Stable gastric pentadecapeptide BPC 157, composed of 15 amino acids, is a partial sequence of body protection compound that is resistant to enzymatic digestion in human gastric juice.

BPC-157
In vitroHow it works
A 15-amino-acid sequence derived from human gastric juice. In animal models it promotes blood vessel formation (VEGF-mediated angiogenesis) and speeds tendon, muscle, and ligament repair. The human evidence is a few small uncontrolled studies (2 to 16 people), and no controlled injury trial has reported results. 544 published studies sounds like a lot. 543 of them were in rats. The cancer-risk question is live: the same mechanism that drives healing — growing new blood vessels — could, in theory, also feed tumour growth. Nobody has ruled that out.
Key studies
Given BPC-157's angiogenic and proliferative properties documented in animal models, its potential to promote tumour growth cannot be excluded. Human safety data is absent.
Safety
WADA Prohibited List 2026. DoD OPSS advisory flags it as unsafe for military use. Long-term human safety data does not exist. The angiogenic mechanism that aids healing could theoretically promote tumour growth — this is the central safety unknown.
Frequently asked
What is BPC-157?
BPC-157 is a fifteen-amino-acid peptide, a partial sequence of body protection compound, a protein from gastric juice. In animal studies it appears to promote angiogenesis and activate the nitric-oxide pathway; its primary research group frames the effect as cytoprotection, not tumour induction. Human mechanistic data doesn't exist yet.
Is BPC-157 approved by the FDA?
No. BPC-157 has no FDA-approved drug application. In July 2026 an FDA advisory committee recommended adding it to the 503A Bulk Drug Substances List for pharmacy compounding, but that is not an approval. Outside that process, it's sold widely as a research chemical, not as an approved medicine.
Did the July 2026 PCAC vote approve BPC-157?
No. PCAC is an advisory committee, so its vote isn't an approval. On July 23, 2026, it recommended inclusion of BPC-157 on the 503A Bulk Drug Substances List for pharmacy compounding. The FDA makes the actual rulemaking decision, and FDA final action is pending.
Is BPC-157 banned for athletes?
Yes. BPC-157 sits on WADA's prohibited-at-all-times list, since it has no FDA-approved therapeutic use. Athletes subject to WADA testing should treat it as banned both in and out of competition, independent of how the FDA's compounding review turns out.
