allow Kenalog to escape gradually into the
    ethmoid cavity while the device was in situ.               Hoisington, a member
    of Acclarent's SAB, also indicated that Stratus was not suited for
    its   cleared    use   by   demonstrating        how    saline     solution   would
    immediately run out of the device upon injection.                       Hoisington
    explained that the perforations in the balloon were designed to be
    small enough so that Kenalog, a more viscous fluid, would seep out
    slowly.    This live demonstration of Stratus was included in the
    2008 Sinus Forum at Facteau's direction.                 Facteau's goal was to
    showcase    Stratus's     use   with    Kenalog,       although    Hoisington   and
    Friedman themselves made the ultimate decisions to go ahead with
    their demonstrations.
    Around this time, Acclarent                also began commercially
    distributing Stratus on a limited market release, selling the
    device on a trial basis within a small number of sales territories
    and to a select group of doctors.               The limited launch of Stratus
    was   a   commercial    success.        Acclarent's       management     therefore
    decided to      expand the      marketing of Stratus to all potential
    customers.      Leading up to this full commercial launch, Facteau
    emailed several members of the SAB with a slide presentation on
    how Stratus would be commercially positioned.                     The presentation
    - 16 -
    described Stratus as "simply a way to obtain sustained drug
    delivery to [a] targeted sinus or sinus complex."               In this period,
    Facteau and Fabian also participated in a conference call with
    some of Acclarent's sales and training personnel, during which
    Facteau spoke about presenting Stratus to ENT surgeons as a way of
    delivering Kenalog to the ethmoid sinuses.
    Acclarent     launched       Stratus       for   full     commercial
    distribution at the 2008 meeting of the American Academy of
    Otolaryngologists        and     American        Rhinologic    Society         ("AAO
    conference"), which took place in September 2008.                As the annual
    meeting of the major professional organization for ENT surgeons,
    the    AAO    conference       provides     an     opportunity       for   device
    manufacturers to set up booths to exhibit their products and share
    information     about    these    products       with    potential     customers.
    Acclarent's booth was divided into two sides, one staffed by sales
    representatives focused on selling to the U.S. market, the other
    by    representatives    focused    on    the    international       market.      As
    directed by Acclarent regulatory officers, representatives on the
    U.S. side refrained from discussing off-label uses for Stratus,
    although the U.S.-side representatives also did not discuss or
    demonstrate Stratus for use as a spacer with saline.                    U.S.-side
    representatives were instructed to send attendees who asked about
    the uses for Stratus to the international side. The international-
    - 17 -
    side representatives would then share information about using
    Stratus for delivering Kenalog.
    4. Internal Training of Sales Representatives
    Acclarent required newly hired sales representatives to
    complete a month-long training program, including two weeks of
    on-site training, where they would learn how to promote Stratus
    and other Acclarent products.     Fabian led some of the training
    sessions and generally attended throughout to supervise.   Facteau
    also spoke and gave a presentation at some of these sessions.
    Trainees were taught how to present Stratus to ENT surgeons who
    were potential customers for the product by describing Stratus's
    features and benefits and how to operate it.
    The sales training staff and other presenters repeatedly
    conveyed to new hires that Stratus was designed to be used, and
    was expected to be used by most surgeons, to deliver Kenalog.
    Trainees were not taught about any clinical benefit that Stratus
    could provide when used as a spacer with saline, and they were
    trained to tell surgeons that although Stratus was cleared for use
    in the United States only as a spacer with saline, it was approved
    for use with Kenalog in Europe.       In addition, new hires were
    advised to ask surgeons "probing" or leading questions that would
    - 18 -
    prompt the surgeons to inquire about Stratus's potential use for
    steroid delivery to the sinuses.6
    Acclarent also provided sales representatives with a
    document -- reviewed and approved by Acclarent officers including
    Fabian -- to   guide    them   in    discussing   Stratus    with    potential
    customers and to "help them understand what they can and can't say
    about . . . Stratus"     and   its    intended    use.      This    "physician
    discussion guide"      recommended that      sales representatives        tell
    surgeons that, although Stratus was cleared only for use with
    saline, Acclarent "expect[ed]" that some surgeons "may want to
    infuse the device with a therapeutic fluid, steroid, antibiotic,
    antifungal, instead of saline."          The guide also noted that "the
    only agent that works optimally with [Stratus] is [Kenalog]."               By
    contrast, the guide provided no suggestions on how to explain the
    clinical benefit of using Stratus to deliver saline.                The guide
    also included "probing questions" that sales representatives might
    use to invite inquiries from surgeons about using Stratus with
    Kenalog.
    6 Facteau maintains that this training was properly designed
    to allow sales representatives to discuss using Stratus with
    Kenalog while remaining within the FDA's safe-harbor policy, which
    excludes manufacturer communications about off-label use of
    products from being considered evidence of a new intended use if
    those communications occur in response to unsolicited inquiries
    from health care professionals. See infra Section II.A.
    - 19 -
    Particularly       successful        sales    representatives       were
    invited by the sales team management, including Fabian, to share
    their    sales      techniques       and     marketing      materials    with   other
    representatives.           The promotional slide presentation for Stratus
    used    by    one   such      top-performing        sales   representative,     Jason
    Elmore, was widely shared in this way. This presentation described
    Stratus as "designed to elute Kenalog-40," that is, designed to
    allow the steroid to diffuse gradually out of the device.
    5. Promoting Stratus for Sale
    The Acclarent sales representatives who testified at
    trial reported that they were never given marketing materials for
    Stratus that described benefits from using the device as a spacer
    with saline.        By contrast, Acclarent made available a video for
    representatives to use in their pitches that depicted a surgeon
    implanting Stratus and filling the balloon with Kenalog. Acclarent
    also     provided         "sell    sheets" -- reviewed          and     approved     by
    Fabian -- that           sales    representatives       could    use    in   pitching
    Stratus.       These sell sheets included a picture of Stratus that
    appeared to show the balloon filled with Kenalog.
    The Acclarent sales representatives who testified about
    how they promoted Stratus to their customers uniformly stated that
    their pitches positioned Stratus as a device to deliver Kenalog,
    rather       than   as    a   spacer   with    saline.        This     testimony   was
    corroborated by testimony from multiple ENT surgeons who had been
    - 20 -
    approached by Acclarent sales representatives about Stratus.    The
    surgeons testified that the sales pitches they received positioned
    Stratus as a device for delivering Kenalog, not for use as a spacer
    with saline.
    These sales pitches bore abundant fruit.      From 2008,
    when Stratus was brought to market, until 2011, the final year
    appellants were employed at Acclarent, the gross revenue Acclarent
    earned from sales of Stratus totaled $33.5 million.
    6. Training for Surgeons Who Bought Stratus
    Acclarent provided training on how to use Stratus for
    the surgeons who    ordered the device.     The training sessions
    featured both slide presentations and a laboratory-based segment
    where participating surgeons had the opportunity to practice using
    the technology with cadaver heads or anatomically correct model
    heads.   Although the Acclarent trainers would inform participating
    surgeons that Stratus was cleared for use as a spacer with saline,
    the slide presentations did not describe how to use Stratus for
    its cleared use.    They did, however, tell surgeons how to use
    Stratus with Kenalog.   For example, one slide in the standard deck
    used for these training presentations featured a depiction of
    Stratus with the balloon filled with Kenalog.   Fabian reviewed and
    approved this slide deck.   During the laboratory-based segment of
    the training sessions, participating surgeons would usually learn
    - 21 -
    to use Stratus by filling the balloon with Kenalog or coffee
    creamer, a substance that looks like the steroid.7
    In line with this training and the sales pitches they
    received from Acclarent's sales representatives, the surgeons who
    bought Stratus predominantly used it off-label to deliver Kenalog
    or   some   other   drug.         Acclarent    was   aware   that   Stratus   was
    predominantly being used off-label since it notified the FDA of
    this fact in a March 2010 letter.8
    C. Procedural History
    In April 2015, a grand jury returned an eighteen-count
    indictment against Facteau and Fabian.                 In addition to counts
    alleging     conspiracy,     securities       fraud,   and   wire   fraud,    the
    indictment     included     ten    counts     specifically   directed   to    the
    unlawful off-label promotion of Stratus.                 Five counts charged
    appellants with commercially distributing an adulterated device
    with the intent to defraud and mislead in connection with five
    shipments of Stratus between October 2009 and February 2011.                  See
    7   Saline solution, by contrast, is clear.
    8 The Acclarent sales representatives who testified all
    reported that they only knew of surgeons who used the device with
    Kenalog and were aware of no surgeons who used it with saline.
    The record, however, does contain evidence of at least one doctor
    who used Stratus for its cleared use. Dr. Hoisington, a member of
    the Acclarent SAB, testified that he used Stratus as a post-
    operative spacer with saline in about 15 percent of the procedures
    he performed with the device. At other times, he used Stratus with
    an antifungal solution, an antibiotic solution, or Kenalog.
    Hoisington's most common use for Stratus was to deliver Kenalog.
    - 22 -
    
