BPC-157
A synthetic 15-amino-acid peptide studied extensively in preclinical tissue-repair, gastrointestinal, and vascular research.
BPC-157 (Body Protection Compound-157) is a synthetic peptide composed of 15 amino acids, derived from a partial sequence of a protective protein found in human gastric juice. It is one of the most widely studied research peptides in the preclinical literature, with rodent-model evidence spanning tissue repair, gastrointestinal protection, and vascular research.
Researchers are drawn to BPC-157 in part because of its reported stability in gastric acid — unusual among peptides — and its apparent activity across multiple tissue types in laboratory models. It is frequently studied alongside TB-500 in tissue-repair research. The evidence base is overwhelmingly preclinical: there are no published human clinical trials establishing efficacy or safety in humans.
Research areas
Tendon & Ligament Repair
Among the most-studied areas. Rodent models have examined effects on tendon-to-bone healing, fibroblast migration, and tissue repair in controlled experiments.
Gut & GI Tract Research
Derived from a protein in gastric juice; investigated for intestinal anastomosis healing, gut-barrier integrity, and inflammatory bowel models.
Angiogenesis & Vascular
Studied for a role in promoting blood-vessel formation (angiogenesis) via the VEGFR2 pathway, relevant to wound-healing research.
Neuroprotection (Emerging)
Newer preclinical work examines gut-brain axis interactions and neuroprotective signaling — a fast-growing area of investigation.
Recent research findings
- 2024Preclinical work continued exploring interaction with the nitric oxide (NO) system and growth-factor signaling in tendon fibroblasts.
- 2023Reviews catalogued the breadth of rodent-model cytoprotection evidence across gut, muscle, and tendon tissue, noting the absence of human trials.
- 2022Investigations into gut-brain axis signaling expanded the proposed mechanism beyond peripheral tissue repair.
