What it is

Epitalon is a synthetic tetrapeptide derived from epithalamin. Studied for telomerase activation and circadian regulation.

Mechanism of action

Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed in Russia by Vladimir Khavinson. It is hypothesized to act on the pineal gland to stimulate telomerase activity and lengthen telomeres, with proposed anti-aging effects. Russian research suggests effects on melatonin secretion, immune function, and longevity. Western clinical evidence is sparse.

Reported uses

Evidence base

Russian clinical research; limited Western trials.

Regulatory status

Compounded — not FDA-approved.

Typical dosing context

Common protocols: 5–10 mg subcutaneous daily for 10–20 day cycles, repeated 1–4 times yearly. Dosing protocols vary widely; the Khavinson research used different cycle structures than what is commonly used in Western longevity-medicine settings.

Dosing in research and clinical-use contexts varies. Specific protocols should always be set by a prescribing clinician, not by patient-direct sources.

Side effects and safety

Generally well-tolerated in available data. Reported side effects are minimal; injection-site reactions are the most common. Long-term safety is not well-characterized in Western clinical settings.

Common stacking protocols

Often layered into broader longevity protocols with NAD+, NMN, GHK-Cu, and lifestyle interventions. Standalone use is also common.

How to access Epitalon

Most peptides discussed on this page are compounded products requiring a prescription from a licensed clinician. Reputable telehealth peptide programs include physician-led oversight, accredited compounding pharmacies, and clear regulatory framing.
