GHK-Cu 50mg

What is GHK-Cu (Copper Peptide)?

GHK-Cu is a naturally occurring tripeptide — glycine-histidine-lysine — that binds copper ions. It was first isolated from human plasma in the 1970s and has since been studied extensively for its biological effects on tissue regeneration, wound healing, and anti-aging. Concentrations in the body are highest in youth and decline significantly with age: abundant in the 20s, minimal by age 60.

How It Works

GHK-Cu activates a broad range of biological processes. It stimulates collagen, elastin, and glycosaminoglycan synthesis — the structural proteins that give skin, joints, and connective tissue their integrity and elasticity. It also acts as a copper transporter, regulating the availability of copper in tissues where it is needed for enzymatic reactions. Research suggests it modulates gene expression in ways that promote healing and reduce oxidative stress.

Key Benefits

GHK-Cu has been studied for skin rejuvenation, wound healing acceleration, hair follicle stimulation, and connective tissue repair. Dermatological research suggests it increases skin thickness and elasticity, reduces fine lines, and improves skin density over time. In hair studies, it appears to support follicle health and growth phase extension. Beyond aesthetics, it is studied for its role in gut healing and systemic tissue remodeling — making it relevant for both cosmetic and recovery applications.

What to Expect

GHK-Cu is used both topically and via subcutaneous injection, depending on the indication. Injectable administration provides systemic delivery for whole-body tissue support. Skin and hair benefits typically emerge over 8–16 weeks of consistent use. It is often included in anti-aging protocols alongside NAD+ and MOTS-c for comprehensive cellular support. As with all peptides, results vary by individual and protocol design.
