Epithalon (Epitalon): The Complete Anti-Aging Peptide Guide 2026

Epithalon

Option A

The Telomerase Activator

Epithalon (also spelled Epitalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed by Prof. Vladimir Khavinson at the St. Petersburg Institute of Bioregulation. It's the most extensively studied anti-aging peptide in the world with 40+ years of research. Epithalon activates telomerase, the enzyme that rebuilds telomere length — the primary molecular clock of cellular aging. It also normalizes melatonin production, regulates the hypothalamic-pituitary axis, and has demonstrated life extension in multiple animal models.

Best For
Telomere lengthening
Anti-aging
Improved sleep (melatonin normalization)
Cancer prevention (in studies)
Dosing:5–10 mg/day for 10–20 days, 1–2 times per year. IV or SubQ. Some protocols: 100 mcg/kg/day. Nasal spray: 1–2 mg/day.
Half-life:~Unknown; tissue distribution within minutes
Route:IV (most studied), SubQ injection, intranasal spray

Epitalon

Option B

Same as Epithalon — alternate spelling

Epitalon is the same compound as Epithalon — the alternate spelling comes from different transliterations of the Russian 'Эпиталон.' Both refer to the tetrapeptide Ala-Glu-Asp-Gly (AEDG). There is no chemical difference between products sold as 'Epithalon' vs 'Epitalon' — they are identical molecules.

Best For
All the same applications as Epithalon
Dosing:Identical to Epithalon: 5–10 mg/day for 10–20 days.
Half-life:Identical to Epithalon
Route:IV, SubQ, intranasal

The Verdict

Epithalon and Epitalon are the SAME peptide — just different spellings. When shopping for this compound, both names refer to the tetrapeptide Ala-Glu-Asp-Gly. Focus on purity (>98% HPLC verified) and source quality rather than the spelling. Khavinson's research is the gold standard — look for suppliers who reference his work and provide certificates of analysis.

Don't Stack These ✗

Epithalon stacks well with: Thymalin (immune + anti-aging synergy), Pinealon (cognitive + sleep), and GHK-Cu (tissue repair + anti-aging). The classic Khavinson longevity protocol combines Epithalon + Thymalin + Vilon for comprehensive anti-aging effects.
