Naturally occurring copper tripeptide. Almost all clinical evidence is topical; subcutaneous dosing is not established in human trials and the SC range below is extrapolated from anecdotal protocols. In cultured fibroblasts, GHK-Cu raised collagen type 1 expression (Maquart/Pickart, FEBS Lett 1988, PMID 3169264). Studied for skin remodeling, wound healing, and hair growth.
