GHK-Cu

A naturally occurring copper-binding tripeptide, Gly-His-Lys complexed with copper, studied for skin elasticity, wound healing, hair follicles and antioxidant pathways.

What it is

GHK-Cu is a copper-binding tripeptide: the sequence glycine-histidine-lysine (Gly-His-Lys) complexed with a copper ion. It occurs naturally in the body, where its plasma levels are known to decline with age, a fact that makes it a frequent subject in regeneration and skin-biology research.

What the research looks at

Research on GHK-Cu spans several pathways: skin elasticity, wound healing, hair-follicle activity and antioxidant signalling. Because copper is central to the molecule, studies often examine how the bound ion participates in remodelling and repair. Investigators also look at how supplementing the tripeptide affects models in which its natural, age-declining levels are low. Supplied strictly for laboratory research use only, not for human or veterinary use.

Preparing it

The vial ships as a lyophilized powder and is reconstituted with bacteriostatic water (or sterile water for single-session work) before use. Pick a diluent volume that gives a concentration you can read cleanly on a U-100 syringe. See reconstitution for the method and the concentration formula for the maths.
