GHK-Cu Copper Peptide | 60mg | 3ml
GHK‑Cu is an endogenous copper–peptide complex that acts as a natural signalling molecule involved in metal transport and cellular regulation. It is composed of the tripeptide glycyl‑L‑histidyl‑L‑lysine bound to a divalent copper ion, forming a high‑affinity chelated structure that enables controlled copper handling within biological environments. In biochemical and cellular research, GHK‑Cu influences signalling activity through both its peptide component and the biochemical functions of copper itself. Copper is an essential trace mineral required for a wide range of enzymes and structural proteins that support redox balance, extracellular matrix formation, and metabolic processes. By serving as a carrier and regulator of bioavailable copper, GHK‑Cu contributes to maintaining metal homeostasis and modulating downstream pathways associated with cellular proliferation, differentiation, and tissue remodelling. Across preclinical research systems, GHK‑Cu exposure has been linked to shifts in gene expression and modulation of pathways governing extracellular matrix turnover, oxidative stress responses, and cellular renewal. These outcomes vary according to concentration, exposure duration, and experimental model, making GHK‑Cu a versatile tool for studying copper‑dependent signalling and peptide–metal interactions in both in vitro and in vivo contexts.

How we ship it
Every pre-mixed vial leaves the UK cold and arrives in a plain box. Refrigerate on arrival at 2–8 °C.
Chilled
Vials travel with frozen gel packs inside a sealed foil pouch, which holds temperature for roughly seven days in transit.
Insulated
The pouch sits inside a wool-lined envelope, so the cold chain survives a normal courier journey.
Discreet
Plain outer box with no branding and nothing on the label that names the contents.
Same-day dispatch
Order before 3pm GMT, Monday to Friday.
Free over £100
Tracked UK delivery, next working day.
2–8 °C on arrival
Refrigerate as soon as the parcel lands.

GHK-Cu: research FAQs
- What is GHK-Cu?
- GHK-Cu is a copper-peptide complex formed from the tripeptide glycyl-L-histidyl-L-lysine bound to a divalent copper ion. This high-affinity chelated structure belongs to the family of endogenous metal-binding peptides. It is supplied strictly as a reference compound for in-vitro laboratory research use only.
- What is GHK-Cu studied for in research?
- In cell-based and biochemical laboratory research, GHK-Cu has been investigated for its copper-binding behaviour and, in preclinical models, for associations with pathways relating to gene expression, extracellular matrix turnover and oxidative-stress responses. These are in-vitro and preclinical laboratory observations only. They vary with concentration, exposure duration and experimental model, and are not established effects in humans or animals.
- Is GHK-Cu legal to buy in the UK?
- GHK-Cu is legal to buy and possess in the UK for laboratory research purposes. It is not a licensed medicine and cannot be sold for human or veterinary consumption. Every vial is labelled and supplied for in-vitro research use only.
- What purity is your GHK-Cu, and is it lab-tested?
- Our GHK-Cu is verified at 99%+ purity by high-performance liquid chromatography (HPLC). The purity figure printed on each batch's Certificate of Analysis is the actual value recorded in the laboratory for that batch, not a generic marketing claim. It is synthesised and dispatched from our own UK facility.
- Does GHK-Cu come with a Certificate of Analysis?
- Yes. A batch-specific Certificate of Analysis (COA) ships with every order, documenting the identity and purity of the material you receive. Sample COAs can also be viewed in our COA library before you buy, so you can review our testing standards in advance.
- How is GHK-Cu supplied, stored and handled for research?
- GHK-Cu is supplied as a pre-mixed solution in a sealed vial — no reconstitution step is required. Its batch Certificate of Analysis records the appearance as a blue liquid, which is characteristic of the copper-peptide complex. Refrigerate at 2°C–8°C, keep the vial sealed and away from light, and do not freeze it. Handling should follow standard aseptic laboratory practice for research reagents.
