Characterization

What it is, stated plainly.

What it is

The copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys). The copper ion is coordinated by the imidazole nitrogen of the histidine side chain together with the N-terminal amine and a backbone nitrogen, which is what distinguishes the complex from the free peptide. Published work sits in the extracellular-matrix and copper-transport literature.

How a lot is verified

Identity confirmed by and mass-spec; purity assayed by third-party , with a certificate of analysis published where tested. A lot that misses spec is rejected.

Handling & storage

Supplied as a lyophilized powder. Store at −20°C, desiccated and protected from light. Handled per the receiving laboratory's protocols. Not for human consumption.

Also known asCopper tripeptide-1 · Copper peptide GHK-Cu · Prezatide copper · Copper(II)-GHK

GHK-Cu is a copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys), supplied as a lyophilized powder for laboratory research use only.

In the literature the tripeptide is studied for its copper-binding chemistry and its role in extracellular-matrix and tissue-remodelling research models; the copper ion is coordinated by the peptide backbone and the histidine side chain.

Reported mechanism · literatureDescribed in the research literature as a copper-coordinating tripeptide examined in extracellular-matrix and cytoprotection models; the summary reflects that literature only.

What is GHK-Cu?

GHK-Cu is a copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys). Ouralus supplies it as a lyophilized powder for laboratory research use only, with a third-party HPLC certificate of analysis published where tested.

What is the formula of GHK-Cu?

The neutral 1:1 copper complex is commonly given as C14H22CuN6O4 (molar mass ≈ 401.9 g/mol; PubChem CID 71587328, CAS 89030-95-5). Different protonation-state representations of the same complex appear across databases.

Who can order?

These materials are supplied strictly for laboratory and research use, to purchasers of legal age. They are not supplements, drugs, or foods, and are not for human or animal consumption.

Is GHK-Cu 50 mg legal to buy?

GHK-Cu 50 mg is supplied strictly as a research chemical for laboratory research use only — it is not a drug, supplement, or food, and not for human or animal consumption. It ships to purchasers of legal age for research use. Buyers are responsible for compliance with the laws that apply to research materials in their own jurisdiction.

Is a certificate of analysis provided with GHK-Cu 50 mg?

Yes — each tested lot of GHK-Cu 50 mg ships with a third-party HPLC certificate of analysis from Janoshik, independently verifiable by lot (verify key EP4QIRBYZC47). The current lot assayed 99.846%. We publish the certificate before making any purity claim; this is a research chemical for laboratory use only.
