The free-base tripeptide glycyl-L-histidyl-L-lysine (CAS 49557-75-7), present naturally in human plasma at ~200 ng/mL in adulthood and declining with age. Modulates wound-healing gene expression, upregulates collagen and glycosaminoglycan synthesis, and increases expression of antioxidant defense genes; binds copper(II) with high affinity to form the GHK-Cu complex used in cosmetic applications. Distinct from the copper-complexed ghk-cu row (CAS 89030-95-5) — the two have different pharmacology and commercial-intent profiles. Not FDA-approved.
