What Is BPC-157? A Quick Research Overview
Written by NorthPeptide Research Team | Reviewed March 20, 2026
BPC-157, or Body Protection Compound-157, is a synthetic pentadecapeptide consisting of 15 amino acids. It is derived from a protective protein naturally found in human gastric juice and has become one of the most extensively studied peptides in tissue repair research.
What Is BPC-157 and Where Does It Come From?
BPC-157 is a partial sequence of the body protection compound (BPC) isolated from human gastric juice. Unlike many research peptides, BPC-157 is stable in human gastric juice — a property that distinguishes it from most peptides, which degrade rapidly in acidic environments. Its sequence (Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val) has no known homology with any other known peptide or protein.
The peptide was first characterized by researchers studying the protective factors in gastric fluid, and subsequent studies expanded into its effects on tendons, ligaments, muscle, the nervous system, and the gastrointestinal tract.
What makes BPC-157 unique among research peptides is its broad range of studied effects. Most peptides target a single receptor or pathway. BPC-157 appears to interact with multiple systems, including the nitric oxide (NO) system, the FAK-paxillin pathway, and the growth hormone receptor pathway (PMID: 29776955).

Key Research Highlights
Tissue Repair: Multiple animal studies have demonstrated BPC-157’s effects on tendon, ligament, muscle, and bone healing. A 2018 systematic review found consistent evidence of accelerated tendon-to-bone healing in rat models (PMID: 29776955).
Gastrointestinal Protection: BPC-157 has shown cytoprotective effects in models of gastric ulcers, inflammatory bowel conditions, and NSAID-induced damage. Research indicates it promotes angiogenesis and granulation tissue formation in gut mucosa (PMID: 27847282).
Nitric Oxide System: BPC-157 appears to modulate the NO system, which plays a role in blood vessel formation, blood pressure regulation, and tissue repair. This interaction may explain its broad range of observed effects across different tissue types.
Neuroprotective Properties: Emerging research suggests BPC-157 may have effects on the central and peripheral nervous system, including studies on nerve crush injuries and dopaminergic system modulation.
Stability: Unlike most peptides, BPC-157 remains stable in gastric juice, making it an unusual subject for oral administration studies in animal models — most peptides require injection to avoid degradation.
