Science
Mechanism of Action
GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper complex) is a naturally occurring copper peptide found in human plasma, saliva, and urine. It modulates gene expression, promotes collagen and elastin synthesis, stimulates wound healing, and possesses potent antioxidant and anti-inflammatory properties. It declines with age — from ~200ng/mL at age 20 to ~80ng/mL by age 60.
Benefits
Research Benefits
- Stimulates collagen and elastin production
- Accelerates wound healing and tissue repair

- Improves skin elasticity and reduces fine lines
- Promotes hair growth via follicle stimulation
- Modulates over 4,000 human genes related to healing
Research
Dosage Protocol
Research protocols for topical application typically use 0.05%-3% concentrations. For subcutaneous research, 1-2mg daily is commonly studied. For hair growth research, 3% topical solutions are standard.
