What is GHK-Cu?
In experimental studies, GHK-Cu has been shown to promote collagen and glycosaminoglycan synthesis, enhance angiogenesis, and modulate gene expression associated with skin repair and anti-inflammatory responses. Its strong copper affinity also allows it to act as a safe copper transporter in biological systems, supporting antioxidant defenses and cellular metabolism.
Chemical Structure of GHK-Cu
GHK-Cu has the molecular formula C₁₄H₂₃CuN₆O₄ and a molecular weight of approximately 401.91 g/mol.
It is a tripeptide–copper(II) complex where the copper ion coordinates with the nitrogen atoms of the glycine and histidine residues and the oxygen of lysine, forming a square-pyramidal structure. This arrangement stabilizes the copper ion and prevents oxidative damage.
The peptide sequence (Gly-His-Lys) confers high biological compatibility and efficient tissue penetration, making GHK-Cu a widely studied compound in biochemical and dermatological research models.
What Are the Effects of GHK-Cu?
-
Wound Healing & Regeneration: In preclinical models, GHK-Cu enhances fibroblast migration, collagen deposition, and angiogenesis, accelerating tissue repair and improving extracellular matrix quality.
-
Anti-Inflammatory & Antioxidant Activity: It upregulates antioxidant enzymes such as superoxide dismutase (SOD) and catalase while reducing inflammatory cytokines, protecting cells from oxidative damage.
-
Gene Modulation: Studies show GHK-Cu influences over 400 human genes involved in growth, repair, and immune regulation, including pathways related to cell adhesion and proteostasis.
-
Skin & Hair Research: Laboratory investigations demonstrate improved skin elasticity, reduced inflammatory markers, and stimulation of hair follicle activity, making GHK-Cu a focus of cosmetic and dermatological research.
