BPC-157
aka Body Protection Compound 157, PL14736
Education only. Many compounds discussed are research chemicals not approved for human use in the US. This is not medical advice — consult a licensed physician.
What it is
A 15-amino-acid sequence derived from a protein in human gastric juice. Studied for tendon, ligament, and gut healing. No human RCTs published — all trial data is animal model.
How it works
Animal studies suggest it promotes angiogenesis (new blood vessel growth), modulates the nitric oxide system, and accelerates wound healing in tendon and gut tissue.
What the research says
Robust animal data on tendon repair, gut ulcer healing, and angiogenesis. Zero published human RCTs — all human use is anecdotal.
