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.

• Solution structure. An early spectroscopy study described how GHK binds copper(II) in solution [1].
• Crystal structure and redox behaviour. X-ray and spectroscopy work compared the copper complexes of GHK and DAHK, which is another copper-binding sequence. The study looked at their structures and how readily the copper is reduced [2].
• Computational chemistry. Theoretical (DFT) studies have modelled the ways copper can bind to GHK [3].
• A tool for protein crystallography. GHK has been used as a short copper-binding “tag” to help solve protein crystal structures [4].

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.

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