GHK-Cu is a copper-binding tripeptide (glycyl-L-histidyl-L-lysine complexed with copper). It is among the most-studied peptides in regenerative and skin-research literature. This guide reviews the reported mechanism for in-vitro research context.
Mechanism
In preclinical models, GHK-Cu has been studied for roles in collagen synthesis, extracellular-matrix remodeling, and antioxidant signaling, with the copper ion central to its activity. Wound-healing and skin-repair endpoints are the most commonly reported in the literature.
GHK-Cu is supplied as a research material and is studied in vitro. Its handling follows the general storage guidance for copper-complexed peptides — kept cold, dry, and protected from light.
