GHK-Cu

Description of GHK-Cu

GHK-Cu is a copper(II) complex of glycyl-L-histidyl-L-lysine (Gly-His-Lys). PubChem associates prezatide copper with CAS 89030-95-5 [2]. Coordination, protonation, counterions and hydration affect how a molecular formula or mass should be interpreted; a GHK reference is not automatically equivalent to every copper–peptide preparation.

Validated salt form, excipients, physical appearance, formulation, and product-specific stability data are not established by the supplied reports.

Overview of Published Research

Maquart and colleagues investigated the tripeptide–copper complex in fibroblast cultures [1]. This is in-vitro evidence about a defined experimental system, not validation of commercial research inventory or evidence of established outcomes in humans.

Copper complexes and extracellular-matrix assays

The study reported stimulation of collagen synthesis independently of changes in cell number [1]. Such an endpoint describes a cell-culture response under the reported conditions. Copper coordination and material characterization are important boundaries when comparing experiments: the supplied report does not establish copper-to-peptide stoichiometry or formulation equivalence.

Evidence and material limitations

A definitive supplied-material molecular mass, counterion and hydration state are not established here. Supplier chromatographic results should not be presented as confirmation of complex stoichiometry, biological activity or the purity of a specific ICU lot.
