    Opinion for the court filed by Circuit Judge GRIFFITH.
    GRIFFITH, Circuit Judge: In this civil enforcement action,
    we must decide whether the appellants—three individuals and
    a related corporate entity—violated federal laws regulating
    the manufacture and labeling of drugs and biological products
    by producing, as part of their medical practice, a substance
    consisting of a mixture of a patient’s stem cells and the
    antibiotic doxycycline. Because we conclude that they did, we
    affirm the district court’s judgment and the permanent
    injunction it entered against appellants.
    I
    A
    This case involves two statutes under which the Food and
    Drug Administration (FDA) regulates the healthcare industry:
    the Federal Food, Drug & Cosmetic Act (FDCA), 
    21 U.S.C. § 301
     et seq., and the Public Health Service Act (PHSA), 
    42 U.S.C. § 201
     et seq. Those statutes promote the safety of
    drugs and biological products, respectively, by setting forth
    detailed requirements for how such substances are to be
    3
    manufactured and labeled. See 
    21 U.S.C. §§ 351
     (FDCA
    manufacturing requirements), 352 (FDCA labeling
    requirements); 
    42 U.S.C. § 262
    (j) (incorporating by reference
    most of the FDCA’s provisions, including its manufacturing
    and labeling requirements, into the PHSA). Drugs and
    biological products not satisfying those requirements are
    deemed “adulterated” or “misbranded,” see 
    21 U.S.C. §§ 351
    ,
    352, 353(b)(4); 
    42 U.S.C. § 262
    (j), and doing any act that
    causes a drug or biological product to be adulterated or
    misbranded is a violation of federal law, 
    21 U.S.C. § 331
    (k);
    
    42 U.S.C. § 262
    (j). The FDA may seek an injunction to
    prohibit such violations. 
    21 U.S.C. § 332
    (a); 
    42 U.S.C. § 262
    (j).
    B
    The substance at issue in this case is produced by
    appellants Dr. Christopher Centeno, Dr. John Schultz,
    Michelle Cheever, and Regenerative Sciences, LLC, as part of
    a medical therapy that they market as the “Cultured Regenexx
    Procedure” (the Procedure). Drs. Centeno and Schultz, who
    practice medicine together at the Centeno-Schultz Clinic in
    Colorado, jointly developed the Procedure to treat patients’
    orthopedic conditions. They are the majority shareholders of
    Regenerative Sciences, which they founded and which, in
    turn, owns the Procedure and licenses it exclusively to the
    Centeno-Schultz Clinic. Michelle Cheever is the laboratory
    director for Regenerative Sciences.
    The Procedure begins with the extraction of a sample of a
    patient’s bone marrow or synovial fluid. From that sample,
    Regenerative Sciences isolates mesenchymal stem cells
    (MSCs), which are capable of differentiating into bone and
    cartilage cells. The MSCs are then placed in a solution to
    culture them—that is, to cause them to divide and proliferate.
    4
    Other substances are sometimes added to the solution that
    affect the MSCs’ differentiation. The culturing process
    determines the growth and biological characteristics of the
    resulting cell population. When the MSCs are sufficiently
    numerous for re-injection, they are combined with
    doxycycline, an antibiotic obtained in interstate commerce
    and used to prevent bacterial contamination of the MSCs. The
    resulting mixture (the Mixture) is injected into the patient
    from whom the stem cell sample was initially taken, at the site
    of the damaged tissue.
    Appellants promote the Procedure as an alternative to
    surgery for various orthopedic conditions and diseases. In
    court filings, they have described the Procedure as a
    “treatment [for] orthopedic injuries and arthritis” and for
    “musculoskeletal and spinal injury.” Their promotional
    materials recommend the Procedure for treatment of
    osteoarthritis, non-healing bone fractures, chronic bulging
    lumbar discs, and soft tissue injuries.
