What it is — A 15-amino-acid sequence derived from a protective protein found in human gastric juice — the most-studied "body protection compound" in tissue research. Why it's studied — BPC-157 upregulates VEGFR2, the receptor that drives new blood vessel formation, and modulates the nitric oxide system at injury sites. Two decades of animal research have made it one of the most consistently reproducible compounds in regenerative science. Key research findings

• 50–72% acceleration in tendon healing rates (Sikiric et al., rat Achilles transection model)

• Significant gut lining repair documented in inflammatory bowel models

• Demonstrated angiogenesis via VEGFR2 upregulation across multiple tissue types