    21 U.S.C. §§ 331
    (a), 333(a)(1)-(2), 351(f)(1)(B).            Another five
    counts charged them with commercially distributing a misbranded
    device with the intent to defraud and mislead in connection with
    five other shipments of Stratus between December 2009 and May 2011.
    See 
    id.
     §§ 331(a), 333(a)(1)-(2), 352(a), 352(f), 352(o).                The
    charges    for   distributing   a    misbranded   device    alleged   three
    theories    of   misbranding:   false    and   misleading    labeling,    in
    violation of § 352(a); inadequate directions for use, in violation
    of § 352(f); and failure to file a required premarket notification,
    in violation of § 352(o).       The securities fraud charges and one
    wire-fraud count were dismissed on the government's motion before
    trial.
    After a thirty-day trial spanning June and July 2016,
    the jury acquitted      Facteau and Fabian        of the conspiracy      and
    remaining wire fraud counts but returned guilty verdicts on all
    ten counts charging them with distribution of an adulterated and
    misbranded device.9     However, the jury found that appellants had
    not committed those violations with the intent to defraud or
    mislead, thus finding them guilty only of the misdemeanor form of
    the offenses.
    9 With regard to the misbranding counts, the jury found that
    the government had proven misbranding for lack of regulatory
    clearance but had not proven its theories based on false or
    misleading labeling or inadequate directions for use.
    - 23 -
    In August 2016, appellants jointly moved for judgments
    of acquittal.      See Fed. R. Crim. P. 29(c).             In challenging their
    convictions,     appellants     raised     five    claims     relevant    to   this
    appeal:   (1) their       convictions     were     based     on   truthful,    non-
    misleading speech, thereby infringing their rights under the First
    Amendment;      (2) the    regulatory     scheme     under    which     they   were
    convicted is unconstitutionally vague; (3) the jury was improperly
    instructed on the evidence that may be considered in determining
    a device's intended use; (4) they lacked fair notice of the case
    against them, and thus were denied                 due process,       because the
    government proceeded on a novel prosecutorial theory and relied on
    internal company communications as evidence of intended use; and
    (5) the government presented insufficient evidence of statements
    promoting off-label use made by them or by Acclarent employees
    with respect to the ten shipments of Stratus that grounded their
    convictions.
    Rejecting these and other claims, the district court
    denied    appellants'       motion   in    September       2020.       The     court
    subsequently imposed a $1 million fine on Facteau and a $500,000
    fine on Fabian.     Appellants' timely appeals followed.
    II.
    On     appeal,    Facteau      and     Fabian    reiterate     numerous
    objections to their convictions, with some claims of error raised
    - 24 -
    jointly and others raised only by one of them.10             Fabian also
    challenges the amount of his fine. We begin with appellants' First
    Amendment   claims   and   then   consider   in   turn   their   arguments
    concerning the statutory concept of "intended use."11           Finally, we
    address Fabian's remaining claims, which challenge the sufficiency
    of the evidence and -- based on the Eighth Amendment's Excessive
    Fines Clause -- his $500,000 penalty.
    A. First Amendment Claim
    Facteau's First Amendment attack on his conviction takes
    the form of an instructional challenge.             He argues that the
    district     court   improperly      refused      appellants'     proposed
    instruction, which would have prevented the jury from considering
    any truthful, non-misleading promotional speech as evidence of the
    intended use of Stratus.     Instead, the court instructed the jury
    that it could consider such speech.          Facteau maintains that the
    court erred for two reasons.       First, using promotional speech as
    evidence of intended use in effect criminalizes that speech, in
    10Fabian incorporated by reference the arguments asserted in
    Facteau's brief. See Fed. R. App. P. 28(i). Hence, although for
    clarity's sake we discuss certain arguments as made by Facteau,
    our discussion of those arguments applies to both appellants. On
    the other hand, because Facteau did not join Fabian's brief, our
    discussion of issues raised by Fabian alone applies only to him.
    11 Fabian argues that as a matter of text and precedent,
    "intended use" encompasses only promotional speech, and thus the
    district court's instruction to the contrary was error.       Both
    appellants argue that the government's interpretation of "intended
    use" violates due process.
    - 25 -
    contravention of a growing body of law in the Second Circuit
    holding that truthful, non-misleading speech promoting off-label
    use is protected.   Second, because the FDA has adopted a policy
    that shields certain non-promotional speech from evidentiary use,
    allowing speech outside of this safe harbor to serve as evidence
    imposes an impermissible content-based burden on           "disfavored"
    speech, especially off-label promotional statements.
    After reviewing the district court's instructions and
    important background First Amendment principles, we consider each
    of these arguments in turn.
    1. Background
    At   trial,     appellants     proposed   that   the   court's
    instructions on the adulteration and misbranding charges include
    the statement that "truthful, non-misleading statements cannot
    give rise to a new intended use."      The court declined to give that
    instruction.   Instead, it told the jurors that, because "[i]t is
    not illegal in and of itself for a device manufacturer to provide
    truthful, not misleading information about an off-label use," they
    may not find a defendant guilty "based solely on truthful, non-
    misleading statements promoting an FDA-cleared or approved device,
    even if the use being promoted is not a cleared or approved use."
    Nevertheless, the court continued, jurors could consider truthful,
    non-misleading speech promoting off-label use as "evidence" in
    determining "whether the government has proved each element" of
    - 26 -
    the charged adulteration and misbranding offenses, "including the
    element of intent."       Appellants objected to the court's "failure
    to instruct the jury that truthful speech cannot be considered as
    evidence of intended use."
    2. Legal Analysis
    Facteau appears to take issue both with the district
    court's rejection of appellants' proffered instruction, as well as
    the instruction the court ultimately delivered to the jury. Where,
    as here, we consider a preserved claim that the trial court's
    instruction misstated the law, we review the court's instruction
    de novo.     United States v. Florentino-Rosario, 
    19 F.4th 530
    , 534
    (1st Cir. 2021).      We test whether the district court's refusal to
    give   appellants'      requested   instruction     constituted   reversible
    error by asking if that instruction was "(1) substantively correct
    as a matter of law, (2) not substantially covered by the charge as
    rendered, and (3) integral to an important point in the case so
    that   the   omission    of   the   instruction   seriously    impaired   the
    defendant's ability to present his defense."               United States v.
    McLellan, 
    959 F.3d 442
    , 467 (1st Cir. 2020) (quoting United States
    v. Baird, 
    712 F.3d 623
    , 628 (1st Cir. 2013)).                 We review the
    instruction     the   trial    court   did   give    for   whether   it   was
    "(1) misleading, unduly complicating, or incorrect as a matter of
    law; and (2) adversely affected the objecting party's substantial
    rights."     United States v. Figueroa-Lugo, 
    793 F.3d 179
    , 191 (1st
    - 27 -
    Cir. 2015) (quotation marks omitted) (quoting United States v.
    Stark, 
    499 F. 3d 72
    , 79 (1st Cir. 2007)).    In the present appeal,
    the question    under both inquiries    boils down to whether the
    district court erred because it should have instructed the jurors
    that they could not consider promotional statements as evidence of
    Stratus's intended use, rather than instructing the jurors that
    they could.
    To answer that question, we must note at the outset that,
    as a general matter, the First Amendment does not apply to the
    "evidentiary use of speech to establish the elements of a crime or
    to prove motive or intent."    Wisconsin v. Mitchell, 
    508 U.S. 476
    ,
    489 (1993). In Mitchell, the Court held that an aggravated battery
    defendant's First Amendment rights were not violated by using his
    statements to prove the racial motive that made him eligible for
    a sentence enhancement.     See 
    id. at 489-90
    .    In reaching that
    conclusion, the Court did not analyze whether this evidentiary use
    of the defendant's speech could satisfy some heightened standard
    of scrutiny.    Rather, the Court concluded that there was no First
    Amendment violation because the use of a defendant's speech as
    proof of his motive or intent simply does not implicate the First
    Amendment.    
    Id. at 489
    .
    Facteau's First Amendment argument is in obvious tension
    with the Court's holding in Mitchell.        For the crux of his
    instructional error claim, he argues that because a manufacturer's
    - 28 -
    truthful, non-misleading speech promoting the off-label use of a
    device is protected under the First Amendment, the district court
    should have instructed the jury that, in effect, it may not
    consider any such speech as evidence of the device's intended use.
    To do otherwise, the court's instruction would need to withstand
    heightened scrutiny, which Facteau argues it could not.              But, as
    indicated, Mitchell makes clear that the First Amendment offers no
    protection against using otherwise protected speech as evidence of
    intent or to establish the elements of a crime.              Facteau offers
    two explanations for why the Court's holding in Mitchell does not
    reach this case, and hence appellants' proposed instruction was
    compelled by the First Amendment.
    i.   Whether Using Promotional Speech as Evidence of
    Intended Use De Facto Criminalizes That Speech
    Facteau first argues that the First Amendment does not
    permit   the   factfinder    here   to   consider    off-label   promotional
    speech as evidence of intended use by pointing to the Second
    Circuit's decision in United States v. Caronia, 
    703 F.3d 149
     (2d
    Cir. 2012), and its progeny in Amarin Pharma, Inc. v. FDA, 
    119 F. Supp. 3d 196
     (S.D.N.Y. 2015).       In a significant decision limiting,
    for the first time, the use of off-label promotional speech in the
    context of misbranding prosecutions, the court in Caronia held
    that   the   defendant's    conviction    violated    the   First   Amendment
    because the prosecution "repeatedly argued that [he] engaged in
    - 29 -
    criminal conduct by promoting and marketing the off-label use
    of . . . an FDA-approved drug," leaving "the jury to understand
    that [his] speech was itself the proscribed conduct."             
    703 F.3d at 161
    .        Because it found that the defendant "was prosecuted [for]
    precisely his speech in aid of pharmaceutical marketing," 
    id. at 162
    , the court applied heightened scrutiny under Central Hudson
    Gas & Electric Corp. v. Public Service Commission of New York, 
    447 U.S. 557
     (1980), and concluded that the prosecution did not survive
    that standard, Caronia, 
    703 F.3d at 164-69
    .12
    Taking   his   cue   from   Caronia,   Facteau   contends   that
    permitting the jury to consider his off-label promotional speech
    in assessing his guilt under the FDCA amounts to the de facto
    criminalization of his protected speech, creating a "backdoor"
    through which the government may sneak past the First Amendment's
    reach and punish appellants simply for the things they said about
    Stratus.       In Caronia, the government argued, as it does here, that
    it was merely relying on the defendant's speech as evidence of his
    intended use for the drug, rather than punishing him for his
    Applying Caronia as binding precedent, the district court
    12
    in Amarin sided with a drug manufacturer in its pre-enforcement
    challenge against the FDA, declaring that the manufacturer had a
    First Amendment right to "engage in truthful and non-misleading
    speech promoting the off-label use of [its product]" and that "such
    speech may not form the basis of a prosecution for misbranding."
    
    119 F. Supp. 3d at 237
    .
    - 30 -
    speech.13 See 
    703 F.3d at 160-62
    . While stressing that its opinion
    did not question the general principle that speech can constitute
    evidence of intended use, the Caronia majority was not persuaded
    that the government's use of speech was limited to evidentiary
    purposes in that case.      
    Id.
       It pointed, among other things, to
    the government's sole reliance on the defendant's statements to
    establish his criminal liability, the government's profligate use
    of his statements in its summation to the jury, and the court's
    jury instructions, which "flatly stated . . . that pharmaceutical
    representatives     are   prohibited   from   engaging   in   off-label
    promotion" and "left the jury to understand that Caronia's speech
    was itself the proscribed conduct."        
    Id. at 161
    .   It also bears
    emphasis that the defendant in Caronia was a sales representative,
    whose sole job function was to make promotional statements about
    the product.      Moreover, the government's theory of misbranding
    focused on the defendant's statements promoting off-label uses and
    the consequence that the drug's labeling did not bear "adequate
    directions for use."      See 
    21 U.S.C. § 352
    (f)(1).
    13 Likewise, in dissent, Judge Livingston posited that the
    government's reliance on the defendant's speech served no purpose
    other than as evidence of the drug's intended use, and she pondered
    whether, under the majority's rule, any prosecution could rely on
    off-label promotional speech as evidence of the defendant's
    intended use for a potentially misbranded product. Caronia, 
    703 F.3d at 172-77
    .
    - 31 -
    Though Facteau's reliance on Caronia is understandable,
    that case is meaningfully different from the one at hand and
    provides us with no basis to depart from the rule in Mitchell that
    the evidentiary use of speech does not violate the First Amendment.
    Unlike in Caronia, the government's case here relied on a wide
    array of evidence, which included not only promotional speech about
    off-label    uses    but    also     internal   communications         regarding
    regulatory   and    marketing      strategy   and    the   product's    physical
    design.     It is not the case, as it was in Caronia, that the
    government set out to punish appellants for what they said about
    the product; rather, what appellants said about Stratus simply
    shed light on how they intended it to be used.                   The district
    court's instructions made as much clear, specifying that "[i]t is
    not illegal in and of itself for a device manufacturer to provide
    truthful, not misleading information about an off-label use" and
    that the jury may not find a defendant guilty "based solely on
    truthful, non-misleading statements promoting an FDA-cleared or
    approved device, even if the use being promoted is not a cleared
    or approved use."
    Moreover,      the   government's       successful   theories    for
    misbranding and adulteration did not turn on whether Acclarent's
    statements left Stratus without adequate directions for use, as
    was the case in Caronia.         Though the government did present that
    theory of misbranding to the jury, the jury rejected that approach
    - 32 -
    and instead found appellants guilty of misbranding because Stratus
    lacked the proper regulatory clearance -- a theory of misbranding
    less   intertwined   with    appellants'   speech.     And,   unlike   the
    defendant in Caronia, both Facteau and Fabian were high-level
    executives at Acclarent responsible not just for what was said
    about Stratus publicly but also for internal decisions on product
    design and regulatory strategy (in the case of Facteau), as well
    as sales strategy (in the case of both).
    In short, Caronia does not render appellants' proposed
    instruction an accurate statement of law that properly captured
    the nuances of the First Amendment interests at stake in this case.
    Calculated to cut off any evidentiary use of off-label promotional
    speech, appellants' preferred instruction would have removed this
    case from the teachings of Mitchell and placed it within the domain
    of Caronia without the facts to justify such a move.          We discern
    no error in the district court's refusal to take that step, nor in
    the instructions it ultimately handed down, which better respected
    the    sensitive   balance   between   protecting    promotional   speech
    without shielding such speech from evidentiary value.
    In so holding, we note that we are in alignment with our
    sister circuits -- including the Second.        The courts to consider
    the issue have uniformly concluded that using speech merely as
    evidence of a misbranding offense under the FDCA does not raise
    First Amendment concerns.       See, e.g., Whitaker v. 
    Thompson, 353
    - 33 -
    F.3d     947,     953     (D.C.    Cir.       2004)      (holding           that     it    is
    "constitutionally         permissible"        to   use     a    seller's       claims      as
    evidence of intended use, even when                      doing so       "renders      [the]
    otherwise       permissible   act       [of   selling      the       product       with   FDA
    approval] unlawful"); Nicopure Labs, LLC v. FDA, 
    944 F.3d 267
    , 282
    (D.C. Cir. 2019) (reaffirming Whitaker);                  United States v. LeBeau,
    
