GHK-Cu

GHK-Cu is a naturally occurring copper-binding tripeptide complex composed of glycyl-L-histidyl-L-lysine coordinated with divalent copper ions. It has been studied extensively in aesthetic and regenerative research for its relationship to collagen signaling, dermal remodeling, wound response pathways, and extracellular matrix regulation across skin and connective tissue models.

What is GHK-Cu?

Aesthetic · 100mg · 3mL

GHK-Cu is a naturally occurring copper-binding tripeptide complex composed of glycyl-L-histidyl-L-lysine coordinated with divalent copper ions. It has been studied extensively in aesthetic and regenerative research for its relationship to collagen signaling, dermal remodeling, wound response pathways, and extracellular matrix regulation across skin and connective tissue models. Its copper-chelating structure is central to its biological activity and distinguishes it from non-metal-associated signaling peptides within tissue research. Lyophilized powder, 3mL vial. Sold at 100mg per vial. For research use only.

Copper-chelated tripeptide complex. Free GHK alone (C14H24N6O4) is ~340.38 g/mol. CONFIRM Cu-complex vs free form.
