This review article examined the literature and patent records regarding BPC 157, a 15-amino acid peptide, to assess its multifunctional properties and potential medical applications across various physiological systems including gastrointestinal, cardiovascular, neurological, and musculoskeletal tissues (review of human clinical, animal model, and in vitro studies). The review identified multiple proposed mechanisms of action and documented findings from preclinical and clinical investigations suggesting potential therapeutic effects in conditions such as gastrointestinal ulcers, wound healing, and neuroprotection, though the authors noted the need for further rigorous clinical validation. This is a review article synthesizing existing evidence from multiple study types rather than original research.
