Copper Delivery & Gene Expression Modulation
GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper complex, CAS: 49557-75-7) is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine — concentrations decline significantly with age (~200ng/mL at age 20 to ~80ng/mL by age 60). GHK-Cu modulates the expression of over 4,000 human genes, promoting wound healing and remodeling genes while downregulating inflammatory and oncogenic pathways. As a copper chaperone, it delivers Cu²⁺ to cuproenzymes including lysyl oxidase (collagen/elastin crosslinking) and superoxide dismutase (SOD1/SOD3). Fibroblast studies show increased synthesis of collagen types I, III, and IV, metalloproteinase activation for old collagen breakdown, and TIMP-1/2 upregulation to prevent excessive matrix degradation. Molecular weight: 340.38 Da (free tripeptide).
