GHK-Cu: Copper Peptide, Skin Regeneration and the Science Behind It

GHK-Cu is a naturally occurring tripeptide-copper complex whose concentration declines with age — tracking closely with the deterioration of tissue repair capacity, collagen synthesis, and antioxidant defence that characterises skin and systemic ageing.

GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring tripeptide-copper complex found in human plasma, saliva, and urine. Its concentration declines with age — from approximately 200 nanograms per millilitre in youth to 80 ng/mL by the age of 60. That decline tracks closely with the deterioration of tissue repair capacity, collagen synthesis, and antioxidant defence that characterises skin and systemic ageing.

Mechanism of Action

GHK-Cu is a potent modulator of gene expression. Research has identified it as capable of activating over 300 genes related to tissue remodelling, including those governing collagen and elastin synthesis, metalloproteinase regulation, stem cell mobilisation, and antioxidant enzyme activity. It also modulates TGF-beta signalling, which is central to scar formation and wound repair. Unlike peptides that act through a single receptor, GHK-Cu functions as a broad biological signal for tissue maintenance.

Clinical Applications

GHK-Cu is used both topically and subcutaneously, depending on the goal. Topical application is well-established for skin texture improvement, wrinkle reduction, and wound healing. Subcutaneous injection extends its reach to systemic tissue maintenance — supporting hair follicle health, wound healing at internal sites, and broader regenerative applications. It is a component of the GLOW Stack (with TB-500 and BPC-157) for patients with combined regenerative goals.

• Available formats: Vial, Pen, Nasal Spray
• Topical use: established for skin rejuvenation and collagen support
• Subcutaneous use: systemic tissue maintenance and repair
• Key component of the GLOW Stack

GHK-Cu is available in three formats through UAE Peptide Clinic. Your physician will determine whether topical, subcutaneous, or a combination approach best fits your regenerative goals. Explore the protocol at /peptides/ghk-cu or book a consultation at /book.
