BPC-157 is a 15-amino acid peptide derived from human gastric juice that promotes angiogenesis via dual VEGFR2-dependent (PI3K-Akt-eNOS) and VEGF-independent (Src-Caveolin-1-eNOS) nitric oxide pathways. It upregulates growth hormone receptor expression, modulates the FAK-paxillin pathway for cell migration, and counteracts damage to the nitric oxide system. Additionally, it enhances tendon fibroblast growth, promotes reticulin and collagen formation, and accelerates wound healing by mediating the NO system's protective functions.

Pentadeca Arginate is a synthetic 15-amino acid peptide utilizing an arginate salt formulation of the BPC-157 sequence, designed to enhance nitric oxide production and promote angiogenesis. It stimulates collagen synthesis, enhances tissue repair through increased tensile strength, reduces inflammation via modulation of inflammatory cytokines, and accelerates cellular proliferation in tendon fibroblasts. The arginate salt form provides superior stability and bioavailability compared to traditional acetate formulations.
