    NIEMEYER, Circuit Judge:
    In his application for a writ of habeas corpus filed under 
    28 U.S.C. § 2254
    , Charles
    Vandross — who was convicted in a South Carolina state court for murder, burglary,
    kidnapping, and related crimes — claimed that his trial counsel’s performance was
    constitutionally deficient under the standard established in Strickland v. Washington, 
    466 U.S. 668
     (1984). He noted that his trial counsel failed to call any forensic experts to testify
    on his behalf and asserted that such failure was not a strategic decision but was made out
    of counsel’s ignorance of the availability of funding to pay experts. He asserted further
    that his post-conviction counsel’s performance was also constitutionally deficient in failing
    to demonstrate that his trial counsel’s deficiency was prejudicial. The district court granted
    summary judgment to the State because Vandross failed to show prejudice not only in the
    state post-conviction court but also in the district court.
    We granted a certificate of appealability on the ineffective-assistance issue and now
    affirm. Even though the district court did not restrict its review by considering only the
    state court record, as required in the circumstances, but instead considered an affidavit of
    a forensic expert that Vandross presented for the first time in the district court, we
    nonetheless agree with the district court’s conclusion that the expert failed to show
    prejudice with evidence or a proffer of evidence “of what a defensive forensic expert would
    have testified to and how that could have altered the trial.” The forensic expert only
    identified investigatory issues that he or another forensic expert could have explored and
    did not test or challenge any evidence actually presented to the jury so as to support a
    2
    conclusion that testimony from him or another forensic expert could have made a
    difference.
    I
    The proof against Vandross at his state trial in Greenwood County, South Carolina,
    consisted mostly of the testimony of his former girlfriend, JoAnn Suber Wilson, and
    forensic evidence that corroborated some of her testimony. Generally, Wilson testified that
    following an argument with Vandross, Vandross broke into her house, murdered the man
    whom Wilson was then with, and then kidnapped her at gunpoint.
    More particularly, Wilson testified that after she and Vandross began dating in July
    2003, Vandross moved into her house, and the two lived together on and off for the next
    12 to 14 months. Eventually, though, he moved into his own apartment nearby, but he kept
    a key to Wilson’s house. He also gave Wilson a key to his apartment. After an argument
    on October 31, 2004, Wilson asked Vandross to leave her house, and he did so, but he kept
    her key. Because she became scared of Vandross, she asked a prior boyfriend, Sanford
    Best, to stay with her in her house, and he agreed. The next day, on November 1, Vandross
    went to Wilson’s workplace, and the two exchanged keys. Two days later, on November
    3, Wilson received a call from a friend that prompted her that same day to seek a restraining
    order against Vandross. She received a no-trespassing notice. Later that day, when she
    and Best were watching her son’s ball game, she saw Vandross, and he just “stare[d]” at
    them.
    3
    During that night, after Wilson and Best had gone to sleep in the same bed, Wilson
    was awakened by Vandross’s hand over her mouth and a gun pointed to her head. Vandross
    warned her that she “better not scream.” As Wilson resisted, a tussle resulted, and
    Vandross threw Wilson violently to the floor, bruising her and causing bleeding from her
    nose and mouth. She stopped resisting only after Vandross threatened to “include [her]
    children in it.” When Vandross let Wilson use the bathroom after she had pleaded with
    him that she really needed to go, she took some of the blood from her wounds and attempted
    to write Vandross’s name on the bathroom wall. She explained that she did so because she
    believed that Vandross was going to kill her. Vandross then threw her some of her clothes
    to get dressed and a roll of duct tape that he had brought with him, instructing her to put
    the tape over her mouth. While she did so, she spit on the tape so that it would be loose
    and could be removed more easily. She also left pieces of tape in the bathroom as “clues.”
    When Vandross saw Wilson through the open door spitting on the tape, he wrapped the
    tape around her head “all the way down to [her] neck.” She could barely breathe, as only
    one nostril was left open. Vandross then pushed Wilson back through the bedroom into
    the living room, and as they passed through the bedroom, Wilson testified that “out of the
    corner of [her] eye,” she saw Best on the bed “with a pillow over his head.” Vandross
    grabbed Wilson’s car keys, led her through the back door, and put her into the driver’s seat
    of her car, while taking the passenger seat. He then instructed Wilson to drive, even though
    she was complaining about her restricted ability to do so with the duct tape wrapped about
    her face.
