BPC-157: Research Overview & Protocol Guide

BPC-157 (Body Protection Compound-157) is a pentadecapeptide consisting of 15 amino acids, derived from a partial sequence of human gastric juice. It was first identified by researchers studying the protective properties of gastric proteins and has since become one of the most widely studied tissue repair peptides.

BPC-157 works through multiple pathways: upregulating growth factor expression (VEGF, EGF), modulating nitric oxide signaling, promoting angiogenesis at injury sites, and influencing the FAK-paxillin pathway involved in cell migration. This multi-modal mechanism explains its broad tissue-protective properties.

Over 100 published studies demonstrate BPC-157's effects in models of tendon, ligament, muscle, and bone healing; gastrointestinal protection; neuroprotection; and vascular repair. Most studies use doses of 10mcg/kg to 10mg/kg administered systemically or locally.

BPC-157 is frequently studied in combination with TB-500 (Thymosin Beta-4 fragment) and GHK-Cu. The BPC-157/TB-500 stack is the most popular tissue repair research protocol, with complementary mechanisms — BPC-157 for local repair and TB-500 for systemic tissue regeneration.
