GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine bound to copper) present in human plasma, saliva and urine, with concentrations known to decline with age in the research literature.

GHK-Cu Copper Peptide Research Overview

Q: What documentation comes with SynHealth's GHK-Cu vial?

SynHealth supplies GHK-Cu as a 50mg or 100mg sterile research vial, for laboratory use only. Batch documentation is provided on request wherever we hold it for that lot.

Q: How should GHK-Cu be stored before use?

As a lyophilised research peptide, GHK-Cu should be stored in its sealed vial at -20°C, then reconstituted only immediately before laboratory use and kept refrigerated thereafter.

GHK-Cu is one of the most studied copper-binding peptides in laboratory literature on collagen and matrix biology. This overview covers what it is, why it appears in research models, and how it's sourced and handled for laboratory use in the UK.

What Is GHK-Cu?

GHK-Cu is a naturally occurring tripeptide — glycyl-L-histidyl-L-lysine — bound to a copper ion. It is present in human plasma, saliva and urine, and the research literature has recorded that its natural concentration tends to decline with age. Research-grade GHK-Cu is chemically synthesised to allow consistent purity and batch control for laboratory use.

Why Is GHK-Cu Studied in Laboratory Research?

Published laboratory research has examined GHK-Cu in models relating to collagen and elastin synthesis, and broader matrix-remodelling signalling pathways relevant to dermal and connective-tissue biology. This research is conducted in vitro or in animal models as part of investigation into copper-peptide activity in these pathways. SynHealth makes no cosmetic, therapeutic, or anti-ageing claim, and nothing on this page should be read as suggesting human or animal use outside a licensed research setting.

Purity, Storage & Handling for Laboratory Use

GHK-Cu research peptide is typically supplied as a lyophilised powder in a sealed sterile vial. Standard laboratory handling is to store the sealed vial at -20°C and reconstitute only immediately before use in an assay, using an appropriate diluent. Reconstituted solution is generally kept refrigerated and used within a limited window. GHK-Cu is supplied in a sealed sterile vial in 50mg and 100mg strengths. Batch documentation is provided on request wherever we hold it for that lot.

Sourcing GHK-Cu Research Peptide in the UK

GHK-Cu can be lawfully supplied in the UK as a research chemical, provided it is sold strictly for laboratory and in vitro research, is not marketed for human or veterinary consumption, and is not presented as a medicine or cosmetic. Reputable suppliers should provide purity documentation and clearly label products "for research use only." Buyers are responsible for ensuring their own use complies with all applicable regulations in their jurisdiction and institution.

This page is general research information, not medical, legal, or dosing advice. GHK-Cu products from SynHealth are sold strictly for laboratory and in vitro research use by qualified researchers and institutions — not for human or veterinary consumption.