    4
    Following Vandross’s instructions, Wilson pulled the car into a church parking lot.
    But when they saw the lights on in two nearby houses, one of which was a parsonage,
    Vandross told Wilson, at gunpoint, to drive to a second church. After entering its parking
    lot, she attempted to run the car into a silver tank, but Vandross hit the brake and stopped
    the car. He grabbed the keys, put the car in park, and ripped the duct tape off of Wilson as
    he started “ranting and raving” about prior arguments during their relationship. It was now
    about 3:00 a.m. on November 4.          Vandross related details of their past, expressed
    jealousies, and stated that he loved her but she didn’t love him. He continued his
    monologue, stating, “My life is ruined, I’ve killed a man.” When Wilson insisted that she
    did love him and recalled how he had said that their “hugs [were] special,” she invited a
    hug from Vandross. He then pulled Wilson out of the car, hugged her, and started to quote
    scripture. She nonetheless started praying, believing still that he was about to kill her. As
    Vandross’s temperament thus flipped, he told Wilson that he would never hurt her. He
    “pulled the clip out of the gun,” put it in his pocket, and said, “Let’s get back in the car.”
    Observing that it was “5:50” and “time for the kids to get up,” he stated that he would take
    her back to the house if she promised to do certain things, including taking the children
    outside in time for the school bus and not telling the police. During this discourse, he
    observed that he expected to be sentenced to only “eight to ten years for this” because it
    was his “first offense.” When Wilson suggested that they call the police because Best
    might not be dead, Vandross replied, “Trust me, he’s dead.”
    Wilson drove them back to her house, and while still parked, he instructed her to
    take off her outer shirt, combed her hair with his fingers, and cleaned some of the blood
    5
    off of her face with saliva, as one would do for a child. Wilson then went inside, woke up
    her sons, and got them dressed. But while inside, she also called the police. She then took
    her boys out front to wait for the bus. Once she heard sirens, however, she and the boys
    ran to meet the police.
    Officer Chris Hammett testified that he found Vandross standing on Wilson’s back
    porch. Following Hammett’s command, Vandross handed over the unloaded gun, and the
    officer found the clip in Vandross’s pants pocket. Officer James Boggs testified that, inside
    the house, the bedroom TV was “very loud” and that Best was lying dead on the bed with
    a gunshot wound to his head. Wilson testified at trial that she had never heard the gunshot.
    To corroborate Wilson’s testimony, the State presented forensic evidence analyzing
    evidence collected from the scene by an evidence technician.
    The technician collected a gun residue kit from Vandross, and the subsequent test
    indicated that lead particles were on Vandross’s shirt but that there was no detectable
    amount of the other two chemicals necessary to classify those particles as gunshot residue.
    No tests were conducted for gun residue on Wilson.
    The State also conducted a series of DNA tests. A test of the gun recovered from
    Vandross did not reveal any DNA on the gun. Pieces of duct tape from Wilson’s car had
    Wilson’s DNA on them but not any blood or DNA from Vandross. Similarly, a test of the
    duct tape roll revealed Wilson’s DNA on it but not Vandross’s. Samples of blood taken
    from the bathroom belonged to Wilson. A test of Vandross’s pants had Wilson’s DNA on
    them.
    6
    A white shirt was recovered from the floor of Wilson’s car, which had red or brown
    stains on it, as well as a smudge that could have been a handprint. While the technician
    testified that he did not know if the shirt had been submitted to testing, a DNA analyst
    testified that a test of the shirt found blood belonging to Best.
    The technician found a stocking cap on the back porch of Wilson’s house, but it was
    never tested. He did not attempt to collect any fiber, hair, or fingerprint evidence in the
    house because Vandross was known to have been a recent resident.
    A firearms expert testified that the gun recovered from Vandross was the same gun
    that fired the bullet that killed Best, and the technician collected a shell casing from the
    floor next to the bed.
    A forensic pathologist analyzed Best’s gunshot wound and testified that the abraded
    skin around the hole indicated that the gun was against the skin when fired. He stated
    further that the gun taken from Vandross was consistent with the wound. Finally, he
    testified that based on his own experience of firing pistols, it “would not be unusual” for
    someone in the same room not to hear a gunshot when it is fired directly against the skin.
