GHK-Cu
Copper Peptide GHK-Cu
A naturally occurring copper peptide with remarkable anti-aging, hair growth, and skin rejuvenation properties. Known for reversing grey hair and improving skin elasticity.
How GHK-Cu Works
GHK-Cu is a tripeptide naturally present in human plasma, saliva, and urine that declines significantly with age. It functions as a copper-binding peptide that activates tissue remodeling by stimulating collagen and glycosaminoglycan synthesis in skin fibroblasts. GHK-Cu also acts as a potent gene expression modulator, influencing over 4,000 human genes — upregulating those involved in tissue repair and stem cell activity while downregulating inflammatory and tissue-destructive genes.
📊 Evidence by Outcome
Widely reported hair darkening within 1-2 weeks. Community data shows significant hair regrowth with sustained use.

Side Effects & Safety
Interactions & Contraindications
Drug Interactions
- •May interact with immunosuppressants (modulates immune signaling)
- •Theoretical interaction with anti-cancer therapies (affects gene expression related to cell growth)
- •No well-documented drug interactions in clinical literature
Supplement Interactions
- •Synergistic with vitamin C for collagen synthesis
- •Compatible with retinoids for skin rejuvenation (apply at different times to avoid irritation)
- •Works well alongside BPC-157 for systemic tissue repair
Food & Timing
- •No known food interactions
- •Injectable form best taken independent of meals
- •Topical application not affected by food
Who Should Avoid
- •Active cancer (GHK-Cu modulates gene expression related to cell growth and angiogenesis)
- •Pregnancy and breastfeeding (insufficient safety data)
- •Children under 18
- •Known copper sensitivity or Wilson's disease

Frequently Asked Questions
Yes, GHK-Cu is available in the UAE both as topical serums (widely sold in skincare clinics) and as injectable peptide through compounding pharmacies and wellness clinics in Dubai.
For skin applications, visible improvements in texture and tone typically appear in 4-8 weeks. For hair regrowth, 3-6 months of consistent use is generally needed. Injectable protocols for systemic anti-aging may take 8-12 weeks.
Topical GHK-Cu is excellent for localized skin and hair benefits with virtually no systemic side effects. Injectable GHK-Cu provides systemic benefits including gene expression modulation and broader anti-aging effects. Many users combine both.
Yes, but apply them at different times (e.g., GHK-Cu in the morning, retinol at night) to avoid potential irritation. They have complementary mechanisms for skin rejuvenation.
