GHK-Cu is the copper-bound form of the tripeptide glycyl-L-histidyl-L-lysine — a naturally occurring copper-binding peptide. Supplied as a lyophilised powder in a sealed vial, labelled at 100 mg.
Copper peptides are light-sensitive, so keep the vial sealed, cool and away from direct light. GHK-Cu also forms part of our GLOW and KLOW blends.