    During closing argument at trial, Vandross’s attorney highlighted the gaps in the
    forensic evidence, pointing out that testing did not identify any of Best’s DNA on
    Vandross’s hands, clothing, or gun. He similarly highlighted the absence of Vandross’s
    DNA on the duct tape. Finally, he argued that the shell casing’s location was not consistent
    with where Vandross would have stood to shoot Best.
    Following the jury’s guilty verdict, Vandross appealed, and the South Carolina
    Court of Appeals affirmed his conviction. Vandross then applied to the Greenwood County
    7
    Court for post-conviction relief (“PCR”), claiming, among other things, the ineffective
    assistance of his trial counsel in failing “to hire and interview or call to testify experts,”
    listing experts in eight distinct disciplines. He contended that his counsel’s ineffective
    assistance violated his rights under the Sixth Amendment, citing Strickland v. Washington,
    
    466 U.S. 668
     (1984). At the PCR hearing, Vandross’s trial counsel testified that he did not
    hire any experts to testify at trial or advise him because, even though he “thought it would
    be very beneficial to us,” he did not have the funds to do so and, he added, neither did
    Vandross. Vandross did not present any expert testimony at the PCR hearing to support
    his claim of prejudice resulting from this alleged ineffective assistance of counsel at trial
    because, as he testified, “we probably would have to pay for that” and “we could not
    guarantee what we would find.”
    The state PCR court denied Vandross’s PCR application on the merits, explaining,
    as to trial counsel’s failure to call any expert witnesses:
    Counsel testified he wanted to retain experts in this case, but Applicant had
    no funds with which to hire these experts. Counsel also testified he used the
    prior trial transcripts to fully cross-examine the witnesses, especially Wilson.
    Prejudice from trial counsel’s failure to call witnesses cannot be shown
    where the witnesses do not testify at post-conviction relief. An Applicant
    must produce the testimony of a favorable witness or otherwise offer the
    testimony in accordance with the rules of evidence at the PCR hearing in
    order to establish prejudice from the witness’ failure to testify at trial.
    Applicant produced no such testimony of any expert witnesses at the PCR
    hearing, and therefore cannot show any resulting prejudice.
    (Citations omitted).
    On July 24, 2017, the Supreme Court of South Carolina denied Vandross’s petition
    for a writ of certiorari to review the PCR court’s ruling.
    8
    Vandross then filed this § 2254 application in the district court on September 15,
    2017, making several claims, including that he received the ineffective assistance of
    counsel at trial “when trial counsel failed to obtain funding for expert witnesses.”
    Amplifying that claim in his application, he stated:
    Petitioner’s trial counsel never consulted or secured any experts for either of
    Petitioner’s murder trials because he did not know that he could secure
    funding for them. Given the State’s heavy reliance on forensic testimony,
    and the two prior [trials based on hung juries], counsel’s performance was
    objectively both deficient and prejudicial.
    Vandross asserted that his trial counsel did not make a strategic choice about the need for
    experts; indeed, his trial counsel conceded, when testifying at the PCR hearing, that experts
    would have been “very beneficial” to Vandross. Vandross argued further that the district
    court should not deny his application on the basis of the state’s PCR ruling because his
    counsel in that proceeding was also ineffective. He maintained that “the procedural
    default” in failing to show prejudice at his state PCR hearing should be excused because
    state PCR counsel was ineffective in failing to hire experts to show prejudice, relying on
    Martinez v. Ryan, 
    566 U.S. 1
    , 17 (2012) (holding that, in limited circumstances, cause to
    excuse procedural default might be established by ineffective counsel in state collateral
    proceedings).
    The district court approved funding for Vandross to retain a forensic expert to
    support his § 2254 application, and Vandross retained Dr. Rodger Morrison. Dr. Morrison
    submitted a two-page affidavit, which identified 14 investigatory issues that a forensic
    expert could have addressed at trial. He did not, however, test any evidence, concluding
    9
    only that if trial counsel had retained a forensic expert, “it would have undermined the
    integrity of the State’s case against Mr. Vandross.”
    By order dated July 20, 2018, the district court granted the State’s motion for
    summary judgment. It agreed with the state PCR court that Vandross failed to establish
    prejudice from his trial counsel’s alleged ineffective assistance because he offered no
    expert testimony at the PCR hearing to support his claim. The court concluded further that
    Dr. Morrison’s affidavit did not demonstrate prejudice because it “fail[ed] to offer any
    substantive testimony that would have served to challenge the evidence offered by the
    state” at trial.
