GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys). GHK occurs naturally in plasma, saliva and urine and binds copper(II) ions with high affinity, forming the blue complex supplied here.

Research interest centres on extracellular matrix biology: collagen and glycosaminoglycan synthesis, fibroblast activity, and the broad changes in gene expression reported in cultured cells exposed to GHK. It is also used in studies of copper transport and copper-dependent enzymes.

Each vial contains 50 or 100 mg of GHK-Cu (select a size above) as a lyophilized powder. Reconstitute with bacteriostatic water (sold separately) before laboratory use. The COA & Testing tab lists the tested batch, with links to verify it on COA Coalition and with the laboratory.

How to verify

  1. Click “Verify on COA Coalition” or scan the QR code to open our coalition profile, listed under the business name: Natura Peptides
  2. Find this COA by its search code on the profile and open the document.
  3. To check with the laboratory directly, click “Verify at the lab” and enter the search code in the lab's COA lookup.
  4. Compare the product, strength and lot on the COA with your vial label. If anything does not match, contact us before use in research.
Why isn’t our name printed on the COA? As a COA Coalition member, batch samples are submitted to the laboratory through the coalition, so the lab lists the coalition as its client. Member vendors are registered with the coalition instead of being printed on the PDF — that is why you confirm us by entering our business name on the coalition's verify page or by finding the COA on our coalition profile.