    In August 2010, the government filed this action for a
    permanent injunction against appellants, alleging that the
    Mixture is both a drug and a biological product that is
    adulterated and misbranded in violation of § 331(k) of the
    FDCA and § 262(j) of the PHSA, which incorporates § 331(k)
    by reference. Appellants counterclaimed, asserting that the
    Mixture is not subject to federal regulation and that, even if it
    is, the FDA’s effort to regulate the Mixture is defective under
    both the PHSA and the Administrative Procedure Act (APA),
    
    5 U.S.C. § 706
    (2).
    The district court granted the government’s motion for
    summary judgment and dismissed appellants’ counterclaims,
    holding that they had violated the FDCA and the PHSA.
    United States v. Regenerative Scis., LLC, 
    878 F. Supp. 2d
                                  5
    248, 263 (D.D.C. 2012). Then, finding a “cognizable danger
    of a recurrent violation,” the district court entered a
    permanent injunction prohibiting appellants from committing
    further violations of the FDCA’s adulteration and
    misbranding restrictions. 
    Id. at 262-63
     (internal quotation
    marks omitted). Appellants timely appealed both orders.
    We have jurisdiction to review the district court’s orders
    under 
    28 U.S.C. § 1291
    . We review the grant of summary
    judgment and dismissal of appellants’ counterclaims de novo,
    “drawing all reasonable inferences from the evidence in the
    light most favorable to the nonmoving party,” Geleta v. Gray,
    
    645 F.3d 408
    , 410 (D.C. Cir. 2011), and affirming only if
    “there is no genuine dispute as to any material fact and the
    movant is entitled to judgment as a matter of law,” FED. R.
    CIV. P. 56(a). We review the district court’s entry of a
    permanent injunction for abuse of discretion and its factual
    findings for clear error. United States v. Philip Morris USA
    Inc., 
    566 F.3d 1095
    , 1110 (D.C. Cir. 2009) (per curiam).
    II
    Appellants’ principal argument is that the Mixture is not
    subject to regulation under the FDCA or PHSA because it is
    neither a drug nor a biological product but is, rather, a
    medical procedure. The text of those statutes forecloses this
    argument.
    The FDCA defines a “drug” as any “article[] intended for
    use in the diagnosis, cure, mitigation, treatment, or prevention
    of disease” or “intended to affect the structure or any function
    of the body.” 
    21 U.S.C. § 321
    (g)(1); see also 
    21 C.F.R. § 201.128
     (providing that a drug’s intended use is shown by
    “the objective intent of the persons legally responsible for the
    labeling of [the] drug[],” which “may . . . be shown by
    6
    labeling claims, advertising matter, or oral or written
    statements by such persons or their representatives”). The
    PHSA defines “biological product” in similarly broad terms
    as any “virus, therapeutic serum, toxin, antitoxin, vaccine,
    blood, blood component or derivative . . . or analogous
    product . . . applicable to the prevention, treatment, or cure of
    a disease or condition of human beings.” 
    42 U.S.C. § 262
    (i)(1). Both of these wide-ranging definitions clearly
    apply to the Mixture, an article derived mainly from human
    tissue and intended to treat orthopedic diseases and to affect
    musculoskeletal function. Indeed, appellants do not actually
    dispute that the plain language of the statutes compels this
    conclusion.
    Rather, appellants urge us to construe the FDCA in light
    of purported federalism concerns. 1 But appellants’ concerns
    lack merit. They boil down to the following syllogism: the
    FDCA was not intended to infringe on states’ traditional role
    in regulating the practice of medicine; the Procedure fits
    Colorado’s statutory definition of the “practice of medicine”;
    therefore, the FDA’s regulation of the Procedure exceeds the
    FDA’s authority under the FDCA. This syllogism is flawed
    twice over.
    First, it misapprehends what this case is about.
    Notwithstanding appellants’ attempt to characterize this case
    1
    Because the PHSA simply incorporates the FDCA’s
    substantive provisions by reference, the scope of the FDCA’s
    provisions is determinative of the reach of the PHSA’s provisions
    as well. Thus, the parties’ arguments and our discussion focus on
    the scope and application of the FDCA—keeping in mind that to
    adulterate and misbrand a substance that is both a drug and a
    biological product violates the PHSA as well as the FDCA.