    Vandross filed this appeal from the district court’s order, and on February 4, 2019,
    we granted a certificate of appealability as to his claim of ineffective assistance of trial
    counsel for failing to retain experts and present expert testimony at trial.
    II
    In his § 2254 application, Vandross claims that he received the ineffective assistance
    of counsel at trial “when trial counsel failed to obtain funding for expert witnesses.” He
    maintains that his counsel did not make a strategic choice about the need for experts;
    indeed, his counsel conceded that he believed experts would have been “very beneficial”
    to Vandross. His counsel explained that he did not retain experts because neither he nor
    Vandross could afford to pay for them. Counsel was apparently unaware of a South
    Carolina statute that provides funding to indigent defendants for exactly this purpose. See
    
    S.C. Code Ann. § 17-3-50
    (B) (authorizing up to “five hundred dollars” to pay for
    10
    investigation and experts to assist certain indigent defendants). Vandross asserts that such
    an elementary mistake of law constitutes deficient performance. See Hinton v. Alabama,
    
    571 U.S. 263
    , 273 (2014) (per curiam) (finding deficient performance where trial counsel’s
    failure to seek additional funds for an expert witness “was based not on any strategic choice
    but on a mistaken belief that available funding was capped”). He also asserts that this
    deficiency prejudiced him at trial because experts could have testified about evidentiary
    holes in the State’s case, which could have altered the ultimate outcome.
    But this is the same claim that Vandross presented to the state PCR court and that
    the state court resolved on the merits. Vandross claimed in his state PCR application that
    he received the ineffective assistance because his counsel failed “to hire and interview or
    call to testify experts” in numerous distinct disciplinary areas to counter the State’s
    evidence, including an “expert on guns,” a “doctor or blood expert,” a “handprint expert,”
    a “clothing expert,” and a “psychiatrist.” And he claimed that he “was prejudiced by
    counsel’s failure.” Finally, he argued that “in every instance of ineffective assistance of
    counsel heretofore described . . . his United States Constitutional rights were violated. The
    Sixth Amendment guarantees the right to effective assistance of counsel in criminal
    prosecutions,” citing Strickland.
    The PCR court considered Vandross’s claim on the merits, reciting each expert
    requested and the reasons why that expert was claimed to be relevant. But it also noted
    that “none of these ‘experts’ were present to testify on his behalf at the PCR hearing” to
    “show any resulting prejudice.” In denying relief, the PCR court applied federal law,
    noting that it required Vandross to show (1) that his “counsel’s performance was deficient,”
    11
    and (2) that his “counsel’s deficient performance . . . prejudiced Applicant such that ‘there
    is a reasonable probability that, but for counsel’s unprofessional errors, the result of the
    proceeding would have been different,’” quoting Cherry v. State, 
    386 S.E. 2d 624
    , 625
    (S.C. 1989) (quoting Strickland, 
    466 U.S. at 694
    ). In concluding that Vandross failed to
    meet his burden, the court held, among other things, that Vandross failed to prove the
    prejudice prong of Strickland, stating:
    Prejudice from trial counsel’s failure to call witnesses cannot be shown
    where the witnesses do not testify at post-conviction relief. Underwood v.
    State, 
    309 S.C. 560
    , 
    425 S.E.2d 20
     (1992); Bassett v. Thompson, 
    915 F.2d 932
     (4th Cir. 1990), cert. denied, 
    499 U.S. 982
     (1991). An Applicant must
    produce the testimony of a favorable witness or otherwise offer the testimony
    in accordance with the rules of evidence at the PCR hearing in order to
    establish prejudice from the witness’ failure to testify at trial. Bannister v.
    State, 
    333 S.C. 298
    , 
    509 S.E.2d 807
     (1998). Applicant produced no such
    testimony of any expert witnesses at the PCR hearing, and therefore cannot
    show any resulting prejudice.
    In short, the state PCR court decided on the merits the very same claim that Vandross set
    forth in his § 2254 application.
