Epitalon (Epithalon) is a synthetic tetrapeptide based on the natural peptide epithalamin, produced by the pineal gland. It is primarily studied for its effects on telomerase activation.
Full details →Side-by-Side Comparison
| Aspect | AHK-Cu | Epitalon |
|---|---|---|
| Mechanism | The copper-binding tripeptide stimulates collagen synthesis and may promote hair follicle enlargement. Works similarly to GHK-Cu but may have distinct receptor interactions. | Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production and circadian rhythms. |
| Typical Dosage | Topical: 0.5-2% concentration in serums for skin or scalp applications. Often combined with other growth factors for hair formulations. | Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year. |
| Administration | Topical application to skin or scalp. Can be used with microneedling for enhanced penetration. May cause temporary blue-green tint at high concentrations. | Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously. |
| Side Effects | Generally well-tolerated. May cause skin irritation in sensitive individuals. Temporary discoloration possible. | Generally well-tolerated. May affect sleep patterns initially. |