    654 F. App'x 826
    , 830-31 (7th Cir. 2016).                        Indeed, as we have
    noted, the Caronia court assumed that evidentiary use of statements
    to prove FDCA violations would be permissible under the First
    Amendment but concluded on the facts that the prosecution did not
    use speech in that way.           See 
    703 F.3d at 161
    .                See also U.S. ex
    rel. Polansky v. Pfizer, Inc., 
    822 F.3d 613
    , 615 n.2 (2d Cir. 2016)
    ("Caronia left open the government's ability to prove misbranding
    on a theory that promotional speech provides evidence that a drug
    is intended for a use that is not included on the drug's FDA-
    approved label.").
    We     find    relevant       and      persuasive         this     consistent
    authority from other circuits that the First Amendment is not
    implicated by the evidentiary use of truthful, non-misleading
    promotional speech to establish a drug's intended use to obtain a
    conviction under the FDCA.              Appellants' convictions fall soundly
    within    that     domain.        The    trial     court       did    not     criminalize
    appellants'      speech    itself,      instructing        the       jury    to    consider
    promotional speech only insofar as it shed light on appellants'
    - 34 -
    intended use for Stratus.           Accordingly, Facteau's reliance on
    Caronia fails.
    ii. Whether the FDA's Safe Harbor               Policy    Subjects
    Promotional Speech to a Discriminatory Burden
    Facteau's additional First Amendment argument targets
    FDA   guidance    explaining    when   truthful,     non-misleading   speech
    regarding off-label uses will not be considered evidence of a
    product's intended use.        In Facteau's telling, this "safe harbor"
    draws content-based distinctions between favored and disfavored
    speech, burdening speech that affirmatively promotes an off-label
    use of a device -- by considering it as evidence of intended use
    -- while excluding evidentiary uses of science-based responses to
    unsolicited questions from physicians regarding off-label use and
    the distribution of certain scientific literature.              He contends
    further that, because these burdens are content- and viewpoint-
    based,   they    cannot   survive   heightened     scrutiny   and   therefore
    violate the First Amendment.
    Facteau's argument draws upon Supreme Court precedent
    recognizing      that   policies    singling   out    certain   speech   for
    regulatory burdens -- based on the content of that speech -- are
    subject to heightened judicial scrutiny.             See, e.g., Sorrell v.
    IMS Health Inc., 
    564 U.S. 552
    , 565 (2011) (holding that a law
    "designed to impose a specific, content-based burden on protected
    expression" is subject to "heightened judicial scrutiny"); United
    - 35 -
    States v. Playboy Ent. Grp., Inc., 
    529 U.S. 803
    , 812 (2000)
    ("[C]ontent-based burdens must satisfy the same rigorous scrutiny
    as . . . content-based bans.").        In Sorrell, for instance, the
    Court   held    unconstitutional   a    Vermont    law   that   required
    pharmaceutical marketers to obtain a physician's consent before
    they could use data about his prescribing practices to inform their
    marketing strategy but imposed no similar requirement on using
    that data for other purposes, such as for research or patient
    education.     See 
    564 U.S. at 559-60, 565
    .       Facteau contends that
    the FDA's safe harbor operates in similar fashion by using the
    content of a medical product manufacturer's speech to determine
    whether that speech will bear the burden of potentially being used
    as evidence of intended use.
    We understand Facteau's theory to fit into his First
    Amendment instructional error claim by supplying another rationale
    for the correctness of appellants' rejected instruction, even
    though seemingly out of step with Mitchell, in the context of this
    case.   Although it is generally permissible for a jury to consider
    promotional speech as evidence of intent, any evidence so presented
    to the jury because it is not protected by the safe harbor would
    be the product of a government policy that unequally foists the
    burden of potential evidentiary use upon certain speech based on
    its content.    Thus, the court should have instructed the jury to
    - 36 -
    exclude all evidence derived from appellants' promotional speech,
    as appellants requested.
    The government asserts that this argument is forfeited
    because it was not raised below.         We agree.     Although appellants
    made general First Amendment objections to the court's instruction
    that the jurors may consider promotional speech as evidence of
    intent, and at times couched their arguments in terms of content-
    and viewpoint-based discrimination, they never suggested that the
    FDA's     safe-harbor    guidance    constituted     such   discrimination.
    Indeed, Facteau's trial counsel insisted -- over the government's
    objection -- that the court adopt an instruction modeled on one of
    the guidance documents, hardly suggesting that appellants viewed
    the safe harbor as odious to protected speech.14            Because "a party
    is not at liberty to articulate specific arguments for the first
    time on appeal simply because the general issue was before the
    district court,"        United States v. Slade, 
    980 F.2d 27
    , 31 (1st
    14 We recognize that Facteau's counsel requested this
    instruction as a "fallback" after the trial court rejected
    appellants' view that any consideration of truthful, non-
    misleading statements to show improper intent violated the First
    Amendment. Nonetheless, Facteau's counsel expressly agreed that
    appellants were "not objecting to this instruction as-is over and
    beyond the views they already have of the First Amendment in this
    case," thereby disclaiming any First Amendment argument beyond
    their objection rooted in Caronia.
    - 37 -
    Cir. 1992), we will apply plain error review to assess Facteau's
    unpreserved argument.15
    Under that standard, Facteau "must show '(1) that an
    error occurred (2) which was clear or obvious and which not only
    (3) affected [his] substantial rights, but also (4) seriously
    impaired the fairness, integrity, or public reputation of judicial
    proceedings.'"      United States v. Nieves-Meléndez, 
    58 F.4th 569
    ,
    579 (1st Cir. 2023) (quoting United States v. Merced-García, 
    24 F.4th 76
    , 79-80 (1st Cir. 2022)).              An error is only clear or
    obvious when it is "'indisputable' in light of controlling law."
    Merced-García, 24 F.4th at 80 (quoting United States v. Rabb, 
    5 F.4th 95
    , 101 (1st Cir. 2021)); see also United States v. Grullon,
    
    996 F.3d 21
    ,   33   (1st   Cir.    2021)   ("[P]lain   error   cannot   be
    found . . . absent clear and binding precedent." (quoting United
    States v. Marcano, 
    525 F.3d 72
    , 74 (1st Cir. 2008) (per curiam))).
    15At times, Facteau's briefing regarding this additional
    First Amendment argument appears to stray from the framing of an
    instructional challenge, engaging instead in a more fundamental
    and broad-based attack on the FDA's safe harbor policy.       But
    Facteau never presented any such argument to the district court
    and does not suggest before us how the safe harbor policy
    concretely affected his prosecution beyond the conclusory
    assertion that "[t]he government's . . . enforcement approach
    improperly affected every aspect of the trial here." Accordingly,
    we would deem any such theory waived.       See United States v.
    Zannino, 
    895 F.2d 1
    , 17 (1990) ("[I]ssues adverted to in a
    perfunctory manner, unaccompanied by some effort at developed
    argumentation, are deemed waived."). Instead, we construe
    Facteau's argument as part of his primary instructional error
    challenge, reviewable for plain error.
    - 38 -
    Facteau principally points to two guidance documents
    issued by the FDA -- a draft document from 2011 ("2011 guidance")
    and a revised draft from 2014 ("2014 guidance") -- as the source
    of the safe harbor policy that, he urges, results in a burden on
    the speech excluded from the safe harbor by subjecting only such
    "disfavored" speech to the peril of being used as evidence of
    intended use.16        The 2011 guidance sets out standards for how
    manufacturers        should     respond   to     unsolicited     requests     for
    information about off-label uses for their devices.               See U.S. Food
    &    Drug    Admin.,    Draft     Guidance     for   Industry    Responding   to
    Unsolicited Requests for Off-Label Information About Prescription
    Drugs and Medical Devices (2011).            For example, the 2011 guidance
    recommended that manufacturers respond to such requests with "non-
    biased information or data" concerning the off-label use.                
    Id. at 8
    .     The    2011     guidance    also   recommended     that    responses    to
    unsolicited requests be generated by scientific personnel rather

    16
    guidance that he claims imposes a First Amendment-violative burden
    on speech, a 2009 FDA guidance document on recommended practices

