Body Protection Compound-157 (BPC-157) is a synthetic peptide consisting of 15 amino acids, also referred to as a pentadecapeptide. It was originally identified in the 1970s during research involving human gastric fluid. BPC-157 is known for its molecular structure, which includes naturally occurring modifications such as N-terminal acetylation and C-terminal amidation on a significant portion of the peptide.
These structural features may contribute to its chemical stability. BPC-157 continues to be studied in laboratory settings for its physical and biochemical characteristics.
