GHK-Cu stimulates angiogenesis primarily through upregulation of key growth factors including vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF/FGF-2), with research demonstrating that GHK-Cu at nanomolar concentrations increases VEGF expression in dermal fibroblasts and stimulates human umbilical vein endothelial cell (HUVEC) proliferation through enhanced VEGF and FGF-2 expression
