Buy GHK-Cu UK: Copper Peptide Research Vials, Prices and Published COA

For in-vitro laboratory research use only. Not for human or veterinary use. Corex Vitality™ supplies research compounds to adults (18+) for laboratory research. Nothing on this page is medical advice.

Corex Vitality™ supplies GHK-Cu as a lyophilised research compound for in-vitro laboratory work in the UK. This page covers what GHK-Cu is, the published chemistry, what to check before you buy, and our current sizes, prices and Certificate of Analysis (COA).

What is GHK-Cu?

GHK is a three-amino-acid peptide (Gly-His-Lys). It binds copper(II) ions tightly, and the copper complex is known as GHK-Cu. The GHK sequence also occurs naturally in blood plasma, where it acts as a copper-binding peptide [2].

Research material is made by peptide synthesis, then complexed with copper and freeze-dried.

What has been studied? (preclinical and chemistry research)

Much of the GHK-Cu literature is about chemistry: how the peptide holds the copper ion and what that complex looks like.

Cell-culture and animal studies on GHK-Cu also exist. Their results cannot be applied to people. Corex Vitality™ makes no claim about any effect of GHK-Cu in the body.

What to check before you buy GHK-Cu in the UK

  1. An open COA. You should be able to open it without logging in. It should show the laboratory, the report number, the test date and the HPLC purity.
  2. A size-matched COA. Ours cover the 50mg size (LDA22160942) and the 100mg size (LDA22160952).
  3. The QR check. Lingda Laboratory COAs carry a QR code that links to the laboratory’s own record. See how to verify a peptide COA.
  4. Claims that match the COA. Our GHK-Cu COAs report HPLC purity and quantity, heavy metals, endotoxin and sterility. They do not include a mass-spectrometry identity test.
  5. Research-only selling. A seller that markets GHK-Cu with cosmetic or health promises is presenting it as a cosmetic or medicine, not as a research compound. Those products have their own UK rules.
  6. UK business details. Look for a company number, a registered address and an ICO registration.

What our GHK-Cu 50mg COA shows

The report is LDA22160942 from Lingda Laboratory. It was tested on 1 September 2026 and issued on 2 September 2026. The laboratory was commissioned by the manufacturer or supplier.

Test Result
HPLC purity >99.68%
Quantity in vial (HPLC) 52.66mg (50mg label)
Heavy metals: lead, cadmium, arsenic, mercury 0.25 / 0.14 / 0.16 / 0.21 ppm (limit ≤10 ppm)
Endotoxin (LAL) 0.13 EU/mg (limit ≤0.50 EU/mg)
Sterility: bacteria, fungi, yeast No growth

The 100mg COA (LDA22160952, tested 2 September 2026) reports HPLC purity >99.75%.