    7
    as an effort by the FDA to “restrict[] the use of an autologous
    stem cell procedure,” 2 Appellants’ Br. 8 (emphasis added),
    the focus of the FDA’s regulation is the Mixture. That is, the
    FDA does not claim that the procedures used to administer the
    Mixture are unsafe; it claims that the Mixture itself is unsafe.
    Appellants’ arguments about the practice-of-medicine
    exemption are therefore wide of the mark.
    Second, appellants are wrong to suggest that the scope of
    the FDCA depends on state-by-state definitions of the
    “practice of medicine.” The FDCA enacts a comprehensive,
    uniform regulatory scheme for the distribution of drugs. The
    scheme’s breadth—and, more specifically, its applicability to
    doctors—is evident in the fact that the FDCA carves out
    certain exceptions from its requirements for doctors who
    manufacture and administer drugs in the course of their
    professional practice. See, e.g., 
    21 U.S.C. § 360
    (g)(2)
    (exempting licensed healthcare practitioners engaged in
    certain activities from the FDCA’s registration requirements);
    
    id.
     § 374(a)(2)(B) (narrowing the FDA’s ability to review the
    records of licensed healthcare practitioners “who
    manufacture, prepare, propagate, compound, or process drugs
    . . . solely for use in the course of their professional practice”).
    Those exceptions would be unnecessary if the FDCA did not
    otherwise regulate the distribution of drugs by licensed
    physicians. See United States v. Evers, 
    643 F.2d 1043
    , 1048
    (5th Cir. 1981) (“[W]hile the [FDCA] was not intended to
    regulate the practice of medicine, it was obviously intended to
    control the availability of drugs for prescribing by
    physicians.”). Appellants’ construction of the FDCA, by
    contrast, would allow states to gut the FDCA’s regulation of
    2
    An “autologous” stem cell procedure is one in which cells
    are implanted back into the individual from whom they were
    initially taken. See 
    21 C.F.R. § 1271.3
    (a).
    8
    doctors, and thereby create an enormous gap in the FDCA’s
    coverage, by classifying the distribution of drugs by doctors
    as the practice of medicine. Given Congress’s intent that the
    FDCA’s “coverage be as broad as its literal language
    indicates,” United States v. An Article of Drug . . . Bacto-
    Unidisk, 
    394 U.S. 784
    , 798 (1969), such a construction is not
    tenable.
    Equally untenable is appellants’ contention that because
    the Procedure occurs entirely within the state of Colorado, the
    Mixture lacks a sufficient connection to interstate commerce
    to permit federal regulation under the Commerce Clause. It is
    simply impossible to square this argument with the last
    seventy years of Commerce Clause jurisprudence, which, in
    recognition of Congress’s authority to regulate even “purely
    local activities that are part of an economic ‘class of
    activities’ that have a substantial effect on interstate
    commerce,” Gonzales v. Raich, 
    545 U.S. 1
    , 17 (2005), has
    upheld federal laws prohibiting the possession of home-grown
    marijuana intended solely for personal use, 
    id. at 32-33
    , and
    restricting the amount of wheat a farmer can grow purely for
    his farm’s consumption, Wickard v. Filburn, 
    317 U.S. 111
    ,
    128-29 (1942). Here, not only does the Mixture undoubtedly
    have effects on interstate markets for orthopedic care, but it
    actually includes an article shipped in interstate commerce,
    namely, doxycycline. Cf. Raich, 
    545 U.S. at 17
     (noting that
    when Congress concludes that a class of activities
    substantially affects interstate commerce, “the de minimis
    character of individual instances [of those activities] is of no
    consequence” (internal quotation marks omitted)). The
    Commerce Clause poses no obstacle to regulating the Mixture
    under the FDCA.
