KPV vs BPC-157: What the Research Shows

KPV and BPC-157 side by side: what they are, how they are regulated and what is still unknown.

Where the research points

Summary of studies, not a recommendation

Consider KPV if…

  • you are tested in sport and want to avoid a WADA-prohibited substance: BPC-157 is prohibited by WADA at all times (check KPV's own status separately)[2]

Consider BPC-157 if…

  • you want any human reports (a small, uncontrolled report): 14 of 16 patients (87.5%) reported relief with BPC 157 alone or combined with thymosin beta-4 (TB4).[15]

What they have in common

  • Only animal or lab studies of KPV were found (e.g. mouse): KPV-treated mice recovered earlier and regained more body weight in DSS colitis.[3]
  • Caution on BPC-157 evidence from a systematic review: Only 1 of 36 included studies was clinical; 35 were preclinical.[16]
Neither is FDA approved for any use in people. BPC-157 is prohibited in tested sport (WADA). Status labels come from public FDA and WADA records; see the sources below.

WADAWADA status unclearKPV: This is not named on the 2026 list. The catch-all class S0 prohibits any drug with no approval anywhere for human use, so it would be banned if no health authority has approved it, but we have not verified that for this substance.Prohibited by WADA (S0)BPC-157 is named in S0 (non-approved substances), prohibited at all times, in and out of competition.
