BPC-157 (also known by older designations including PL-14736 and bepecin) has the amino acid sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val, a molecular weight of roughly 1,419.5 g/mol, and CAS number 137525-51-0 (PubChem CID 9941957)
Together, they address both vascular supply and cellular repair simultaneously, potentially accelerating overall tissue regeneration timelines beyond what either peptide achieves alone in preclinical models
AHK-Cu was designed for hair follicle cells, not dermal fibroblasts
Important: BPC-157 is not approved for human or veterinary use in Canada
However, a 2025 HSS Journal systematic review (544 articles screened, 36 included 35 preclinical, 1 clinical) concluded that high-quality clinical evidence remains limited and use should be approached with caution
