    PER CURIAM.1
    Several prisoners sentenced to death in Missouri appeal the district court’s2
    dismissal of their complaint challenging the lethal-injection protocol of the Missouri
    Department of Corrections. The prisoners sued state officials who are charged with
    planning, supervising, and carrying out executions, and two independent contractors
    who allegedly have prescribed, produced, or tested the compounded pentobarbital
    used in the State’s current lethal-injection protocol. They sought a declaratory
    judgment that the lethal-injection protocol violates the Constitution of the United
    States, the Missouri Constitution, several provisions of state law, and Missouri
    common law, and an injunction that prevents the defendants from executing them in
    accordance with the protocol.

    The Honorable Beth Phillips, United States District Judge for the Western
    District of Missouri.
    -2-
    I.
    This litigation commenced in 2012 when the prisoners challenged what was
    then a new lethal-injection protocol. In prior years, Missouri’s lethal-injection
    protocol involved the administration of three drugs: “[S]odium thiopental to
    anesthetize the prisoner and render him unconscious, pancuronium bromide to
    paralyze him and stop his breathing, and potassium chloride to stop the prisoner’s
    heart.” Ringo v. Lombardi, 
    677 F.3d 793
    , 795 (8th Cir. 2012). In May 2012, after
    sodium thiopental became unavailable, the State revised its protocol to use a single
    drug—propofol—as the lethal agent.
    In June 2012, the prisoners sued in state court to challenge the new protocol.
    State officials removed the case to federal court and promptly moved to dismiss the
    petition for failure to state a claim. The district court denied the motion in part and
    granted it in part, ruling as relevant here that the plaintiffs had adequately pleaded that
    the protocol presented a risk of harm that violated the Eighth Amendment and that the
    prisoners were not required to plead a reasonable alternative method of execution to
    the use of propofol. The court also ruled that the allegedly higher risk of pain posed
    by the protocol, compared to the State’s prior methods of execution, sufficed to state
    a claim of unconstitutional ex post facto punishment.
    In October 2013, the State informed the district court that it had revised its
    protocol to use pentobarbital, rather than propofol, as the lethal agent. In late 2013,
    after a discovery dispute, the district court ordered the State to disclose to counsel for
    the prisoners the identities of the physician who prescribes the pentobarbital used in
    Missouri executions, the pharmacist who compounds it, and the laboratory that tests
    the compounded drug. In re Lombardi, 
    741 F.3d 888
    , 892 (8th Cir.) (en banc), reh’g
    denied, 
    741 F.3d 903
    (8th Cir.), cert. denied, 
    134 S. Ct. 1790
    (2014). This court
    issued a writ of mandamus vacating the district court’s order requiring disclosure. 
    Id. -3- at
    897. We determined that the complaint then pending failed to state any claim to
    which the identities of those parties was relevant. 
    Id. at 895-97.
    In February 2014, the plaintiffs filed a second amended complaint. That
    complaint alleges ten separate claims, seven of which are at issue in this appeal: (1)
    that the State’s use of compounded pentobarbital constitutes cruel and unusual
    punishment, in violation of the United States Constitution; (2) that the defendants are
    deliberately indifferent to the plaintiffs’ medical need for their executions not to inflict
    gratuitous pain; (3) that the State’s use of compounded pentobarbital creates a
    significant risk of increased punishment over previous methods and accordingly
    amounts to ex post facto punishment, in violation of the United States Constitution;
    (4) that the defendants have deprived them of due process under the United States
    Constitution by not providing timely and adequate notice of the lethal injection
    methods; (5) that the defendants have deprived them of equal protection under the
    United States Constitution by deviating from the execution protocol in certain
    instances; (6) that the defendants have violated their First Amendment rights under the
    United States Constitution by refusing to disclose the identities of the pharmacy that
    compounds the pentobarbital and its suppliers; and (7) that the defendants have
    violated a number of federal laws by soliciting and using the compounded
    pentobarbital in executions, all allegedly reviewable under Missouri’s Administrative
    Procedure Act, Mo. Rev. Stat. § 536.150.
    In May 2014, the district court granted the State’s motion to dismiss the
    complaint. The court dismissed all claims except for that alleging “cruel and unusual
    punishment” in violation of the Eighth Amendment and its Missouri constitutional
    analog. As for the remaining claim, the court ruled that the prisoners’ concession that
    “other methods of lethal injection . . . would be constitutional” did not suffice to state
    a claim under the Eighth Amendment. But the court allowed the prisoners seven days
    to amend the claim and address that deficiency by presenting “factual allegations
    permitting the Court to determine whether the alleged alternative method [of
    -4-
    execution] is reasonably available and less likely to create a substantial risk of harm.”
    The prisoners responded that they did not intend to plead an alternative method of
    execution, because they believed the law did not require them to do so. In light of that
    response, the district court dismissed the remaining claim and entered a final
    judgment. This appeal followed.
    II.
    The prisoners’ lead argument on appeal is that they stated a claim under the
    Eighth Amendment that Missouri’s lethal-injection protocol violates the prohibition
    on cruel and unusual punishment.3 As in Lombardi, our analysis must begin with a
    basic proposition: “[C]apital punishment is constitutional. It necessarily follows that
    there must be a means of carrying it out.” Baze v. Rees, 
    553 U.S. 35
    , 47 (2008)
    (plurality opinion) (internal citation omitted). Any allegation that all methods of
    execution are unconstitutional, therefore, does not state a plausible claim under the
    Eighth Amendment. 
    Lombardi, 741 F.3d at 895
    .
    Baze addressed an Eighth Amendment challenge to a lethal-injection protocol,
    and our opinion in Lombardi summarized the rule of Baze as follows:
    Where, as here, there is no assertion that the State acts purposefully to
    inflict unnecessary pain in the execution process, the Supreme Court
    recognized only a limited right under the Eighth Amendment to require
    a State to change from one feasible method of execution to another. The
    controlling opinion of the Chief Justice in Baze provides that if a State
    refuses to adopt a readily available alternative method of execution that
    would significantly reduce a substantial risk of severe pain, then “a
    State’s refusal to change its method can be viewed as ‘cruel and unusual’
    under the Eighth 
    Amendment.” 553 U.S. at 52
    (plurality opinion)
    3
    The prisoners do not develop an argument on appeal concerning the dismissal
    of their claim alleging cruel and unusual punishment under the Missouri Constitution.
    -5-
    (emphasis added). In sum: “A stay of execution may not be granted on
    grounds such as those asserted here unless the condemned prisoner
    establishes that the State’s lethal injection protocol creates a
    demonstrated risk of severe pain. He must show that the risk is
    substantial when compared to the known and available alternatives.” 
    Id. at 61
    (emphasis 
    added). 741 F.3d at 895-96
    .
    The district court, relying on Lombardi, concluded that the second amended
    complaint adequately alleged that the protocol creates a substantial risk of severe pain.
    The court ruled, however, that the prisoners failed to allege sufficiently the second
    essential element of an Eighth Amendment claim—i.e., that there exists a feasible
    alternative method of execution that would substantially reduce the risk of harm.
    Although the prisoners conceded in the second amended complaint that “other
    methods of lethal injection the Department could choose would be constitutional,” the
    court reasoned that this “naked assertion” was insufficient to allege that an alternative
    method is reasonably available and less likely to create a substantial risk of harm.
    To state a claim under the Federal Rules of Civil Procedure, a complaint must
    contain “a short and plain statement of the claim showing that the pleader is entitled
    to relief.” Fed. R. Civ. P. 8(a)(2). “To survive a motion to dismiss, a complaint must
    contain sufficient factual matter, accepted as true, to ‘state a claim to relief that is
    plausible on its face.’” Ashcroft v. Iqbal, 
    556 U.S. 662
    , 678 (2009) (quoting Bell Atl.
    Corp. v. Twombly, 
    550 U.S. 544
    , 570 (2007)). A pleading need not include “detailed
    factual allegations,” but it is not sufficient to tender “naked assertion[s]” that are
    “devoid of further factual enhancement.” 
    Id. (internal quotation
    marks omitted). A
    complaint must do more than allege “labels and conclusions” or “a formulaic
    recitation of the elements of a cause of action.” 
    Id. -6- A.
    We first address whether the second amended complaint adequately alleges that
    Missouri’s lethal-injection protocol creates a substantial risk of severe pain. We
    review a district court’s grant of a motion to dismiss for failure to state a claim under
    Rule 12(b)(6) de novo. United States ex rel. Raynor v. Nat’l Rural Utils. Coop. Fin.,
    Corp., 
    690 F.3d 951
    , 955 (8th Cir. 2012). We assume all facts in the complaint to be
    true, and draw all reasonable inferences in favor of the non-moving party. 
    Id. “[L]egal conclusions”
    and “threadbare recitations of the elements of a cause of
    action supported by mere conclusory statements” are not entitled to a presumption of
    truth when considering the sufficiency of a complaint. 
    Iqbal, 556 U.S. at 678
    . A
    complaint must be plausible on its face and “‘[a] claim has facial plausibility when the
    pleaded factual content allows the court to draw the reasonable inference that the
    defendant is liable for the misconduct alleged.’” Magee v. Trustees of Hamline Univ.,
    Minn., 
    747 F.3d 532
    , 535 (8th Cir. 2014) (quoting 
    Iqbal, 556 U.S. at 678
    ). Making
    a plausibility determination is a “‘context-specific task that requires the reviewing
    court to draw on its judicial experience and common sense.’” 
    Id. (quoting Iqbal,
    556
    U.S. at 679).
    Stating a plausible Eighth Amendment claim in the context of the prisoners’
    attack upon Missouri’s execution protocol first requires the prisoners to plead
    sufficient facts indicating that the protocol creates a “substantial risk of serious harm.”
    See 
    Baze, 553 U.S. at 50
    (“We have explained that to prevail on such a claim there
    must be a ‘substantial risk of serious harm,’ an ‘objectively intolerable risk of harm’
    that prevents prison officials from pleading that they were ‘subjectively blameless for
    purposes of the Eighth Amendment.’” (quoting Farmer v. Brennan, 
    511 U.S. 825
    ,
    842, 846 & n.9 (1994))). Indeed, the prisoners allege the lethal-injection protocol
    creates a substantial risk of serious harm in that it inflicts a “substantial risk of severe
    pain.” See 
    id. at 52.
    However, successfully pleading facts to demonstrate a
    -7-
    substantial risk of severe pain requires the prisoners to plead more than just a
    hypothetical possibility that an execution could go wrong, resulting in severe pain to
    a prisoner. The Eighth Amendment prohibits an “‘objectively intolerable risk’” of
    pain, rather than “simply the possibility of pain.” 
    Id. at 61
    -62 (quoting 
    Farmer, 511 U.S. at 846
    ). The plurality opinion in Baze acknowledged that the nature of
    executions necessarily involves the risk of pain: “Some risk of pain is inherent in any
    method of execution—no matter how humane—if only from the prospect of error in
    following the required procedure.” 
    Id. at 47.
    But “the Constitution does not demand
    the avoidance of all risk of pain in carrying out executions.” 
    Id. Instead, the
    Eighth
    Amendment requires that the prisoners show the intended protocol is “‘sure or very
    likely to cause serious illness and needless suffering.’” 
    Id. at 50
    (quoting Helling v.
    McKinney, 
    509 U.S. 25
    , 33 (1993)).
    Relying on this court’s decision in Lombardi, the district court found the
    prisoners’ second amended complaint adequately alleged that the protocol created a
    substantial risk of severe pain:
    The Eighth Circuit specifically referenced the language used in
    Plaintiffs’ previous complaints regarding the risk and level of pain
    necessary to plead an Eighth Amendment violation, and gave no
    indication such language was insufficient. Based on that fact and
    the case law cited by Plaintiffs, the Court concludes Plaintiffs
    sufficiently plead an Eighth Amendment claim regarding the risk
    and level of pain that the current execution protocol carries.
    R. Doc. 437, at 8. Our decision in Lombardi addressed the pleading requirement of
    a feasible alternative to the current lethal-injection protocol. It did not address the
    sufficiency of the complaint regarding the allegation of a substantial risk of severe
    pain. Because the district court relied upon our decision in Lombardi as the basis for
    finding the prisoners had satisfied this pleading burden, a determination of the
    sufficiency of the prisoners’ complaint regarding the allegation of a substantial risk
    of severe pain now requires a more thorough analysis.
    -8-
    When reviewing the sufficiency of a complaint, we review the complaint itself
    and any exhibits attached to the complaint. Meehan v. United Consumers Club
    Franchising Corp., 
    312 F.3d 909
    , 913 (8th Cir. 2002) (“‘[M]aterials attached to the
    complaint as exhibits may be considered in construing the sufficiency of the
    complaint.’” (quoting Morton v. Becker, 
    793 F.2d 185
    , 187 (8th Cir. 1986))). The
    prisoners filed a second amended complaint with 32 exhibits attached, including
    declarations and affidavits from medical professionals.
    1.
    In the second amended complaint the prisoners rely on analysis from a
    pharmacology expert and an anesthesiologist in alleging that the use of a
    compounding pharmacy to produce the execution drug creates an “objectively
    intolerable risk of pain.” It is alleged that “[c]ompounding pharmacy products do not
    meet the requirements for identity, purity, efficacy, and safety that pharmaceuticals