    While § 2254 authorizes federal courts to “entertain” an application for a writ of
    habeas corpus from a person in state custody “in violation of the Constitution or laws or
    treaties of the United States,” 
    28 U.S.C. § 2254
    (a), it provides nonetheless that such a
    habeas writ may not be granted “with respect to any claim that was adjudicated on the
    merits in state court proceedings,” subject to three exceptions: (1) a showing that the state
    court decision “was contrary to” federal law; (2) a showing that the state court decision
    “involved an unreasonable application of” federal law; or (3) the state court decision “was
    based on an unreasonable determination of the facts” in light of the record before the state
    12
    court, 
    id.
     § 2254(d) (emphasis added); Harrington v. Richter, 
    562 U.S. 86
    , 100 (2011).
    Therefore, because the state PCR court adjudicated Vandross’s ineffective-assistance claim
    on the merits, Vandross must, to obtain federal review of that claim, show one of the three
    exceptions to the § 2254(d) bar — specifically, as applicable here, that the state PCR
    decision “involved an unreasonable application of” federal law. This he has not attempted
    to do, nor could he.
    The state PCR court correctly recited the requirements of Strickland and correctly
    applied those requirements to the facts in the record. In doing so, it also concluded
    correctly that no evidence was presented or offered to show prejudice in that any of the
    forensic evidence presented by the State at trial was flawed. While Vandross did point out
    various gaps in the State’s evidence, he highlighted those gaps to the jury. Moreover, he
    did not offer or present any evidence to the state PCR court that would have filled the gaps
    such that it would show a reasonable probability of a change in the result. Simply,
    Vandross has not shown that the PCR court’s decision was an unreasonable application of
    Strickland as is necessary to show an exception to the § 2254(d) bar to review a state PCR
    decision resolving a claim on the merits.
    III
    Rather than attempting to demonstrate that the PCR court’s decision was an
    unreasonable application of federal law, Vandross argues that his failure to show prejudice
    at the state PCR hearing was the result of the ineffective assistance of counsel at that
    hearing. Like his trial counsel, his state PCR counsel failed to present any expert testimony,
    13
    this time as needed to show prejudice from his trial counsel’s failure to do so. Because of
    that deficiency, Vandross argues, he should be excused from demonstrating that the PCR
    court unreasonably applied federal law, and he requests instead that the federal court
    perform collateral review of the issue. In making his argument, he recognizes the general
    rule that because he was not constitutionally entitled to counsel during his state post-
    conviction proceedings, he “cannot claim constitutionally ineffective assistance of counsel
    in such proceedings.” Coleman v. Thompson, 
    501 U.S. 722
    , 752 (1991). He instead seeks
    to justify federal review by calling his counsel’s deficiency in the state PCR proceeding a
    procedural default that justifies application of the narrow exception provided by Martinez
    v. Ryan, 
    566 U.S. 1
     (2012). In Martinez, the Court held that a federal court may review a
    procedurally defaulted ineffective-assistance claim when (1) the state PCR court is the first
    occasion for raising the claim, (2) the petitioner’s counsel provided ineffective assistance
    in the PCR court, and (3) it is likely that no state court will hear the prisoner’s claim. 
    Id. at 18
    . To support federal review justified by the Martinez exception, Vandross requested
    funding from the district court to retain an expert for the federal proceeding — a request
    the court granted — and then presented the affidavit of Dr. Morrison to show prejudice
    resulting from his trial counsel’s deficiency. The district court considered the affidavit
    over the objection of the State in resolving Vandross’s § 2254 application.
    Vandross’s argument to excuse his failure to show prejudice at the state PCR
    hearing raises two issues. Can Vandross supplement the state court record in the federal
    court on the ground that his state PCR counsel was deficient, relying on Martinez? And
    14
    does the record, even when so supplemented, sufficiently support a showing of prejudice?
    We address these in order.
    A
    As a general rule, our review under § 2254(d) “is limited to the record that was
    before the state court that adjudicated the claim on the merits.” Cullen v. Pinholster, 
    563 U.S. 170
    , 181 (2011); see also Moore v. Stirling, 
    952 F.3d 174
    , 181 (4th Cir. 2020). This
    rule flows directly from the text of § 2254, which “focuses on what a state court knew and
    did.” Pinholster, 
    563 U.S. at 182
    .
