BPC-157 (Body Protection Compound-157) is a synthetic 15-amino acid peptide derived from a gastric protective protein found in human gastric juice. It is one of the most extensively studied research peptides in preclinical literature, with hundreds of published animal model studies examining its roles in tissue repair, angiogenesis, and gastrointestinal function.
What researchers study
In controlled laboratory settings, BPC-157 is primarily investigated for angiogenic signaling — the formation of new blood vessels — as well as fibroblast activity, nitric oxide pathway modulation, and tissue repair mechanisms. Animal models have examined its effects on musculoskeletal, tendon, ligament, and gastrointestinal systems. It is the core active ingredient in both the GLOW blend (BPC-157 + TB-500 + GHK-Cu) and the KLOW blend (which also contains KPV).
COA verification checklist
Because BPC-157 is one of the most counterfeited peptides on the market, COA verification is critical. A legitimate COA must come from a named third-party lab (not in-house), include an HPLC chromatogram showing purity ≥99%, and include mass spectrometry confirming the molecular identity (MW 1419.54 g/mol). The lot number on the vial must match the COA document. Pre-dissolved liquid formats should be avoided — legitimate BPC-157 ships as lyophilized powder.
Price benchmarks (2026)
Budget vendors charge $26–35 per 5mg vial. Mid-tier vendors with strong COA documentation charge $36–50. Premium vendors with lot-specific public COAs charge $51–70. Prices below $25 per 5mg are a red flag — the cost of legitimate third-party testing alone exceeds this threshold.
