BPC-157 (Body Protection Compound-157) is a synthetic research peptide composed of 15 amino acids and modeled after a naturally occurring compound found in gastric juice. When used orally in research settings, it is studied for its potential interaction with digestive stability, cellular protection, angiogenesis, and tissue repair pathways. Research suggests its activity may involve nitric oxide signaling, growth factor regulation, and extracellular matrix support—making it of interest in studies focused on systemic recovery and cellular resilience under stress.
