GHK-Cu
Also known as: Copper Peptide, GHK-Copper
The Skin Rejuvenation Peptide
The copper peptide for skin health. Boosts collagen, reduces wrinkles, and accelerates wound healing. Popular in skincare.
How It Works
Simple Explanation
Copper-bound peptide that stimulates collagen production and activates skin repair genes.
Technical Details
Increases collagen, elastin, and glycosaminoglycans. Activates wound healing genes, has anti-inflammatory and antioxidant effects.
Pharmacokinetics & Storage
Half-Life
~12-20 hours for copper-peptide complex
Duration in circulation
Storage Requirements
Protect from light and oxidation. Copper can oxidize - blue/green color change indicates degradation. Topical products most stable.
Research Timeline: What Studies Have Observed
Based on clinical trial data and published research. Individual responses may vary significantly.
Weeks 1-2
Research indicates initial activation of wound healing genes. Topical use may show improved skin hydration within days.
Weeks 3-4
Studies document increased collagen synthesis beginning. Some participants reported improved skin texture.
Weeks 6-8
Clinical research shows measurable improvements in skin firmness and fine lines. Hair follicle support effects may emerge.
Weeks 12+
Studies indicate cumulative anti-aging benefits with continued use. Wound healing applications typically show significant improvement by this point.
Benefits
- Increased collagen production
- Reduced fine lines and wrinkles
- Improved skin firmness
- Accelerated wound healing
- Hair follicle support
Potential Side Effects

Known Interactions
Based on clinical research and pharmacological studies. Always consult a healthcare provider about potential interactions.
Vitamin C (topical)
monitorResearch suggests spacing application by 30 minutes when using both topically, as pH differences may affect absorption.
Retinoids
cautionStudies indicate potential for increased skin sensitivity when combined. Some protocols alternate morning/evening use.
AHA/BHA acids
monitorMay cause irritation if layered together. Research protocols typically space applications.
