GHK-Cu (Copper Tripeptide-1) — Research Grade
GHK-Cu is a naturally occurring copper-binding tripeptide — glycyl-L-histidyl-L-lysine complexed with a copper(II) ion. Ascend Research supplies it as a lyophilised powder with the characteristic blue colouration of the copper-bound complex, in 50mg and 100mg vials at ≥99% purity, dispatched from within Australia for laboratory research use only.

Research Context
GHK-Cu is one of the most extensively characterised copper-binding peptides in the biochemical literature. It was first isolated from human plasma in 1973 and has since been studied in matrix biology, copper transport, and in vitro fibroblast research. Ascend Research supplies GHK-Cu strictly as a laboratory reference material; no representation is made regarding any physiological outcome, and it is not supplied for use in humans or animals.
Handling and Reconstitution
Allow the vial to reach room temperature before opening. Reconstitute with sterile water; the copper complex produces a blue solution. Store the lyophilised powder dry at 2–8°C away from light, and refrigerate reconstituted material, using it within 30 days. Avoid repeated freeze–thaw cycles.
What's Included
- One lyophilised vial (50mg or 100mg, as selected)
- Protective packaging
Frequently Asked Questions
What is the CAS number for GHK-Cu?
89030-95-5.
What is the difference between GHK and GHK-Cu?
GHK is the free tripeptide (C₁₄H₂₄N₆O₄, ~340.4 g/mol). GHK-Cu is the same tripeptide complexed with copper(II), giving a higher molecular weight (~403.9 g/mol) and the characteristic blue colour.
Why is the powder blue rather than white?
The blue colouration comes from the bound copper(II) ion and is expected for correctly complexed material.
Should I choose the 50mg or 100mg vial?
Vial size is a matter of research scale and storage preference. Both are the same material at the same ≥99% purity.
How should GHK-Cu be stored?
Dry at 2–8°C, protected from light. Refrigerate after reconstitution and use within 30 days.
Where does Ascend Research ship from?
Orders are dispatched from within Australia.
