About this compound
GHK-Cu is a copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, first isolated from human plasma. The copper is coordinated by the histidine imidazole and the peptide backbone, giving the material its distinctive deep blue colour in both powder and solution.
Studied in
- Dermal matrix signalling
- Fibroblast behaviour
- Follicular research

GHK-Cu, and the tripeptide that turned up in human serum
A three-residue peptide isolated from human plasma in 1973 binds copper avidly, and almost everything studied since has been the copper complex. Here is what the cell and animal work actually measured.