    Nor can appellants prevail on their argument that even if
    the Mixture may be federally regulated in principle, it falls
    9
    outside the scope of the statute appellants are charged with
    violating, 
    21 U.S.C. § 331
    (k). That provision prohibits “the
    doing of any . . . act with respect to[] a . . . drug . . . if such act
    is done while such [drug] is held for sale . . . after shipment in
    interstate commerce and results in such [drug] being
    adulterated or misbranded.” 
    Id.
     (emphasis added). Appellants
    read § 331(k) to require that the entire Mixture have been
    shipped in interstate commerce. They contend that merely
    using an ingredient that travelled in interstate commerce—
    here, doxycycline—is insufficient to trigger the bar. We
    disagree. Not only does the FDCA define the term “drug” to
    include a drug’s components, but to interpret § 331(k) as
    appellants suggest would severely narrow a statutory scheme
    designed to regulate the safety of drugs at every stage of their
    distribution. See Evers, 
    643 F.2d at 1049
     (explaining that
    § 331 is “designed to prevent misbranding at each stage of the
    distribution process”); id. at 1050 (“Doctors holding drugs for
    use in their practice are clearly one part of the distribution
    process . . . .”). The two circuits to have considered this issue
    have reached the same conclusion. In United States v.
    Dianovin Pharmaceuticals, Inc., which involved a
    pharmaceutical company that used raw vitamin K purchased
    in interstate commerce to manufacture injectable vitamin K,
    the First Circuit held that the company’s “use of components
    shipped in interstate commerce . . . brought their activities
    within § 331(k).” 
    475 F.2d 100
    , 102-03 (1st Cir. 1973); see
    also United States v. Cassaro, Inc., 
    443 F.2d 153
    , 156 (1st
    Cir. 1971) (explaining that, under the Supreme Court’s
    decision in United States v. Sullivan, 
    332 U.S. 689
     (1948),
    “interstate commerce in drugs continue[s] even after the first
    purely intrastate sale”). Similarly, in Baker v. United States,
    the Ninth Circuit held that § 331(k)’s “‘shipment in interstate
    commerce’ requirement is satisfied even when only an
    ingredient is transported interstate.” 
    932 F.2d 813
    , 814 (9th
    Cir. 1991). We therefore hold that, by virtue of its use of
    10
    doxycycline, the Mixture is within the scope of drugs—and,
    by extension, biological products, see 
    42 U.S.C. § 262
    (j)—
    regulated by § 331(k).
    III
    Appellants next advance two arguments why the Mixture
    is exempt from the FDCA’s manufacturing and labeling
    requirements even if it is otherwise subject to federal
    regulation. Each argument fails.
    A
    In addition to regulating biological products directly, the
    PHSA gives the FDA authority to issue regulations to prevent
    the interstate spread of communicable disease. See 
    42 U.S.C. § 264
    (a). Pursuant to that authority, in 2001 the FDA
    promulgated regulations to ensure the safety of human cells,
    tissues, and cellular or tissue-based products (HCT/Ps) used
    for therapeutic purposes. Those regulations, which appear at
    21 C.F.R. part 1271, define HCT/Ps, in relevant part, as
    “articles containing or consisting of human cells or tissues
    that are intended for implantation, transplantation, infusion, or
    transfer into a human recipient.” 
    21 C.F.R. § 1271.3
    (d).
    HCT/Ps may qualify as drugs or biological products, and
    when they do, the FDA generally regulates them accordingly
    under the FDCA, PHSA, and corresponding regulations. See
    
    id.
     § 1271.20; see also Application of Current Statutory
    Authorities to Human Somatic Cell Therapy Products and
    Gene Therapy Products, 
    58 Fed. Reg. 53,248
    , 53,249 (Oct.
