Epitalon Peptide
Pineal peptide researched for telomere and circadian support.
What is Epitalon?
Epitalon is a longevity · circadian peptide studied for telomerase activity (in vitro) and circadian and melatonin rhythm. Below is an educational overview of Epitalon peptide benefits, mechanism, common research protocols, dosage references, and known side effects.
Epitalon in plain language
Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) based on the pineal peptide epithalamin, studied primarily in longevity and circadian research.
- Classification: research peptide — not FDA-approved and not available through regulated pharmacies.
- Proposed mechanism: reported effects on telomerase activity and pineal melatonin rhythm in cell and animal studies.
- Most-studied areas: aging biomarkers, circadian rhythm, and antioxidant signaling.
- Evidence level: largely older Russian-language studies plus in vitro work; independent replication is limited.
- No validated human dosing protocol or long-term safety data exist.
- Frequently discussed alongside: MOTS-c and NAD+ precursors in longevity-focused research.

Epitalon Mechanism of Action
A synthetic tetrapeptide (Ala-Glu-Asp-Gly) modeled on epithalamin, a pineal gland extract. Research from Russian gerontology groups has examined effects on telomerase activity, melatonin rhythm, and lifespan in rodent and limited human cohorts.
