GHK-CU research vial by Regent Peptides

Research compound

GHK-Cu

£20.00/ 50mg vial

Dosage

Copper tripeptide complex (glycyl-L-histidyl-L-lysine : Cu²⁺)

GHK-Cu is the copper(II) complex of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine, first isolated from human plasma in the 1970s. The peptide binds copper with high affinity through the histidine imidazole and the terminal amine, and the resulting complex has a characteristic blue colour in both powder and solution.

Regent Peptides supplies GHK-Cu as a blue lyophilised powder in 50 mg and 100 mg vials. Batches are manufactured in the UK and independently tested for purity and identity; copper content is confirmed as part of the specification.

GHK-Cu is among the most-published cosmetic and dermatological research peptides, appearing in literature on collagen and glycosaminoglycan synthesis in fibroblast culture, wound-model studies, and gene-expression profiling. It is also widely used as a reference compound in topical formulation research. Supplied for laboratory research use only.

Research Handling Guidance

Before reconstitution, allow both the lyophilised peptide and your chosen diluent to settle at normal laboratory room temperature. Equalising temperatures in this way supports the structural stability of the compound while it goes into solution.

Diluents and reconstitution solutions are purchased separately.

GHK-Cu questions

Why is GHK-Cu blue?
The colour comes from the copper(II) ion coordinated by the tripeptide. A strong blue in both powder and reconstituted solution is expected; a colourless powder would indicate the free peptide without copper.
How is GHK-Cu tested?
Each production batch is sent for independent HPLC purity analysis and mass spectrometry identity confirmation by Janoshik Analytical. The batch reference printed on the vial links to its Certificate of Analysis, which can be viewed on the lab's own verification site.
How is GHK-Cu supplied?
As a sterile lyophilised (freeze-dried) powder in a sealed glass vial, available in 50 mg and 100 mg vials. Vials are labelled with compound name, strength and batch reference and are dispatched in plain, tracked packaging from the UK.
How should the lyophilised vial be stored?
Unopened lyophilised vials should be kept refrigerated at 2–8 °C, or at −20 °C for long-term storage, protected from light. Once reconstituted, solutions should be refrigerated and used within the period appropriate to the laboratory's own stability data.
Is this for human use?
No. All Regent Peptides products are supplied strictly for in-vitro laboratory research. They are not medicines and are not for human or veterinary use, diagnosis or treatment.
