BPC-157 is a synthetic 15-residue peptide, Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val (GEPPPGKPADDAGLV), described by its discoverers as a fragment of a protein from human gastric juice. This BPC-157 peptide comes as 10 mg and 20 mg lyophilised vials, each size with its own lot certificate.

BPC stands for “body protection compound”. In the early 1990s Predrag Sikirić’s group at the University of Zagreb described BPC as a larger peptide isolated from human gastric juice and BPC-157 as a fully characterised 15-amino-acid fragment of it, which they proposed carries its activity. The peptide is linear with free ends and four prolines; the group’s papers call it the “stable gastric pentadecapeptide BPC 157”.
Almost all published BPC-157 research is animal work, most of it rat studies from that same group, across tendon, ligament, gut, wound and vascular models. In rats and dogs the intact peptide is short-lived, with an elimination half-life under 30 minutes, and is broken down quickly into small fragments. It is often discussed next to TB-500, an unrelated peptide; see TB-500 vs BPC-157.

Published human data are small and uncontrolled: a retrospective knee-pain series of 16 patients, a 12-patient pilot in interstitial cystitis and a two-person intravenous safety pilot, all from one US clinic group, with no placebo arm. Lee E, et al., 2021; Lee E, et al., 2024; Lee E, et al., 2025. A randomised phase 2 trial in hamstring strain was recruiting in October 2026 (NCT07437547).
BPC-157 is not a component of any approved drug. FDA placed it in its 503A compounding category 2 (substances that may present significant safety risks) on 29 September 2023; the page now lists it among substances nominated and then withdrawn. At its July 2026 Pharmacy Compounding Advisory Committee meeting FDA proposed that BPC-157 not be added to the compounding bulks list. WADA’s Prohibited List names it under non-approved substances. FDA compounding safety-risk list. Clean Peptide’s BPC-157 is a laboratory reference material only, not for human or veterinary use.
Every figure below is transcribed from the paperwork for this compound.
BPC-157 is a synthetic 15-residue peptide, GEPPPGKPADDAGLV, described by its Zagreb discoverers as a fragment of a protein (BPC, body protection compound) isolated from human gastric juice.
1419.5 g/mol for C62H98N16O22 (PubChem CID 9941957). The free base is CAS 137525-51-0; the acetate salt is CAS 216441-37-1.
Only in small uncontrolled reports from one US clinic group (16, 12 and 2 people) with no placebo arm. A 2025 systematic review found 35 preclinical studies and one clinical one. A randomised phase 2 trial was recruiting in October 2026.
No. It is not part of any approved drug. FDA placed it in its 503A category 2 in September 2023 and in July 2026 proposed not adding it to the compounding bulks list. WADA prohibits it in sport.
They are unrelated. BPC-157 is a 15-residue gastric-protein fragment; TB-500 is a 7-residue acetylated fragment of thymosin beta-4. They are often studied and sold together, as in the BPC-157 / TB-500 blend.
Each size has its own certificate, listed on this page with lot number, laboratory, test date, HPLC purity, measured content and identity: ILS Laboratories for the 10 mg lot and Accurate Test Labs for the 20 mg lot.
Each size ships against the certificate issued for its own fill — purity, identity and batch, on file before you buy.
