What Is BPC-157?
The Peptide Discovered in Gastric Juice and Studied for Tissue Repair
Disclaimer: Information provided is for research and educational purposes only. BPC-157 is not approved by the FDA or any regulatory agency for human use.
Introduction
BPC-157 (Body Protection Compound 157) is a synthetic peptide of 15 amino acids, derived from a protein fragment found in human gastric juice. Discovered in 1993, it has shown broad tissue-repair effects in preclinical models, including muscle, tendon, nerve, and gastrointestinal healing.1 2
Laboratory data indicate BPC-157 promotes healing in muscles, tendons, nerves, and the gastrointestinal tract, acting via angiogenesis, modulation of the nitric-oxide system, and anti-inflammatory pathways.2 3
BPC-157 Fast Facts
Type: Synthetic pentadecapeptide
Sequence: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val
Discovered: 1993, Zagreb, Croatia (Dr. Sikiric)
Key Features: Oral stability, multi-system healing
Primary Research: Rodent models of GI, musculoskeletal, neuroprotection
Chemical Structure & Origin
Named for its Body Protection Compound origin and its position as fragment number 157, BPC-157’s 15-amino-acid sequence confers unusual stability—even in the acidic stomach environment4.
Discovery of BPC-157 and Research Milestones
In 1993, Dr. Predrag Sikiric and colleagues at the University of Zagreb first described BPC-157 in Journal of Physiology-Paris, detailing its stomach-stress organoprotection hypothesis and beneficial effects in rodent gastric-injury models4. Their isolation of BPC-157 from human gastric juice protein laid the foundation for decades of follow-up work on tissue regeneration and organ protection.
