GHK-Cu
Copper Peptide GHK-Cu
GHK-Cu is a naturally occurring copper complex of the tripeptide glycyl-L-histidyl-L-lysine. It has extensive research supporting its role in wound healing, skin regeneration, and anti-aging effects. GHK-Cu levels decline with age, which has led to interest in supplementation.

Topical vs Injectable GHK-Cu: Application Guide
GHK-Cu is unique among peptides because it is effective through both topical and injectable routes. The optimal approach depends on your research target.
Route Comparison
| Factor | Topical (Cream/Serum) | Injectable (SubQ) |
|---|---|---|
| Best for | Skin aging, wrinkles, hair follicles | Systemic tissue remodeling, wound healing |
| Concentration | 0.1-2% in carrier base | 1-2 mg per injection |
| Frequency | Daily application | 2-3x weekly |
| Penetration | Dermal layers only | Full systemic distribution |
| Evidence base | Strong for dermal outcomes | Strong for systemic gene activation |
| Convenience | Non-invasive, easy to use | Requires reconstitution and injection |
Topical GHK-Cu is well-established in cosmetic research for stimulating collagen and elastin synthesis in the skin. Injectable GHK-Cu is preferred when researchers target systemic gene expression changes across multiple organ systems.
Potential Side Effects
- Generally very well tolerated
- Mild skin irritation (topical)
- Injection site reactions
Storage Requirements
Store at 2-8°C. Protect from light.

Frequently Asked Questions
What is GHK-Cu?
GHK-Cu is a naturally occurring copper complex of the tripeptide glycyl-L-histidyl-L-lysine with extensive research supporting its role in wound healing, skin regeneration, and anti-aging. GHK-Cu levels naturally decline with age, which has spurred significant interest in its supplementation for research purposes.
What are the potential research benefits of GHK-Cu?
Research suggests GHK-Cu may improve skin elasticity, reduce wrinkles, enhance wound healing, and stimulate hair follicle growth. It achieves these effects by stimulating collagen and elastin synthesis, promoting angiogenesis, and activating genes associated with tissue remodeling.
How is GHK-Cu typically dosed in research?
GHK-Cu is typically used at 1-2 mg via subcutaneous injection two to three times weekly, or applied topically in cream or serum form daily. Research cycles generally span 8-12 weeks, with topical application being the most common route.
What are the side effects of GHK-Cu?
GHK-Cu is generally very well tolerated in research settings. Potential side effects are minimal and may include mild skin irritation with topical use and injection site reactions with injectable administration.
How should GHK-Cu be stored?
GHK-Cu should be stored at 2-8°C and protected from light to preserve its copper-peptide complex integrity. Proper storage conditions are essential for maintaining its purity and biological activity.
