Overview
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys), a naturally occurring copper-binding peptide. It is supplied as a lyophilised powder for laboratory use.
As a research compound it is studied in vitro for its copper-binding chemistry and its role in collagen- and extracellular-matrix research. It is supplied strictly as a research reference material; it is not a cosmetic and is not for human or animal consumption.

Storage and handling
Supplied as a lyophilised powder in a sealed vial and kept frozen until dispatch. Unopened vials are typically stored at -20°C for the long term and 2-8°C for short periods. After reconstitution, vials are generally refrigerated at 2-8°C, protected from light, and not subjected to repeated freeze-thaw cycles.
