BPC-157

BPC-157 is a synthetic peptide of 15 amino acids derived from a partial sequence of a protein found in human gastric juice. It is most commonly discussed in the context of musculoskeletal recovery, tendon and ligament healing, and gastrointestinal repair. Within research and fitness communities it is frequently grouped with TB-500 as a "recovery" peptide. The great majority of published BPC-157 research is preclinical, conducted in rodents and in vitro. These studies report effects on wound healing, angiogenesis, and gut protection. Human evidence remains scarce: only a handful of small, mostly unblinded pilot studies exist, with no large randomized placebo-controlled trials establishing efficacy or long-term safety as of 2026. BPC-157 is not an approved drug in the United States, the EU, or most jurisdictions. The FDA has flagged it as a substance not eligible for compounding, and it is prohibited in sport by WADA. Material sold online is typically labeled "for research use only," and the claims around it should be read with that regulatory and evidentiary context in mind.
