GHK-Cu vs Epithalon
Comprehensive side-by-side comparison of mechanisms, dosing, side effects, and research
Also: Copper Peptide, Glycyl-L-histidyl-L-lysine copper
A naturally occurring copper-binding peptide found in human plasma, saliva, and urine. Widely used in skincare for its wound healing and anti-aging properties.
Also: Epitalon, Epithalone
A tetrapeptide studied for its effects on telomerase activation and potential anti-aging properties. Based on research by Professor Vladimir Khavinson.
Key Comparison Insights
- GHK-Cu is categorized as Skin & Hair, while Epithalon is Bioregulators.
- Epithalon has stronger research evidence (Human Trials) compared to GHK-Cu (Limited Research).
Detailed Comparison
| Attribute | GHK-Cu | Epithalon |
|---|---|---|
| Category | Skin & Hair | Bioregulators |
| FDA Status | Not FDA Approved | Not FDA Approved |
| Clinical Status | Pre I II III IV FDA | Pre I II III IV FDA |
| Mechanism of Action | GHK-Cu stimulates collagen and elastin synthesis, promotes glycosaminoglycan production, supports blood vessel growth, and has antioxidant and anti-inflammatory properties. It remodels damaged tissue and activates wound-healing genes. | Epithalon stimulates telomerase production, potentially slowing or reversing telomere shortening. It may also regulate melatonin production by the pineal gland and has been shown to influence gene expression related to aging. |
| Common Dosing | 1-2 mg daily (injection) or topical Once daily | 5-10 mg daily for 10-20 days Once daily in cycles |
| Administration | Subcutaneous injection or topical application | Subcutaneous or intramuscular injection |
| Typical Duration | Varies by application | 10-20 day cycles |
| Best Time to Take | Evening (for skin/recovery) | Before bed |
Possible Side Effects May vary by individual |
|
|
| Research Summary | Studies demonstrate increased collagen synthesis, improved skin elasticity, reduced fine lines, and accelerated wound healing. Research shows it can reset gene expression to a healthier state and may have systemic anti-aging effects beyond skin. | Russian studies show increased telomerase activity and extended lifespan in animal models. Human studies suggest improved sleep, reduced cortisol, and potential immune benefits. Research quality and Western replication remains limited. |
Frequently Asked Questions: GHK-Cu vs Epithalon