    by the FDA regarding Washington Legal Foundation v. Henney,

    Facteau devotes much of his briefing to establishing
    that the FDA's safe harbor amounts to content-based discrimination
    that cannot withstand heightened scrutiny.                       But this argument
    depends     upon    the    premise     that    speech      outside         of    the   safe
    harbor -- and thus subject to potential evidentiary use -- suffers
    a "burden" raising First Amendment concerns in the first place.
    On plain error review we must satisfy ourselves that this threshold
    assertion     is    "'indisputable'       in       light   of    controlling           law."
    Merced-García, 24 F.4th at 80 (quoting Rabb, 5 F.4th at 101).                           That
    is a tall order, considering the clarity with which Mitchell
    - 40 -
    establishes that using speech as evidence ordinarily does not run
    afoul of the First Amendment.   Because Facteau's argument fails to
    clear the threshold hurdle of demonstrating that the safe harbor
    policy "burdens" protected speech within the meaning of the First
    Amendment, we need not analyze whether the safe harbor policy
    imposes such a burden by drawing content-based distinctions or
    whether those distinctions would satisfy heightened scrutiny.
    To start, Facteau's argument fundamentally misconstrues
    the nature of the FDA's safe harbor.        Far from burdening what
    device manufacturers may say, the safe harbor guidance expands,
    rather than contracts, the domain of speech that the government
    shields from being used as evidence.     If, as a general matter, the
    evidentiary use of speech discussing off-label use does not raise
    First Amendment concerns, then presumably a policy that limits the
    consideration of such speech as evidence of intended use does not
    raise First Amendment concerns either.17
    Neither of the cases upon which Facteau relies persuades
    us otherwise.   See Sorrell, 
    564 U.S. 552
    ; Playboy, 
    529 U.S. 803
    .
    While these cases certainly establish the general principle that
    17We note, moreover, that it is far from clear that the FDA's
    safe harbor policies make content-based distinctions on speech.
    In many cases, such as the 2011 guidance on unsolicited questions
    about off-label use, it is the circumstances under which a
    statement arises, and not the content of the statement itself,
    that determine whether the FDA deems that statement open for
    evidentiary use.
    - 41 -
    some regulations on speech impose burdens sufficient to raise First
    Amendment concerns, they fall far short of the "clear and binding
    precedent" necessary on plain error review to sustain Facteau's
    argument that the FDA's safe harbor fits that mold.             Grullon, 996
    F.3d at 33.
    The regulations found to impermissibly burden speech in
    both Sorrell and Playboy took much more direct aim at protected
    speech -- and imposed far more onerous restrictions on it -- than
    does the FDA's safe harbor, even in Facteau's telling.                The law
    challenged     in   Sorrell   prohibited     pharmaceutical    sellers    from
    using, or even receiving, information about doctors' prescribing
    practices to inform their sales pitches.            
    564 U.S. at 564-66
    .      In
    Playboy, a regulation aimed at preventing broadcasts of adult
    entertainment from reaching children produced a sweeping partial
    ban of such programming except during late evening hours.                   
    529 U.S. at 811-15
    .
    By contrast, at most, the FDA's safe harbor puts the
    sellers   of   medical   products    on    notice    about   which   of   their
    statements the government deems most probative of that product's
    intended use.18     That is no different than how a defendant's speech
    18Facteau assumes that all off-label speech, whether within
    the safe harbor or otherwise, has equal potential to be probative
    of intended use.    But that assumption defies the common sense
    behind the FDA's safe harbor policy, which reflects the agency's
    judgment about the circumstances in which a device seller's off-
    label speech is more indicative of its state of mind than other
    - 42 -
    may be probative of the racial animus behind an assault, see
    Mitchell, 
    508 U.S. at 489
    , or soldiers "announcing their sexual
    orientation" was probative of whether they had violated "Don't
    Ask, Don't Tell" prior to its repeal, see Cook v. Gates, 
    528 F.3d 42
    , 62-64 (1st Cir. 2008).      As we have noted, if the FDA's safe
    harbor marks a departure from the Mitchell baseline at all, it is
    only because it removes certain speech from government scrutiny,
    rather than heaping more scrutiny upon the speech that falls
    outside the safe harbor.
    It is of course true that medical device sellers, aware
    that their speech may become evidence          of intended use, will
    necessarily choose their words carefully when promoting their
    products.    But such efforts do not amount to a "burden" on free
    expression   when   it   is   conduct -- in   this   case,   introducing
    misbranded or adulterated devices into commerce -- and not speech
    that the law aims to control.      We have said that such "incidental
    effects" on speech arising from laws directed at non-speech conduct
    "do[] not . . . implicate the First Amendment."          Wirzburger v.
    Galvin, 
    412 F.3d 271
    , 278 (1st Cir. 2005) (citing Arcara v. Cloud
    instances of speech. For instance, the FDA's 2011 draft guidance
    distinguishes between requests for off-label information that are
    "solicited" versus "unsolicited."   When a physician or patient
    comes to a manufacturer unbidden and asks about the off-label
    application of a product, nothing about a manufacturer responding
    truthfully inherently suggests that it intends the product to be
    used off-label.
    - 43 -
    Books, Inc., 
    478 U.S. 697
    , 698 (1986)).              See also Cook, 
    528 F.3d at 63
     (use of speech as evidence of violation of law "aimed at
    eliminating certain conduct . . ., not at restricting speech,"
    does not burden speech).
    We thus find no merit in Facteau's apparent contention
    that, because the FDA's safe harbor policy shields some speech
    from evidentiary use, the jury should have been instructed to
    disregard all promotional speech as evidence of intended use. And,
    having rejected the Caronia argument as well, we conclude that
    Facteau's First Amendment arguments fail to support departing from
    Mitchell's longstanding rule that using speech as evidence of
    intent does not implicate the First Amendment.                        Accordingly,
    neither the district court's rejection of appellants' proposed
    instruction nor its decision to instead instruct the jury that it
    could consider speech for evidentiary purposes was in error.
    B. Instructional Error Claim Regarding "Intended Use"
    Having     decided    that     the    First   Amendment        poses   no
    obstacle    to   the   government's      evidentiary      use    of    appellants'
    off-label    promotional         speech,     we    turn    now        to    Fabian's
    countervailing argument that the jury should have been instructed
    that it may consider only such evidence to determine a product's
    intended use.
    - 44 -
    1. Background
    At the pre-trial charge conference, appellants' counsel
    objected   to    the   district     court's     proposed   instructions     on
    "intended use" on the ground that those instructions did not convey
    to the jury that when the government alleges that a medical device
    serves an intended use for which it has not been approved, that
    "intended use must be based only on external promotional conduct."
    Appellants asked the court to instead instruct the jury that only
    statements made to potential customers bear on a device's "intended
    use" and that the jurors therefore should not consider internal
    company    documents      and   communications,      responses   to    doctor-
    initiated inquiries, and scientific information disseminated in
    academic and educational venues in evaluating the question of
    "intended use."
    The    court    declined    to     give   appellants'      requested
    instruction and rejected their challenge to its own instruction.
    It thus instructed the jury as follows on how a device's "intended
    use" is to be determined outside of the § 510(k) process:
    The term "intended use" refers to the
    objective intent of the manufacturer or seller
    of the device.   The intent is determined by
    such person's expressions or may be shown by
    the     circumstances      surrounding     the
    distribution of the device.     This objective
    intent may, for example, be shown by labeling
    claims, advertising matter, or oral or written
    statements   by   such    persons   or   their
    representatives.    It may be shown by the
    circumstances that the device is, with the
    - 45 -
    knowledge   of    such persons   or   their
    representatives, offered and used for a
    purpose for which it is neither labeled nor
    advertised. . . .
    Mere knowledge that doctors are using a device
    for purposes other than its labeled use does
    not give rise to a new intended use.      Off-
    label promotional statements can constitute
    evidence   of  an   intended   use,   although
    truthful, non-misleading speech alone cannot
    be the basis for a criminal conviction. . . .
    After the court charged the jury, appellants objected to
    the court's "failure to instruct the jury that in determining
    intended use, the jury must look solely to the external promotional
    activities surrounding the distribution of a device."            Appellants
    renewed this instructional challenge in their motion for judgments
    of acquittal.
    In ruling on appellants' motion, the district court gave
    two reasons for rejecting this instructional challenge.                 First,
    the instruction as given was consistent with the plain language of
    the description of "intended use" set out in 
    21 C.F.R. § 801.4
    .
    Second,   the   position      stated        in   appellants'         requested
    instruction -- that   the   only    relevant     evidence   of   a    device's
    intended use is the manufacturer or seller's external promotional
    statements -- finds no support in caselaw.
    2. Legal Analysis
    On appeal, Fabian reiterates his claim that the district
    court's instruction was legally erroneous and that the court should
    - 46 -
    have instead instructed the jury that only external promotional
    statements could be considered in determining whether Stratus was
    being improperly marketed for a new intended use.          Fabian relies
    first on the definition of "intended use" in § 801.4, which refers
    to the "objective intent" of the labelers of the device.        He claims
    that reference necessarily limits the focus to external marketing
    and promotional statements.      Fabian also relies on what he asserts
    are prior judicial interpretations of "intended use" that define
    that term to encompass only promotional statements communicated to
    potential customers.
    This preserved instructional claim thus requires us to
    determine whether Fabian's proposed instruction or the contrary
    instruction   given   by   the   district   court   properly   stated   the
    relevant law. Accordingly, our review is de novo. See Florentino-
    Rosario, 19 F.4th at 534.19
    Fabian's argument based on the definition of "intended
    use" in 
    21 C.F.R. § 801.4
     is easily dispatched.          As the district
    court persuasively reasoned, the concept of "objective intent"
    simply means that there must be "outward expressions" of such
    19 The government argues that we should apply plain error
    review because Fabian did not specifically object to the district
    court's failure to give his requested instruction after the court
    charged the jury. See United States v. Pérez-Rodríguez, 
    13 F.4th 1
    , 16 (1st Cir. 2021).     The government, however, is mistaken.
    Fabian did object to the court's refusal to instruct the jury that
    intended use is to be determined solely by reference to external
    promotional statements.
    - 47 -
    intent and not merely "unexpressed thoughts" within the mind of an
    individual.      United States v. Facteau, No. 15-cr-10076-ADB, 
    2020 WL 5517573
    , at *17 (D. Mass. Sept. 14, 2020).                        This notion of
    intent,     which judges a person's mental state by its outward
    manifestations through speech and conduct, is a familiar concept
    in the law.          See, e.g., Restatement (Second) of Contracts § 18
    cmt. a (Am. L. Inst. 1981) ("Assent to the formation of an informal
    contract is operative only to the extent that it is manifested.").
    Communications and conduct internal to Acclarent's operations were
    not   any     less    "objective"    because     they       were    not   directed      at
    potential customers for Stratus or at the public in general.
    Moreover, as the district court noted, the plain text of
    the   then-current         version   of   § 801.4      did    not    limit      relevant
    manifestations        of   "objective     intent"      in    the    way   that    Fabian
    suggests. The regulation stated that objective intent may be shown
    by "expressions" such as "oral or written statements by [labelers]
    or    their     representatives,"         with   no     indication         that    these
    statements must be directed to individuals outside the company.
    The regulation also embraced, as a manifestation of "objective
    intent," "the circumstances surrounding the distribution" of a
    device -- including          evidence     that   the    device      was,       "with   the
    knowledge of [labelers] or their representatives, offered and used
    for a purpose for which it is neither labeled nor advertised."
    Thus,   the    regulation      expressly     contemplated          that    a   labeler's
    - 48 -
    "objective intent" -- and hence a device's intended use -- could
    be proven with evidence beyond the external promotional statements
    of a device manufacturer's officers and employees.
    Fabian's argument from precedent is equally unavailing.
    Neither of the out-of-circuit cases he highlights stand for the
    principle on which he relies, namely that only public-facing
    promotional statements can provide evidence of a device's intended
    use.    Indeed, in United States v. Articles of Drug for Veterinary
    Use, 
    50 F.3d 497
     (8th Cir. 1995), the Eighth Circuit expressly
    held that a seller's "intended application" of a product -- in
    that case, a suspected adulterated new animal drug -- may be
    determined by reference to evidence from "any relevant source,"
    including, but not limited to, external promotional statements.
    
    Id. at 499-500
    .   To    be   sure,   promotional   statements   proved
    exceptionally relevant in that case as the facts centered on
    literature accompanying the product, see 
    id. at 499-500
    , but the
    court did not purport to hold that only such promotional material
    is probative of the intended use of a product regulated by the
    FDCA.
    The Fourth Circuit's decision in Brown & Williamson
    Tobacco Corp. v. FDA, 
    153 F.3d 155
     (4th Cir. 1998), is similarly
    unhelpful to Fabian.        Although the panel observed that "no court
    has ever found that a product is 'intended for use' [as a drug or
    device] . . . absent manufacturer claims as to that product's
    - 49 -
    use," 
    id. at 163
     (quoting Coyne Beahm, Inc. v. FDA, 
    966 F. Supp. 1374
    , 1390 (M.D.N.C. 1997)), the decision does not support Fabian's
    view that a court may not consider other sources of evidence.
    Rather, the case merely reinforces the obvious point that labeling
    and external statements are important sources to consider.
    Moreover, Fabian's position is contradicted by other
    precedent, including from our own court.       We long ago stated that,
    in   determining   a   product's    intended   use   for   purposes   of   a
    misbranding conviction, courts are "free to look to all relevant
    sources in order [to] ascertain . . . 'intended use.'" V.E. Irons,
    Inc. v. United States, 
    244 F.2d 34
    , 44 (1st Cir. 1957) (emphasis
    added).     While the specific sources we relied on in V.E. Irons
    were the literature distributed and the oral representations made
    in connection with the sale of the misbranded drugs, we did not
    thereby imply any limitation on the "all relevant sources" standard
    we announced.
    This broad standard has been endorsed by multiple other
    circuits.    For instance, the Federal Circuit, in Allergan, Inc. v.
    Athena Cosmetics, Inc., 
    738 F.3d 1350
     (Fed. Cir. 2013), stated
    that the intended use of a product "may be 'derived or inferred
    from labeling, promotional material, advertising, or any other
    relevant source.'"     
    Id. at 1357
     (quoting United States v. Storage
    Spaces Designated Nos. 8 and 49 Located at 277 East Douglas, 
    777 F.2d 1363
    , 1366 (9th Cir. 1985)). The court expressly "disagree[d]
    - 50 -
    with [the defendant] that the only relevant evidence is labeling
    and marketing," and it considered the company's internal "training
    of resellers" when analyzing the question of objective intent. 
    Id.
    Similarly, in United States v. An Article of Device, 
    731 F.2d 1253
    ,
    1257 (7th Cir. 1984),    the Seventh Circuit determined that a
    chiropractic instrument was intended to be used as a medical device
    by examining the instructions that accompanied the device, the
    "financial arrangements through which chiropractors were trained
    in the use of the [device]," and testimony from chiropractors about
    how they used it.   See also Action on Smoking & Health v. Harris,
    
