What is GHK-Cu?
GHK-Cu is a naturally occurring copper complex formed when glycyl-L-histidyl-L-lysine binds copper ions. Its interaction with copper and extracellular-matrix biology has made it interesting to researchers studying skin, fibroblasts, collagen and tissue remodelling.
What is GHK-Cu being studied for?
Laboratory research has examined GHK-Cu in relation to fibroblast biology, collagen production and turnover, glycosaminoglycans, metalloproteinases, extracellular-matrix remodelling and skin biology.
GHK vs GHK-Cu
GHK is the three-amino-acid peptide itself. GHK-Cu is the copper-bound complex. They are closely related but chemically distinct forms.
Evidence status
Mechanistic and cellular evidence is substantial. Human cosmetic evidence is less extensive than many online claims suggest.
