GHK-Cu is a naturally occurring copper-binding tripeptide composed of glycine, histidine, and lysine complexed with copper. Originally identified in human plasma, GHK-Cu has become widely studied in laboratory research involving cellular signaling, extracellular matrix activity, tissue remodeling, and mechanisms associated with cellular maintenance.

GHK-Cu research has explored its relationship with collagen and extracellular matrix-related processes, as well as signaling pathways involved in cellular migration and tissue response. Researchers have investigated how its ability to bind and transport copper may influence biological processes that depend upon this essential trace element.

Another significant area of GHK-Cu research involves gene expression, oxidative processes, and cellular signaling. Laboratory studies have examined the compound in experimental models involving cellular stress, inflammatory pathways, and age-associated changes in tissue biology.

GHK-Cu has a molecular weight of approximately 403.9 g/mol as the copper complex. This 50mg formulation is supplied in a nasal research format for controlled laboratory investigation involving copper-peptide biology, cellular signaling, and related biochemical pathways.