    655 F.2d 236
    , 239 (D.C. Cir. 1980) ("[I]t is well established that
    the 'intended use' of a product, within the meaning of the [FDCA],
    is determined from its label, accompanying labeling, promotional
    claims, advertising, and any other relevant source."     (Internal
    quotation marks omitted) (emphasis added)); United States v. An
    Article . . . Consisting of 216 Cartoned Bottles, More or Less,
    Sudden Change, 
    409 F.2d 734
    , 739 (2d Cir. 1969) ("It is well
    settled that the intended use of a product may be determined from
    its   label,   accompanying   labeling,    promotional   material,
    advertising and any other relevant source."   (Emphasis added)).
    In sum, we do not find Fabian's proposed understanding
    of "intended use" under § 801.4 persuasive, and we discern no error
    in the district court's interpretation of that term as stated in
    - 51 -
    its instruction to the jury.     Accordingly, Fabian's instructional
    challenge fails.
    C. Due Process Claims Regarding "Intended Use"
    Both Facteau and Fabian contend that their convictions
    were obtained in violation of the Fifth Amendment's Due Process
    Clause because "intended use," as that term is used in the relevant
    FDCA    provisions      and      accompanying        regulations,        is
    unconstitutionally vague.       Facteau makes a further due process
    claim that, because the government and courts at the time of his
    conduct took the position that only external marketing statements
    promoting off-label use can be considered as evidence of a new
    intended use, his prosecution under a novel and more expansive
    interpretation of intended use denied him the fair notice required
    by due process.
    Appellants   raised    both     due   process   claims   in   the
    district court, and we therefore review them de novo.          See United
    States v. Silva, 
    794 F.3d 173
    , 177 (1st Cir. 2015).
    1. Unconstitutional Vagueness Claim
    The government violates the Due Process Clause if it
    "tak[es] away someone's life, liberty, or property under a criminal
    law so vague that it fails to give ordinary people fair notice of
    the conduct it punishes, or so standardless that it invites
    arbitrary enforcement."   Johnson v. United States, 
    576 U.S. 591
    ,
    595 (2015) (citing     Kolender v. Lawson, 
    461 U.S. 352
    , 357-58
    - 52 -
    (1983)); accord Frese v. Formella, 
    53 F.4th 1
    , 6 (1st Cir. 2022)
    (identifying "lack of notice" and the prospect of "discriminatory
    enforcement"   as    the   hallmarks     of    an   unconstitutionally         vague
    statute).      In   most   contexts,     the    test      for    unconstitutional
    vagueness is whether the challenged law is so indefinite that it
    "fails to provide a person of ordinary intelligence fair notice of
    what is prohibited."       Frese, 53 F.4th at 6 (quoting United States
    v. Williams, 
    553 U.S. 285
    , 304 (2008)).                   For provisions that
    concern   economic    regulation,      however,     the    test    is   whether    a
    "business person of ordinary intelligence would understand" what
    conduct is prohibited -- a "less strict vagueness test."                  Vill. of
    Hoffman Ests. v. Flipside, Hoffman Ests., Inc., 
    455 U.S. 489
    , 499,
    501 (1982) (emphasis added).20
    Appellants     offer   two    rationales        to    support      their
    contention   that    the   legal    framework       under       which   they   were
    20 Courts are less likely to conclude that statutes and
    regulations   "addressed   to   sophisticated   businessmen   and
    corporations" are unconstitutionally vague because of an
    assumption that, given the "complexity" of economic regulation,
    such parties "necessarily consult counsel in planning their
    activities," and some "administrative process" will often be
    available "to secure advisory interpretations of the statute [or
    regulation]" at issue. United States v. Lachman, 
    387 F.3d 42
    , 57
    (1st Cir. 2004). By contrast, vagueness review is more stringent
    when the challenged laws implicate the First Amendment's
    protections for speech. See FCC v. Fox Television Stations, Inc.,
    
    567 U.S. 239
    , 253-54 (2012) (noting that a more "rigorous"
    vagueness inquiry is appropriate "to ensure that ambiguity does
    not chill protected speech"). As explained above, however, the
    adulteration and misbranding offenses underlying appellants'
    convictions do not raise First Amendment concerns.
    - 53 -
    convicted -- and particularly the term "intended use" -- is so
    vague as to violate the Due Process Clause.     First, they argue
    that the broad scope of evidence that § 801.4 allows to determine
    intended use makes the term unconstitutionally vague.      Second,
    they argue that there is a history of inconsistent agency and
    judicial interpretations of "intended use" that indicates that the
    term is impermissibly vague.   We address each of these arguments
    in turn.
    i. Evidence of "Intended Use" Under § 801.4
    Appellants contend that the government's position that
    a device manufacturer's "intended use" for a device may take into
    account "'all circumstances' from 'any relevant source' relating
    to the [device]" -- an interpretation adopted by the district
    court in its jury instructions -- renders the FDCA provisions
    underlying their convictions unconstitutionally vague.21      They
    argue that, when such a wide array of evidence may be used to
    21 The government does not dispute appellants' depiction of
    its interpretation of the regulation and, indeed, the record
    reflects the broad construction they posit.        In its closing
    argument, for example, the government told the jurors that they
    could "look at all of the circumstances surrounding the
    distribution of the device to figure out what would be the intended
    use of the device." As recounted above, the district court's jury
    instructions also reflected this interpretation. The court told
    the jurors that the intended use for a device "refers to the
    objective intent" of the device manufacturer or seller, which
    intent   is  "determined   by"   the   manufacturer   or   seller's
    "expressions" and "the circumstances surrounding the distribution
    of the device."
    - 54 -
    support    a   finding   of   "intended     use" -- and          thus    criminal
    liability -- manufacturers       lack    fair    notice     of     the    conduct
    prohibited under the adulteration and misbranding offenses, and
    the   government's   authority    to    prosecute   violations           of   those
    offenses improperly lacks any limiting standards.
    The   vagueness    doctrine    is    primarily    concerned         with
    whether the language of a legal provision is sufficiently clear.22
    Necessarily, then, appellants must show that § 801.4's definition
    of "intended use" -- which looks to the "objective intent" of the
    seller as determined by his "oral or written statements" and "the
    circumstances surrounding the distribution" of the device -- is so
    unclear that it does not give fair warning of when the seller will
    be found to have an intended use for their device that differs
    from the use for which it has been cleared.
    The vagueness doctrine's focus on the language of a penal
    22
    law is evident from the earliest cases developing the doctrine.
    See, e.g., Connally v. Gen. Constr. Co., 
    269 U.S. 385
    , 391 (1926)
    ("That the terms of a penal statute creating a new offense must be
    sufficiently explicit to inform those who are subject to it what
    conduct on their part will render them liable to its penalties is
    a well-recognized requirement, . . . and a statute which either
    forbids or requires the doing of an act in terms so vague that men
    of common intelligence must necessarily guess at its meaning and
    differ as to its application violates the first essential of due
    process of law." (Emphases added)); McBoyle v. United States, 
    283 U.S. 25
    , 27 (1931) ("[I]t is reasonable that a fair warning should
    be given to the world in language that the common world will
    understand, of what the law intends to do if a certain line is
    passed. To make the warning fair, so far as possible the line
    should be clear." (Emphasis added)).

    Appellants fail to explain how, as a textual matter, the
    law lacked sufficient clarity to apprise them of when they would
    be criminally liable for distributing a device with an unapproved
    intended use. The FDCA and its implementing regulations make clear
    that manufacturers must submit a new premarket notification before
    they commercially distribute a device for an intended use that
    represents a "major change or modification in the intended use of
    the device" from the cleared use.             
    21 C.F.R. § 807.81
    (a)(3)(ii).
    And, as noted in our discussion of Fabian's instructional-error
    claim,    "objective   intent,"      which    § 801.4    relies   upon    in      its
    definition of "intended use," is a familiar and well-established
    concept in the law.      Indeed, the Supreme Court has indicated that
    the objective intent standard is sufficiently determinate for
    purposes of the vagueness doctrine.           See Williams, 
    553 U.S. at 306
    (holding that "[w]hether someone . . . had an intent is a true-
    or-false     determination,    not    a   subjective     judgment"     and    hence
    specifies      a   sufficiently      determinate       standard   of     criminal
    culpability).      Moreover, the regulation goes on to explain that
    such objective intent may be reflected in a seller's "statements"
    or   other    "circumstances   surrounding       the    distribution"        of   the
    device.      To be sure, the provision casts a wide net.             It does so,
    however, in language that fairly apprises the reader of the broad
    range of conduct that may reasonably reflect a device's intended
    use.
    - 56 -
    Especially given the less stringent vagueness test that
    applies to economic regulation, appellants have failed to show
    that "intended use," as that term is defined in § 801.4, is
    unconstitutionally vague.    At most, there may be some uncertainty
    under § 801.4 about when, in a close case, there will be sufficient
    evidence to prove that a manufacturer marketed a device for an
    off-label intended use.     That type of uncertainty, however, does
    not give rise to a valid vagueness claim.   As the government points
    out, a penal law is impermissibly vague when it fails to give "fair
    notice of what is forbidden," United States v. Morosco, 
    822 F.3d 1
    , 5 (1st Cir. 2016), not simply when it may be difficult to
    determine whether, given the evidence in a particular case, the
    elements of the offense defined in the law have been proved, see
    Williams, 
    553 U.S. at 306
     ("What renders a statute vague is not
    the possibility that it will sometimes be difficult to determine
    whether the incriminating fact it establishes has been proved; but
    rather the indeterminacy of precisely what that fact is.").
    Moreover, we think it worth noting that this was not a
    close case.   The government produced copious evidence from a wide
    range of sources -- from the design of Stratus, to the history of
    its product development within Acclarent, to how it was promoted
    to potential customers -- that established an objective intent by
    Acclarent's management that Stratus be used for delivering Kenalog
    rather than for its cleared use as a postoperative spacer with
    - 57 -
    saline.     Whatever indeterminacy there might be about how much and
    what kinds of evidence would be sufficient to prove a new intended
    use in a close case, appellants cannot rely on that hypothetical
    indeterminacy to make a vagueness claim here.               Cf. McCoy v. Town
    of Pittsfield, 
    59 F.4th 497
    , 509 (1st Cir. 2023) ("[A] 'plaintiff
    who engages in some conduct that is clearly proscribed cannot
    complain of the vagueness of the law as applied to the conduct of
    others.'"    (Quoting Holder v. Humanitarian L. Project, 
    561 U.S. 1
    ,
    18-19 (2010))).
    ii. Inconsistent Agency and Judicial Interpretations
    The   Supreme   Court    recognized   in    Johnson        that   one
    powerful indication that a law is unconstitutionally vague is when
    the law has "proved nearly impossible to apply consistently,"
    engendering "pervasive disagreement" among courts about even "the
    nature of the inquiry [a court applying the law] is supposed to
    conduct and the kinds of factors [the court] is supposed to
    consider."     576 U.S. at 601 (internal quotation marks omitted).
    We   have    similarly   suggested    that   where     an     agency    "issues
    contradictory or misleading public interpretations" of its own
    regulation, "there may be sufficient confusion for a regulated
    party to justifiably claim a deprivation of fair notice." Lachman,
    
    387 F.3d at 57
    .
    Appellants raise an inconsistent interpretation argument
    along these lines by alleging that both the FDA and the courts
    - 58 -
    have shifted in their interpretation of the FDCA, demonstrating
    that the term "intended use" is unconstitutionally vague because
    it has proven subject to varying interpretations.                  On appellants'
    telling, the courts and the FDA have at times embraced the narrow
    view that a medical product's "intended use," is revealed only by
    promotional    statements.      At    other    times,       however,   they    have
    endorsed the more expansive view that evidence of a product's
    intended use can come from any relevant source, including not just
    promotional speech but internal communications, product design,
    and other conduct.
    Appellants suggest that perhaps Caronia is to blame for
    this shift.    To be sure, as we have already observed, Caronia was
    a significant opinion, articulating a limit on the government's
    use of off-label promotional speech as the basis of a conviction
    under the FDCA.    It is reasonable to think that the government, as
    well   as   courts,   may    have    grown     more    cautious     about     using
    promotional speech alone as the basis of a conviction following
    Caronia.      However,   that   caution       does    not   mean    that    Caronia
    fundamentally altered the way the government or courts construe
    the applicable law and regulations, opening a door to using non-
    promotional statements and other conduct as evidence of intended
    use that was previously (in appellants' telling) closed.
    Upon our examination of judicial and agency precedent,
    we are unpersuaded that there has been such a sea change in the
    - 59 -
    interpretation of the FDCA that appellants were deprived of fair
    notice of what the law prohibited.           We begin with the caselaw.
    Appellants misread the precedent in claiming that courts
    have exhibited pervasive disagreement about how to understand the
    determinants of "intended use."         Neither of the cases appellants
    cite exemplify, as they suggest, courts narrowing permissible
    evidence of intended use to external manufacturer claims only.
    See Brown & Williamson, 
    153 F.3d 155
    ; Am. Health Prods. Co. v.
    Hayes, 
    574 F. Supp. 1498
    , 1505 (S.D.N.Y. 1983), aff'd per curiam,
    
