§ About GHK-Cu

GHK-Cu is the copper complex of the tripeptide glycyl-L-histidyl-L-lysine (GHK). The peptide has a high affinity for copper ions, forming a copper-peptide complex that has been investigated in laboratory, cellular and preclinical research.

Published research has examined GHK and GHK-Cu across areas including extracellular-matrix biology, cellular signalling and tissue-remodelling models. Evidence varies by model and formulation, and findings from topical, cellular or animal research should not automatically be interpreted as established effects in humans. PepDirect supplies GHK-Cu exclusively for laboratory research use.

§ GHK and GHK-Cu

GHK is the copper-free tripeptide glycyl-L-histidyl-L-lysine. GHK-Cu refers to its copper complex. These are related but chemically distinct research entities, so identifiers and evidence should not be treated as interchangeable. Research conducted on GHK alone should not automatically be represented as research on the copper complex, and vice versa.

§ FAQ

What is GHK-Cu?: GHK-Cu is a copper complex formed from the tripeptide GHK (glycyl-L-histidyl-L-lysine) and copper ions. It has been investigated in a range of laboratory and preclinical research settings.
Is GHK the same as GHK-Cu?: No. GHK is the copper-free tripeptide, while GHK-Cu is its copper complex. They are closely related but chemically distinct research entities, and their identifiers and research evidence should not automatically be treated as interchangeable.
Is GHK-Cu a cosmetic product on PepDirect?: No. This PepDirect product is supplied as a laboratory research material and is not marketed as a cosmetic, medicine or product for human or veterinary use.
What amounts of GHK-Cu does PepDirect supply?: PepDirect currently supplies GHK-Cu in the following amounts: 50mg and 100mg. The active selection on this page controls price and stock.
How is PepDirect GHK-Cu tested?: GHK-Cu is tested by HPLC to a purity of ≥ 99.5%. The current lot displayed on this page is TM-2429. A lot-specific Certificate of Analysis is published on the product page before purchase and ships in the box.
Is this intended for human use?: No. All PepDirect products are sold strictly for laboratory and research use only, and are not intended for human or veterinary use, consumption, or any clinical or diagnostic application.
How quickly does PepDirect ship?: Orders placed before 3:00 PM GMT are dispatched the same business day. Orders placed after 3:00 PM GMT are dispatched the next business day, with tracked delivery in 1-2 business days across the UK and EU. Shipping is calculated and shown at checkout based on destination.
Does PepDirect provide a Certificate of Analysis?: Yes. Every lot's COA is published on the product page before it ships, and the same PDF is included in the box.
What is your guarantee?: Same-day replacement on damaged or lost shipments, or a full refund on request, no questions asked.
