- All peptides discussed in this article are supplied strictly for in vitro and in vivo laboratory research use only (RUO). None are approved for human therapeutic use, and none of the data presented constitute medical advice or clinical guidance. This comparison provides a direct mechanistic head-to-head between two of the most extensively researched repair peptides in the preclinical literature: BPC-157 (GEPPPGKPADDAGLV), whose wound healing mechanisms centre on VEGFR2-driven angiogenesis, EGF receptor transactivation, NO synthase modulation, and FAK/paxillin cytoskeletal assembly; and GHK-Cu (glycine-histidine-lysine copper complex), whose mechanisms centre on collagen I/III and elastin synthesis promotion, MMP-1 upregulation for matrix remodelling, Nrf2 antioxidant activation, and anti-inflammatory cytokine suppression. Together these represent the two dominant cellular mechanisms of tissue repair — neovascularisation and matrix reconstruction — operating in complementary and synergi