    produced under FDA regulations must meet.” R. Doc. 338, at 44. The prisoners
    identify four distinct potential risks which they believe could result from the State’s
    use of compounded pentobarbital. First, they allege that the compounded
    pentobarbital could be sub- or super-potent. According to the second amended
    complaint, sub-potent pentobarbital could fail to cause the death of the prisoner,
    leaving him unconscious with a lower rate of respiration, causing irreversible brain
    damage. R. Doc. 338, at Ex. 5. Super-potent pentobarbital could result in suffocation
    and difficulty breathing before losing consciousness. R. Doc. 338, at Ex. 5. Second,
    the prisoners allege that the pentobarbital could easily be contaminated with allergens,
    toxins, bacteria, or fungus. The prisoners allege that the injection of pentobarbital so
    contaminated could cause a painful allergic reaction in the blood. R. Doc. 338, at 45.
    Third, the prisoners allege that foreign particles could contaminate the compounded
    pentobarbital, creating the risk that a prisoner could experience serious pain upon
    injection or could suffer from a pulmonary embolism. R. Doc. 338, at 45. Finally, the
    -9-
    prisoners allege that the drug may not maintain the proper pH,4 potentially resulting
    in numerous complications, most notably severe burning upon injection or a
    pulmonary embolism. R. Doc. 338, at 45. The prisoners also allege that improper
    storage of the pentobarbital and use beyond its expiration date could exacerbate the
    potential for these harms. R. Doc. 338, at 49-51.
    Asserting that compounding pharmacies commonly lack oversight and
    regulation, it is alleged that the use of compounding pharmacies “often results in drugs
    which are contaminated, sub-potent or super-potent, or which do not have the
    strength, quality or purity” of FDA-regulated drugs. R. Doc. 338, at. Ex. 6. These
    compounding pharmacies are alleged to be an “emerging, substandard drug industry”
    that are responsible for the creation of “large quantities of unregulated, unpredictable
    and potentially unsafe drugs.” R. Doc. 338, at Ex. 6. Noting that the lack of
    regulation allows compounding pharmacies to obtain ingredients from countries with
    little pharmaceutical oversight, it is alleged that it is impossible to trace the origin of
    the drugs, resulting in no guarantee that the drugs are what they purport to be. It is
    alleged that Missouri’s current compounded pentobarbital lethal-injection protocol is
    “replete with flaws that present a substantial risk of causing severe and unacceptable
    levels of pain and suffering during the execution.” R. Doc. 338, at Ex. 5.
    The prisoners also allege that the State might administer the execution drugs via
    central venous access rather than peripheral venous access.5 R. Doc. 338, at 30. The
    4
    pH is a measure of the acidity or basicity of a solution. See Taber’s Cyclopedic
    Medical Dictionary 1377 (Clayton L. Thomas ed., 16th ed. 1989). According to the
    affidavits attached to the prisoners’ second amended complaint, maintaining a proper
    pH is an important aspect of a properly produced drug. If a drug is too acidic or too
    basic, it may be incompatible with human blood, causing various unintended
    reactions. See R. Doc. 338, at Ex. 6.
    5
    Central venous access involves the insertion of a catheter into a large vein in
    a person’s neck, chest, or groin. Peripheral venous access involves the placement of
    -10-
    prisoners allege that the use of a central line carries a higher risk of complication in
    following the lethal-injection protocol, increases the length of the execution, and is
    more invasive and painful than peripheral venous access. R. Doc. 338, at 32.
    Notably, the prisoners make no mention of the central vein issues in their briefing
    before this court, instead focusing on alleged issues relating to the use of compounded
    pentobarbital. Because the prisoners have failed to brief this issue before our court,
    we decline to consider it here. See Neb. State Legislative Bd., United Transp. Union
    v. Slater, 
    245 F.3d 656
    , 658 n.3 (8th Cir. 2001) (explaining that claims not raised in
    an initial brief are waived).
    2.
    None of the alleged potentialities the prisoners identify in the second amended
    complaint relating to compounded pentobarbital rises to the level of “sure or very
    likely” to cause serious harm or severe pain. The prisoners’ allegations are limited to
    descriptions of hypothetical situations in which a potential flaw in the production of
    the pentobarbital or in the lethal-injection protocol could cause pain. This speculation
    is insufficient to state an Eighth Amendment claim. See Brewer v. Landrigan, 
    131 S. Ct. 445
    , 445 (2010) (“[S]peculation cannot substitute for evidence that the use of
    the drug is ‘sure or very likely to cause serious illness and needless suffering.’”
    (quoting 
    Baze, 553 U.S. at 50
    )). By noting that the use of compounding pharmacies
    “often results” in “potentially unsafe drugs,” the experts whose views have been
    incorporated into the second amended complaint underscore that the harms they have
    identified are hypothetical and not “sure or very likely” to occur. R. Doc. 338, at Ex.
    6. The prisoners rely on allegations of generalized harms resulting from the use of a
    compounding pharmacy to produce the pentobarbital and have failed to provide
    a catheter in a peripheral vein, most commonly in the hand or arm. See 6 The Gale
    Encyclopedia of Medicine 4571-72 (Laurie J. Fundukian ed., 4th ed. 2011).
    -11-
    anything more than speculation that the current protocol carries a substantial risk of
    severe pain.
    Even if one of the harms the prisoners identify were to occur, the prisoners offer
    nothing in their pleading to support the allegation that it would be more than an
    isolated incident. The prospect of an isolated incident does not satisfy the requirement
    that prisoners adequately plead a substantial risk of severe pain to survive a motion
    to dismiss their Eighth Amendment claim. See 
    Baze, 553 U.S. at 50
    (“[A]n isolated
    mishap alone does not give rise to an Eighth Amendment violation, precisely because
    such an event, while regrettable, does not suggest cruelty, or that the procedure at
    issue gives rise to a ‘substantial risk of serious harm.’” (quoting 
    Farmer, 511 U.S. at 842
    )). Accepting as true the factual matter alleged in the second amended complaint,
    if any of the hypothetical situations the prisoners identify came to pass, it would
    amount to an “isolated mishap” that, “while regrettable,” would not result in an Eighth
    Amendment violation.
    3.
    Case law from other circuits also supports our conclusion that the prisoners’
    allegation of a substantial risk of severe pain is inadequate. At least one court has
    found that an Eighth Amendment challenge to an execution protocol was properly
    dismissed after the plaintiff-prisoner failed to sufficiently plead a plausible claim that
    the lethal-injection protocol was sure or very likely to create a substantial risk of
    severe pain. See Cook v. Brewer, 
    637 F.3d 1002
    , 1008 (9th Cir. 2011). In Cook, the
    Ninth Circuit considered a challenge to Arizona’s lethal-injection protocol, a three
    drug protocol involving the use of sodium thiopental. 
    Id. The court
    found that the
    prisoner’s “reliance on speculative and conclusory allegations [was] insufficient to
    state a facially plausible claim” when he alleged that the use of non-FDA approved
    sodium thiopental created a substantial risk of severe pain. 
    Id. The prisoner
    alleged
    that the unregulated drug could be ineffective, contaminated, and could differ greatly
    -12-
    in potency, quality, and formation from other FDA regulated drugs. 
    Id. at 1006.
    The
    court rejected these claims as “speculative and overly generalized,” finding that the
    prisoner failed to make any specific factual allegations regarding the alleged harms
    arising from the use of an unregulated drug. 
    Id. Instead, he
    only identified
    hypothetical harms that would be “applicable to every drug produced outside the
    United States.” 
    Id. The court
    thus held that the bare allegations that the sodium
    thiopental was imported and non-FDA approved did not plausibly show that the drug
    was “sure or very likely to cause serious illness and needless suffering,” and the
    district court had properly dismissed the prisoner’s Eighth Amendment claim. 
    Id. at 1007.
    The same prisoner mounted a second challenge to Arizona’s use of sodium
    thiopental in its three drug lethal-injection protocol, alleging that the drug created a
    substantial risk of severe pain because there had been 12 adverse drug reaction
    reports, the drug had been manufactured for use on animals, it had caused problems
    in three executions in the United States, and the State obtained it unlawfully. Cook
    v. Brewer, 
    649 F.3d 915
    , 917 (9th Cir. 2011). The Ninth Circuit again upheld the
    dismissal of the prisoner’s complaint, finding that he had failed to satisfy the pleading
    requirements to state an Eighth Amendment claim. 
    Id. at 918-19.
    “Because Cook’s
    four new allegations do not support the drawing of any non-speculative conclusions,
    Cook has failed to state a facially plausible claim that Arizona’s planned execution is
    ‘sure or very likely to cause . . . needless suffering.’” Id. (quoting 
    Baze, 553 U.S. at 50
    ).
    Other circuits have also denied prisoners relief when challenging a compounded
    pentobarbital lethal-injection protocol. See Whitaker v. Livingston, 
    732 F.3d 465
    , 468
    (5th Cir.), cert. denied, 
    134 S. Ct. 417
    (2013) (affirming denial of motion for
    preliminary injunction when plaintiff-prisoners failed to show state’s execution
    protocol of compounded pentobarbital caused a substantial risk of severe pain when
    they had “pointed to only hypothetical possibilities” and were unable to “point to
    -13-
    some hypothetical situation, based on science and fact, showing a likelihood of severe
    pain”); Wellons v. Comm’r Ga. Dep’t of Corr., 
    754 F.3d 1260
    , 1265 (11th Cir. 2014)
    (affirming the denial of injunctive relief and declaratory judgment and denying a stay
    of execution when prisoner did not sufficiently allege that the use of compounded
    pentobarbital in the state’s execution protocol amounted to an Eighth Amendment
    violation because “speculation that a drug that has not been approved will lead to
    severe pain or suffering ‘cannot substitute for evidence that the use of the drug is sure
    or very likely to cause serious illness and needless suffering’” (quoting Mann v.
    Palmer, 
    713 F.3d 1306
    , 1315 (11th Cir. 2013)).
    4.
    The prisoners have failed to include factual allegations in the second amended
    complaint which permit the reasonable inference that Missouri’s lethal-injection
    protocol is “sure or very likely” to create a substantial risk of severe pain. Accepting
    the factual allegations in the complaint as true, the prisoners fail to satisfy their burden
    under the Eighth Amendment because they rely entirely on hypothetical and
    speculative harms that, if they were to occur, would only result from isolated mishaps.
    Like the prisoner in Cook, the prisoners here fail to make any specific factual
    allegations regarding the production of the pentobarbital that would lead to its
    contamination, potency problems, or improper pH, and instead rely on general risks
    associated with compounding pharmacies. Without such specific allegations, the
    prisoners’ complaint contains no more than speculative and hypothetical generalized
    assertions about the nature of compounding pharmacies. Likewise, the prisoners’
    allegation describing concerns arising from the method of venous access selected by
    the State amounts to no more than speculation. In sum, the prisoners have failed to
    plead sufficient factual matter, consistent with Twombly and Iqbal, necessary to state
    a plausible claim for relief. We conclude, therefore, that their claim regarding the
    substantial risk of severe pain allegedly imposed by Missouri’s execution protocol is
    inadequately pled as a matter of law.
    -14-
    B.
    Prisoners challenging a method of execution must do more than allege a
    substantial risk of serious harm to state a claim under the Eighth Amendment. As we
    explained in 
    Lombardi, 741 F.3d at 895
    -96, to establish a constitutional violation, an
    inmate ultimately must prove that another execution procedure exists that is feasible
    and readily implemented, and that the alternative method will significantly reduce a
    substantial risk of severe pain. 
    Lombardi, 741 F.3d at 895
    -96; see 
    Baze, 553 U.S. at 52
    (plurality opinion); 
    id. at 63
    (Alito, J., concurring); Raby v. Livingston, 
    600 F.3d 552
    , 560-61 (5th Cir. 2010); Cooey v. Strickland, 
    589 F.3d 210
    , 220 (6th Cir. 2009).
    The existence of such an alternative method of execution, therefore, is a necessary
    element of an Eighth Amendment claim, and this element—like any element of a
    claim—must be pleaded adequately.
    To address this point, the prisoners’ second amended complaint merely
    “concede[s] that other methods of lethal injection the Department could choose to use
    would be constitutional.” R. Doc. 338, at 148. In our view, this “concession” is
    insufficient to allege the second element of an Eighth Amendment claim that
    challenges a method of lethal injection. The complaint does not assert that the “other
    methods of lethal injection” it references are feasible and readily implemented, or that
    they would significantly reduce a substantial risk of severe pain allegedly caused by
    the present method. Even a barebones allegation to that effect, moreover, would not
    be adequate: a “formulaic recitation of the elements of a cause of action” is
    insufficient to state a claim under Rule 8(a)(2). 
    Iqbal, 556 U.S. at 678
    . The pleading
    must include “sufficient factual matter, accepted as true, to state a claim to relief that
    is plausible on its face.” 
    Id. (internal quotation
    marks omitted). The second amended
    complaint includes no factual matter that even hints at how the State—drawing on
    feasible and readily implemented alternatives—could modify its lethal-injection
    protocol to reduce significantly the alleged substantial risk of severe pain. We
    therefore agree with the district court that the prisoners’ “naked assertion” that other
    -15-
    methods would be constitutional, devoid of further factual enhancement, fails to state
    a claim under the Eighth Amendment.
    The prisoners respond that the Supreme Court’s decision in Hill v. McDonough,
    
