Loren Pickart human plasma Cu Copper Complex Blue-green solution is normal Mechanism of Action How GHK-Cu Works Copper delivery, collagen synthesis activation, and 4,000+ gene modulation COPPER Primary Copper Ion Delivery Cu Complexation & Delivery Delivers bioavailable Cu to tissue Activates copper-dependent enzymes Supports lysyl oxidase for collagen crosslinking COLLAGEN Key Collagen & ECM Synthesis TGF- / Fibroblast Activation Upregulates collagen I and III synthesis Increases fibronectin and laminin production Activates dermal fibroblast proliferation GENOMIC 4,000+ Gene Expression Modulation Broad Transcriptomic Effects Activates tissue repair gene networks Downregulates inflammation pathway genes Modulates Wnt and TGF- signaling Key finding: GHK-Cu plasma levels decline from ~200 ng/mL in young adults to ~80 ng/mL by age 60 a 60% reduction
