GHK-Cu Copper Peptide: What It Is, Identity, COA and Storage (RUO)

Key takeaways

GHK Cu peptide Canada is a laboratory documentation topic for research peptides Canada buyers who need clear identity, COA, and Canada sourcing records before adding a reagent to a controlled lab workflow.

Hermetica Research Labs lists copper peptide GHK-Cu as a Research Use Only reagent line for Canadian laboratories. The compound identity is the Gly-His-Lys copper complex, supplied as lyophilized material for documentation-led analytical work only. It is not for human or veterinary use, and buyers must be 21+.

Copper peptide GHK-Cu SKU line

The active catalogue pages for this line are:

• GHK-Cu 50mg
• GHK-Cu 100mg

Both pages should be checked for the product name, vial size, SKU, CAS field, form, storage statement, purity field, and certificate link where published. Broader catalogue navigation is available through the shop, and the existing Canada buy path is documented at Buy GHK-Cu Canada.

Identity and lot-matched COA path

A Canadian lab should compare the vial label with the certificate record before filing purchase documentation. The fields to check include compound name, nominal fill mass, lot identifier, physical form, purity method, issuing laboratory, and any accession or report reference. Published certificates are listed on the COA index.

Additional GHK-Cu sourcing context is available at Buy GHK-Cu Canada. For certificate reading, use the RUO COA checklist at How to Read a RUO Certificate of Analysis, plus the existing Janoshik peptide COA checklist and Freedom Diagnostics peptide COA verification references.

What is GHK-Cu?

GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys). The peptide part, GHK, binds a copper ion through the histidine side chain, the glycine amino group and backbone nitrogens, giving a blue lyophilized material. It is often called a copper peptide, and GHK-Cu is the form most commonly listed by research suppliers. For identity work, the catalogue fields that matter are listed below.

Because the copper is part of the compound, a GHK-Cu certificate should make clear whether its mass and purity figures refer to the free peptide or the copper complex. Record which one the report describes.

GHK Cu peptide in Canada: buyer checks

A Canadian laboratory buying GHK-Cu should check four things: the CAS and sequence on the product page match the vial label; the lot on the certificate is the lot on the vial; the purity method (HPLC, with or without MS) is stated; and the issuing laboratory's report number can be checked on that laboratory's own system. The GHK-Cu COA notes walk through the published certificate, and GHK-Cu vs BPC-157 compares the two identity records side by side.

Canada shipping documentation

Hermetica ships within Canada only. Current catalogue shipping is $15.00 CAD per order, with free shipping on orders of $150.00 CAD or more. These are logistics terms for RUO laboratory procurement records and do not change the Research Use Only status of the material.

GHK-Cu copper peptide: how the copper binds

Pickart et al. (1980) found that during isolation the plasma tripeptide co-purified with roughly equimolar copper, and reported that it readily forms complexes with copper(II). They noted a similarity between the tripeptide and copper-transport sites on albumin, where copper is bound by a histidine next to a basic residue. That is why the catalogue lists GHK-Cu as a copper complex rather than a free peptide, and why the 1:1 copper content is part of its identity.

Pickart and Margolina (2018) date the discovery of GHK to 1973 and report plasma GHK of about 200 ng/mL (around 10⁻⁷ M) at age 20, declining to about 80 ng/mL by age 60. Those are measurements of the naturally occurring peptide, not of any supplied reagent.

FAQ

What is GHK-Cu copper peptide?

The copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys). Pickart et al. (1980) reported that the plasma tripeptide readily forms complexes with copper(II).

Where does GHK come from?

GHK was first isolated from human plasma, with its discovery dated to 1973. Pickart and Margolina (2018) report plasma GHK of about 200 ng/mL at age 20, falling to about 80 ng/mL by age 60.

What is the CAS number for GHK-Cu?

CAS 89030-95-5, with the formula listed as C14H24N6O4·Cu, as shown on the Hermetica product pages.

Is GHK-Cu the same as GHK?

No. GHK is the free tripeptide; GHK-Cu is its copper complex. A certificate should state whether its mass and purity refer to the free peptide or the complex.

Does Hermetica give usage guidance for GHK-Cu?

No. GHK-Cu is supplied only as a Research Use Only reagent for in-vitro laboratory work, with no human-use, cosmetic, dosing or therapeutic guidance.
