GHK-Cu is a copper peptide made from the tripeptide GHK bound to copper. Copper is involved in skin and connective-tissue biology, and GHK-Cu is best known because it connects copper signalling with collagen, elastin, glycosaminoglycans, wound-response models, and tissue remodelling.

People look at GHK-Cu because it sits at the centre of the skin-quality and tissue-remodelling peptide category. The main interest is around skin texture, collagen and elastin activity, connective tissue, hair and follicle research, and visible ageing biology.

GHK-Cu carries copper into signalling environments where copper-dependent enzymes are involved in tissue repair, antioxidant activity, collagen formation, and extracellular-matrix remodelling. In plain terms, it is interesting because copper is part of the machinery skin and connective tissue use to maintain structure.

GHK-Cu is often compared with BPC-157, TB-500, and KPV. GHK-Cu is the copper-peptide skin and tissue-remodelling compound, BPC-157 and TB-500 sit closer to repair signalling and cell movement, and KPV adds the inflammation and barrier-tissue angle.
