What is BPC-157? A Complete Research Peptide Guide
BPC-157 is a 15-amino-acid research peptide derived from a gastric protein — here's the complete science-backed breakdown.
What is BPC-157?
BPC-157, short for Body Protective Compound-157, is a synthetic pentadecapeptide derived from a protective protein originally isolated in human gastric juice. It has become one of the most extensively studied research peptides in preclinical wound healing and gastrointestinal science.
Unlike naturally occurring signaling peptides that degrade rapidly, BPC-157 is stable in gastric acid, which is why it appears in oral, intraperitoneal and subcutaneous research protocols alike.
How does BPC-157 work?
BPC-157 is proposed to act through upregulation of VEGFR2 signaling, endothelial nitric oxide synthase (eNOS) activity and modulation of the growth-hormone receptor axis. Rodent studies show increased microvascular sprouting and restored blood flow in ischemic tissue.
It also normalizes gastric and intestinal mucosal integrity through NO-dependent pathways, and reduces pro-inflammatory cytokines in soft-tissue injury models.
Research applications
BPC-157 is a workhorse peptide in tendon and ligament repair studies, gut permeability research, cardiac ischemia-reperfusion models and neuroprotection screens. It is frequently paired with TB-500 (Thymosin Beta-4) — a combination available at Peptana as the Wolverine Blend.
Where to buy BPC-157 for research