    14, 1993) (“Cellular products intended for use as somatic cell
    therapy are biological products subject to regulation pursuant
    to the [PHSA] and also fall within the definition of drugs in
    the [FDCA].”). The Part 1271 Regulations, however, create a
    regulatory exemption from the manufacturing and labeling
    11
    requirements that normally apply to drugs and biological
    products for any HCT/P that is no more than “minimally
    manipulated.” 3 See 
    21 C.F.R. § 1271.10
    (a). “Minimal
    manipulation” of cells means “processing that does not alter
    the relevant biological characteristics.” 
    Id.
     § 1271.3(f)(2).
    Appellants claim this exemption applies to the Mixture, but
    the government offers several reasons why appellants’
    culturing process alters the MSCs’ relevant biological
    characteristics and is therefore more than minimal
    manipulation. As to some of those reasons, such as the
    government’s claim that culturing MSCs alters the genes and
    proteins they express, appellants have created genuine issues
    of fact by submitting expert affidavits arguing that the
    government’s views are based on scientific studies that are
    inapplicable to appellants’ culturing process. But appellants
    give no response to other reasons offered by the government.
    For example, appellants admit that the culturing process is
    designed to “determine the growth and biological
    characteristics of the resulting cell population.” It is also
    undisputed that, in at least some cases, appellants add
    substances to the cell culture that affect the differentiation of
    bone marrow cells.
    These concessions are fatal to appellants’ attempt to
    claim refuge under § 1271.10(a). Given that § 1271.10(a) is
    an exemption from the otherwise applicable provisions of the
    FDCA, appellants ultimately bear the burden of establishing
    that it applies to the Mixture. See United States v. First City
    Nat’l Bank of Houston, 
    386 U.S. 361
    , 366 (1967) (stating the
    3
    To qualify for this regulatory exemption, an HCT/P must
    meet several other criteria as well, pertaining to its method of
    manufacture and intended use. See 
    21 C.F.R. § 1271.10
    (a). The
    government does not claim, however, that the Mixture fails to meet
    any of those additional criteria.
    12
    “general rule” of statutory construction that the party who
    “claims the benefits of an exception to the prohibition of a
    statute” carries the burden of establishing that the exception
    applies); FTC v. Morton Salt Co., 
    334 U.S. 37
    , 44-45 (1948).
    Because appellants concede that culturing MSCs affects their
    characteristics and offer no evidence that those effects
    constitute only minimal manipulation, they fail to carry that
    burden as a matter of law.
    We emphasize that we reach this conclusion based on the
    evidence in the record, and not merely by deferring to the
    FDA’s statement in the preamble to the Part 1271 Regulations
    that expansion of MSCs in culture automatically constitutes
    more than minimal manipulation. See Human Cells, Tissues,
    and Cellular and Tissue-Based Products; Establishment
    Registration and Listing, 
    66 Fed. Reg. 5447
    , 5457 (Jan. 19,
    2001) (“We do not agree that the expansion of mesenchymal
    cells in culture . . . [is] minimal manipulation.”). Appellants
    devote considerable energy to challenging that statement as an
    invalid legislative rule that the FDA now seeks to enforce
    against them. That is, they claim that the FDA seeks to give
    legal effect to a statement that was not promulgated through
    formal rule-making procedures, which the APA forbids. Our
    decision, however, is based on, and gives effect to, the Part
    1271 Regulations, not the preamble. Appellants’ procedural
    challenge to the preamble is therefore irrelevant.
    Surprisingly, appellants also challenge the Part 1271
    Regulations as ultra vires if applied to autologous stem cell
    procedures because, they argue, such procedures do not carry
    the risk of spreading communicable disease and thus are not
    subject to regulation under 
    42 U.S.C. § 264
    . It is unclear what
    appellants hope to achieve with this claim; to prevail would
    only mean invalidating the very exemption from the FDCA in
    which they hope to take refuge. In any case, the FDA’s
    13
    findings, which appellants do not challenge, undercut
    appellants’ argument. In promulgating the Part 1271
    Regulations, the FDA noted that any procedure involving
    HCT/Ps risks spreading disease through, for example,
    “[e]rrors in labeling, mixups of testing records, failure to
    adequately clean work areas, and faulty packaging.” Current
    Good Tissue Practice for Human Cell, Tissue, and Cellular
    and Tissue-Based Product Establishments; Inspection and
    Enforcement, 
    69 Fed. Reg. 68,612
    , 68,613 (Nov. 24, 2004).
