Retabionix summary of this report (PDF)
Composition

GHK-Cu.

GHK-Cu is the tripeptide glycyl-L-histidyl-L-lysine coordinated to a copper(II) ion. The copper is part of the material, which is why the molecular formula carries it and why the powder is blue rather than white.

It is made by solid-phase synthesis and supplied as a lyophilized powder in a sealed vial. The certificate for each lot covers identity, purity and copper content.

We do not give guidance on preparing, using or applying any material. Whether a compound suits your research is for you or your institution to decide.
