A synthetic 15-amino-acid peptide studied mainly in animals for tissue and gut healing. Human evidence is thin and its legal status is mid-review.
BPC-157 is a synthetic pentadecapeptide whose sequence comes from a larger protein found in human gastric juice. It does not occur in the body in this form. Interest in it comes almost entirely from laboratory and animal studies, many from a single research group in Croatia, reporting faster healing of tendon, ligament, muscle and gut injuries in rodents.
FDA placed BPC-157 in Category 2 of its 503A bulk-substance list in 2023, citing possible immunogenicity and impurity risks. It was removed from Category 2 effective April 23, 2026 after its nominations were withdrawn, which did not make it eligible for compounding. On July 23, 2026 the Pharmacy Compounding Advisory Committee voted 8–6 (one abstention) to recommend adding it to the 503A bulks list, reviewed for ulcerative colitis. FDA staff had recommended against inclusion, and the vote is non-binding. BPC-157 is not an FDA-approved drug and is not a lawful dietary supplement ingredient.
Status reflects public FDA actions and reporting as of October 8, 2026. An advisory committee vote is a recommendation, not an FDA decision, and inclusion on a compounding list is not FDA approval.
The animal literature is large; the human literature is not. A 2025 review of BPC-157 research found the evidence dominated by preclinical work, with only a handful of small human reports and no completed large randomized trial. Animal results often fail to carry over to people, so the honest summary is that benefit in humans is unproven, not that it is disproven.
nnng.com does not publish doses, cycles or protocols for peptides. For approved drugs, the dose comes from the FDA-approved prescribing information and your prescriber. For unapproved compounds there is no established human dose, and numbers that circulate online are usually extrapolated from animal studies or written by sellers. If a clinician has already prescribed a dose, our reconstitution calculator converts that prescribed amount into syringe units. It is arithmetic only and does not suggest a dose.