    Indeed, Regenerative Sciences’ own standard operating
    procedure takes a similar view, recognizing the risk of
    “[c]ontamination” as a “major problem in tissue culture” and
    stressing the need for “good tissue practices” to “prevent the
    introduction, transmission, or spread of communicable
    diseases.” Appellants thus offer no basis to conclude that the
    Part 1271 Regulations exceed the FDA’s authority to issue
    regulations “to prevent the introduction, transmission, or
    spread of communicable diseases” between states. 
    42 U.S.C. § 264
    (a).
    B
    Alternatively, appellants contend that the Mixture is
    exempt from the FDCA’s manufacturing and labeling
    requirements because it is a compounded drug. See 21 U.S.C.
    § 353a(a). A compounded drug must be produced using
    certain types of “bulk drug substances,” one of which is “bulk
    drug substances . . . that . . . are components of drugs
    approved by the [government].” Id. § 353a(b)(1)(A).
    Appellants assert that the Mixture meets this definition
    because cultured MSCs are a component of the FDA-
    approved drug Carticel. But even if that were the case—and
    the affidavits appellants cite only suggest that it might be—it
    would not be enough to bring the Mixture within § 353a. To
    qualify as a “bulk drug substance,” an item must be
    14
    “represented for use in a drug,” 
    21 C.F.R. § 207.3
    (a)(4), and
    appellants point to no evidence in the record even suggesting
    that MSCs are held out for use in Carticel, or any other drug
    for that matter. Appellants therefore fail to establish that the
    Mixture is exempt from the FDCA’s manufacturing and
    labeling requirements, and we proceed to consider whether
    the Mixture violated them.
    IV
    A
    The FDCA provides that a drug “shall be deemed to be
    adulterated . . . if . . . the methods used in, or the facilities or
    controls used for, its manufacture, processing, packing, or
    holding do not conform to or are not operated or administered
    in conformity with current good manufacturing practice.” 
    21 U.S.C. § 351
    (a) (emphasis added). The FDA has established
    the specific elements of current good manufacturing practice
    at 21 C.F.R. parts 210-211. Here, it is undisputed that
    appellants’ facilities, methods, and controls for processing the
    Mixture violated federal manufacturing standards in
    numerous respects. Therefore, the Mixture is per se
    adulterated, regardless of any other safety protocols appellants
    happen to use. See John D. Copanos & Sons, Inc. v. FDA, 
    854 F.2d 510
    , 514 (D.C. Cir. 1988) (“Drugs produced in violation
    of [federal manufacturing] regulations are deemed to be
    adulterated without the agency having to show that they are
    actually contaminated.”).
    B
    The FDCA also provides that a drug “shall be deemed to
    be misbranded” if its label omits certain information. As
    relevant here, the FDCA requires that a drug’s label provide
    15
    “adequate directions for use,” 
    21 U.S.C. § 352
    (f)(1), and, in
    the case of prescription drugs, bear the symbol “Rx only,” 
    id.
    § 353(b)(4)(A). Appellants admit that the Mixture’s labeling
    satisfies neither of these requirements. 4
    Appellants nevertheless argue that it is inappropriate to
    hold them liable for not providing adequate directions because
    they produced the Mixture only for their own use. This
    argument, however, misunderstands how the FDCA’s labeling
    scheme applies to prescription drugs. To satisfy § 352(f)’s
    requirement of providing “adequate directions for use,” a
    drug’s label must provide “directions under which the layman
    can use a drug safely and for the purposes for which it is
    intended.” 
    21 C.F.R. § 201.5
     (emphasis added). A
    prescription drug, however, is by definition “not safe for use
    except under the supervision of a practitioner licensed by law
    to administer such drug.” 
