Epithalon

Overview

Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed by Khavinson as an analog of the bovine pineal extract Epithalamin. It is a research-only bioregulator — not FDA-approved — investigated for claimed telomerase activation and circadian/melatonin effects, with evidence limited primarily to Khavinson-group studies.

Mechanism of Action

Khavinson-group in vitro studies claim upregulation of telomerase activity / hTERT expression in cultured human somatic cells, with modulation of pineal melatonin secretion and circadian/age-related gene-expression markers. These mechanism claims have not been consistently replicated outside the originating research group.

Research Summary

The evidence base is dominated by Khavinson-group publications. A 2003 Bulletin of Experimental Biology and Medicine paper reported telomerase activation and telomere elongation in cultured human somatic cells. Open-label and small-cohort studies in elderly Russian patients have reported reduced mortality over 6–12 year follow-up and normalization of melatonin rhythms, but these trials have significant methodological limitations (open-label, single-center, limited controls) and have not been independently replicated in rigorous Western controlled trials. No Phase 2/3 trials, no FDA approval.

Dosing Information

Reported Side Effects

• Limited human safety data — generally described as well-tolerated in Khavinson-group studies
• Injection site discomfort
• Theoretical concern: telomerase upregulation could potentially support growth of occult malignancy

Labs to monitor before & during your Epithalon protocol

These biomarkers are commonly tracked to assess response and safety. Run baseline labs before starting, mid-cycle labs halfway through, and post-cycle labs 1–2 weeks after the final dose.
