Compound Comparison
GHK-Cu and Glutathione are two research compounds that buyers often weigh up side by side. This page sets them next to each other on the facts that matter when sourcing for the bench in Europe – category, class, chemical formula, vial size, price and current stock – with no claim about what either does.
GHK-Cu is a copper-binding tripeptide (glycyl-L-histidyl-L-lysine), studied in laboratory models of extracellular-matrix remodelling and skin research. Glutathione is an antioxidant tripeptide (gamma-glutamyl-cysteinyl-glycine), studied in laboratory models of cellular redox balance and detoxification pathways. Both are supplied by PowerfullyPeptides strictly for laboratory research use only – not for human or veterinary use – specified to a ≥99% purity target, lot-tracked, and shipped tracked from inside the EU (Ireland).

Research-use answers for buyers comparing GHK-Cu and Glutathione in the EU.
GHK-Cu is a copper-binding tripeptide (glycyl-L-histidyl-L-lysine); it is studied in laboratory models of extracellular-matrix remodelling and skin research. Glutathione is an antioxidant tripeptide (gamma-glutamyl-cysteinyl-glycine); it is studied in laboratory models of cellular redox balance and detoxification pathways. PowerfullyPeptides lists GHK-Cu under Cosmetic Peptides and Glutathione under Cosmetic Peptides, and supplies both strictly for laboratory research use only. This page compares the two on category, class, chemical formula, vial size, price and stock – it makes no claim that either is better or that either has any effect in humans or animals.
No. Both GHK-Cu and Glutathione are supplied exclusively for in-vitro and laboratory research. They are not for human or veterinary use, not for consumption, and nothing on this page is medical guidance or a claim of safety or efficacy.
Both are specified to a ≥99% purity target and are lot-tracked, so a batch can be traced through your records. Independent per-batch Certificate-of-Analysis testing is our published testing standard – see our COA page for how identity and purity are documented.
PowerfullyPeptides supplies both GHK-Cu and Glutathione to research buyers across Europe. Orders ship tracked from inside the EU (Ireland), so shipments to EU destinations cross no customs border, and they are dispatched in 1–2 working days. Both are sold strictly for laboratory research use only.
Yes. Both GHK-Cu and Glutathione are in stock. Add each to your cart from its product page or from the cards on this page, and they ship together in one tracked parcel from inside the EU.
