Epitalon

Epitalon (also spelled Epithalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from epithalamin, a peptide complex isolated from the pineal gland. It was developed by Russian researcher Vladimir Khavinson and is one of the most-studied 'bioregulator' peptides.

Epitalon is the longevity-research peptide everyone brings up when telomeres come up. Russian studies have followed it for decades for circadian rhythm, melatonin output, and cellular aging endpoints.

Research suggests Epitalon activates telomerase in somatic cells, supporting telomere elongation and replicative capacity. It also appears to normalize pineal melatonin secretion and may influence circadian gene expression. The exact receptor mechanism remains an open research question.

Synthetic pineal peptide. Studied for telomerase activation, sleep regulation, endocrine normalization.

A plain-English read on how much published evidence currently exists for Epitalon. These ratings describe the volume and maturity of the literature — not effectiveness, safety, or suitability for any use.

Current limitations: most compounds in this category are studied in preclinical or small-sample settings. Absence of large controlled human trials is the single biggest limitation to keep in mind when reading any summary of Epitalon.

Lyophilized compounds are supplied as a dry powder. Concentration is simply the total amount in the vial divided by the volume of bacteriostatic water added:

Concentration (mg/mL) = total mg in vial ÷ mL of diluent added

Commonly supplied vial sizes

10mg or 20mg vial

Worked concentration example

10mg + 2mL BAC water → 5mg/mL On U-100 insulin syringe:

• • 100 units = 5mg
• • 200 units = 10mg

Run your own numbers with the reconstitution calculator — it converts vial size and diluent volume into mg/mL and mcg/mL.

The figures below are reported here descriptively, because they are the values most frequently cited in publicly available research literature and reference material. They are not instructions, not a protocol, and not a recommendation. These compounds are supplied for laboratory research use only and are not approved by the FDA for human consumption.

Commonly cited amounts

5–10mg daily subcutaneous for 10–20 days

Commonly cited frequency

Daily during the cycle

Commonly cited study duration

10–20 days, run 1–2× per year

Peptides are supplied freeze-dried because peptide bonds degrade far faster in solution than in a dry state. Understanding storage is part of understanding why the powder form exists at all.

• •Lyophilized powder: stored refrigerated, typically stable for months to years.
• •Reconstituted solution: refrigerated at 2–8°C, generally discussed as stable for roughly 30–60 days.
• •Heat and direct light accelerate degradation — vials are kept cool and dark.
• •Reconstituted material is not re-frozen; ice crystal formation disrupts peptide structure.
• •Bacteriostatic water contains 0.9% benzyl alcohol as a preservative, which is what allows multi-day storage after reconstitution.

• •Telomerase activation and telomere length studies
• •Pineal function and melatonin research
• •Circadian rhythm modulation
• •Lifespan studies in rodents
• •Comparison with FOXO4-DRI and other longevity peptides

A staple of longevity, biohacker, and Khavinson-bioregulator communities. Common protocol discussion: short 10–20 day cycles, often 1–2x per year. Debate centers on the gap between strong Russian literature and limited Western replication.

Often stacked with other Khavinson bioregulators (Thymalin, Pinealon) in longevity research. Sometimes paired with NAD+ precursors and senolytics.
