About GHK-Cu

GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine) originally isolated from human plasma. Since its identification in 1973 it has been the subject of extensive preclinical literature, with published studies investigating collagen synthesis assays in fibroblast cultures, gene-expression profiling, and antioxidant chemistry across the peptide and dermatology-research fields.

All GHK-Cu sold by BioInfinity is manufactured by solid-phase peptide synthesis (SPPS), chelated with a stoichiometric equivalent of copper(II), purified by reverse-phase HPLC, and confirmed by mass spectrometry and UV-vis spectrophotometry to >99% purity. It ships as a lyophilized (freeze-dried) blue-tinted powder in a septum-sealed vial, ready for reconstitution with bacteriostatic water for laboratory use.
