BPC-157 (Body Protective Compound 157) is a synthetic pentadecapeptide composed of 15 amino acids, derived from a fragment of human gastric juice protein. It has become one of the most frequently searched research peptides worldwide, particularly within tissue repair and regenerative research programs.
What researchers study
In preclinical models, BPC-157 has been investigated for its potential role in angiogenesis, collagen deposition, and the healing of tendons, ligaments, muscle, and the gastrointestinal tract. Most published work consists of in vitro studies and animal models; high-quality human clinical trials remain limited.
Common specifications
- Typical vial sizes: 5 mg and 10 mg lyophilized powder
- Purity offered by reputable vendors: 98% or greater, verified by HPLC
- Reconstitution: bacteriostatic water or acetic acid buffer, depending on the protocol
- Storage: refrigerated, protected from light after reconstitution
How to evaluate a supplier
Request the certificate of analysis (CoA) for the specific lot, confirm independent third-party HPLC and mass-spectrometry testing, and verify that the vendor labels every product “for research use only.” Suppliers who provide lot-traceable documentation, clear purity figures, and stable cold-chain shipping are significantly lower risk than discounters who cannot.
Sourcing tips
Compare price per milligram across vendors, but never at the expense of documentation. BPC-157 is frequently blended with TB-500 and GHK-Cu; if you purchase a blend, confirm the exact milligram content of each active rather than a single total figure.
