BPC-157 (Body Protection Compound 157) is a synthetic pentadecapeptide consisting of 15 amino acids, derived from a protective protein found in human gastric juice. It is one of the most extensively studied repair peptides in preclinical research, with a broad range of regenerative effects documented across multiple tissue types including tendons, ligaments, muscles, bone, and gastrointestinal mucosa. BPC-157 appears to upregulate growth factor signaling (including VEGF and EGF pathways), promote angiogenesis, and modulate nitric oxide production. Research also points to systemic anti-inflammatory effects and potential neuroprotective properties, making it a uniquely versatile repair compound.
