GHK-Cu50mg

GHK-Cu is a copper-binding tripeptide that occurs naturally in human plasma, where its levels are highest in youth and decline steadily with age. Often called simply the "copper peptide," it's one of the most studied compounds in skin, collagen, and regeneration research.

Research centers on how GHK delivers copper into cells and signals the rebuilding of the skin's support structure, including collagen, elastin, and the broader extracellular matrix, along with antioxidant and wound-repair activity. Most studies focus on skin aging, firmness and hydration, hair follicles, and wound healing.

Its strongest human evidence is topical and cosmetic, where it holds recognized ingredient status, while injectable and other uses rest mainly on laboratory and animal research.
