BPC-157 (Body Protection Compound-157) is a synthetic 15-amino-acid peptide best known for its proposed tissue-healing and anti-inflammatory effects.

Most of the impressive results come from animal and laboratory research rather than large human clinical trials.

Researchers have mainly looked at BPC-157 for tendon and ligament healing, muscle injuries, wound healing, gastrointestinal protection, inflammation, and nerve/tissue repair.

Proposed mechanisms include effects on angiogenesis, fibroblast activity, nitric-oxide signalling and tissue remodeling. This is why it has become popular in bodybuilding and sports-recovery circles.
