Epitalon

Research compound. This is not a dietary supplement. Unless it is identified as an approved prescription drug, it is not approved by the FDA for human use. This page summarizes published research for education only; we do not sell it or link to sellers.

Epitalon. A short tetrapeptide studied in Russia for telomerase activation, sleep regulation, and pineal-gland function.

How it works. Reported to upregulate telomerase activity in some cell lines and to support melatonin rhythm via the pineal gland.

What the research supports. 3 graded claims. Strongest: Reported improvements in sleep onset and depth (preclinical).

Hormonal impact. Effects on Melatonin, Cortisol rhythm, Sex hormones (LH/FSH), Telomerase.

Side effects and interactions. 1 medication interaction listed. Serious: Unknown long-term safety; telomerase activation has theoretical cancer concerns.

Stacking. Pairs well with Sleep hygiene practices. Avoid combining with Active malignancy.

Common forms. Available as Subcutaneous injection, Intranasal (research).

Community. Experiences from people who have tried Epitalon. Anecdotes are not medical advice.

What it is

Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) modeled after epithalamin, a polypeptide complex extracted from the pineal gland.

Also called

EpithalonEpithalamin

How it works

Reported to upregulate telomerase activity in some cell lines and to support melatonin rhythm via the pineal gland.

Pathways

  • Telomerase activation (in vitro)
  • Pineal melatonin regulation

Effects

  • +Circadian rhythm and melatonin output supports
  • ↑Telomerase activity (preclinical) increases
  • +Antioxidant capacity (animal studies) supports

Strong: consistent results across large trials or meta-analyses. Moderate: several trials, mostly positive. Limited: small or mixed studies. Preclinical: animal or cell research only.