    547 U.S. 573
    (2006), illustrates the sufficiency of their complaint. The issue in Hill
    was whether a prisoner’s challenge to the constitutionality of Florida’s lethal-injection
    protocol could proceed as an action for relief under 42 U.S.C. § 1983, or whether it
    must be brought as an action for a writ of habeas corpus under 28 U.S.C. § 2254. 
    Id. at 576.
    Hill’s complaint conceded that “other methods of lethal injection the
    Department could choose to use would be constitutional,” and the State had not
    argued that enjoining the present method “would leave the State without any other
    practicable, legal method of executing Hill by lethal injection.” 
    Id. at 580.
    The Court
    held under those circumstances that the action could proceed under § 1983, because
    “Hill’s action if successful would not necessarily prevent the State from executing him
    by lethal injection.” 
    Id. at 580.
    In reaching that conclusion, the Hill Court rejected a suggestion from the
    United States that a prisoner seeking to proceed under § 1983 rather than through
    habeas corpus must identify an alternative, authorized method of execution. 
    Id. at 582.
    The Court explained that it would not impose a “heightened pleading
    requirement[]” as a prerequisite to the prisoner proceeding under § 1983, because
    “[s]pecific pleading requirements are mandated by the Federal Rules of Civil
    Procedure, and not, as a general rule, through case-by-case determinations of the
    federal courts.” 
    Id. at 582
    (citing Fed. R. Civ. P. 8, 9; Swierkiewicz v. Sorema N.A.,
    
    534 U.S. 506
    , 512-14 (2002)).
    The Hill opinion’s references to Rule 8 and Swierkiewicz, and a later citation
    of Hill in Jones v. Bock, 
    549 U.S. 199
    , 213 (2007), have prompted our careful
    consideration. We think the better reading, however, is that Hill did not address the
    elements of a successful claim under the Eighth Amendment or establish that Hill’s
    -16-
    complaint stated a claim that would survive a motion to dismiss. The question
    decided in Hill concerned only the cognizability of a complaint under § 1983, as
    opposed to habeas corpus. The Court said specifically that “the merits of Hill’s
    underlying action are . . . not before us.” 
    Hill, 547 U.S. at 585
    . Whether Hill’s
    complaint stated a claim for relief under Rule 8 and the Eighth Amendment is a
    question that “goes to the merits” of the underlying action. Bond v. United States, 
    131 S. Ct. 2355
    , 2362 (2011). It was not until two years after Hill, in Baze, when the
    Court eventually addressed the substance of the Eighth Amendment and the elements
    of a claim challenging a lethal-injection protocol. Jones, also decided before Baze,
    simply reaffirmed a proposition with which we do not quarrel—i.e., that specific
    pleading requirements are mandated by the federal rules and generally not through
    case-by-case determinations of the 
    courts. 549 U.S. at 213
    . We disagree with Judge
    Shepherd, post, at 44, and the dissenting judges, post, at 38-40, that requiring a
    plaintiff to plead the elements of an Eighth Amendment claim as defined in Baze is
    a “heightened pleading requirement” that exceeds the requirements of Rule 8 as
    explained in Iqbal and Twombly.6
    The inference that Hill did not address the sufficiency of Hill’s complaint is
    strengthened by the opinions in Baze, where two Justices opined that “a method of
    execution violates the Eighth Amendment only if it is deliberately designed to inflict
    6
    Judge Bye, post, at 40-41, suggests incorrectly that this court’s order denying
    rehearing in Lombardi established that a prisoner could state an Eighth Amendment
    claim without identifying a feasible alternative if he merely conceded that other
    methods of lethal injection the State could choose to use would be constitutional. The
    Lombardi order simply recited the concession made by the plaintiffs in Hill, and
    observed that the plaintiffs in Lombardi did not make such an allegation. In re
    Lombardi, 
    741 F.3d 903
    , 905 (8th Cir. 2014). The order declared that “[w]e were not
    required to address whether alleging that the current method of execution creates a
    substantial risk of harm when compared to known and available alternatives, without
    specifying an alternative, would be sufficient to state a claim in light of Hill and
    Baze.” 
    Id. (emphasis added).
                                             -17-
    pain.” 
    Baze, 553 U.S. at 94
    (Thomas, J., concurring). Hill alleged only that Florida’s
    method of execution created a risk of severe pain and that other unspecified methods
    of execution would be constitutional; there is no indication in the opinion that he
    alleged a deliberate design by the State of Florida to inflict pain during an execution.
    That Hill was a unanimous opinion—joined by the concurring Justices in
    Baze—fortifies our view that the decision addressed only cognizability under § 1983,
    not the plausibility of the prisoner’s claim under Rule 8 and the Eighth Amendment.
    The prisoners contend alternatively that the rule announced in Baze applies only
    where—as in Baze itself—a prisoner alleges that a lethal-injection protocol is
    unconstitutional because the State easily could change to an alternative method of
    execution that is likely to reduce a significant risk of pain. We think that is an
    implausible reading of the Baze plurality opinion. On the prisoners’ view, a plaintiff
    who alleges a significant risk of severe pain and an alternative that would reduce the
    risk must satisfy the Baze standard for an alternative method of execution, but a
    prisoner who alleges only a significant risk of severe pain need not propose an
    alternative method. The suggested rule would render the Baze plurality’s extensive
    discussion of alternative methods superfluous, and we are loathe to assume that the
    plurality engaged in such a meaningless exercise. See 
    Baze, 553 U.S. at 56-61
    .
    The prisoners also urge that the Supreme Court’s grant of a stay of execution
    in Bucklew v. Lombardi, 
    134 S. Ct. 2333
    (2014), “repudiates the rule of Lombardi,”
    and shows that a prisoner need not allege an alternative method of execution to state
    a claim under the Eighth Amendment. In May 2014, the Court granted a stay of
    Russell Bucklew’s execution pending appeal in an order that stated as follows:
    Application for stay of execution of sentence of death presented to
    Justice ALITO and by him referred to the Court treated as an application
    for stay pending appeal in the United States Court of Appeals for the
    Eighth Circuit. Application granted pending disposition of petitioner’s
    -18-
    appeal. We leave for further consideration in the lower courts whether
    an evidentiary hearing is necessary.
    