    744 F.2d 912
     (2d Cir. 1984).
    As we explained with regard to Fabian's instructional
    challenge, the Brown & Williamson court observed that courts
    typically   do    not   determine   intended     use   without    considering
    manufacturers' external claims, but it did not endorse the distinct
    notion that only such claims may be considered as evidence of
    intended use.     See 155 F.3d at 163.        The court in American Health
    Products    Co.    v.   Hayes   likewise      endorsed   the     unremarkable
    proposition that "marketing representations" are                 important   in
    determining intended use but did not say that they alone may be
    considered.      See 
    574 F. Supp. at 1505
    .
    In fact, as noted above, multiple federal courts of
    appeal, in decisions stretching back decades, have taken the
    position that finders of fact may determine "intended use" by
    considering evidence from a broad range of sources, including
    - 60 -
    evidence   other   than    promotional    claims    and    other      externally
    directed manufacturer claims.         See, e.g., V.E. Irons, 
    244 F.2d at 38
    ; Allergan, 
    738 F.3d at 1357
    ; Article of Device, 
    731 F.2d at 1257
    ; Action on Smoking, 
    655 F.2d at 239
    ; Article of 216 Cartoned
    Bottles, 409 F.2d at 739.
    As   for   appellants'      suggestion        that   the    FDA     has
    previously   interpreted    the   determinants      of    "intended     use"    as
    encompassing only external promotional claims, the main example
    they cite comes from a 2002 letter from Daniel E. Troy ("Troy
    letter"), then Chief Counsel of the FDA.             The letter contained
    Troy's response to requests for information from Applied Digital
    Systems, see 21 U.S.C. § 360c(g), regarding whether a device the
    company planned to market was a "medical device" under the FDCA
    because it was "intended for use in the diagnosis of disease or
    other   conditions,   or   in   the   cure,   mitigation,       treatment,      or
    prevention of disease," see 
    21 U.S.C. § 321
    (h)(1)(B). In analyzing
    two intended uses that the company proposed for the device, Troy
    stated that "[i]t is well settled that intended use is determined
    with reference to marketing claims."
    The Troy letter does not show that the FDA previously
    embraced the narrow interpretation of "intended use."                 First, the
    Troy letter does not say that external promotional claims are the
    exclusive source of permissible evidence.                As with the caselaw
    discussed above, a statement that marketing claims are essential
    - 61 -
    in determining intended use does not foreclose reliance on other
    factors.23    Second, per regulation, the views expressed in the Troy
    letter cannot be attributed to the agency itself, but only to an
    FDA employee.     The letter did not offer an advisory opinion under
    
    21 C.F.R. § 10.85
    , and it was therefore an "informal communication"
    that "[did] not necessarily represent the formal position of FDA,
    and [did] not bind or otherwise obligate or commit the agency to
    the views expressed."    
    Id.
     at § 10.85(k).   More fundamentally, the
    fact that the Troy letter was an informal communication to a
    private regulated entity means that the principle we articulated
    in Lachman, discussed above, does not apply here. As we emphasized
    there, "non-public statements" by agency employees do not "create
    the kind of confusion that supports a finding of a due process
    violation."    
    387 F.3d at 58
    .
    23The other FDA guidance documents that appellants point to
    as examples of the FDA adopting the narrow interpretation of the
    determinants of "intended use" are inapposite for the same reason.
    Thus, while one guidance document explained that the "FDA has
    consistently prohibited the promotion of . . . unapproved uses of
    approved products," nowhere does the document suggest that such
    promotional claims are the sole permissible evidence of intended
    use.   See Final Guidance on Industry-Supported Scientific and
    Educational Activities, 
    62 Fed. Reg. 64074
    , 64081 (Dec. 3, 1997).
    Similarly, while another guidance document mentioned product
    labeling and information about the product disseminated by
    manufacturers among the "materials [that] can create new intended
    uses," the document does not state that these two types of
    materials are the only permissible determinants of intended use.
    See Citizen Petition Regarding the FDA's Policy on Promotion of
    Unapproved Uses of Approved Drugs & Devices, 
    59 Fed. Reg. 59820
    ,
    59821 (Nov. 18, 1994).

    2. Fair Warning Claim
    Facteau presses an additional due process argument along
    similar lines.       He suggests that in the wake of Caronia, the
    government has undertaken an interpretive pivot in its enforcement
    of the FDCA, expanding its definition of intended use to account
    for the fact that post-Caronia it may be more difficult to carry
    a   conviction    based    on   promotional        statements        alone.      Since
    appellants' conduct occurred before Caronia but their prosecution
    came after that decision, Facteau argues that he was convicted by
    retroactive      application     of        a    novel    and     more       expansive
    interpretation     of     the   relevant         FDCA   provisions       and     their
    accompanying regulations and thus lacked "fair warning" of what
    the law requires.
    A defendant may not be convicted under a penal law that,
    "either   standing      alone   or    as       construed,"     did    not     make   it
    "reasonably clear at the relevant time that the defendant's conduct
    was criminal."     United States v. Lanier, 
    520 U.S. 259
    , 267 (1997).
    Thus, a defendant has been deprived of "the right of fair warning"
    when he is convicted under a novel judicial construction of a
    statute or other law that works "an unforeseeable and retroactive
    judicial expansion" of the law's scope. Bouie v. City of Columbia,
    
    378 U.S. 347
    , 352 (1964); see also Lanier, 
    520 U.S. at 266
     ("[D]ue
    process bars courts from applying a novel construction of a
    criminal statute to conduct that neither the statute nor any prior
    - 63 -
    judicial decision has fairly disclosed to be within its scope.").
    Likewise, where an agency expands its interpretation of a statute
    or regulation to cover conduct not previously covered, it may not
    penalize a regulated party for engaging in the newly covered
    conduct prior to that change in interpretation. See Fox Television
    Stations, 567 U.S. at 254-58; cf. United States v. Anzalone, 
    766 F.2d 676
    , 681-82 (1st Cir. 1985) (concluding that defendant's
    conviction violated due process because he lacked fair notice of
    a   newly   expanded    interpretation       of    the   Currency   Transaction
    Reporting Act).
    Facteau cannot avail himself of this doctrine.                      As
    indicated    in   our   earlier   discussion       of    appellants'   vagueness
    claim, neither the FDA nor the courts, prior to Caronia, espoused
    an interpretive approach that limited the determinants of intended
    use   to     manufacturers'       external        claims,    and    thus     their
    interpretation of the law has not broadened following that decision
    in the way Facteau claims.            Beyond those discussed above in
    connection with appellants' vagueness claim, Facteau cites four
    cases as examples of decisions where courts have adopted a narrow
    interpretation of the determinants of "intended use."                      None of
    these cases, however, suggests that a product's intended use must
    be determined exclusively by reference to external promotional
    claims.     Moreover, we find it telling that though Facteau cites
    all of these cases as examples of the supposed pre-Caronia rule,
    - 64 -
    some were decided after that case, refuting the suggestion that
    Caronia spurred a change in how the law is interpreted.                 Rather,
    the authority consistently shows, before Caronia and since, that
    relevant evidence of intended use can come from many sources.
    As we have explained, the Eighth Circuit did not hold in
    Articles of Drug, 
    50 F.3d 497
    , that the intended use of a medical
    product    may    be    determined   only   by    reference   to    promotional
    materials.    Indeed, the court expressly affirmed that the seller's
    intended use for a product "may be derived from any relevant
    source."   
    Id. at 500
    .      Similarly, in United States v. US Stem Cell
    Clinic, LLC, 
    998 F.3d 1302
    , 1311 (11th Cir. 2021), the court
    suggested that the government must produce marketing materials
    that support its allegations of a drug's intended use but nowhere
    stated that only marketing materials are permissible.                 Likewise,
    the district court's statement in U.S. ex rel. Modglin v. DJO
    Global Inc. that a device manufacturer "can only be liable for
    violating the FDCA if it markets or promotes the device for [an
    off-label use]," does not limit the range of evidence to such
    statements.       
    48 F. Supp. 3d 1362
    , 1371 (C.D. Cal. 2014) (citing
    Carson v. Depuy Spine, Inc., 
    365 F. App'x 812
    , 815 (9th Cir.
    2010)).    Whether we agree with these latter two cases that the
    government       must   produce   evidence       of   promotional   speech   to
    establish a product's intended use is not at issue in this appeal.
    For the purposes of this case, it is sufficient that we have found
    - 65 -
    no    authority   indicating   that    only   promotional   statements    are
    relevant to intended use.24
    We thus discern no interpretive pivot following Caronia.
    Accordingly, the interpretation of the determinants of "intended
    use" under which Facteau was prosecuted was not a novel and more
    expansive interpretation of which he lacked fair warning.
    Facteau's fair warning claim fails for a further reason.
    As the Seventh Circuit has explained, the "uncertainty that is
    inevitable in legal standards . . . often is offset by [actual]
    notice, so that people need not guess what is required of them."
    United States v. Caputo, 
    517 F.3d 935
    , 941 (7th Cir. 2008).            Hence,
    where an agency has "alerted [regulated parties] to its view of
    their legal obligations," and the regulated parties nonetheless
    choose "to go their own way," they are thereby "[taking] a risk
    and [cannot] then say 'we didn't know' or 'the regulation left us
    scratching our heads.'"        
    Id.
         Here, Acclarent received actual
    notice.    In May 2007, in response to Acclarent's request to add to
    Stratus's labeling an indication for the delivery of diagnostic
    and    therapeutic   substances   to    the   sinuses,   the   FDA   notified
    Acclarent that the proposed change appeared to be a change in
    24 Facteau's fourth case, Association of American Physicians &
    Surgeons, Inc. v. FDA, is irrelevant as it did not concern intended
    use at all.     See 
    226 F. Supp. 2d 204
    , 216-18 (D.D.C. 2002)
    (explaining that the question of intended use was not at issue and
    that the case concerned "a different section of the FDCA
    entirely").
    - 66 -
    intended use requiring Acclarent to "submit a new 510(k) and
    receive Food and Drug Administration clearance prior to marketing
    [Stratus] with [the proposed] changes."25   Having been notified of
    the government's view, Facteau's complaint of unfair surprise at
    being prosecuted for marketing Stratus to deliver Kenalog despite
    Acclarent's failure to obtain such approval rings hollow.
    D. Fabian's Remaining Arguments
    Finally, we turn to several issues that Fabian raises
    separately: that the evidence is insufficient in the absence of
    promotional statements specifically pertaining to the ten Stratus
    shipments underlying the convictions; that Fabian's conviction is
    improper absent any evidence that he personally participated in
    submitting Stratus's § 510(k) filings, which he characterizes as
    the actus reus of the crime; and that his $500,000 fine is
    excessive under the Eighth Amendment.
    1. Sufficiency of the Evidence Arguments
    Fabian makes two arguments to challenge the sufficiency
    of the evidence. Although the government argues that Fabian failed
    25 Facteau argues that because the May 2007 letter indicated
    that Stratus must receive § 510(k) clearance for use with Kenalog
    prior to its "marketing" for that use, it did not provide actual
    notice that Acclarent could not commercially distribute Stratus
    with that intended use as opposed to making promotional statements
    about that intended use. We do not agree. In context, "marketing"
    was a reference to placing Stratus on the market, not to promoting
    Stratus.    In any event, Acclarent did not receive additional
    clearance before its sales representatives began promoting Stratus
    for use with Kenalog.
    - 67 -
    to preserve one of them -- the inadequacy of the evidence on the
    crime's actus reus -- we disagree and, accordingly, apply de novo
    review to both sufficiency claims.26          See United States v. Cadden,
    
