What is BPC-157 and how does it work?

BPC-157 (Body Protection Compound-157) is a synthetic peptide derived from a protein found in human gastric juice. Research shows it promotes tissue healing and regeneration through multiple mechanisms: stimulating angiogenesis (new blood vessel formation), enhancing collagen synthesis, modulating inflammatory responses, and promoting cellular survival pathways. Studies in animals demonstrate accelerated healing of tendons, ligaments, muscles, and even nervous tissue. BPC-157 appears to work through interactions with the nitric oxide system and growth factor signaling. Typical research protocols use 200-500 mcg daily via subcutaneous injection near injury sites or systematically. It's being investigated for conditions including tendon injuries, muscle tears, inflammatory bowel disease, and wound healing. However, human clinical trials are limited, and BPC-157 is not FDA-approved. Quality and sourcing vary significantly since it's primarily available through research chemical suppliers and compounding pharmacies rather than pharmaceutical manufacturers.