    Id. The Court’s
    brief order does not address the substance of Bucklew’s appeal or
    the basis for possible success on the merits. Although Bucklew urged that the district
    court erred in requiring him to allege a feasible and more humane method of
    execution, he also asserted that “[t]o the extent that this Court, or any lower court,
    believes that pleading an ‘alternative method’ is necessary, Mr. Bucklew has indeed
    proposed an ‘alternative.’” App. 821-22. The unexplained order in Bucklew thus does
    not resolve whether the prisoners must plead the existence of an alternative method
    of execution that meets the criteria of Baze.
    The prisoners further contend that they cannot propose a reasonably available
    alternative method of execution without discovery of information about the State’s
    present suppliers of lethal drugs, so the Lombardi rule is unworkable in practice. We
    doubt the rule is as “unworkable” as the prisoners suggest. Their complaint is
    accompanied by affidavits from experts who criticize the use of compounded
    pentobarbital as a lethal drug. These or similar experts presumably are in a position
    to know and to inform the prisoners whether some other lethal drug exists that would
    significantly reduce the alleged risk of pain arising from the current method. In any
    event, the Supreme Court has rejected the notion that discovery must be available to
    a plaintiff who cannot allege sufficient factual matter to suggest plausibly an
    entitlement to relief. See 
    Twombly, 550 U.S. at 556-57
    . “Rule 8 marks a notable and
    generous departure from the hyper-technical, code-pleading regime of a prior era, but
    it does not unlock the doors of discovery for a plaintiff armed with nothing more than
    conclusions.” 
    Iqbal, 556 U.S. at 678
    -79.
    -19-
    Although policy reasons do not justify imposing a heightened pleading
    requirement, see 
    Swierkiewicz, 534 U.S. at 513
    , “the practical significance of the Rule
    8 entitlement requirement” should not be ignored. 
    Twombly, 550 U.S. at 557-58
    . In
    Twombly, the Court illustrated the practical significance of the Rule 8 requirement by
    adverting to the high cost of discovery in antitrust cases and the modest success of
    judicial supervision in checking discovery abuse. 
    Id. at 558-59.
    In this capital
    litigation, it should be remembered that one stated objective of the prisoners’ lawsuit
    is to pressure the State’s suppliers and agents to discontinue providing the drugs and
    other assistance necessary to carry out lawful capital sentences. The second amended
    complaint alleges that confidentiality of the States’ drug manufacturers and suppliers
    “prevents the . . . suppliers’ associations, customers, and prescribing or referring
    physicians from censuring or boycotting them,” and that protecting the identity of the
    State’s health care professionals unreasonably restricts their “associations and
    colleagues from de-certifying or otherwise censuring them or boycotting them.” R.
    Doc. 338, at 140-41.
    In this very case, after the State’s former drug supplier was identified through
    information in the public domain, a Missouri prisoner sued the supplier in Oklahoma.
    The supplier then elected to discontinue providing drugs to the State rather than
    endure the expense and burdens of litigation. R. Doc. 353, at 1-2, 10-13, 190-93. As
    for the possibility of protecting the confidentiality of sensitive identities after
    discovery in litigation, counsel for the prisoners expressed concern that it could be
    very difficult to investigate the physician, pharmacist, and laboratory without
    disclosing their roles in the execution process, and suggested there were “many ways
    in which investigating the pharmacy might place the pharmacy’s identity, status, and
    role at issue before whoever we would be talking to.” R. Doc. 224, at 12-16. The
    district court acknowledged that “it may be that there’s just no way given the
    circumstances to keep it confidential because of the central nature of these people to
    the current dispute.” 
    Id. at 16.
    -20-
    The real potential that unwarranted discovery would serve as a back-door means
    to frustrate the State’s ability to carry out executions by lethal injection counsels in
    favor of careful adherence to the requirements of Rule 8, as explicated in Iqbal and
    Twombly. A groundless Eighth Amendment claim should not be permitted to achieve
    indirectly a de facto injunction against a lawful method of execution.
    For these reasons, we adhere to our conclusion in Lombardi that without a
    plausible allegation of a feasible alternative method of execution that would
    significantly reduce a substantial risk of serious pain, or a purposeful design by the
    State to inflict unnecessary pain, the prisoners have not stated an Eighth Amendment
    claim based on the State’s use of compounded pentobarbital in executions. We further
    conclude that the allegation in the second amended complaint that “other methods of
    lethal injection the Department could choose would be constitutional” does not
    contain sufficient factual matter to state a claim to relief that is plausible on its face.
    The district court thus properly dismissed the prisoners’ Eighth Amendment claim.7
    7
    Judge Shepherd, while voting to affirm, also files a “dissenting” opinion on the
    ground that Part II.B is unnecessary to the decision. It is not uncommon for courts to
    decide cases on alternative grounds, e.g., United States v. Farlee, 
    757 F.3d 810
    , 820
    (8th Cir. 2014), and the Supreme Court recently noted the “unremarkable proposition”
    that a court’s decision to rely on one of two possible alternative grounds does not strip
    it of power to decide the second question, particularly when the court’s decree is
    subject to review by the Supreme Court. Already, LLC v. Nike, Inc., 
    133 S. Ct. 721
    ,
    729 (2013). Given our conclusion in Part II.B, moreover, it could just as well be said
    that Part II.A concerning the complaint’s allegations of a substantial risk of severe
    pain is unnecessary. Indeed, this court in Lombardi (joined by Judge Shepherd)
    concluded that a previous complaint filed by the prisoners failed to state a claim solely
    because the prisoners did not make a sufficient allegation about an alternative method
    of 
    execution. 741 F.3d at 895-96
    .
    -21-
    III.
    The prisoners next argue that they have a serious medical need to be free from
    gratuitous pain during their executions, and that the state officials act with deliberate
    indifference to their need by using compounded pentobarbital as the lethal drug in the
    State’s execution procedure. The district court rejected this claim on two grounds: (1)
    that the officials are not addressing medical needs of the prisoners in carrying out
    executions, and (2) that the prisoners have not pleaded adequately that the State’s
    lethal-injection protocol inflicts unnecessary pain in violation of the Eighth
    Amendment.
    Assuming without deciding that an Eighth Amendment deliberate-indifference
    claim based on medical needs is not limited to cases involving medical procedures,
    see Nelson v. Campbell, 
    541 U.S. 637
    , 644-45 (2004); 
    Helling, 509 U.S. at 29-30
    , we
    agree with the district court that the prisoners have not stated a claim. The Eighth
    Amendment protects against the “unnecessary and wanton infliction of pain.” Estelle
    v. Gamble, 
    429 U.S. 97
    , 104 (1976). A prisoner must allege both that a deprivation
    of rights is “objectively, sufficiently serious,” and that a state official is deliberately
    indifferent to inmate health or safety. 
    Farmer, 511 U.S. at 834
    (internal quotation
    omitted). For reasons discussed in Part II, the prisoners have not pleaded that the use
    of compounded pentobarbital will result in the unnecessary and wanton infliction of
    pain.
    IV.
    The prisoners contend that the state officials violated the Ex Post Facto Clause
    of the federal Constitution when they changed the execution protocol to provide for
    the use of compounded pentobarbital, because the change allegedly increased the risk
    of a painful execution. The Ex Post Facto Clause forbids enactment of a “law that
    changes the punishment, and inflicts a greater punishment, than the law annexed to
    -22-
    the crime, when committed.” Cal. Dep’t of Corr. v. Morales, 
    514 U.S. 499
    , 516
    (1995) (quoting Calder v. Bull, 
    3 U.S. 386
    , 390 (1798)). The prisoners’ claim fails
    in light of Lombardi, where this court held that an identical ex post facto claim
    asserted in an earlier complaint failed to state a 
    claim. 741 F.3d at 896-97
    . We
    reasoned that “[t]he manner of punishment for capital murder in Missouri at all
    relevant times . . . has been death by lethal injection or lethal gas.” 
    Lombardi, 741 F.3d at 896
    (citing Mo. Rev. Stat. § 546.720.1). Where, as here, “only the mode of
    producing death has changed, with no allegation of superadded punishment or
    superior alternatives, the Ex Post Facto Clause[ is] not implicated.” 
    Id. at 897
    (internal quotation mark omitted).
    The prisoners also complain that they did not have fair notice that Director
    Lombardi could change the method of execution to include compounded
    pentobarbital, because that method allegedly violates the federal Food, Drug, and
    Cosmetics Act and the Controlled Substances Act. The prisoners note Lombardi’s
    statement that when the prisoners committed their crime, they “had fair notice” that
    death was the prescribed punishment, and fair notice “of the Director’s discretion to
    determine the method of 
    execution.” 741 F.3d at 897
    . The Ex Post Facto Clause,
    however, is concerned with “lack of fair notice and governmental restraint when the
    legislature increases punishment beyond what was prescribed when the crime was
    consummated.” Weaver v. Graham, 
    450 U.S. 24
    , 30 (1981). Whether the prisoners
    had specific notice that the Director might select a particular lethal drug is not
    dispositive, so long as the State has not increased the punishment for the offenses of
    conviction. We therefore adhere to our conclusion in Lombardi that the prisoners fail
    to state a plausible ex post facto claim because the punishment—death—has remained
    the same; “only the mode of producing death has changed,” and the prisoners have not
    alleged “superadded punishment or superior 
    alternatives.” 741 F.3d at 897
    (internal
    quotation mark omitted).
    -23-
    V.
    The prisoners next contend that the Missouri state officials violated their right
    of access to the courts under the Due Process Clause by failing to provide them with
    the timely and adequate notice of the proposed execution method needed to litigate
    the lawfulness of the execution protocol. We agree with the district court that the
    prisoners failed to state a claim based on alleged infringement of their right to access
    the courts. State prisoners have a constitutional “right of access to the courts,” Lewis
    v. Casey, 
    518 U.S. 343
    , 350 (1996) (emphasis omitted), but this right does not
    guarantee the ability “to discover grievances, and to litigate effectively once in court.”
    
