GHK-Cu

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, dispatched from within Australia for laboratory research use only.

Specifications

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.

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 listed appearance is blue lyophilised powder. Appearance alone does not establish chemical identity or purity; refer to the documentation applicable to the supplied 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.

How should GHK-Cu be stored?
Refer to the documentation applicable to the supplied product. Contact Ascend Research if you need clarification.

Where does Ascend Research ship from?
Orders are dispatched from within Australia.
