You can buy GHK-Cu from LOOM Peptides, which stocks it in 50 mg and 100 mg lyophilized vials and ships from the USA. Everything LOOM supplies is for in vitro laboratory research — not for human or veterinary use.
GHK-Cu is a copper peptide: the tripeptide glycyl-L-histidyl-L-lysine complexed with copper(II). The copper is coordinated by the histidine imidazole and the peptide backbone, which is what distinguishes GHK-Cu from uncomplexed GHK.
LOOM Peptides sells GHK-Cu in 50 mg and 100 mg lyophilized vials. The listing defaults to the 50 mg format.
The colour comes from the copper(II) coordination complex. A blue tint in the lyophilized powder is a property of the copper peptide rather than an indication of anything about the batch.
Yes — GHK-Cu from LOOM Peptides is independently tested by an accredited third-party laboratory using HPLC for purity and identity. Every peptide we supply is over 99% pure. Certificates of Analysis are published on the product page as testing is completed — review the report before you order. A certificate records the identity, purity and quantity measured for the material supplied, so you can confirm what you received matches what was ordered.
Please refer to your facility's standard operating procedures.

About GHK-Cu
What is GHK-Cu peptide?
GHK-Cu peptide is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, supplied by LOOM Peptides as a blue lyophilized powder for in vitro laboratory use. LOOM supplies the pre-formed copper complex rather than free GHK, so the copper stoichiometry is fixed and documented on the certificate.
How does GHK-Cu work?
In vitro, GHK binds Cu2+ through the histidine imidazole nitrogen, the N-terminal amine and the glycine carbonyl, forming the characteristic blue complex; the copper-peptide chemistry is the readout in most assay work, and it is one of the most cited small peptides in the in vitro literature.
How LOOM tests GHK-Cu
Peptide synthesis and purification, complexation with copper, lyophilization. Independent analysis by HPLC for purity and identity (retention time against a reference standard); certificate at /coa/ghk-cu-50mg-hz-1008-ghk50-01-coa.webp.
