GHK-Cu (Copper Peptide) at a glance
GHK-Cu is the tripeptide glycyl-histidyl-lysine bound to copper. Studied for wound healing, skin regeneration, hair growth, and anti-inflammatory effects. Mechanism: Copper-binding tripeptide. Typical route: Subcutaneous or topical. FDA status: Not FDA-approved as a finished drug product. GHK-Cu in topical cosmetic preparations is regulated as a cosmetic ingredient (not a drug). Injectable forms are dispensed by compounding pharmacies.
Drug classCopper-binding tripeptide
Half-life~2 hours (parenteral)
RouteSubcutaneous or topical
Common dosing1-2 mg SC, 2-3x/week
FDA statusNot approved (drug)
Cosmetic statusPermitted ingredient
Mechanism of action
GHK-Cu binds to copper ions to form a complex that promotes collagen and elastin synthesis, activates antioxidant pathways, modulates gene expression toward a younger phenotype (per genomic studies), and supports angiogenesis in wound healing.
Dosing reference
Subcutaneous: 1-2 mg per injection, 1-3 times weekly. Topical formulations: 0.05% to 5% cream, applied once or twice daily. Cosmetic preparations are widely available; injectable forms require a prescription.
