Most available support is preclinical, mechanistic or anecdotal. Human efficacy and long-term safety are not established.
Overview
BPC-157 (Body Protection Compound 157) is a synthetic 15-amino-acid peptide derived from a protein found in gastric juice. It is one of the most-discussed 'research peptides' online, largely for its studied effects on soft-tissue and gut healing in animal models.
How It's Thought to Work
Preclinical research suggests BPC-157 may promote angiogenesis (new blood-vessel formation) and modulate growth-factor and nitric-oxide pathways involved in tissue repair. The exact mechanisms in humans are not established.
What the Research Says
The large majority of BPC-157 evidence comes from rodent studies looking at tendon, ligament, muscle, and gastrointestinal healing. Human clinical trial data is very limited. Reports of benefit are largely preclinical or anecdotal.

Regulatory & Legal Status
Not approved by the FDA for human use. In 2023–2025 it drew regulatory attention as a compounded and 'research-only' product. Widely sold as a research chemical; legality and quality vary.
Safety Considerations
Human safety data is limited. Because most products are sold as research chemicals, purity and dosing are unregulated. Discuss any use with a qualified clinician.
