BPC-157

What is BPC-157?

BPC-157 is a synthetic 15-amino-acid peptide modeled after a protective gastric protein fragment. It is best understood as an investigational repair peptide: the strongest case is not that it numbs pain, boosts performance directly, or replaces rehab, but that it may accelerate tissue repair signaling in tendon, ligament, muscle, gut mucosa, wounds, and nerve-injury models.

From the BioHarmony report, reviewed 2026-09-08.

How it is thought to work

Nitric oxide and eNOS signaling, VEGFR2-linked angiogenesis, growth-hormone receptor expression in tendon fibroblasts, prostaglandin modulation, and dopamine and serotonin system stabilization

Safety watch-outs

• Injection-site infection
• Rapidly worsening swelling or pain
