About GHK-Cu
GHK-Cu is a naturally occurring tripeptide — glycyl-L-histidyl-L-lysine — complexed with copper(II). The copper affinity of the GHK sequence makes it one of the most widely studied metal-binding peptides in matrix-biology and gene-expression literature.
Purvexis supplies GHK-Cu as a lyophilised blue-tinted powder in vials and as a measured spray. Colour intensity varies with the copper complex and is normal; purity is confirmed at ≥99% by HPLC for every lot.
Studied in the literature for
- Copper-chelation chemistry and complex-stability measurement
- Fibroblast and keratinocyte cell-culture gene-expression studies
- Extracellular-matrix and collagen-synthesis in-vitro models
- Peptide-copper formulation and stability research
Handling and storage
- The powder and solution are blue — this is the copper complex, not contamination
- Store sealed at 2–8 °C protected from light; avoid contact with reducing agents
- Reconstitute with sterile or bacteriostatic water; avoid chelating buffers such as EDTA
GHK-Cu — Frequently Asked Questions
What is GHK-Cu?
GHK-Cu is the tripeptide glycyl-L-histidyl-L-lysine bound to a copper(II) ion. It is studied in matrix-biology, gene-expression and metal-binding research. Purvexis supplies it as a research chemical only.
Why is GHK-Cu blue?
The blue colour comes from the copper(II) ion coordinated by the GHK tripeptide. A blue powder or solution is the expected appearance for authentic GHK-Cu and is not a sign of degradation.
What purity is your GHK-Cu?
Every GHK-Cu batch is tested by HPLC and mass spectrometry to ≥99% purity. A third-party certificate of analysis (COA) is available on request for the exact lot you receive.
Is GHK-Cu sold for human use?
No. GHK-Cu is supplied strictly as a research chemical for in-vitro and laboratory research use only. It is not a drug, food or dietary supplement, and it is not for human or veterinary use, diagnosis or treatment.
How should GHK-Cu be stored?
Lyophilised GHK-Cu is shipped at ambient temperature and is stable in transit. Store the sealed vial refrigerated at 2–8 °C, protected from light, for long-term storage; once reconstituted with bacteriostatic water, keep refrigerated and use within the window your protocol specifies.
How fast does GHK-Cu ship?
Every order ships free via USPS Priority Mail, typically arriving in 2–3 business days. Orders placed before the daily cut-off are packed the same business day, and tracking is emailed as soon as the label is generated.
≥99% purity, third-party COA verified, manufactured in the USA. For research use only — not for human or veterinary use.
