What is GHK-Cu?
GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a tripeptide that forms a complex with copper ions (Cu²⁺). This article classifies it, according to the literature, in relation to ECM markers, collagen and cellular signalling in laboratory models.
ECM and redox markers
In laboratory models, GHK-Cu is discussed in relation to type I/III collagen markers, elastin, glycosaminoglycans, MMPs and SOD-related redox signalling.
Literature classification
The related category covers ECM, fibroblast models, gene expression and cellular response. No cosmetic outcomes, practical instructions or product recommendation are presented.
