That said, some users still report success with oral BPC-157 for general joint and tendon health, especially when paired with other foundational supplements like glutamine and collagen
BPC-157 Research Applications BPC-157 is investigated in in-vitro and animal models of angiogenesis and endothelial tube formation, tendon and ligament repair, gastrointestinal mucosal integrity and experimental colitis, nitric oxide pathway modulation, and cytoprotection across musculoskeletal, neural and digestive tissue