    Id. at 354.
    The right of access to the courts is satisfied if the prisoner has “the
    capability of bringing contemplated challenges to sentences or conditions of
    confinement before the courts.” 
    Lewis, 518 U.S. at 356
    . The prisoners’ claim that
    they are unable to discover information regarding the execution protocol is thus
    insufficient as a matter of law to state a due process claim. 
    Lewis, 518 U.S. at 354
    ;
    Williams v. Hobbs, 
    658 F.3d 842
    , 851-52 (8th Cir. 2011); Giarratano v. Johnson, 
    521 F.3d 298
    , 306 (4th Cir. 2008). “The prisoners do not assert that they are physically
    unable to file an Eighth Amendment claim, only that they are unable to obtain the
    information needed to discover a potential Eighth Amendment violation.” 
    Williams, 658 F.3d at 852
    .
    On appeal, the prisoners present a new argument—that their “life interest
    entitles them to notice of material information about the lethal drug with which they
    will be executed.” They rely on the procedural due process decision of Mathews v.
    Eldridge, 
    424 U.S. 319
    (1976), and urge that the private interests served by disclosure
    and the risk of an erroneous deprivation of rights without disclosure outweigh the
    State’s interest in avoiding disclosure of details about the lethal drug and its
    provenance.
    -24-
    The prisoners did not develop an argument based on Mathews in the district
    court, and it is too late to raise it for the first time on appeal. In any event, the analogy
    to Mathews is inapt. Mathews involved an undisputed deprivation of a property
    interest (denial of social security benefits), and the question was whether the claimant
    was entitled by the Due Process Clause to a pre-deprivation hearing as opposed to
    merely a post-deprivation hearing. 
    Id. at 332-33.
    The prisoners in this case already
    have received due process for the deprivation of their life interests: They were
    convicted and sentenced to death after a trial in Missouri court, and their convictions
    and sentences were upheld on appeal.
    At this point, the prisoners seek to discover information about the State’s lethal-
    injection protocol in order to determine whether the protocol violates the Eighth
    Amendment. The prisoners, however, have not pleaded a deprivation of rights under
    the Eighth Amendment. This is not a case like Mathews, therefore, where there was
    an undisputed deprivation of an interest protected by the Due Process Clause, and the
    question was what process is due before the State may accomplish the deprivation.
    
    Id. Rather, the
    prisoners here—like the plaintiffs in 
    Wellons, 754 F.3d at 1267
    , and
    Sepulvado v. Jindal, 
    729 F.3d 413
    , 419-20 (5th Cir. 2013)—claim a freestanding right
    to detailed disclosure about Missouri’s execution protocol. We agree with the
    Eleventh and Fifth Circuits that the Constitution does not require such disclosure.
    
    Wellons, 754 F.3d at 1267
    ; 
    Sepulvado, 729 F.3d at 419-20
    . A prisoner’s “assertion
    of necessity—that [the State] must disclose its protocol so he can challenge its
    conformity with the Eighth Amendment—does not substitute for the identification of
    a cognizable liberty interest.” 
    Sepulvado, 729 F.3d at 419
    .
    VI.
    The prisoners next press a claim that the Missouri officials violate the Equal
    Protection Clause by executing prisoners while legal activity seeking to stay their
    executions is pending, because the practice contravenes the State’s written
    -25-
    Chronological Sequence of Execution policy. They cite the executions of Joseph
    Franklin, Alan Nicklasson, and Herbert Smulls, which were carried out while a
    pleading was pending in the district court, the court of appeals, or the Supreme Court.
    The prisoners’ theory is that forestalling executions until all litigation is finished is a
    “core” provision of the execution protocol, and that deviating from a “core” provision
    violates their rights to equal protection of the laws.
    The relevant portion of the execution policy provides that at 11:15 p.m. on the
    eve of an execution:
    Director of the Department of Corrections/designee advises (ERDCC
    Warden) that (Inmate Name) may be escorted to the execution room if
    no stay is in place and no legal activity is in progress to prevent the
    execution.
    If there is pending legal activity to halt the execution process, (Inmate
    Name) will remain in his holding cell and there will be no IV or line
    established until authority is granted to do so by the Director of the
    Department of Corrections/designee.
    App. 335-36.
    The prisoners contend that the policy permits the Director to grant the Warden
    authority to escort a prisoner from his cell to the execution chamber only if there is no
    legal activity in progress designed to halt the execution. They reason that if the
    second paragraph of the policy allowed the Director to initiate an execution procedure
    even while legal proceedings were pending, then the first paragraph concerning
    actions taken when “no legal activity is in progress” would be superfluous.
    The prisoners’ reading of the policy is unlikely: It would allow an inmate to
    thwart the State’s ability to carry out a lawful sentence simply by making repeated
    court filings designed to prevent an execution during the 24-hour period designated
    -26-
    by the Supreme Court of Missouri for carrying out the sentence. One can imagine
    counsel for a prisoner even asserting an ethical obligation to ensure that some legal
    activity remains in progress for a full twenty-four hours. We are skeptical of an
    interpretation of the State’s policy that could effectively foreclose the State’s ability
    to carry out lawful sentences.
    The policy is not a model of clarity, but it should not be understood to forbid
    an execution whenever there is pending legal activity designed to stop the execution.
    The policy does not expressly require the Director to refrain from carrying out a
    sentence until legal activity has ceased. To the contrary, the second paragraph quoted
    above contemplates that the Director may grant the Warden authority to begin
    preparations for an execution even when legal activity is ongoing. The first quoted
    provision—that the Director may advise the Warden to escort the inmate to the
    execution room if no legal activity is in progress—applies by its terms only at 11:15
    p.m. on the eve of a date of execution. The chronology does not address a
    circumstance in which legal activity delays an execution until later in the 24-hour
    period. The second quoted paragraph implies that the Director retains authority to
    begin preparations for an execution at a later time despite ongoing legal activity. The
    prisoners do not allege that the officials have escorted inmates to the execution room
    on the eve of the execution while legal activity is pending: In the cases of Franklin,
    Nicklasson, and Smulls, a district court or a panel of this court entered a stay of
    execution that was later vacated, and the State eventually proceeded later in the 24-
    hour period authorized for the execution. We therefore conclude that the prisoners
    have not stated a claim under the Equal Protection Clause based on alleged violations
    of the Department’s execution policy.
    Assuming for the sake of analysis, however, that the state officials deviate from
    the execution protocol by carrying out sentences while legal activity is pending, the
    practice does not violate the Constitution. “The Equal Protection Clause of the
    Fourteenth Amendment commands that no State shall ‘deny to any person within its
    -27-
    jurisdiction the equal protection of the laws,’ which is essentially a direction that all
    persons similarly situated should be treated alike.” City of Cleburne v. Cleburne
    Living Ctr., 
    473 U.S. 432
    , 439 (1985). “If a legislative classification or distinction
    neither burdens a fundamental right nor targets a suspect class, we will uphold it so
    long as it bears a rational relation to some legitimate end.” Vacco v. Quill, 
    521 U.S. 793
    , 799 (1997) (internal quotation marks and brackets omitted).
    The prisoners apparently invoke the “fundamental right” strand of equal
    protection analysis. They argue that it is unconstitutional for the State to disregard a
    “core provision” of its execution protocol, and that a prohibition on executions before
    legal activity has ceased is a “core provision.” The prisoners draw the term “core
    provision” from two decisions of a district court concerning Ohio’s execution
    protocol. See Cooey v. Kasich, 
    801 F. Supp. 2d 623
    (S.D. Ohio 2011); In re Ohio
    Execution Protocol Litig., 
    840 F. Supp. 2d 1044
    (S.D. Ohio), aff’d, 
    671 F.3d 601
    (6th
    Cir. 2012). The Ohio district court reasoned that because certain “core” provisions
    of the State’s execution protocol were the “precise procedural safeguards” that had
    been “heralded in prior discussions of Eighth Amendment claims” in the same
    litigation, “core deviations” from the protocol burdened a prisoner’s “fundamental
    right” for purposes of equal protection analysis. 
    Cooey, 801 F. Supp. 2d at 652-53
    .
    The court thought certain “core deviations . . . subverted the key constitutional
    principles that control the execution process.” In re Ohio Execution Protocol 
    Litig., 840 F. Supp. 2d at 1049
    . See also Arthur v. Thomas, 
    674 F.3d 1257
    , 1263 (11th Cir.
    2012) (concluding that an inmate stated an equal protection claim by alleging that the
    State of Alabama substantially deviated from an execution protocol, because
    “[s]ignificant deviations from a protocol that protects inmates from cruel and unusual
    punishment can violate the Eighth Amendment”).
    Whatever the merits of the Ohio district court’s analysis with regard to the
    execution protocol at issue in those decisions, the prisoners here have not stated a
    claim that Missouri’s alleged deviations from its protocol burden a fundamental right.
    -28-
    There is no “fundamental right” to avoid execution while no judicial stay is in effect
    but legal activity is pending. E.g., Hamilton v. Texas, 
    497 U.S. 1016
    (1990) (denying
    stay of execution despite four votes to grant writ of certiorari). Fundamental rights
    consist of only those rights that are “explicitly or implicitly guaranteed by the
    Constitution.” San Antonio Indep. Sch. Dist. v. Rodriguez, 
    411 U.S. 1
    , 32-34 (1973).
    The State’s decision to carry out a lawful sentence when there is no judicial stay in
    place does not burden a prisoner’s rights under the Eighth Amendment or other
    constitutional provision. If a prisoner advances an eleventh-hour challenge to an
    execution, the courts have authority to enter temporary administrative stays of
    execution when necessary and appropriate to allow consideration of constitutional
    claims. The State may deem it prudent to delay an execution while litigation is
    pending, especially when final resolution is likely to occur before time expires for
    carrying out the sentence on the appointed date. But the Constitution does not require
    the State to implement a self-imposed stay when a state or federal court has declined
    to act.
    VII.
    The prisoners also argue that they stated a claim that the First Amendment
    entitles them to information regarding the source of the drug to be used in their
    executions. A Missouri statute, Mo. Rev. Stat. § 546.720.2, provides that “[t]he
    identities of members of the execution team, as defined in the execution protocol of
    the department of corrections, shall be kept confidential.” The prisoners contend that
    the statute violates their First Amendment rights insofar as it permits Missouri to
    conceal the identity of the compounding pharmacy that provides the pentobarbital and
    the identities of the pharmacy’s suppliers of ingredients for the compounding process.
    The prisoners argue that concealing this information violates their right of access to
    records associated with governmental execution proceedings and constitutes an
    impermissible content-based restriction on access to information.
    -29-
    A divided panel of the Ninth Circuit, considering a comparable First
    Amendment claim, recently enjoined the execution of an Arizona inmate until the
    State provided him with the name and provenance of drugs to be used in his
    execution. The Supreme Court promptly vacated the injunction without dissent.
    Wood v. Ryan, 
    759 F.3d 1076
    , 1088 (9th Cir.), vacated, 
    135 S. Ct. 21
    (2014). The
    Eleventh Circuit has ruled that the First Amendment does not grant a prisoner a right
    “to know where, how, and by whom the lethal injection drugs will be manufactured.”
    
