GHK-Cu
Also known as: Copper tripeptide-1, Glycyl-L-histidyl-L-lysine copper
GHK-Cu is a naturally occurring copper-binding tripeptide widely studied in skin, tissue-remodeling, and gene-expression research, and used as a cosmetic ingredient.
View GHK-Cu product →What is GHK-Cu?
GHK-Cu is the tripeptide glycyl-L-histidyl-L-lysine complexed with copper. It occurs naturally in human plasma, where its concentration declines with age, and it has a strong affinity for copper ions.
It is one of the best-characterized copper peptides in the research literature and is a common cosmetic ingredient.
How GHK-Cu is studied
Research has examined GHK-Cu for its role in copper transport and in modulating gene expression associated with tissue remodeling and the extracellular matrix. Studies have looked at effects on collagen and related structural proteins in laboratory models.
Research applications in the literature
Published work has investigated GHK-Cu in skin, wound-model, and hair-follicle research, as well as broader gene-expression profiling. Much of the interest centers on its copper-binding chemistry.
Handling, reconstitution & storage
GHK-Cu ships lyophilized (with its characteristic blue color from the copper complex) and is stored at -20°C, protected from light. Reconstituted with sterile or bacteriostatic water, it is held at 4°C short-term or aliquoted at -80°C. Each lot ships with an HPLC certificate of analysis.
Frequently asked questions
What is the copper in GHK-Cu for?
The peptide GHK binds a copper ion; the copper complex is central to the chemistry that researchers study, and it gives the lyophilized powder its blue tint.
How is GHK-Cu stored?
Lyophilized at -20°C protected from light; once reconstituted, at 4°C short-term or aliquoted at -80°C.
