GHK-Cu
Also known as: Copper Peptide, Glycyl-L-histidyl-L-lysine Copper, GHK Copper Tripeptide
GHK-Cu is a naturally occurring copper complex that declines with age. It is one of the most studied anti-aging peptides, known for powerful skin rejuvenation, wound healing, and tissue remodeling effects.

Key Benefits
- Reduces wrinkles and fine lines
- Improves skin firmness and elasticity
- Accelerates wound healing
- Reduces inflammation and oxidative damage
- Promotes hair growth and thickness
- Supports collagen and elastin production
- May improve overall skin health and appearance
- Resets aged fibroblast behavior
- Anti-fibrotic — reduces scar tissue formation
Mechanism of Action
GHK-Cu activates tissue remodeling by modulating gene expression, promoting collagen and glycosaminoglycan synthesis, and enhancing angiogenesis. It influences over 4,000 human genes, shifting many toward a younger gene expression pattern. It also has potent antioxidant and anti-inflammatory effects, and may 'reset' aged fibroblasts to behave more like younger cells.
Dosing Protocols