    Wellons, 754 F.3d at 1266-67
    . See also Owens v. Hill, 
    758 S.E.2d 794
    , 805-06 (Ga.
    2014). We agree with the Eleventh Circuit and the dissenting opinion in the Ninth
    Circuit and conclude that the prisoners failed to state a claim under the First
    Amendment.
    The Supreme Court held in Press-Enterprise Co. v. Superior Court, 
    478 U.S. 1
    , 8-13 (1986), that the public enjoys a qualified right of access to certain criminal
    proceedings. The Court has recognized this right of access in preliminary hearings,
    
    id. at 10,
    criminal trials, Richmond Newspapers, Inc. v. Virginia, 
    448 U.S. 555
    , 579-80
    (1980), and voir dire, Press-Enterprise Co. v. Superior Court, 
    464 U.S. 501
    , 505-11
    (1984). This court has held that the First Amendment right of access applies to some
    records filed in criminal proceedings—specifically, documents filed in support of
    search warrant applications—see In re Search Warrant for Secretarial Area Outside
    Office of Gunn, 
    855 F.2d 569
    , 572-73 (8th Cir. 1988), but unlike the Ninth Circuit, we
    have not ruled that an execution constitutes the kind of criminal proceeding to which
    the public enjoys a qualified right of access under the First Amendment. Cf. Cal. First
    Amendment Coal. v. Woodford, 
    299 F.3d 868
    , 877 (9th Cir. 2002).
    Assuming for the sake of analysis, however, that the Press-Enterprise analysis
    applies to executions, and even to information regarding the source of drugs to be
    used in lethal injections, the prisoners fail to state a claim for a qualified right of
    public access. To determine whether a First Amendment public right of access
    attaches to a particular proceeding, courts consider “whether the place and process
    -30-
    have historically been open to the press and general public” and “whether public
    access plays a significant positive role in the functioning of the particular process in
    question.” 
    Press-Enterprise, 478 U.S. at 8
    . In Press-Enterprise, the Court evaluated
    whether the preliminary hearings at issue had a “tradition of accessibility” under the
    first prong of the analysis, and concluded that from the early nineteenth century “until
    the present day, the near uniform practice of state and federal courts has been to
    conduct preliminary hearings in open 
    court.” 478 U.S. at 10
    .
    The prisoners assert that they have a similar right to know the identities of the
    pharmacy that compounds the pentobarbital and of its suppliers of chemicals, yet they
    fail to allege a “tradition of accessibility” to that information. We have reserved
    judgment about whether even an execution itself must be made public, Rice v.
    Kempker, 
    374 F.3d 675
    , 678 n.2 (8th Cir. 2004), and the prisoners have not alleged
    facts or cited authority establishing that the particulars of execution methods have
    “historically been open to the press and general public.” 
    Press-Enterprise, 478 U.S. at 8
    . The prisoners have alleged only that Missouri did not include the suppliers of
    drugs for lethal injections as members of the confidential execution team before
    October 2013. That the identities of the drug suppliers were not made confidential by
    statute or regulation before October 2013 falls well short of the required “tradition of
    accessibility” that might give rise to a right of access. Indeed, the prisoners do not
    even allege that the information was accessible to the public before October 2013.
    Even if the prisoners can show, moreover, that Missouri “at one time voluntarily
    disclosed such information, it does not a tradition make.” 
    Wood, 759 F.3d at 1095
    (Bybee, J., dissenting). In sum, the prisoners fail to state a claim of a qualified right
    of public access to information regarding the source of the compounded pentobarbital
    to be used in their executions because they do not plausibly allege a history of
    openness to the general public. The complaint likewise provides no basis to conclude
    that public access to detailed information about execution protocols plays a significant
    positive role in the functioning of the process in question, given that the practical
    -31-
    effect of public disclosure would likely be frustration of the State’s ability to carry out
    lawful sentences.
    The prisoners also argue that the confidentiality requirements of § 546.720.2
    constitute a content-based restriction on access to information that merits strict
    scrutiny. They rely on Sorrell v. IMS Health Inc., 
    131 S. Ct. 2653
    (2011), where the
    Court held that a Vermont law prohibiting the sale and use of pharmaceutical
    prescriber-identifying information was a restriction on “speech with a particular
    content,” because sale of that information was permitted in certain exceptional
    situations “based in large part on the content of a purchaser’s speech,” and subsequent
    use of the information was limited to non-marketing purposes. 
    Id. at 2662-63.
    The
    Missouri statute challenged by the prisoners is different. The statute does not limit the
    dissemination of identities of execution team members based on the identity of the
    individual seeking that information and the likely content of that individual’s speech,
    and the law does not limit the use of any such information to certain types of speech.
    The prisoners thus fail to state a claim that § 546.720.2 is a content-based restriction
    on access to information that merits strict scrutiny.
    VIII.
    The prisoners complain that the use of compounded pentobarbital as a lethal
    drug in executions violates the federal Food, Drug, and Cosmetic Act, 21 U.S.C.
    §§ 301, et seq., and the Controlled Substances Act. 21 U.S.C. §§ 801, et seq. They
    acknowledge, however, that there is no private right of action under federal law to
    enforce these alleged violations. 23 U.S.C. § 337(a); Buckman Co. v. Plaintiffs’ Legal
    Comm., 
    531 U.S. 341
    , 349 n.4 (2001); Durr v. Strickland, No. 2:10-cv-288, 
    2010 WL 1610592
    , at *2-3 (S.D. Ohio), aff’d, 
    602 F.3d 788
    , 789 (6th Cir. 2010) (affirming
    district court’s holding that no private right of action exists under the Controlled
    Substances Act). Instead, they assert that the Missouri Administrative Procedure Act
    -32-
    gives them a private right of action to sue for alleged violations of the federal statutes.
    The district court ruled that the prisoners failed to state a claim.
    Under the Missouri APA, where there is no formal hearing before a state
    agency in a contested case, a court may review a decision of an administrative officer
    or body that “determin[es] the legal rights, duties or privileges of any person.” Mo.
    Rev. Stat. § 536.150.1; see City of Valley Park v. Armstrong, 
    273 S.W.3d 504
    , 506-07
    (Mo. 2009) (en banc); State ex rel. Yarber v. McHenry, 
    915 S.W.2d 325
    , 327-28 (Mo.
    1995) (en banc). The court may determine whether the decision is “unconstitutional,
    unlawful, unreasonable, arbitrary, or capricious or involves an abuse of discretion.”
    Mo. Rev. Stat. § 536.150.1.
    The prisoners fail to state a claim under the Missouri APA because they have
    not alleged that the decision of corrections officials to adopt the execution protocol
    determines their “legal rights, duties or privileges.” “Section 536.150 pertains only
    to review of decisions affecting private rights and interests.” St. Louis Cnty v. State
    Tax Comm’n, 
    608 S.W.2d 413
    , 414 (Mo. 1980) (en banc). “[T]o make a prima facie
    case under Section 536.150, an individual must plead facts that, if true, would show
    that he has been denied some legal right or entitlement to a privilege.” McIntosh v.
    LaBundy, 
    161 S.W.3d 413
    , 416 (Mo. Ct. App. 2005). The plaintiff must thus identify
    a “rule, statute, or other authority creating a legal right or entitlement.” 
    Id. at 417.
    The prisoners allege a right not to “be executed in a manner that violates federal
    laws protecting the end-users of regulated pharmaceuticals.” They fail, however, to
    identify a statute or other authority that creates a private legal right or entitlement.
    The federal statutes cited in the complaint do not create private rights of action. The
    prisoners cannot employ the Missouri APA to allege the denial of a private legal right
    under the federal statutes when the federal statutes themselves do not create such a
    private legal right.

