Epitalon (also spelled Epithalon or Epithalone; sequence Ala-Glu-Asp-Gly, "AEDG") is a synthetic tetrapeptide studied in longevity and anti-ageing research. It is a lab-made version of a peptide originally isolated from the pineal gland. Researchers study it mainly for two reasons: its reported ability to activate telomerase (the enzyme that maintains the protective caps on the ends of chromosomes) and its effect on pineal gland function and melatonin rhythm.

Unlike the weekly metabolic peptides, epitalon is typically studied in short daily courses — for example 5–10 mg per day for 10–20 days, repeated a few times per year. This guide covers that course structure, reconstitution of the 10 mg vial, and what the evidence does and does not show. It is an educational reference, not medical advice.

Epitalon is studied as short, repeated courses rather than a continuous daily peptide. The idea in the research literature is that the peptide acts as a signal that shifts gene expression, so a defined course is followed by a long break before the next one.

Common Research Course Patterns

LA LAB stocks epitalon as a 10 mg vial. Reconstitute with 3.0 mL bacteriostatic water for a concentration of 3.33 mg/mL. Read across the row for your daily dose.

Step-by-Step Reconstitution

Epitalon is a peptide bioregulator — the research idea is that very short peptides can bind DNA and influence which genes are switched on. Two mechanisms dominate the literature.

Telomerase Activation

Cell-culture studies (Khavinson and colleagues) reported that epitalon can induce telomerase activity, the enzyme that rebuilds telomeres — the protective caps on the ends of chromosomes that shorten with each cell division. Longer telomere maintenance is the headline reason epitalon is studied in ageing research. This is a laboratory finding, not a proven human anti-ageing effect.

Pineal Gland & Melatonin Regulation

Epitalon is derived from epithalamin, a pineal-gland peptide preparation. Research suggests it helps normalise melatonin secretion and circadian rhythm, particularly where the pineal gland's output has declined with age. Reported downstream effects include improved sleep-wake rhythm and antioxidant activity.

Because it acts as a signalling peptide rather than a circulating hormone, epitalon's plasma half-life is very short (minutes). That is why it is studied as daily courses — the effect is attributed to gene-expression changes, not to a sustained blood level.

In the published research, epitalon has generally been reported as well tolerated, with few adverse effects noted at the doses studied. However, the evidence base is the key caveat, not the side-effect profile.

• Most human data comes from a small number of Russian research groups over long follow-up; large independent, placebo-controlled human trials are lacking.
• Reported effects (telomere/telomerase, mortality reduction in elderly cohorts) have not been broadly replicated by independent Western trials.
• Long-term safety of repeated telomerase activation is not fully characterised — a theoretical concern raised in the wider literature.
• As a research-grade peptide, purity and correct reconstitution matter; COA verification is a buyer-side responsibility.
• Not studied in pregnancy or breastfeeding — should be avoided in those situations.

Epitalon is not approved as a medicine by the FDA, EMA, SAHPRA, or other major regulators. It is sold as a research-grade peptide for laboratory use only and is not intended for human consumption. Buyers are responsible for COA verification, correct storage, and compliance with local research regulations.