    Vandross nonetheless insists that Dr. Morrison’s affidavit may be considered
    because his failure to present evidence of prejudice at his state PCR hearing was itself the
    product of the ineffective assistance of his state PCR counsel. In making this argument, he
    seeks to apply cases involving the doctrine of procedural default, analogizing his PCR
    counsel’s failure to a default. Normally, if an applicant does not present a claim to a state
    court and that court does not have an opportunity to consider it, review by a federal court
    is barred because the claim is procedurally defaulted. See Coleman, 
    501 U.S. at
    731–32.
    But, as Vandross correctly argues, the Supreme Court has recognized a “narrow exception”
    to that rule in Martinez, 
    566 U.S. at 9
    . As the Martinez Court stated, a federal court may
    review a “substantial” ineffective assistance of counsel claim, notwithstanding procedural
    default, when state law required that the claim be raised in the state “initial-review
    collateral proceeding” and, in that initial proceeding, “there was no counsel or counsel in
    15
    that proceeding was ineffective.” 
    566 U.S. at 17
    ; see also Trevino v. Thaler, 
    569 U.S. 413
    ,
    423 (2013) (identifying the four elements necessary to apply the Martinez exception).
    In effect, Vandross requests that we carry the Martinez exception to procedural
    default over to this case to provide an exception to the distinct rule that our review under
    § 2254 “is limited to the record that was before the state court.” Pinholster, 
    563 U.S. at 181
    . This request, however, is foreclosed.
    We have already held on more than one occasion that Martinez, which authorizes a
    federal court to consider a new claim that was procedurally defaulted, does not provide a
    similar exception for new evidence supporting a claim that was in fact presented in state
    court. See, e.g., Gray v. Zook, 
    806 F.3d 783
    , 789 (4th Cir. 2015) (“[I]f claims are not
    procedurally defaulted — that is, they were properly presented to the state court — then
    Martinez does not apply”). Other courts of appeals have uniformly reached the same
    conclusion. See, e.g., Escamilla v. Stephens, 
    749 F.3d 380
    , 395 (5th Cir. 2014) (“[O]nce a
    claim is considered and denied on the merits by the state habeas court, Martinez is
    inapplicable, and may not function as an exception to Pinholster’s rule that bars a federal
    habeas court from considering evidence not presented to the state habeas court”); Moore v.
    Mitchell, 
    708 F.3d 760
    , 785 (6th Cir. 2013) (“[Applicant] is not asking that we afford a
    Martinez-like review of a procedurally defaulted claim, but rather that we turn Martinez
    into a route to circumvent Pinholster”); Floyd v. Filson, 
    949 F.3d 1128
    , 1147–48 (9th Cir.
    2020) (same).
    In Gray, we held that, just like here, a federal court deciding a § 2254 claim may
    not consider an expert affidavit submitted to the district court after the applicant failed
    16
    previously to submit such evidence to the state court in order to prove that trial counsel’s
    failure to call expert witnesses prejudiced the applicant’s trial. Gray, 806 F.3d at 798–99.
    That rule, though, applies only when the federal habeas claim is “fundamentally the same”
    as the claim presented to the state court. Moore, 952 F.3d at 182. By contrast, in limited
    circumstances, “new evidence [can] ‘fundamentally alter’ the ‘substance’ of the claim so
    as to make the claim a new one” that was not presented to the state court. Id. at 182–83
    (cleaned up) (quoting Vasquez v. Hillery, 
    474 U.S. 254
    , 260 (1986)). But that does not
    occur where the new evidence does not “change the heart of the claim” but instead “merely
    strengthens the evidence presented in the state PCR hearing.” Id. at 184; see also Gray,
    806 F.3d at 799 (recognizing “that a petitioner may not support a claim in state court with
    mere conjecture and subsequently provide the necessary evidentiary support for the claim
    on federal habeas review”).
    In this case, Vandross did not procedurally default his ineffective-assistance claim
    before the state PCR court. Rather, he attempted to present it fully, arguing both his
    counsel’s deficiency and resulting prejudice. He simply sought, in the federal court, to
    supplement the evidence in support of that claim in order to better show prejudice. Thus,
    while Dr. Morrison’s affidavit might have strengthened Vandross’s ineffective-assistance
    claim, it did not “fundamentally alter” it. Gray, 806 F.3d at 799.
    Accordingly, our review is limited to the state PCR court’s record, and the district
    court’s consideration of Dr. Morrison’s affidavit was error. On that record, Vandross’s
    § 2254 application must be denied, as shown above. Nonetheless, the district court’s
    17
    conclusions about the substance of Dr. Morrison’s affidavit were completely valid, and we
    affirm on that basis also.
