How This Works
BPC-157 is a synthetic peptide corresponding to a partial sequence of human gastric juice protein[2]. Preclinical studies suggest it modulates nitric oxide pathways and growth-factor expression to promote angiogenesis and collagen deposition in damaged tissues[1][3]. Animal models report accelerated healing of gut, tendon, ligament, and muscle injuries[6]. A Phase I oral safety trial has been completed[9], and a small human case series reported improvements following intra-articular preparation[5]; however, large-scale controlled human efficacy data are not yet available.
