GHK-Cu (glycyl-L-histidyl-L-lysine:copper(II)) is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. Plasma levels decline from ~200 ng/ml at age 20 to ~80 ng/ml by age 60. GHK-Cu activates collagen I, III, and IV synthesis, promotes elastin production and glycosaminoglycan accumulation, modulates metalloproteinases (MMPs) for controlled ECM remodeling, and stimulates decorin expression for organized collagen fiber formation. It influences over 4,000 genes related to tissue repair, inflammation control, and antioxidant defense. Clinical studies have shown 70% of subjects experienced increased collagen production with topical GHK-Cu — outperforming both vitamin C and retinoic acid.
