About this peptide

GHK-CU

GHK-Cu is supplied as a laboratory research material for qualified analytical and in-vitro research environments.

01 Copper-chelated tripeptide

Glycyl-L-histidyl-L-lysine holding a single copper(II) ion, at 403.9 g/mol.
02 Colour is the complex

The blue tint of the powder, and of the solution once reconstituted, comes from the chelated copper. A colourless vial suggests the free peptide rather than the complex.
03 Distinct from the free peptide

The uncomplexed tripeptide is a separate substance — CAS 49557-75-7, 340.38 g/mol. Check the CAS on the certificate if a protocol specifies one or the other.
04 Research material

Supplied lyophilised at −20°C with a batch certificate of analysis, for analytical and in-vitro use only.

FAQ

Before you order.

Anything not covered here, ask us directly — replies within one working day.

Is a COA included with my order?

Yes. Every vial ships with a certificate of analysis tied to the lot number printed on its label, covering identity by mass spectrometry and purity by HPLC. Retained samples are held so a batch can be re-tested.

How is the product shipped?

Lyophilised powder is stable at ambient temperature in transit and ships in discreet, tracked packaging. UK and EU orders are sent on a priority service; international destinations are quoted at checkout.

How should the vial be stored on arrival?

Keep it sealed at −20°C, protected from light. Lyophilised material is stable for months under those conditions. Once reconstituted, store at 2–8°C and use within the window stated on the certificate of analysis.

Who is this product for?

Qualified researchers and laboratories only. It is supplied strictly as an analytical and in-vitro research material, and is not a medicine, a supplement or a veterinary product.

Why is the powder blue?

The copper(II) ion held by the tripeptide absorbs in the red end of the spectrum, which is what gives both the lyophilised powder and the reconstituted solution their blue to blue-violet colour. It is a property of the complex, not a contaminant.
