Epitalon vs Epithalamin
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 →Epithalamin
Epithalamin is a natural peptide extract from the pineal gland. It is the precursor compound from which the synthetic Epitalon was derived. Known for anti-aging and telomerase-activating properties.

| Aspect | Epitalon | Epithalamin |
|---|---|---|
| Dose Range | 5 mg–10 mg | 5 mg–10 mg |
| Frequency | 1x daily | 1x daily |
| Cycle Length | 2–3 weeks | 1–2 weeks |
| Route | subcutaneous | intramuscular |
| Mechanism | Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production and circadian rhythms. | Similar to Epitalon, it stimulates telomerase production and may help maintain telomere length. Also regulates melatonin synthesis and circadian rhythms. |
| Typical Dosage | Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year. | Research dosing: 10-20mg daily for 10-20 day cycles. Often administered 1-3 times per year in long-term protocols. |
| Administration | Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously. | Intramuscular or subcutaneous injection. Natural extract may have more variable composition than synthetic Epitalon. |
| Side Effects | Generally well-tolerated. May affect sleep patterns initially. | Generally well-tolerated. May affect sleep patterns. Less characterized than synthetic Epitalon. |
