GHK-Cu research guide · Updated 24 Oct 2026

What is GHK-Cu?

GHK-Cu is the copper complex of the tripeptide glycyl-L-histidyl-L-lysine (GHK). GHK was first identified in human plasma in the 1970s, and it binds copper strongly, which gives the powder its blue color. It is widely studied in skin and wound research models. It is supplied as a lyophilized powder for in vitro and preclinical laboratory research only.

Full specifications

Sequence: Gly His Lys, copper complex
Length: 3 amino acids plus copper
CAS number: 89030-95-5
Molecular formula: C14H23CuN6O4+
Molecular weight: 402.9 g/mol
Form: Lyophilized powder in a glass vial
Purity standard: 98% or higher (brand listing)
Storage: Minus 20 °C long term. 2 to 8 °C once reconstituted, use within 30 days.

How GHK-Cu is tested

A good GHK-Cu listing comes with a lab report for the exact lot in the vial. These are the results to look for:

Purity (HPLC)
How much of the sample is the compound
Identity (MS or LCMS)
Confirms it is the right molecule
Net content
The real mg in the vial versus the label
Endotoxin (LAL)
Bacterial residue, reported in EU
Sterility
Confirms nothing is growing in the vial
Heavy metals (ICP-MS)
Arsenic, cadmium, lead and mercury

Storage and handling

Lyophilized GHK-Cu is stable at room temperature while it ships. For long term storage keep vials at minus 20 °C. Once reconstituted for laboratory use, store at 2 to 8 °C and use within 30 days.
