About GHK-Cu
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine. GHK was first isolated from human plasma in the early 1970s by Loren Pickart, and its strong affinity for copper ions made the copper complex the most widely studied form.
Canada Research Labs supplies GHK-Cu as 50mg of lyophilized powder in a 3 mL glass vial, packed and shipped from Ontario. The powder has the characteristic blue colour of copper(II) complexes.
See our GHK-Cu research overview.
Research background
GHK-Cu has one of the longest research histories of any small peptide, spanning five decades. Early cell-culture work examined its effect on collagen synthesis by fibroblasts, and later studies extended to gene expression. A 2018 review by Pickart and Margolina (International Journal of Molecular Sciences) summarizes gene-expression analyses in which GHK was associated with changes across a large number of human genes.
Much of the literature is preclinical or in vitro. Because GHK binds copper tightly, studies typically specify whether the free peptide or the copper complex was used, and researchers should note which form they are working with.
