GHK-Cu

GHK-Cu is a copper peptide made from the natural three-amino-acid peptide GHK bound to copper. It has a long research history in skin, wound repair, collagen, elastin, and tissue remodeling. Researchers study GHK-Cu because copper and peptide signals can affect how skin cells build and organize the material around them. Studies have looked at fibroblasts, collagen, elastin, blood-vessel signals, inflammation, wound repair, skin firmness, fine lines, sun-damaged skin, and hair-follicle biology. That broad skin and repair research is what makes GHK-Cu one of the best-known copper peptides in this category.
