GHK-CU
$60.00
GHK-Cu (known as Copper Peptide) is a triaminopeptide complexed with Cu²⁺ that modulates gene expression—upregulating genes involved in extracellular matrix synthesis (e.g., COL1A1, ELN) and downregulating matrix metalloproteinases (e.g., MMP1). It activates TGF-β and PDGF pathways in dermal fibroblasts, enhances antioxidant defenses via Nrf2-driven transcription, and influences angiogenic signaling through VEGF induction. In in vitro and rodent models, these combined effects accelerate tissue regeneration, dermal remodeling, and anti-inflammatory responses.

Mechanism of action
Extracellular Matrix Remodeling
GHK-Cu upregulates COL1A1, COL3A1, and ELN expression while downregulating MMP1 and MMP9, resulting in enhanced dermal fibroblast-mediated matrix deposition.
Growth Factor Activation
Activates latent TGF-β and increases PDGF-BB release, driving fibroblast proliferation and myofibroblast differentiation for wound contraction.
Antioxidant & Anti-Inflammatory Signaling
Induces Nrf2 nuclear translocation, elevating SOD and catalase activity, and inhibits NF-κB, reducing TNF-α and IL-1β production.
Angiogenesis Promotion
Increases VEGF and FGF-2 secretion from endothelial cells, enhancing capillary sprouting and neovascularization in repair sites
