GHK-Cu (50mg)

GHK-Cu is a small copper peptide your body produces naturally — and one it makes less of as you age. At 20, your blood carries around 200 ng/mL. By 60, that's dropped to roughly 80 ng/mL. Researchers believe this decline is one of the reasons skin loses its firmness, wounds heal more slowly, and the body's repair systems become less responsive over time. GHK-Cu is studied for its ability to restore some of what's lost — stimulating collagen, accelerating wound healing, and influencing thousands of genes involved in tissue repair and cellular renewal.

GHK-Cu tells your skin cells to get back to work. It signals fibroblasts — the cells responsible for making collagen and elastin — to ramp up production. The result is firmer, thicker skin with better elasticity. It also accelerates wound healing and has been studied for reducing the appearance of fine lines, improving skin texture, and evening out tone. Unlike most skincare ingredients that work on the surface, GHK-Cu operates at the cellular level — which is why researchers take it seriously as more than just a cosmetic ingredient.

Most skincare products apply antioxidants, moisturisers, or exfoliants to the surface of skin. GHK-Cu works differently — it signals your cells directly, influencing gene expression and activating repair pathways your skin already knows how to run. Research suggests it can affect the activity of over 4,000 human genes, switching on repair and renewal while turning down inflammation. A serum can hydrate the outer layer; GHK-Cu is studied to change what the cells underneath are actually doing.

The research base is strong and spans decades. Studies have shown GHK-Cu accelerates wound closure, increases skin thickness and elasticity, stimulates collagen and elastin production, and reduces the visible signs of ageing. At the gene level, it's been shown to influence thousands of pathways involved in repair and inflammation — with some studies suggesting it can shift gene expression in aged tissue back toward a younger state. It's one of the few anti-ageing compounds with a robust enough research profile to be taken seriously by both cosmetic scientists and longevity researchers.

GHK-Cu is supplied as a lyophilized powder and should be reconstituted with bacteriostatic water (BAC water) immediately before use. Inject the BAC water slowly into the vial, directing the stream down the inside wall. Gently swirl to dissolve — do not shake. Once reconstituted, store at 2–8°C and use within 28 days. For a full step-by-step walkthrough, see our complete peptide reconstitution guide.

Store lyophilized GHK-Cu vials at -20°C, away from light and moisture. After reconstitution, refrigerate at 2–8°C and use within 28 days. Do not freeze the reconstituted solution.