    21 U.S.C. § 353
    (b)(1)(A) (emphasis
    added). It is thus impossible to provide “adequate directions
    for use” for prescription drugs. As the Seventh Circuit has
    observed, this means that prescription drugs are
    “presumptively misbranded.” United States v. An Article of
    Device, 
    731 F.2d 1253
    , 1261 (7th Cir. 1984); see United
    States v. Articles of Drug, 
    625 F.2d 665
    , 673 (5th Cir. 1980)
    (holding that § 352(f)(1) requires a drug’s labeling to “contain
    adequate directions for a consumer to engage in self-
    medication” and noting that a “prescription drug by definition
    . . . is unsuitable for self-medication”). A prescription drug
    can avoid being actually misbranded only by qualifying for
    4
    The Mixture’s label would have to bear the symbol “Rx
    only” even if the Mixture were a compounded drug. See 21 U.S.C.
    § 353a(a) (exempting compounded drugs from the labeling
    requirements of § 352(f)(1) but not § 353(b)(4)). Thus, even if we
    were to accept appellants’ compounding argument, the Mixture still
    would be misbranded. See id. § 353(b)(4).
    16
    either of two exemptions from § 352(f): the statutory
    exemption, which applies when licensed practitioners
    distribute drugs to patients via prescriptions, see 
    21 U.S.C. § 353
    (b)(2), or the regulatory exemption, which applies to
    prescription drugs at any stage of distribution, see 
    21 C.F.R. § 201.100
    ; Articles of Drug, 
    625 F.2d at 673
    . A prescription
    drug’s label must contain specific information in order for
    either exemption to apply. If the label does not contain every
    piece of required information, the prescription drug will
    remain subject to the impossible mandate of § 352(f) and will
    be misbranded.
    Here, there is no doubt that the Mixture qualifies as a
    prescription drug. Before the Mixture can be injected into a
    patient, a physician must review the cultured MSCs to ensure
    that there are no visible signs of bacterial contamination or
    genetic mutation. Then, if the MSCs are safe, appellants inject
    the Mixture using sophisticated imaging devices to ensure that
    it reaches the right spot on a patient’s bone or tissue so that it
    has the intended therapeutic effect. Because the Mixture can
    be safely administered only under a physician’s supervision,
    the question for us is whether the Mixture qualifies for either
    § 352(f) exemption. The answer is clear. Both exemptions
    require that the label bear the symbol “Rx only,” see 
    21 U.S.C. § 353
    (b)(4)(A); 
    21 C.F.R. § 201
    .l00(b)(1), and it is
    undisputed that the Mixture’s label does not. Because its label
    fails to provide the minimum information necessary to qualify
    for either exemption from § 352(f), the Mixture is
    misbranded.
    In reaching this conclusion, we reject appellants’ broad
    reading of United States v. Evers, in which the Fifth Circuit
    held that a doctor was not liable for violating § 352(f)(1) by
    advertising his off-label use of a prescription drug without
    providing adequate directions for that use. See Evers, 643
    17
    F.2d at 1053-54. Appellants read Evers for the proposition
    that doctors need not comply with the FDCA’s labeling
    requirements when they prescribe drugs only within their own
    practices. But Evers cannot bear the weight of this
    interpretation, which is inconsistent with the fact that the
    FDCA does not exempt doctors in such a categorical manner.
    As the Fifth Circuit made clear, the “object of the
    government’s case” in Evers was not the off-label
    “prescription” of the drug at issue, but rather the “promotion
    and advertising” of such off-label use. Id. at 1049 (emphases
    added). Evers thus differs from this case in two important
    ways: the drug at issue in Evers was FDA approved, and the
    FDA did not question Evers’s right to prescribe that drug to
    his patients. Neither of those circumstances is present here.
    The FDA has not approved the Mixture as safe for any use
    and hence challenges appellants’ right to prescribe the
    Mixture at all. We will not broaden Evers to vitiate the
    FDCA’s labeling requirements in these circumstances. The
    strict exemption criteria presumably reflect the judgment of
    both Congress and the FDA about the minimum information
    necessary to safely distribute prescription drugs. Because
    appellants did not meet those criteria, they misbranded their
    drug.
