## What is BPC-157?

- Body Protection Compound-157, a synthetic 15-amino-acid peptide derived from a gastric juice protein; acts on angiogenesis (VEGFR2), nitric oxide (Akt-eNOS) and FAK-paxillin pathways; not FDA-approved, placed in FDA compounding Category 2 (safety concerns) in 2023 and banned in professional sport.
