BPC-157
Preclinical
Research chemical
Summary
Synthetic gastric pentadecapeptide studied for tissue repair, gut integrity, and soft-tissue recovery.
Categories
Healing & Recovery
Mechanism
Proposed actions include modulation of the nitric oxide system, upregulation of growth-factor signaling (including VEGFR2 pathways), stabilization of the gut barrier, and influence on the brain-gut axis. It may support angiogenesis and fibroblast activity in injury models.
Half-life
Short (hours); often dosed once or twice daily in research protocols
Routes
Subcutaneous injection; Oral
Legal / access
Not FDA-approved for human use. FDA has raised concerns about compounding certain bulk peptides including BPC-157. Often sold as a research chemical.
Key risks
- Generally described as well-tolerated in anecdotal reports
- Injection-site irritation
- Unknown long-term human safety profile
Common claims
- Faster soft-tissue recovery from training or injury
- Support for gut issues and leaky-gut narratives
- Joint comfort and systemic recovery when stacked with TB-500