    *       *       *
    The judgment of the district court is affirmed.
    BYE, Circuit Judge, with whom MURPHY and KELLY, Circuit Judges, join,
    dissenting.
    The constitutionality of the death penalty itself is not before us in this case, and
    we proceed on the assumption the death penalty is constitutional. While it follows
    there must be a constitutional means of carrying out a death sentence, it has not been
    determined that Missouri's current execution protocol is constitutional. The district
    court erred in dismissing the death-row inmates' suit, and the death-row inmates
    should have the opportunity to conduct discovery and fully litigate their claims. I
    therefore respectfully dissent.
    I
    I disagree with the entirety of Part II of the majority's opinion, which dismisses
    the death-row inmates' Eighth Amendment claim. The majority provides two
    alternative reasons for dismissing the suit: (1) as a matter of law, the death-row
    inmates' claim regarding the substantial risk of severe pain imposed by Missouri's
    execution protocol is inadequately pled; and (2) the death-row inmates have failed to
    adequately plead a readily-available alternative method of execution.
    A
    The majority first holds the death-row inmates have failed to plead sufficient
    factual matter on the risk of harm to state a plausible claim of relief. Federal Rule of
    Civil Procedure 8(a)(2) requires only "a short and plain statement of the claim
    showing that the pleader is entitled to relief." To withstand the State's Rule 12(b)(6)
    -34-
    motion, the complaint must contain sufficient factual allegations to "state a claim to
    relief that is plausible on its face." Bell Atl. Corp. v. Twombly, 
    550 U.S. 544
    , 547
    (2007). "Threadbare recitals of the elements of a cause of action, supported by mere
    conclusory statements, do not suffice." Ashcroft v. Iqbal, 
    556 U.S. 662
    , 678 (2009)
    (citing 
    Twombly, 550 U.S. at 555
    ).
    "[T]aking all facts alleged in the complaint as true, and making reasonable
    inferences in favor of the nonmoving party," the death-row inmates have sufficiently
    pled their Eighth Amendment claim. Smithrud v. City of St. Paul, 
    746 F.3d 391
    , 397
    (8th Cir.) cert. denied, 
    135 S. Ct. 361
    (2014). The death-row inmates' complaint
    alleges the compounded pentobarbital used by Missouri creates a substantial risk of
    harm and inflicts a substantial risk of severe pain. The death-row inmates have also
    shown the risk of pain is objectively intolerable.
    The death-row inmates' second amended complaint includes thirty-two attached
    exhibits, including declarations and affidavits from medical professionals. The
    pleadings demonstrate substantial concerns with compounded pentobarbital, including
    potency levels, contamination, pH levels, and shelf-life. Despite such pleadings, the
    majority concludes these potentialities are hypothetical and do not "rise[] to the level
    of 'sure or very likely' to cause serious harm or severe pain." The majority takes
    offense at the death-row inmates' "allegations of generalized harms" from
    compounded pentobarbital, but such allegations are exactly what must be pled to
    survive a Rule 12(b)(6) motion to dismiss. Rule 8 only requires "a short and plain
    statement" showing the death-row inmates are entitled to relief. No higher pleading
    standard is applicable to this suit. Cf. Fed. R. Civ. P. 9(b) (establishing heightened
    pleading standards in certain cases, such as fraud or mistake). The death-row inmates
    could not possibly include allegations more specific to the compounding done for or
    by Missouri without the benefit of discovery. To know about Missouri's particular
    compounding procedure and the particular dangers of such a procedure, the death-row
    inmates need discovery about the various sources of the drugs, how the drugs are
    -35-
    compounded, whether the compounded drugs are tested for potency, contamination,
    or pH levels, and how and for how long the compounded drugs are stored. Missouri
    has steadfastly refused to disclose any information related to the compounded
    pentobarbital. See e.g., In re Lombardi, 
    741 F.3d 888
    , 889 (8th Cir.), reh'g denied,
    
    741 F.3d 903
    (8th Cir.) and cert. denied sub nom. Zink v. Lombardi, 
    134 S. Ct. 1790
    (2014) (ruling in favor of Missouri in an appeal "to prohibit the district court from
    enforcing orders that [the State] must disclose in civil discovery, for use by opposing
    counsel, the identities of (1) the physician who prescribes the chemical used in
    Missouri executions, (2) the pharmacist who compounds the chemical, and (3) the
    laboratory that tests the chemical for potency, purity, and sterility"). It is not the
    death-row inmates' burden at the pleading stage to show their claims are "sure or very
    likely;" the death-row inmates must merely show they have stated a claim for relief.
    The majority is unconcerned with expert opinions and a host of other evidence
    which shows improperly compounded pentobarbital would "sure or very likely" cause
    unconstitutionally painful deaths. The majority acknowledges this evidence exists but
    focuses on the one thing the death-row inmates cannot know at this stage: "specific
    factual allegations regarding the production of the pentobarbital" to be used in their
    executions. Because the death-row inmates have adequately pled that improperly
    compounded pentobarbital is sure or very likely to cause pain and suffering at an
    unconstitutional level, the death-row inmates have pled enough to survive a motion
    to dismiss under Rule 12(b)(6). Thus, the death-row inmates should be allowed to
    utilize discovery in the normal course of litigation to determine the actual process used
    by Missouri's current compounding pharmacies.
    B
    In an alternative holding on the death-row inmates' Eighth Amendment claim,
    the majority finds the death-row inmates failed to plead a specific readily-available
    alternative method of execution and finds such a failure fatal to this suit. I disagree.
    -36-
    In Hill v. McDonough, 
    547 U.S. 573
    , 576 (2006), the Supreme Court examined
    whether a death-row inmate challenging Florida's execution protocol had a cognizable
    suit under 42 U.S.C. § 1983, or whether such a claim needed to be brought under 28
    U.S.C. § 2254. The Supreme Court clarified that a challenge to a state's execution
    procedure may proceed under § 1983, particularly when a "[c]omplaint does not
    challenge the lethal injection sentence as a general matter but seeks instead only to
    enjoin [the State] from executing [the plaintiff] in the manner they currently intend."
    
    Hill, 547 U.S. at 580
    (internal quotation marks omitted). In explaining the
    requirements for a § 1983 challenge to execution protocols, the Supreme Court
    considered and rejected the proposition that "a capital litigant's § 1983 action can
    proceed [only] if . . . the prisoner identified an alternative, authorized method of
    execution." 
    Id. at 582.
    In rejecting that proposition, the Supreme Court explained
    "[i]f the relief sought would foreclose execution, recharacterizing a complaint as an
    action for habeas corpus might be proper." 
    Id. "Imposition of
    heightened pleading
    requirements, however, is quite a different matter. Specific pleading requirements are
    mandated by the Federal Rules of Civil Procedure, and not, as a general rule, through
    case-by-case determinations of the federal courts." 
    Id. (citing Fed.
    R. Civ. P. 8 and
    9; Swierkiewicz v. Sorema N.A., 
    534 U.S. 506
    , 512-14 (2002)).
    A year later, the Supreme Court addressed the pleading requirements of
    exhaustion under the Prison Litigation Reform Act in Jones v. Bock, 
    549 U.S. 199
    (2007). The Supreme Court, relying on the Federal Rules of Civil Procedure and
    rejecting a heightened pleading requirement, found the usual practice under the
    Federal Rules should be followed in § 1983 suits. The Supreme Court thereafter
    reaffirmed the pleading requirements for death-row inmates: "And just last Term, in
    Hill . . . , we unanimously rejected a proposal that § 1983 suits challenging a method
    of execution must identify an acceptable alternative." 
    Id. at 212.
    In addressing the
    pleading requirements for death-row inmates challenging a method of execution, the
    Supreme Court has been clear: there is no heightened pleading rule requiring inmates
    to identify any alternative method of execution.
    -37-
    The majority dismisses these clear statements by the Supreme Court, and
    instead relies on Baze v. Rees, 
    553 U.S. 35
    (2008), to justify the imposition of a
    heightened pleading standard. The Baze challenge to Kentucky's three-drug execution
    protocol came to the Supreme Court in a declaratory judgment action after "[t]he trial
    court held extensive hearings and entered detailed findings of fact and conclusions of
    law." 
    Id. at 41.
    The death-row inmates in Baze, challenging Kentucky's execution
    protocol, alleged a readily-available alternative. The Supreme Court held "a
    condemned prisoner cannot successfully challenge a State's method of execution
    merely by showing a slightly or marginally safer alternative." 
    Id. at 51.
    Rather, the
    Supreme Court established that when an alternative method of execution is proposed,
    "the proffered alternatives must effectively address a substantial risk of serious harm."
    
    Id. at 52
    (internal quotation marks omitted). And, if a death-row inmate puts forward
    such a proposed alternative, it must be "feasible, readily implemented, and . . .
    significantly reduce a substantial risk of severe pain." 
    Id. Baze does
    not establish the standard for all execution-protocol challenges.
    Instead, Baze establishes that when death-row inmates can show a readily-available
    alternative with sufficient documented advantages, "a State's refusal to change its
    method can be viewed as 'cruel and unusual' under the Eighth 
    Amendment." 553 U.S. at 52
    . Baze reaches no further than this holding. Baze did not purport to limit Eighth
    Amendment challenges of execution protocols to only those cases where death-row
    inmates propose an alternative method, and Baze did not change the pleading
    requirements for Eighth Amendment cases.
    Despite the limited nature of Baze, the majority relies on Baze to establish that
    death-row inmates must plead a feasible and readily-available alternative method of
    execution. It is troubling the majority relies on Baze when Baze does not mention
    pleading requirements or the Federal Rules of Civil Procedure. Webster v. Fall, 
    266 U.S. 507
    , 511 (1925) ("Questions which merely lurk in the record, neither brought to
    the attention of the court nor ruled upon, are not to be considered as having been so
    -38-
    decided as to constitute precedents."). But perhaps most troubling is the majority's
    reliance on Baze when Baze does not even mention Hill or Jones. Shalala v. Ill.
    Council on Long Term Care, Inc., 
    529 U.S. 1
    , 18 (2000) ("Th[e Supreme Court] does
    not normally overturn . . . earlier authority sub silentio . . . .").
    The Supreme Court warns "that courts should generally not depart from the
    usual practice under the Federal Rules on the basis of perceived policy concerns."
    
