Mechanism of Action
BPC-157 (Body Protection Compound-157) is a pentadecapeptide consisting of 15 amino acids, isolated from a protective protein found in human gastric juice. While most research has been conducted in animal models, clinical observations demonstrate a broad range of regenerative effects.
Key mechanisms include:
- Growth hormone receptor upregulation — BPC-157 sensitises tissues to endogenous growth hormone, amplifying local anabolic signalling
- VEGF stimulation — increases vascular endothelial growth factor, accelerating new capillary formation in damaged tissue
- Nitric oxide (NO) modulation — regulates vascular tone and the inflammatory response
- FAK-paxillin pathway activation — accelerates fibroblast migration to the injury site
- Gastroprotection — protects gastric mucosa and restores intestinal barrier integrity in inflammatory bowel conditions []
Administration
Injectable protocol (systemic effect): Subcutaneous injections into the fat fold near the injury site. Most practitioners use 250–500 mcg twice daily for 4–6 weeks.
Oral dosing (for gastrointestinal issues): For IBS, ulcers, and mucosal inflammation — 250–500 mcg orally on an empty stomach. The peptide is resistant to breakdown in the gastric environment. []
Tissue Repair: Key Research
In a rat Achilles tendon rupture study, the BPC-157 group showed significantly faster restoration of collagen structure compared to controls. []
