BPC-157 (Body Protection Compound 157) is a synthetic 15-amino-acid peptide derived from a protein found in human gastric juice (Sikiric 2016 review). It is covered in the peptide library alongside related compounds.
Most BPC-157 research is in rats. In a rat model of Achilles tendon detachment (Krivic 2006), BPC-157 improved measures of tendon healing. In people, the strongest evidence recorded in the evidence dataset is small human studies. Three small uncontrolled human reports only: a 2-person intravenous safety pilot, a 12-patient interstitial cystitis pilot and a 16-patient retrospective knee-pain survey. No completed human randomised trial and no registered trial with results were found.
