Epitalon vs Leuphasyl
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Epitalon
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 →Leuphasyl
Leuphasyl (Pentapeptide-18) is a cosmetic peptide that reduces muscle tension through a mechanism similar to enkephalins. Often combined with Syn-Ake for enhanced anti-wrinkle effects.

| Aspect | Epitalon | Leuphasyl |
|---|---|---|
| Mechanism | Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production and circadian rhythms. | Mimics enkephalin and binds to enkephalin receptors on muscle cells, reducing acetylcholine release and thereby decreasing muscle contraction intensity. |
| Typical Dosage | Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year. | Topical: 3-8% concentration in serums. Often used in combination products with other muscle-relaxing peptides. |
| Administration | Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously. | Topical application to expression lines. Best results with consistent twice-daily use over 8+ weeks. |
| Side Effects | Generally well-tolerated. May affect sleep patterns initially. | Very well-tolerated topically. No significant adverse effects reported at cosmetic concentrations. |