    965 F.3d 1
    , 10 (1st Cir. 2020).        Our task is therefore to "assess
    the   record   evidence   'in   the     light    most     favorable     to   the
    prosecution' and affirm so long as the 'body of proof, as a whole,
    has sufficient bite to ground a reasoned conclusion that the
    government proved each of the elements of the charged crime beyond
    a reasonable doubt.'"     
    Id. at 10
     (quoting United States v. Lara,
    
    181 F.3d 183
    , 200 (1st Cir. 1999)).
    i. Evidence of Intended Use Accompanying Each Shipment
    Fabian   argues   that    the     government   needed   to    adduce
    evidence -- in the form of commercial expression -- accompanying
    each of the ten shipments of Stratus underlying the conviction to
    26The government asserts that Fabian is not entitled to de
    novo review of the actus reus claim because he did not specifically
    brief that claim in the district court. We have held, however,
    that a Rule 29 motion raising a "general challenge to the adequacy
    of the evidence preserves for de novo review 'the full range of
    challenges, whether stated or unstated.'"        United States v.
    Marston, 
    694 F.3d 131
    , 134 (1st Cir. 2012). Only if a defendant
    "give[s] specific grounds for a Rule 29 motion" is there a waiver
    of "all grounds not specified." 
    Id.
     Although appellants' Rule
    29(c) motion specifically challenged only the evidence pertaining
    to the ten shipments of Stratus, their Rule 29(a) motion
    "assert[ed] a general challenge to the sufficiency of the
    Government's evidence on all counts." We consider this statement
    adequate to generally preserve the issue of sufficiency of the
    evidence. See 
    id. at 135
     (urging "in case of doubt to treat an
    ambiguous motion . . . as 'general'" to avoid "penaliz[ing] the
    giving of examples" or "creat[ing] a trap for the unwary defense
    lawyer").
    - 68 -
    establish the intended use of that particular shipment.                   The
    government having failed to carry this burden, Fabian argues, his
    conviction stands on insufficient evidence.          We disagree.
    To start, Fabian's argument as presented seems to depend
    upon his theory that only outward promotional speech is probative
    of a product's intended use.      Accordingly, Fabian asserts that the
    government   needed   to,   but   did   not,   put   forward   evidence    of
    statements accompanying each shipment of Stratus promoting that
    shipment for use with Kenalog rather than saline.               As we have
    explained, Fabian is incorrect that only promotional statements
    can establish a product's intended use, and his argument thus
    falters out of the gate.
    In any case, we do not agree with Fabian's underlying
    premise that the government must always put forward evidence
    establishing the intended use of each individual shipment, even
    when the evidence shows that the whole point of the enterprise was
    to market an adulterated and/or misbranded device.             Fabian seems
    to suggest that it is the act of shipping, itself, that renders a
    device adulterated or misbranded, such that the circumstances of
    each shipment are essential to the status of the device.            But that
    is not so.     We have long said that § 331(a) "prohibit[s] the
    introduction into interstate commerce of [products] which at the
    time of introduction" are adulterated or misbranded.              Penobscot
    Poultry Co. v. United States, 
    244 F.2d 94
    , 97 (1st Cir. 1957).
    - 69 -
    In other words, a device must in its "present state" at the time
    of shipping be adulterated or misbranded, but the circumstances of
    the shipment need not render it so.    
    Id.
    To be sure, the immediate circumstances accompanying a
    device's shipment may provide evidence of its intended use, but so
    may all sorts of evidence from before (or after) the shipment that
    establish the essential fact under § 331(a): that the device was
    misbranded or adulterated when shipped.      Here, the record evidence
    reflects a scheme that from the beginning was aimed at marketing
    Stratus to deliver Kenalog rather than saline, including evidence
    that Stratus did not even work to deliver saline, was specifically
    designed with Kenalog in mind, and was promoted with a sales
    strategy devised to get physicians to associate Stratus with
    Kenalog and consider using it for drug delivery.     As the Acclarent
    executive in charge of sales, Fabian oversaw much of this activity.
    A reasonable juror could examine this evidence and find that any
    Stratus shipped by Acclarent in the midst of that scheme had an
    intended use of delivering Kenalog.
    In arguing that the evidence needed to establish the
    intended use of each shipment, Fabian largely relies on Kordel v.
    United States, 
    335 U.S. 345
     (1948), and, once again, on the Eighth
    Circuit's decision in Articles of Drug, 
    50 F.3d 497
    .     Neither case
    lends Fabian the support he claims.     Kordel does not, as Fabian
    suggests, stand for the broad principle that any conviction for
    - 70 -
    violating the FDCA by marketing an unapproved product requires
    evidence (of promotional statements or otherwise) accompanying
    that specific shipment to establish the intended use of the shipped
    product.    The defendant in Kordel was convicted of misbranding a
    drug by marketing it with an inadequate or false label.                   Whether
    promotional       statements     had    to    directly    accompany    individual
    shipments of a product to establish liability was a relevant issue
    in that case because the statute defined a drug label to include
    "written,       printed,    or   graphic      matter . . . accompanying      such
    article."       Kordel, 
    335 U.S. at
    347 (citing 
    21 U.S.C. § 201
    (m))
    (emphasis added).          Here, by contrast, Fabian is not accused of
    mislabeling a drug product, and thus the scope of the statutory
    requirement      that   statements       or   other   materials   "accompany"     a
    product    to    be   considered       part   of   the   product's    labeling   is
    irrelevant.      The statutory and regulatory scheme at hand speaks of
    no similar requirement that materials or other evidence must
    "accompany" the individual product unit to shed light on its
    intended use.27
    Nor does Articles of Drug lend any persuasive force to
    Fabian's argument.          The court did express that "[p]romotional
    27Our decision in Nature Food Centres, Inc. v. United States,
    
    310 F.2d 67
     (1st Cir. 1962), is similarly inapposite. That case,
    too, discussed the requirement that materials "accompany" shipped
    products in the specific context of labeling, drawing that
    requirement directly from the statutory and regulatory scheme.
    
    Id. at 70-71
    .
    - 71 -
    materials are relevant to intent so long as they are currently
    being distributed with the product . . . ."            Articles of Drug, 
    50 F.3d at 500
    .     But nothing in the court's analysis suggests that
    the caveat that promotional material be "current" -- which also
    harkened to the requirement that drug labeling "accompany" the
    product, see 
    21 U.S.C. § 201
    (m) -- should extend to other forms of
    evidence.    To the contrary, the court expressly recognized that
    "intended application for a product may be derived from                   any
    relevant source."      Articles of Drug, 
    50 F.3d at 500
     (emphasis
    added).     Indeed, it even held that past promotional efforts not
    tied to a particular shipment can be probative of a product's
    intended use in appropriate cases.          
    Id.
       As we have discussed, the
    evidence in this case may not be contemporaneous with individual
    shipments, but it provided ample reason for jurors to conclude
    that the intended use of Stratus, generally, was to deliver
    Kenalog, and thus that each shipment of Stratus underlying Fabian's
    conviction shared that intended use.
    ii. Evidence of Actus Reus
    In his second sufficiency challenge, Fabian argues that
    the government failed to produce evidence that would allow a
    rational jury to conclude that he participated in the actus reus
    of the crime, which, in his telling, was Acclarent's § 510(k)
    filings with the FDA.        Fabian asserts that, because no record
    evidence    showed   that   he   participated     in   preparing   regulatory
    - 72 -
    filings for the company, he could not have committed what he argues
    is the criminal act underlying the conviction.             Nor, as vice
    president of sales, could he have been considered a responsible
    corporate agent for that act.       See United States v. Dotterweich,
    
    320 U.S. 277
    , 284 (1943); United States v. Park, 
    421 U.S. 658
    ,
    673-74 (1975).    The government counters that the true actus reus
    of   violating   § 331(a)   is   "caus[ing]    the   introduction    of   an
    adulterated or misbranded article into interstate commerce."              The
    government insists that a rational jury could conclude from the
    evidence that Fabian, the company's chief salesman, participated
    in introducing Stratus -- which the jury otherwise concluded was
    a misbranded and adulterated device -- into interstate commerce.
    We agree with the government's assessment, starting with
    how to properly characterize the actus reus of the crime.           Section
    331(a), upon which Fabian's conviction stands, prohibits "[t]he
    introduction or delivery for introduction into interstate commerce
    of any . . . device . . . that is adulterated or misbranded."              
    21 U.S.C. § 331
    (a).     Plainly enough, the prohibited act under the
    statute is causing a misbranded or adulterated device to be
    introduced into interstate commerce.          To be sure, the fact that
    the device is misbranded or adulterated (and that the article is
    a device to begin with) is a separate element of the offense, which
    the government must prove to carry a conviction.         But it does not
    - 73 -
    follow -- and nothing in § 331(a) suggests -- that the government
    must prove that the defendant caused it to be misbranded.
    Our recent analysis in United States v. Stepanets, 
    989 F.3d 88
    , 95 (1st Cir. 2021), is instructive.                     As relevant here,
    Stepanets concerned an appeal from a conviction under 
    21 U.S.C. § 331
    (a)    for     delivering       a    misbranded      drug    into   interstate
    commerce.        The government's theory on misbranding turned on 
    21 U.S.C. § 353
    (b)(1), which provides that "the act of dispensing a
    drug" absent a proper prescription "shall be deemed to be an act
    which results in the drug being misbranded while held for sale."
    The defendant urged us to overturn the conviction on the ground
    that the record contained no evidence that she, personally, had
    dispensed the drug improperly, thereby misbranding it.                     While we
    ultimately found it unnecessary to reach that issue, we expressed
    doubt that the statutory scheme required such a showing.                          See
    Stepanets, 989 F.3d at 95.               After all, the prohibited act under
    the statute is "causing . . . [t]he introduction or delivery for
    introduction into interstate commerce of any" such drug. 
    21 U.S.C. § 331
    (a). Section 353(b)(1) explained why the drug was misbranded,
    but, as we pointed out, nothing in § 331, under which Stepanets
    was   charged,     required    the       government    to   prove   that    she   had
    personally caused the drug to become misbranded, so long as she
    caused     the    misbranded     drug       to    enter     interstate     commerce.
    Stepanets, 989 F.3d at 95.
    - 74 -
    Likewise, here, Fabian was convicted under § 331(a) for
    causing an adulterated or misbranded device to be introduced into
    interstate commerce.     The government's theory on adulteration or
    misbranding turns on different FDCA provisions from those at issue
    in Stepanets, but our analysis there is equally applicable here.
    That is, the jury in this case needed to determine that the device
    was adulterated or misbranded (or both), but it did not need to
    conclude that Fabian caused the adulteration or misbranding.               As
    we observed in Stepanets, § 331(a) speaks of no such requirement,
    but only of "causing . . . [t]he introduction or delivery for
    introduction          into          interstate           commerce          of
    any . . . device . . . that is adulterated or misbranded."
    Accordingly,       we   reject    Fabian's   assertion    that   the
    government needed to prove that he participated in the Stratus
    § 510(k) filings.28     Evidence that Fabian caused the device to
    28 Fabian claims that the district court's order denying
    appellants' motion for acquittal characterized the actus reus as
    he does on appeal. That claim is mistaken. In its order, the
    court stated that the actus reus for marketing a misbranded device
    was "Defendants' failure to submit a premarket notification for
    the intended use" of the drug. Facteau, 
    2020 WL 5517573
    , at *14
    (emphasis added). In other words, the district court described
    the actus reus as marketing a device that lacked the proper
    regulatory clearance, which rendered it misbranded and adulterated
    under the FDCA.      See 
    21 U.S.C.A. § 352
    (o).      For both the
    adulteration and misbranding counts, the court's instructions on
    the second element of the crimes further made clear the actus reus
    by appellants that the jury needed to find: "caus[ing]" an
    adulterated or misbranded device "to be introduced into interstate
    commerce."
    - 75 -
    enter into interstate commerce was sufficient -- assuming, as the
    jury   found    here,      that   the    device    was   indeed      adulterated    or
    misbranded.
    Fabian does not specifically challenge the sufficiency
    of the government's evidence to establish that he caused Stratus
    to enter interstate commerce, nor could he.                 As we have discussed,
    the record is replete with evidence showing that Fabian, as
    Acclarent's vice president of sales, had a hand in marketing
    Stratus   and    thereby     caused      it   to   enter    interstate      commerce.
    Moreover, even in the absence of evidence specifically tying Fabian
    to the strategy of marketing Stratus to deliver Kenalog, the jury's
    verdict would stand under Dotterweich, 
    320 U.S. 277
    , and Park, 
    421 U.S. 658
    .      These cases -- both concerning violations of § 331 of
    the FDCA -- stand for the proposition that the statute is violated
    by anyone who has "a responsible share in the furtherance of the
    transaction which the statute outlaws, namely, to put into the
    stream of interstate commerce adulterated or misbranded drugs."
    Dotterweich, 
    320 U.S. at 284
    .             Thus, the government's evidence is
    sufficient to sustain a conviction under § 331 of an individual
    who    "had,    by   reason       of    his   position      in   the    corporation,
    responsibility       and    authority     either    to     prevent     in   the   first
    instance, or promptly to correct, the violation complained of, and
    [who] failed to do so," even absent direct evidence tying the
    defendant to the act.             Park, 
    421 U.S. at 673-74
    .             Charged with
    - 76 -
    spearheading Acclarent's sales and marketing strategy for Stratus,
    Fabian was well-situated to prevent or correct the marketing of
    adulterated and misbranded Stratus, and it was reasonable for the
    jury to find him culpable for failing to do so.
    2. Excessive Fines Clause
    Fabian challenges the $500,000 fine the district court
    imposed on him.   He asserts that this fine, which is 2.5 times the
    recommended   guidelines   amount   but   well   within   the   statutory
    maximum, is excessive in violation of the Eighth Amendment.           The
    government counters that Fabian has waived any such argument, and,
    regardless, his challenge fails the test laid out in United States
    v. Bajakajian, 
    524 U.S. 321
     (1998), and our cases applying it.
    The government's argument for waiver is not without
    merit.   Not only did Fabian fail to lodge an Eighth Amendment
    objection to the fine at sentencing, but he also acknowledged that
    the court could depart from the guidelines up to the statutory
    maximum. Nonetheless, we choose to deem the Eighth Amendment claim
    forfeited rather than waived and, as in similar cases, we will
    review the district court's judgment for     plain error.       See, e.g.,
    United States v. Sepúlveda–Hernández, 
    752 F.3d 22
    , 36 (1st Cir.
    2014); United States v. Aguasvivas-Castillo, 
    668 F.3d 7
    , 16 (1st
    Cir. 2012); United States v. Beras, 
    183 F.3d 22
    , 28 (1st Cir.
    1999).   See also Fed. R. Crim. P. 52(b) ("A plain error that
    affects substantial rights may be considered even though it was
    - 77 -
    not brought to the court's attention.").                   Fabian therefore "must
    show '(1) that an error occurred (2) which was clear or obvious
    and which not only (3) affected [his] substantial rights, but also
    (4) seriously     impaired        the    fairness,        integrity,     or    public
    reputation of judicial proceedings.'"                   Nieves-Meléndez, 58 F.4th
    at 579 (quoting Merced-García, 24 F.4th at 79-80).29
    Fabian has not made that showing.                   For a fine to be
    excessive    under     the   Eighth      Amendment,        it   must   be     "grossly
    disproportional      to    the    gravity   of     the     defendant's      offense."
    Bajakajian, 
    524 U.S. at 337
    .             We have distilled from the Supreme
    Court's     guidance      three   factors        that    courts   must      consider:
    "(1) whether the defendant falls into the class of persons at whom
    the criminal statute was principally directed; (2) other penalties
    authorized by the legislature (or the Sentencing Commission); and
    (3) the harm caused by the defendant."              United States v. Heldeman,
    