    B
    Vandross relies almost exclusively on Dr. Morrison’s affidavit to establish in federal
    court that his trial counsel’s deficient performance resulted in prejudice. He argues that it
    shows that his trial counsel never subjected Wilson’s account “to scientific scrutiny” and
    that there is a reasonable probability that doing so would have resulted in a different
    outcome.
    In his affidavit, Dr. Morrison states that “either I, or another forensic investigator,
    could have assisted trial counsel in challenging the forensic evidence in this case. In my
    opinion, law enforcement did not undertake a very thorough investigation, and I (or another
    forensic investigator) could have assisted trial counsel in bring[ing] this to the jury’s
    attention.” (Emphasis added). He then lists 14 distinct issues that could have been
    challenged at trial or could have been investigated further. He concludes, “Had trial
    counsel or PCR retained counsel [retained me or another forensic investigator] for purposes
    of challenging the forensic science testimony and the lack of physical evidence in this case,
    I believe it would have undermined the integrity of the State’s case against Mr. Vandross.”
    Remarkably, Dr. Morrison did not himself test, or have some other expert test, any
    of the relevant evidence. He did not even use his expertise to speculate as to what such
    testing would have found. Instead, he simply put forth a menu of options that a forensic
    expert could have explored in greater depth. Yet, from the substance of Dr. Morrison’s
    18
    affidavit, Vandross reasons that if an expert had so explored the list of options, the expert
    would have uncovered some form of evidence that may well have altered the jury’s verdict.
    But he has pointed to nothing specific.
    More is required. When a petitioner’s ineffective assistance of counsel claim rests
    on trial counsel’s failure to call particular witnesses, expert or otherwise, we require “a
    specific proffer . . . as to what an expert witness would have testified.” Goins v. Warden,
    Perry Corr. Inst., 576 F. App’x 167, 173 (4th Cir. 2014) (per curiam). A petitioner’s failure
    to do so “reduces any claim of prejudice to mere speculation and is fatal to his claim.” Id.
    (emphasis added); see also Bassette v. Thompson, 
    915 F.2d 932
    , 940 (4th Cir. 1990) (“The
    great failing of the appellant on his claim that other evidence should have been presented
    during the sentencing phase of his trial is the absence of a proffer of testimony from a
    witness or witnesses he claims his attorney should have called”); Beaver v. Thompson, 
    93 F.3d 1186
    , 1195 (4th Cir. 1996) (“[A]n allegation of inadequate investigation does not
    warrant habeas relief absent a proffer of what favorable evidence or testimony would have
    been produced”).
    The South Carolina courts require the same. See Bannister v. State, 
    509 S.E.2d 807
    ,
    809 (S.C. 1998) (“This Court has repeatedly held a PCR applicant must produce the
    testimony of a favorable witness or otherwise offer the testimony in accordance with the
    rules of evidence at the PCR hearing in order to establish prejudice from the witness’ failure
    to testify at trial”); Porter v. State, 
    629 S.E.2d 353
    , 358 (S.C. 2006), abrogated on other
    grounds by Smalls v. State, 
    810 S.E.2d 836
     (S.C. 2018) (“Mere speculation of what a
    witness’ testimony may be is insufficient to satisfy the burden of showing prejudice in a
    19
    petition for PCR”); Clark v. State, 
    434 S.E.2d 266
    , 267 (S.C. 1993) (“[P]ure conjecture”
    about how an expert witness would testify is not sufficient “to establish the result would
    probably change if a new trial is had”).
    Without proffering any evidence of what an expert would have concluded, Dr.
    Morrison’s affidavit suffers from what these cases describe as mere speculation. The
    affidavit identifies only where a forensic expert could have looked for exculpatory
    evidence, but it failed to present that exculpatory evidence — or even proof that it exists
    — to establish prejudice. In short, Dr. Morrison’s affidavit, even if properly considered,
    would not have helped Vandross’s claim, as the district court concluded.
    *      *       *
    We conclude that Vandross has failed to establish that the state PCR court’s decision
    involved an unreasonable application of federal law when it concluded that Vandross failed
    to prove the requisite prejudice for his ineffective assistance of counsel claim and therefore
    that the district court did not err in denying his § 2254 application.
