GHK-Cu research in the UK
GHK-Cu is one of the most published copper-binding peptides in the dermatology and regenerative-medicine literature, with documented activity across collagen synthesis, antioxidant pathways and gene-expression modulation. UK academic and cosmetic-formulation research groups source the compound for in-vitro skin, wound and gene-expression model work.
Peptx GHK-Cu is sourced from vetted manufacturers (independent ISO 17025 lab testing) and is HPLC and Mass Spectrometry tested at the manufacturer (documentation not shipped with orders). Independent ISO 17025 retesting is supported by a 14-day purity refund policy.
UK domestic dispatch means no customs forms, no import VAT and no border delays. Prices display in GBP, converted live from wholesale USD source pricing.

Independent purity verification
Peptx stock is backed by manufacturer HPLC and Mass Spectrometry data plus independent spot checks, at typically 99%+ purity (HPLC); the guaranteed minimum varies by compound. Our suppliers are not chosen on a single rating. We weigh independent testing at accredited ISO 17025 labs.
Independent laboratories test our material on a rolling programme: random quality-control checks, tests on stock we buy in, and testing as part of vetting every new supplier. Certificates are published openly in the COA Library rather than issued per order, so you can read the laboratory's report before ordering, not after. Independent verification is expanding across the catalogue, with further tests in progress across September and October. If you want your specific batch independently checked, send a sample to an accredited ISO 17025 lab (see our Recommended Labs at /testing): a result you commission yourself carries more weight than one handed to you by a seller. Any independent lab result below the product's stated guaranteed minimum purity, or a sealed-vial endotoxin or sterility failure, is refunded or re-shipped within 14 days.
All compounds are supplied as sterile lyophilised powder in sealed vials, packed with desiccant, and stored at controlled temperature throughout the supply chain.

GHK-Cu UK FAQ
Is GHK-Cu legal to buy in the UK for research?
GHK-Cu is not a controlled substance under the UK Misuse of Drugs Act 1971 and can legally be sold for in-vitro laboratory and cosmetic-formulation research. All products supplied by Peptx are strictly for in-vitro laboratory research and are NOT for human or animal consumption.
What is the difference between GHK and GHK-Cu?
GHK is the bare glycyl-histidyl-lysine tripeptide. GHK-Cu is the copper-bound complex, which the literature identifies as the bioactive form for most of the published collagen, gene-expression and antioxidant findings.
How long does UK delivery take?
Most UK orders are dispatched within 24 to 48 hours of payment confirmation and delivered in 3 to 5 working days using tracked Royal Mail or DPD services.
What purity is Peptx GHK-Cu?
All Peptx GHK-Cu is guaranteed at 99%+ purity by HPLC and Mass Spectrometry. A 14-day refund window applies if an independent ISO 17025 lab report shows purity below the advertised level.
What is the minimum order quantity?
Minimum order is 1 box of 10 vials. We supply primarily to research laboratories and group buys rather than individual consumers.
