GHK-Cu Research Guide

Full name: Copper Peptide GHK-Cu (Glycyl-Histidyl-Lysine Copper)

A naturally occurring copper-binding tripeptide that declines with age. Promotes collagen synthesis, wound healing, and has broad regenerative effects on skin, hair follicles, and tissues.

How GHK-Cu Works

Copper delivery enhances antioxidant enzyme activity (SOD), stimulates collagen and glycosaminoglycan synthesis, promotes stem cell activation, and modulates gene expression.

Dosing Protocol

• Typical dose: 1-3 mg topical · 200-500 mcg injectable
• Frequency: Daily (topical) · 3x/week (injectable)
• Duration: 8-12 weeks
• Route: Topical cream/serum or subcutaneous injection

Reported Benefits

• Collagen and elastin synthesis
• Wound healing acceleration
• Skin tightening and remodeling
• Hair follicle stimulation
• Antioxidant protection

Potential Side Effects

• Skin irritation (topical)
• Injection site bruising
• Temporary redness
