Research Use Only
GHK-Cu 50mg is the copper complex of GHK (glycyl-L-histidyl-L-lysine), a naturally occurring tripeptide, supplied in one pre-filled research pen. GHK was first isolated from human plasma and binds copper(II) ions with high affinity. Every GHK-Cu pen is prepared to order in the UK and shipped cold chain by tracked delivery.
GHK-Cu is studied mainly in fibroblast cultures, skin models and gene-expression data. Read our GHK-Cu research overview for its classification and history, or see how it is combined with other peptides in GLOW and KLOW.
How GHK-Cu is studied
Much GHK-Cu research centres on copper delivery to cells and on fibroblast activity. In early fibroblast-culture work, the copper complex increased collagen synthesis. Later analyses of public gene-expression data linked GHK to changes in the activity of many human genes, including genes involved in extracellular-matrix remodelling and antioxidant responses.
5 key research areas
- Collagen and extracellular matrix. Fibroblast-culture studies examined GHK-Cu for its effect on collagen and glycosaminoglycan synthesis.
- Copper binding and transport. GHK forms a stable complex with copper(II), and researchers study it as a carrier of copper to cells.
- Gene expression. Analyses of the Broad Institute’s Connectivity Map linked GHK to changes in the expression of a large number of human genes.
- Oxidative stress models. Reviews describe GHK-Cu in laboratory models of oxidative stress and antioxidant gene activity.
- Skin models. GHK-Cu appears widely in in-vitro and animal skin and wound models.

What is GHK-Cu?
GHK-Cu is the copper complex of GHK (glycyl-L-histidyl-L-lysine), a tripeptide first isolated from human plasma. It has been studied in fibroblast cultures, skin models and gene-expression research. Apexion supplies it for laboratory research only.
What is the difference between GHK and GHK-Cu?
GHK is the tripeptide on its own. GHK-Cu is the same tripeptide bound to a copper(II) ion, which is the form used in most published research and the form supplied here.
How much GHK-Cu is in each pen?
Each pen contains 50 mg of GHK-Cu in one pre-filled research pen. GHK-Cu is also the largest component of our GLOW and KLOW blends, at 50 mg in each.
Is GHK-Cu independently tested?
Every GHK-Cu pen is made fresh after your order is placed, so each one is prepared and quality checked to order rather than taken from old stock. Independent third-party testing of GHK-Cu is under way, and the batch Certificate of Analysis will be published as soon as the results are verified. Each pen carries a batch number, so its documentation can be traced.
Can GHK-Cu be used in humans or animals?
No. GHK-Cu is not a medicine and is not licensed by the MHRA. It is supplied strictly for in-vitro laboratory research, and is not for human or veterinary use, diagnosis or treatment.
How should GHK-Cu be stored?
GHK-Cu is shipped cold chain. On arrival, keep the pen sealed and store it at −20 °C for long-term storage, away from heat and direct light. Handle it as little as possible and follow any batch-specific guidance supplied with your order.
