From the Research

BPC-157 (Body Protection Compound) is a synthetic peptide derived from a protective protein found in gastric juice, specifically a 15-amino acid sequence that has been isolated and synthesized based on a larger protective protein found in the digestive system, as reported in the most recent study 1. The peptide was originally discovered and isolated by researchers in the 1990s who were studying gastric juice components with protective properties.

  • BPC-157 is not naturally occurring in this exact form in the body;
  • it is a laboratory-created fragment of the naturally occurring body protection compound (BPC) that is present in human gastric juice. Since BPC-157 is synthetic, it is produced in laboratories through chemical synthesis processes rather than being extracted directly from natural sources.
  • This synthetic origin allows for standardized production and purity control,
  • though it also means that BPC-157 is not classified as a natural supplement. The peptide has gained attention for its potential healing properties, particularly related to tissue repair and gastrointestinal protection,
  • as demonstrated in various studies, including those on wound healing 2 and brain-gut axis interaction 3, though it remains primarily an experimental compound not approved by major regulatory agencies for medical use, as noted in the most recent review 1.
