GHK (Gly-His-Lys) is a naturally occurring tripeptide found in human plasma, saliva, and urine that declines with age. It is a copper-binding peptide known for its regenerative and protective properties in skin and tissue repair. GHK has been extensively studied for its role in wound healing, collagen synthesis, and anti-aging applications.
Research protocols typically involve topical application at concentrations of 0.05-2% in cosmetic formulations, or subcutaneous injection at doses of 1-3 mg per session, 2-3 times weekly. When used systemically, cycles of 4-8 weeks are common with periodic breaks. Topical application is generally performed once or twice daily.
GHK functions by binding copper ions and modulating gene expression related to tissue remodeling and repair. It stimulates collagen and glycosaminoglycan synthesis while promoting angiogenesis and nerve outgrowth. The peptide also demonstrates anti-inflammatory effects by modulating metalloproteinase activity and enhancing antioxidant enzymes, while resetting genes to a more youthful state.
