Product Information

Your Skin Made This. Now It Makes Less of It Every Year.

GHK-Cu (50mg) is available in Australia through Aus Peptide Supply with fast domestic shipping to all states and territories.

GHK-Cu is a copper peptide that your body produces naturally — and the amount it makes drops dramatically with age. At 20 you have roughly 200 ng/mL in your plasma. By 60 that's fallen to around 80 ng/mL. Researchers believe this decline directly contributes to the loss of skin thickness, elasticity, and the body's ability to repair itself as we age. GHK-Cu has one of the broadest activity profiles of any anti-ageing peptide in the literature — studied for collagen production, skin renewal, wound healing, inflammation, and even resetting which genes are switched on or off in ageing tissue.

It's the active ingredient behind many high-end skincare serums — but in those products it's used topically at very low concentrations. Researchers studying the compound at meaningful concentrations work with the lyophilized peptide directly.

What GHK-Cu Is Used For

  • Collagen & Skin Firming — Stimulates collagen and elastin production — the structural proteins that give skin its firmness, smoothness, and elasticity. Both decline with age; GHK-Cu is studied to reverse that
  • Wound Healing & Skin Repair — Accelerates the repair of damaged skin and tissue, with research across multiple wound healing models showing consistently faster recovery
  • Anti-Ageing at the Gene Level — Research suggests GHK-Cu can influence the activity of over 4,000 human genes — switching on repair and renewal pathways and switching off inflammation and ageing-related gene expression
  • Reduced Inflammation — Calms chronic low-grade inflammation, which drives much of the visible and functional decline associated with skin ageing

Supplied as lyophilized powder at ≥98% purity, verified by HPLC and mass spectrometry. 50mg per vial. Fast domestic shipping across Australia, with batch-specific CoA information available in our CoA Library.

Frequently Asked Questions

What is GHK-Cu?
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.
What does GHK-Cu actually do for skin?
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.
How is GHK-Cu different from regular skincare serums?
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.
What does the research show about GHK-Cu?
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.
How do you reconstitute GHK-Cu?
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.
How should GHK-Cu be stored?
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.