    Jones, 549 U.S. at 212
    . Despite this rule, the majority bases its decision on policy
    considerations: whether discovery and litigation would pressure Missouri's suppliers
    and agents to discontinue providing the drugs for executions. The question of whether
    discovery is appropriate or necessary is not currently before this court. Neither is the
    question of an injunction about the potential harm the State might suffer from
    disclosure of drug providers. The majority appears to impose a heightened pleading
    standard for fear that this suit would otherwise eventually require the disclosure of
    information which it fears would hamper Missouri's ability to carry out executions.
    This is not a reason to impose a heightened pleading standard in opposition to
    Supreme Court precedent and the Federal Rules of Civil Procedure.
    If policy concerns were relevant to the establishment of case-by-case pleading
    standards, policy concerns would weigh in favor of allowing this suit to proceed. It
    is troubling that under the majority's rule, the constitutionality of an execution method
    is determined not by the pain and suffering caused by that method, but rather by what
    resources a death-row inmate can garner to show an available alternative. If the
    manufacturers of safer drugs were willing to provide Missouri with execution drugs,
    Missouri's current execution protocol would likely be held unconstitutional. See
    
    Baze, 553 U.S. at 52
    (discussing requirements for a § 1983 suit when an alternative
    method of execution is readily available). In no other area do the private acts of third-
    parties so influence the determination of whether a government act is unconstitutional.
    Making it even more difficult for death-row inmates, they now must surpass these
    -39-
    barriers at the pleading stage, rather than at the summary judgment stage after the
    completion of discovery.
    Simply put, neither the Constitution nor the Federal Rules of Civil Procedure
    require a plaintiff challenging the constitutionality of government actions to
    simultaneously suggest a remedy–a remedy which cannot be to simply stop the
    unconstitutional activity. Such a heightened pleading standard has not been required
    in other constitutional cases, and should not be required here. Based on the foregoing
    reasons, I dissent from the imposition of any heightened pleading standards when
    death-row inmates challenge a state's method of execution.
    C
    Although I believe the pleading requirement imposed by the majority is an
    incorrect application of the law, I recognize my position in the minority and therefore
    find it prudent to comment on the resolution of this case. Even if the majority is
    correct in imposing this additional pleading requirement, it is improper to dismiss the
    death-row inmates' suit at this juncture. Rather, the matter should be remanded for the
    death-row inmates to amend their complaint because the death-row inmates' second
    amended complaint does, in fact, satisfy the pleading requirements previously
    suggested by the Eighth Circuit.
    In my view, in denying rehearing in the case of In re Lombardi the Eighth
    Circuit clarified that death-row inmates alleging an Eighth Amendment violation
    based on the method of execution must, in their pleadings, (1) "concede[] that 'other
    methods of lethal injection the Department could choose to use would be
    constitutional,'" In re Lombardi, 
    741 F.3d 903
    , 905 (8th Cir. 2014) (en banc) (quoting
    
    Hill, 547 U.S. at 580
    ); and (2) "allege[] 'that the challenged procedure presents a risk
    of pain the State can avoid while still being able to enforce the sentence ordering a
    lethal injection,'" 
    id. (quoting Hill
    , 547 U.S. at 581). In their second amended
    -40-
    complaint, the death-row inmates "concede that other methods of lethal injection the
    Department could choose to use would be constitutional." Zink v. Lombardi, No. 12-
    4209, Doc. 338 at 202 (W.D. Mo. Feb. 2, 2014). Thus, the death-row inmates pleaded
    exactly what In re Lombardi required of them: a concession "that other methods of
    lethal injection the Department could choose to use would be 
    constitutional." 741 F.3d at 905
    (internal quotation marks omitted).
    The Eighth Circuit now changes, once again, the pleading requirements for an
    Eighth Amendment claim. Because the death-row inmates complied with In re
    Lombardi, and because the Eighth Circuit is for the first time imposing a stricter
    pleading requirement, a remand is proper. The death-row inmates should have the
    opportunity to plead a named alternative method before the complaint is dismissed.
    However, in light of today's ruling dismissing the complaint, the death-row inmates,
    if they choose to do so, will have to settle for initiating new litigation in the district
    court and filing a complaint which complies with the newly-established pleading
    standards. For example, if the death-row inmates desire, the death-row inmates could
    propose as an available alternative an execution protocol using pentobarbital which
    was properly compounded at an FDA-approved compounding pharmacy, and has
    thereafter been tested for identity, potency, purity, and contamination.
    D
    The majority also extends the imposition of a heightened pleading requirement
    beyond the death-row inmates' Eighth Amendment claims. Without an explanation
    of this extension, the majority resolves the death-row inmates' medical needs claim
    "[f]or reasons discussed in Part II." The majority also dismisses the death-row
    inmates' due process claim at least in part based on the death-row inmates' failure to
    "plead[] a deprivation of rights under the Eighth Amendment." I disagree with any
    extension of the heightened pleading requirement, and dissent from these portions of
    the majority's opinion.
    -41-
    III
    The majority opinion establishes heightened pleading requirements for death-
    row inmates challenging a state's method of execution under the Eighth Amendment.
    This imposition is in opposition to governing Supreme Court precedent and the
    Federal Rules of Civil Procedure. In other words, the Eighth Circuit now prevents
    death-row inmates from truly accessing the federal courts: a death-row inmate cannot
    benefit from discovery and is prohibited from challenging even a truly unconscionable
    method of execution if no other methods are readily available and obvious at the
    pleading stage.
    The death-row inmates have established the risk of using alleged compounded
    pentobarbital to carry out an execution, and have conceded other forms of execution
    are constitutional. Therefore, I would reverse the district court, stay the executions
    of the death-row inmates pending resolution of the suit, and remand for the district
    court to conduct discovery in its usual and normal course of business.
    SHEPHERD, Circuit Judge, dissenting in part.
    In Lombardi, because the prisoners had not conceded that other methods of
    lethal injection which the state of Missouri could choose would be constitutional,
    “[w]e were not required to address whether alleging that the current method of
    execution creates a substantial risk of harm when compared to known and available
    alternatives, without specifying an alternative, would be sufficient to state a claim in
    light of Hill and Baze.” In re Lombardi, 
    741 F.3d 903
    , 905 (8th Cir. 2014). The
    court now holds, in Part II.B. of this opinion, that even with such a concession the
    prisoners must indeed identify an alternative method of execution that is feasible, can
    be readily implemented, and will significantly reduce a substantial risk of severe pain
    in order to state an Eighth Amendment claim. I cannot agree with this conclusion.
    -42-
    First, it is not necessary for the court to reach this issue. In Part II.A. of this
    opinion we explain that the second amended complaint’s Eighth Amendment
    challenge to Missouri’s method of execution by lethal injection fails to state a claim
    because it does not include the requisite plausible allegations that the lethal execution
    protocol creates a substantial risk of severe pain. So holding, we need not reach the
    issue of the sufficiency of the second amended complaint’s allegation of an alternative
    method of execution. See Raby v. Livingston, 
    600 F.3d 552
    , 560-61 (5th Cir. 2010)
    (“Because we find that Raby has failed to establish that the Texas lethal injection
    protocol creates a demonstrated risk of severe pain, we do not reach the second step
    of the Baze test, whether the risk created by the current protocol is substantial when
    compared to the known and available alternatives.”).
    Second, if in fact the issue is be addressed, I disagree substantively with the
    court’s holding. In Hill v. McDonough, the Supreme Court considered whether a
    prisoner’s Eighth Amendment challenge to Florida’s lethal-injection protocol could
    proceed as a § 1983 action or must proceed as a habeas action. 
    547 U.S. 573
    , 576
    (2006). In finding that the action could proceed under § 1983, the Court rejected the
    government’s contention that the prisoner must plead an alternative means of
    execution to state a § 1983 claim. 
    Id. at 582.
    The Hill Court noted that “[s]pecific
    pleading requirements are mandated by the Federal Rules of Civil Procedure, and not,
    as a general rule, through case-by-case determinations of the federal court.” 
    Id. (citing Swierkiewicz
    v. Sorema N.A., 
    534 U.S. 506
    , 512-14 (2002)).
    Lest there be any confusion about underpinnings of the holding, in its very next
    term, in Jones v. Bock, the Supreme Court explained, “[J]ust last Term, in Hill v.
    McDonough, we unanimously rejected a proposal that § 1983 suits challenging a
    method of execution must identify an acceptable alternative.” 
    519 U.S. 199
    , 213
    (2007) (internal citation omitted).
    -43-
    Reading Hill and Jones together, I cannot conclude that the Supreme Court has
    mandated a heightened pleading standard requiring identification of an alternative
    method of execution in this § 1983 action asserting an Eighth Amendment claim. The
    Supreme Court explicitly rejected such a requirement in Jones, and I take the Court
    to mean what it says. In Part II.B., this court attempts to confine Hill to its holding
    that an Eighth Amendment challenge to a lethal injection protocol may proceed under
    § 1983 action rather than a decision relating to the sufficiency of a complaint under
    the Federal Rules. In Jones, however, the Supreme Court addresses the adequacy of
    a complaint under Rule 8 and rejects court devised heightened pleading requirements.
    Finally, in Part II.B., the court identifies the risk that allowing protracted
    discovery could have the practical effect of thwarting the State’s ability to carry out
    any executions. Although I am cognizant of such a possibility, the Federal Rules of
    Civil Procedure govern the sufficiency of the second amended complaint rather than
    policy considerations. See 
    Jones, 549 U.S. at 212
    (“[C]ourts should generally not
    depart from the usual practice under the Federal Rules on the basis of perceived policy
    concerns.”).
    For the reasons set forth in Part II.A. of the court’s opinion, the second
    amended complaint’s Eighth Amendment challenge to Missouri’s lethal injection
    protocol must be dismissed because it does not include the requisite plausible
    allegations that the protocol creates the substantial risk of severe pain. However, I
    cannot agree with the court’s conclusion that the prisoners must also identify an
    alternative method of execution in the complaint.
    Accordingly, I join in all but Part II.B. of this opinion.
