behind the compound.
Overview
GHK-Cu is a naturally occurring tripeptide-copper complex — glycyl-L-histidyl-L-lysine chelated to a copper(II) ion — first isolated from human plasma in 1973. Its endogenous levels are documented to decline with age, and the bound copper gives the complex its characteristic blue-purple color.
It is a signature reference in the radiance category, studied for its role in models of tissue-remodeling and skin-matrix signaling.

Storage & handling
Store the lyophilized powder at −20°C, protected from moisture. It is characterized as stable across a mildly acidic-to-neutral pH range and dissociates outside it; hold reconstituted solution cold.
