Overview
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys), a naturally occurring copper-binding peptide. This is our larger 100mg lyophilised vial, supplied as a powder for laboratory use.
As a research compound it is studied in vitro for its copper-binding chemistry and its role in collagen- and extracellular-matrix research. It is supplied strictly as a research reference material; it is not a cosmetic and is not for human or animal consumption.
Research areas
- Copper(II) coordination chemistry of the GHK tripeptide, studied in vitro
- Collagen-synthesis and extracellular-matrix research models
- Fibroblast and skin-cell research models
- Comparative studies of copper-peptide complexes
At a glance
- Same GHK-Cu compound — 99% HPLC-verified (report run on the 50mg vial)
- 100mg lyophilised vial — double the 50mg fill
- UK stocked, 24–48h dispatch after payment
- Stored frozen until dispatch
Storage and handling
Supplied as a lyophilised powder in a sealed vial and kept frozen until dispatch. Unopened vials are typically stored at -20°C for the long term and 2-8°C for short periods. After reconstitution, vials are generally refrigerated at 2-8°C, protected from light, and not subjected to repeated freeze-thaw cycles.

Questions
What is GHK-Cu 100mg?
The copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys), supplied as a 100mg lyophilised vial for research — the same compound as our 50mg GHK-Cu, at double the fill.
Has this GHK-Cu been independently tested?
The GHK-Cu compound was sent to Analiza Białek sp. z o.o., an independent laboratory in Wrocław, Poland, and returned 99% purity by HPLC. That report was run on our 50mg vial; this 100mg vial is the same compound at a larger fill. The full certificate is published on the site.
What is GHK-Cu 100mg supplied as?
A 100mg lyophilised vial, stored frozen until dispatch. Supplier documentation is available on request where held.
Do you stock GHK-Cu 100mg in the UK?
Yes. It is UK stocked with dispatch within 24–48 hours of confirmed payment on business days via tracked delivery.
Is GHK-Cu for research use only?
Yes. It is supplied strictly for laboratory research, is not a cosmetic, and is not for human or animal consumption.
