Description What is GHK-Cu? GHK-Cu (Glycyl-L-Histidyl-L-Lysine:Copper) is a naturally occurring tripeptide that binds to copper. It was first identified in human plasma in 1973 by Dr. Loren Pickart, who noticed that older blood lost its ability to stimulate tissue repair compared to younger blood — and traced the difference back to this small peptide-copper complex. Since then, GHK-Cu has become one of the most extensively studied peptides in skin science, wound healing, and anti-aging research. Its ability to influence the expression of over 4,000 genes — many involved in tissue repair and regeneration — has made it a uniquely interesting compound. What Researchers Are Exploring Skin Regeneration & Anti-Aging GHK-Cu is best known for its role in skin research. Studies have shown it stimulates collagen and elastin production, tightens skin, improves skin firmness, and reduces fine lines and wrinkles in research models. It’s also been shown to increase skin thickness and improve overall skin quality — making it one of the most studied anti-aging peptides. Wound Healing Research has consistently demonstrated GHK-Cu’s ability to accelerate wound healing. It promotes the formation of new blood vessels (angiogenesis), attracts immune cells to wound sites, and stimulates the production of structural proteins needed for tissue repair. Hair Growth Research Studies have explored GHK-Cu’s potential to stimulate hair growth by increasing follicle size and activity. Research suggests it may influence hair follicle cells in ways that promote thicker, healthier hair growth — an area that has drawn significant interest. Antioxidant & Anti-Inflammatory Research GHK-Cu has demonstrated strong antioxidant properties in research, and studies have explored its ability to reduce inflammation and protect cells from oxidative damage — mechanisms relevant to aging, tissue degeneration, and recovery research. Worth Noting GHK-Cu’s natural presence in the human body — combined with its remarkable ability to influence thousands of genes involved in repair and regeneration — makes it a uniquely well-supported research compound. Levels naturally decline with age, which has fuelled interest in whether supplementation can reverse age-related tissue changes. For research use only. Not intended for human consumption.