    V
    Having found that the government is entitled to summary
    judgment that appellants adulterated and misbranded the
    Mixture, we review the district court’s entry of a permanent
    injunction. Appellants attack the injunction on two fronts.
    They contend that in entering the injunction, the district court
    failed to make the necessary findings and that, in any event,
    the facts do not warrant injunctive relief.
    18
    The FDCA gives courts jurisdiction to enjoin violations
    of 
    21 U.S.C. § 331
    (k). See 
    21 U.S.C. § 332
    (a). To obtain
    injunctive relief, the government “must demonstrate a
    ‘reasonable likelihood of further violation[s] in the future.’”
    United States v. Philip Morris USA Inc., 
    566 F.3d 1095
    , 1132
    (D.C. Cir. 2009) (per curiam) (quoting SEC v. Savoy Indus.,
    Inc., 
    587 F.2d 1149
    , 1168 (D.C. Cir. 1978)) (alteration in
    original). A district court should consider three factors in
    determining whether a reasonable likelihood exists:
    “‘[1] whether a defendant’s violation was isolated or part of a
    pattern, [2] whether the violation was flagrant and deliberate
    or merely technical in nature, and [3] whether the defendant’s
    business will present opportunities to violate the law in the
    future.’” 
    Id.
     (quoting SEC v. First City Fin. Corp., 
    890 F.2d 1215
    , 1228 (D.C. Cir. 1989)).
    Appellants argue that the district court failed to make
    findings regarding these three factors. Though it is true that
    the district court did not explicitly list the factors, there can be
    no serious dispute that its factual findings implicate them. In
    justifying the injunction, the district court stated:
    [The] FDA notified [appellants] that their RegenexxTM
    Procedure may be in violation of the [FDCA]. It then
    twice inspected [appellants’] laboratories and found a
    number of [current good manufacturing practice]
    violations. [Appellants] maintained that the FDA
    could not regulate their cell product and did not bring
    their processes into compliance with [current good
    manufacturing practice]. Although [appellants] agreed
    to stop using their RegenexxTM Procedure during the
    pendency of this lawsuit, there remains a “cognizable
    danger of recurrent violation.”
    19
    Regenerative Scis., 878 F. Supp. 2d at 262-63. These findings
    speak to the existence of each relevant factor. The fact that the
    FDA found violations on two separate occasions and that
    appellants refused to take corrective action even after multiple
    FDA notices suggests a pattern of deliberate, even flagrant
    violations. And, of course, these violations were inextricably
    linked to the operation of appellants’ business.
    Even so, appellants maintain that the district court abused
    its discretion. They insist that they have shown “the utmost
    respect for the judicial system” by discontinuing use of the
    Procedure during the pendency of this litigation and that the
    Procedure employed robust safety protocols, albeit not those
    federal regulations required. These facts, however, do not
    establish an abuse of discretion. That appellants suspended
    use of the Procedure does not in itself preclude injunctive
    relief. See United States v. Article of Drug Designated B-
    Complex Cholinos Capsules, 
    362 F.2d 923
    , 928 (3d Cir.
    1966) (“It is well settled that the cessation of activities, either
    before or after suit is begun, does not in itself bar issuance of
    the injunction.”). Furthermore, appellants have admitted to
    over a dozen violations of federal manufacturing regulations,
    and evidence in the record supports the serious nature of those
    violations. Appellants also admit that they did not improve
    their manufacturing process even after receiving FDA
    warnings. Such conduct is sufficient to warrant the permanent
    injunction.
    VI
    For the foregoing reasons, we affirm the district court’s
    orders granting summary judgment to the government,
    dismissing appellants’ counterclaims, and permanently
    enjoining appellants from committing future violations of the
    FDCA’s manufacturing and labeling provisions.
