BPC 157 peptide,
explained in depth.
A complete research library on BPC-157 — the synthetic pentadecapeptide derived from Body Protection Compound that has become the most-discussed healing peptide of the 2020s. Real mechanism of action, published dosing protocols, side effect data, and the regulatory history behind the most-researched fragment in the peptide world.
What is BPC 157 peptide?
BPC-157 is a synthetic 15-amino-acid peptide derived from a protein found in human gastric juice called Body Protection Compound. It was first isolated and characterized at the University of Zagreb, Croatia, by Professor Predrag Sikirić's research group beginning in the 1990s. The peptide sequence is Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val. Preclinical research has examined its role in angiogenesis, tissue repair, gut healing, and neuroprotection. Despite thousands of citations in animal studies, BPC-157 remains unapproved for human use by any regulatory agency worldwide.

| Fact | Detail |
|---|---|
| Origin | A synthetic 15-amino-acid (pentadecapeptide) fragment of Body Protection Compound, a protein isolated from human gastric juice. Sequence: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val. Molecular formula C62H98N16O22, molecular weight 1419.55 g/mol. |
| Researcher of record | Characterized and advanced by Predrag Sikirić's group at the University of Zagreb, Croatia, beginning in the 1990s. The overwhelming majority of published BPC-157 research originates from this lab. |
| Mechanism | Promotes angiogenesis and tissue repair through activation of the VEGFR2, nitric oxide, FAK-paxillin, JAK-2, Egr-1, and ERK1/2 signaling pathways. Also modulates dopamine, serotonin, and prostaglandin systems in rodent models. |
| Clinical status | Thousands of preclinical studies, almost entirely in rats and mice. One Phase I human trial (42 volunteers) was completed in 2015 but results were never published. Small pilot studies in humans for interstitial cystitis (2024) and IV infusion safety (2025) have since appeared but remain uncontrolled. |
| Regulatory status | Not FDA-approved for any indication. Placed on the FDA's Category 2 list of bulk drug substances that may present significant safety risks in compounding. Classified S0 (Non-Approved Substances) on the WADA Prohibited List since 2022. Listed on the U.S. Department of Defense Prohibited Dietary Supplement Ingredients List. |
