Product information
What it is GHK-Cu combines the naturally occurring tripeptide GHK (glycyl-L-histidyl-L-lysine) with copper. GHK is present in human plasma and other body fluids, although reported levels become lower with age. Research on GHK-Cu goes back several decades. Much of that work has focused on skin and connective tissue, including the processes involved in extracellular matrix remodelling. Its ability to bind copper is central to this research, since copper takes part in a number of biological processes involving tissue structure and cellular signalling. How it works and what the research shows A large part of GHK-Cu research has focused on fibroblasts and the extracellular matrix. Experimental studies have reported changes in collagen and glycosaminoglycan synthesis, along with effects on matrix metalloproteinases involved in tissue remodelling. Elastin, fibroblast proliferation and angiogenesis have also been investigated. The evidence isn't limited to one experimental model, but much of it is still preclinical. A 2026 systematic review brought together 20 studies of GHK-Cu in regenerative and aesthetic research. Eighteen were preclinical, while only two were randomised controlled trials. Across the preclinical studies, researchers reported changes in type I collagen and other extracellular matrix components, metalloproteinase activity, angiogenesis and cellular proliferation. Huma
