GHK-Cu is the copper complex of the tripeptide glycyl-L-histidyl-L-lysine. It is small, it binds copper, and it shows up in dermatological and cell-culture research rather than in incretin or growth-hormone papers.
What the studies look at
In vitro papers report effects on collagen synthesis, metalloproteinases, and antioxidant gene expression in fibroblast models. Animal and explant work has looked at wound-closure models. Those designs do not transfer into a home protocol, and this product is not sold for that.
Handling notes for the lab
Copper peptides are sensitive to pH and to chelators. A research COA should show peptide identity and purity. It will not tell you a cosmetic concentration. Match the lot number on the vial to the certificate before you log the material into an experiment.
