Storage and handling

Store cold

Sealed vials at 2 to 8 °C (36 to 46 °F), protected from light, as printed on the label. Freeze at −20 °C for long-term storage.

Warm before opening

Let cold vials reach room temperature to prevent condensation on the powder.

Keep sealed

Store in the original sealed vial, dry and away from light, until the material is needed.

Questions

Why is GHK-Cu blue?

The color comes from the copper(II) ion in the complex. A blue to blue-violet powder is expected.

Does GHK-Cu ship with a certificate of analysis?

Yes. Every lot is tested for identity by mass spectrometry and purity by HPLC before release. The lot number on your vial matches its COA in our COA Library.

How should GHK-Cu be stored?

Keep sealed vials refrigerated at 2 to 8 °C (36 to 46 °F) and protected from light, as printed on the label. For long-term storage, freeze at −20 °C. Let a cold vial reach room temperature before opening. See our storage guide.
