BPC-157
Body Protection Compound-157
15-amino acid peptide derived from human gastric juice. Promotes tissue repair, gut healing, and angiogenesis. Among the most-researched repair peptides available.
Mechanism of action
Activates VEGF and EGF growth factor pathways, promotes angiogenesis (new blood vessel formation), upregulates nitric oxide synthesis, and modulates the GABAergic system. Accelerates collagen synthesis and tendon-to-bone healing by stimulating tendon fibroblasts.
Effects in the body
BPC-157 acts as a master repair signal throughout the body. It accelerates healing in tendons, ligaments, muscles, and gut lining. Uniquely, it shows systemic effects even when taken orally — one of the few peptides where oral administration reaches therapeutic targets for gut-specific research.
Pros & cons (from the literature)
- Strong tendon and ligament repair data in preclinical models
- Gut healing studied in IBD and leaky gut animal models
- Anti-inflammatory and neuroprotective properties
- Oral AND injectable administration both studied
- Extremely well-tolerated in 300+ animal studies
- No completed Phase III human RCTs
- Theoretical cancer promotion via angiogenesis
- Gray-market purity varies widely (60–85% common vs 98%+ pharmaceutical grade)
- Optimal human dosing not established
- Long-term human safety unknown
