Epithalon

Tetrapeptide proposed to support telomerase and circadian rhythm.

Not FDA-approvedEvidence

Overview

A four-amino-acid peptide (Ala-Glu-Asp-Gly) developed by Russian gerontologist Vladimir Khavinson. Reports of life-extension in animals and telomerase activation in cells. Human evidence is limited to small Russian studies.

How it works

Proposed to activate telomerase and boost melatonin production from the pineal gland. Mechanisms not confirmed by independent Western research.

Evidence

2/5

Mostly Russian research groups; independent replication lacking.

Easier numbers, add this much water:

Math only: concentration (mg/mL) = vial mg ÷ mL of water; units = dose (mg) ÷ concentration × 100. Always double-check against your own vial label and a clinician. This tool does not recommend a dose.

Reconstitution

Diluent: Bacteriostatic water (0.9% benzyl alcohol) — allows multiple draws from one vial.

  1. Wipe both vial tops with an alcohol swab and let dry.
  2. Draw the diluent, then inject it slowly down the inside wall of the vial — never straight onto the powder.
  3. Swirl gently or let it sit; do not shake. Foam can damage peptides.
  4. Solution should be clear. Cloudy, stringy or discolored = discard.
  5. Common mix: 50 mg + 5 mL = 10 mg/mL (5 mg = 50 units).

Storage

Powder

Freezer / fridge

Keep sealed vial in the freezer (−20 °C) for long-term storage; fridge (2–8 °C) is fine for a few weeks. Keep dry and out of light.

After mixing

~30 days

Refrigerate at 2–8 °C. Never freeze after mixing. Keep upright, capped, and out of light.

Travel

Keep cool

Short trips at room temperature are generally fine for powder; keep mixed vials cold.

Side effects & cautions

Reported side effects

  • Mild headache
  • Injection-site irritation
  • Rare sleep disturbance

Cautions

  • Telomerase activation raises a theoretical cancer concern.
  • Not for use with active cancer.

FAQ

Why cycles instead of daily?

Protocols by its developers use brief courses twice a year, not continuous use.
