About GHK-Cu
About GHK-Cu
Origin Peptides GHK-Cu Vial is a 50 mg or 100 mg lyophilised (freeze-dried) single compound research vial from Origin Peptides, sealed under nitrogen, batch numbered and cold stored. Supplied strictly for laboratory research; not for human or veterinary use.
Handling and storage
GHK-Cu is supplied as lyophilised powder in 50 mg or 100 mg vials, larger quantities than most of the range. Keep the vials sealed, dry, at -20C and away from light, and log the batch number with each one. Bacteriostatic water and other lab supplies are sold separately. No reconstitution or usage guidance is given on this site.

What the published research says
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine. GHK was first described in human serum by Pickart and Thaler (Nature New Biology, 1973), and its strong affinity for copper ions shaped most of the research that followed.
Maquart and colleagues (FEBS Letters, 1988) reported increased collagen synthesis in fibroblast cultures exposed to the copper complex, and Siméon and colleagues (Journal of Investigative Dermatology, 2000) studied glycosaminoglycans and small proteoglycans in rat wound models. Pickart and Margolina (International Journal of Molecular Sciences, 2018) reviewed gene expression datasets in which GHK was linked to changes across a large number of human genes.
Human data are limited to cosmetic studies of topical products. No published human trial has studied GHK-Cu outside topical products, and findings for the copper complex should not be read across to GHK alone.
Research profile
GHK-Cu scores equally for tissue repair and for cognition and longevity, because its papers concentrate on wound and extracellular matrix biology on one side and skin ageing and gene expression data on the other. The weighting summarises the literature and makes no claim of effect. GHK-Cu sits in the Tissue & Recovery group of the Origin Peptides research peptides range. New to the category?

Lab testing
Every batch of GHK-Cu is tested by an independent laboratory before it is released, with identity confirmed by HPLC or LC-MS and the purity stated on the certificate.
Each vial carries a batch number. The certificate of analysis is published on the Lab Testing page, so you can match the report to the number on your vial.

Questions
Is GHK-Cu legal to buy in the UK? Yes. GHK-Cu is not a controlled substance, and copper tripeptide-1 is a listed cosmetic ingredient (INCI). This vial is laboratory research material, not a cosmetic or a medicine, so no usage guidance is given.
What is the difference between GHK and GHK-Cu? GHK is the tripeptide on its own (340.4 g/mol). GHK-Cu is the same tripeptide holding a copper(II) ion (about 401.9 g/mol), which is the form most of the published work studied.
Is GHK-Cu in any Origin Peptides blend? Yes. The GLOW blend combines GHK-Cu with BPC-157 and TB-500; the GLOW blend guide sets out what has been studied for each part.
Research use only. This product is supplied strictly for laboratory and research purposes and is not for human or veterinary use. It is not a medicine, not a food supplement and not intended to diagnose, treat, cure or prevent any disease. Sold to persons aged 18 or over only.
