Summary

Epitalon (also spelled Epithalon or Epithalone) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) modelled on the pineal gland peptide epithalamin. Developed at the St. Petersburg Institute of Bioregulation and Gerontology, it has been studied primarily in Russian research for its effects on telomere length, telomerase activity, and age-related biomarkers. The evidence base is predominantly from animal models and small human studies by a single research group, warranting cautious interpretation.

Mechanism

Epitalon is hypothesised to activate telomerase (telomere reverse transcriptase, TERT), the enzyme that adds repetitive nucleotide sequences to telomere ends. By increasing telomerase activity, epitalon may slow or reverse telomere shortening — a hallmark of cellular ageing. Additionally, as an analogue of the pineal gland peptide epithalamin, epitalon may influence pineal function, including melatonin secretion and circadian regulation. The full mechanism of action is not fully elucidated, and the 'peptide bioregulator' theory of organ-specific gene regulation upon which much of this work is based has not been widely adopted in mainstream Western gerontology.

Evidence base

Evidence is limited and primarily from a single Russian research group (Khavinson and colleagues). Animal studies report telomere lengthening and lifespan extension (12–22% in flies and mice). Small human studies report improvements in ageing biomarkers. No independent replication or large-scale RCTs exist. Claims should be treated as preliminary and unconfirmed.

Protocols

Limited literature describes 5–10 mg/day subcutaneously for 10–20 day courses. No standardised protocol exists.

Not a controlled substance in the UK. Not MHRA-licensed as a medicine. Legal to purchase and possess for research purposes.