    402 F.3d 220
    , 223 (1st Cir. 2005) (citing Bajakajian, 
    524 U.S. at
    29 The government further contends that Fabian waived plain
    error review by failing to apply this four-factor test in his
    opening brief. While that is true, his arguments make apparent
    his theory of the district court's plain error, and he did squarely
    address the plain error factors in his reply brief. See United
    States v. Serrano-Delgado, 
    29 F.4th 16
    , 27 (1st Cir. 2022) (citing
    United States v. Pabon, 
    819 F.3d 26
    , 33–34 (1st Cir. 2016))
    ("[P]lain error review is waived if its four-part test is not
    argued at least in reply."). Moreover, "'[w]here a defendant's
    claim would fail even if reviewed for plain error, we have often'
    simply proceeded to the merits."        Grullon, 996 F.3d at 32
    (alteration in original) (quoting United States v. Brake, 
    904 F.3d 97
    , 99 (1st Cir. 2018)). As we explain, Fabian's Eighth Amendment
    claim fails under plain error review.
    - 78 -
    337-40).30    Nothing from this guidance suggests that the fine the
    district court imposed was in error.
    First,     as     an   executive     of   a      medical   device
    company -- and        one    specifically    tasked    with    marketing   its
    products -- Fabian falls squarely within "the class of persons at
    whom    [§ 331(a)]     [is]   principally     directed."      Id.31     Second,
    comparison to the "other penalties authorized by the legislature
    (or the Sentencing Commission)" shows that the fine the district
    court imposed is not excessive.             Id.   Notably, Fabian's fine is
    only half of the maximum fine authorized by the statute.                See 
    18 U.S.C. § 3571
    (b)(5). Indeed, Facteau, Fabian's co-defendant, was
    Bajakajian and Heldeman both concerned forfeitures rather
    30
    than literal fines like the one at issue in this case. However,
    both cases considered those forfeitures to be fines within the
    meaning of the Excessive Fines Clause. See Bajakajian, 
    524 U.S. at 328
     ("Forfeitures -- payments in kind -- are thus 'fines' if
    they constitute punishment for an offense.").        Hence, the
    principles announced in Bajakajian and distilled in Heldeman are
    equally relevant when considering actual fines rather than
    forfeitures.
    Fabian suggests, without citation, that the first Heldeman
    31
    factor is relevant only to cases involving forfeitures and
    therefore does not apply to the fine here. We do not agree. In
    Bajakajian, the Supreme Court considered whether the defendant
    fell within the class of people at whom the statute was directed
    not because the penalty at issue was a forfeiture but to determine
    if the penalty corresponded to the defendant's conduct. In that
    case, the statute was "principally designed" to stop the activity
    of "money launderer[s], drug trafficker[s], [and] tax evader[s],"
    but the defendant was none of these things -- he was carrying the
    forfeited cash to pay off a lawful debt. Bajakajian, 
    524 U.S. at 338
    . By contrast, § 331(a) is principally directed at those, like
    Fabian, who sell medical devices (among other products covered by
    the FDCA).
    - 79 -
    convicted of the same ten counts as Fabian but received the
    statutory maximum fine of $1 million.     Where a fine falls below
    the statutory maximum, we have suggested that "a defendant who
    purposes to challenge its constitutionality faces an especially
    steep uphill climb."   Sepúlveda–Hernández, 
    752 F.3d at 37
    .
    Fabian emphasizes that his fine is more than twice the
    maximum amount stated in the sentencing guidelines, which at the
    time of Fabian's offense was $200,000.   See U.S.S.G. § 5E1.2(c)(3)
    (2014) (maximum fine of $20,000 per count for level 10 offenses).
    True, we have inferred from Bajakajian that "the maximum penalties
    provided under the Guidelines should be given greater weight than
    the statute because the Guidelines take into consideration the
    culpability of the individual defendant."    Beras, 
    183 F.3d at
    29
    n.5 (citing Bajakajian, 
    524 U.S. at
    339 n.14).    But that caution
    does not mean that any fine exceeding the Guidelines, yet within
    the statutory maximum, becomes per se unconstitutional.   In United
    States v. Carpenter, for example, we observed that the Guidelines
    were calibrated to the "gain or loss resulting from the offense,"
    sanctioning an upward departure when necessary to achieve that
    aim.   
    941 F.3d 1
    , 11 n.8 (1st Cir. 2019) (quoting U.S.S.G. § 5E1.2
    cmt. n.4).     There, we ultimately upheld a forfeiture of $14
    million, which dwarfed the maximum guideline sentence of $100,000.
    Here, the district court reasoned that Fabian's crime warranted a
    hefty financial penalty because "[t]his was a crime about money"
    - 80 -
    and "in the corporate environment in which we live," the "best
    way" to "accomplish general deterrence" is by "financial penalty."
    The district court thus justified its decision to exceed the
    Guidelines with a thoughtful explanation that reveals no error.
    Finally, while the record does not show injury to others
    or financial harm, damage to the government's regulatory interests
    is also an important consideration.                 See, e.g., United States v.
    Jose, 
    499 F.3d 105
    , 112 (1st Cir. 2007) (choosing to "adhere to
    Congress's     view    that    defendant's         violation    of    the    bulk   cash
    smuggling statute constitutes a significant harm," without noting
    any   direct    harm   to     individuals         resulting    from    his   actions);
    Aguasvivas-Castillo,          
    668 F.3d at 17
       (stating      that   harm   from
    defendant's food stamp fraud included "introduc[ing] waste into
    the program," undermining efforts to "reduce opportunities for
    fraud,"   and    subverting         Puerto    Rico's     judgment      about   how   to
    administer its food stamp program).
    Here, the district court noted the regulatory harm of
    Fabian's conduct, remarking:
    I feel [it] is critically important to
    protect . . . the integrity of the regulatory
    process.   . . .  I think that the FDA is
    important. I think that they try very hard to
    do what is a very difficult job, and it is
    important to maintain the integrity of this
    process for them.
    And again as I noted [in Facteau's sentencing
    hearing], particularly in the time of COVID,
    it's become just starkly clear how important
    - 81 -
    it is that the public have confidence in what
    the FDA does.
    The district court's conclusion that these harms to the
    government's regulatory prerogatives warranted serious punishment,
    even in the absence of recorded harm to any individual, is well-
    founded.   After all, the FDCA reflects Congress's longstanding
    view that marketing unadulterated or misbranded medical devices is
    a serious offense, the violation of which endangers public health
    and harms the government's interests in ensuring public confidence
    in the market for products overseen by the FDA.32
    Because we conclude that the district court's sentence
    was not in error, much less plain error, we find that Fabian's
    fine of $500,000 passes muster under the Eighth Amendment.
    III.
    To   briefly   recap   our      holdings,   we   conclude   that
    appellants' convictions did not violate the First Amendment or
    32 See, e.g., POM Wonderful LLC v. Coca-Cola Co., 
    573 U.S. 102
    , 108 (2014) ("The FDCA statutory regime is designed primarily
    to protect the health and safety of the public at large."); Brown
    & Williamson Tobacco Corp., 
    529 U.S. at 133
     ("[O]ne of the Act's
    core objectives is to ensure that any product regulated by the FDA
    is 'safe' and 'effective' for its intended use. . . . This
    essential purpose pervades the FDCA."); In re Zofran (Ondansetron)
    Prod. Liab. Litig., 
    57 F.4th 327
    , 330 (1st Cir. 2023) ("Congress
    enacted the Food, Drug, and Cosmetic Act (FDCA) in 1938 'to bolster
    consumer protection against harmful products.'" (quoting Wyeth v.
    Levine, 
    555 U.S. 555
    , 574 (2009))). See also 
    21 U.S.C. § 393
    (b)(2)
    (defining the FDA's mission as "protect[ing] the public health by
    ensuring that . . . there is reasonable assurance of the safety
    and effectiveness of devices intended for human use").
    - 82 -
    constitutional due process, that the district court's instruction
    to the jury that it may consider evidence of intended use from any
    relevant source was proper, that Fabian's conviction was supported
    by sufficient evidence, and that Fabian's fine did not violate the
    Eighth Amendment.   We therefore affirm appellants' convictions and
    Fabian's fine.
    So ordered.
