Buy GHK-Cu

Buy GHK-Cu – a copper-binding tripeptide of glycine, L-histidine and L-lysine that complexes divalent copper with high affinity. The sequence was originally isolated from human plasma and has since been used in cell-biological and dermatological basic research as a model substance, for example in questions of collagen synthesis in fibroblast cultures, of copper homeostasis and of gene expression in skin models. In the literature GHK-Cu is frequently considered together with the related tripeptide AHK-Cu, which differs only in the exchange of glycine for alanine and shows different binding constants. Peptélia supplies GHK-Cu as a lyophilisate in a vial in two sizes, 50 mg and 70 mg, each with reconstitution and storage details on the product page. The characteristic deep blue appearance of the dissolved substance comes from the bound copper and is not a quality criterion. Every batch is tested in our own laboratory by HPLC for identity and purity and by UV/Vis spectroscopy for content; the batch-specific certificate of analysis can be viewed before purchase – the COA Guide explains how to read it.
