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 and shipped tracked from inside Europe.
