Epitalon (Epithalamin Tetrapeptide)
Also Known AsEpithalon · Epithalone · Epithalamin · AGAG
Developed by Vladimir Khavinson at the Saint Petersburg Institute of Bioregulation and Gerontology as a synthetic tetrapeptide analog of epithalamin, a polypeptide extract from the pineal gland. Khavinson's bioregulatory peptide program has produced multiple short peptides designed to restore organ-specific function in aging.
Ala-Glu-Asp-GlyHow Epitalon Works
Telomerase Activation
Epitalon activates telomerase reverse transcriptase (hTERT) gene expression, enabling telomere elongation in somatic cells. In human fetal fibroblast and retinal pigment epithelium cell cultures, epitalon treatment increased telomere length and extended replicative lifespan beyond the Hayflick limit.
Pineal Gland & Melatonin Regulation
Restores melatonin synthesis and circadian melatonin secretion patterns in aging organisms. The mechanism involves normalization of pinealocyte function and reversal of age-related calcification effects, restoring the amplitude and timing of the endogenous melatonin rhythm.
Antioxidant Defense Restoration
Normalizes activity of key antioxidant enzymes (SOD, catalase, glutathione peroxidase) that decline with age. This restoration is secondary to melatonin normalization and direct gene regulatory effects on antioxidant response elements.
Published Research
Telomere Biology & Cellular Aging
ModerateIn vitro studies demonstrate that epitalon activates telomerase in human somatic cells, extending replicative capacity by 44% in fibroblasts (from passage 34 to passage 49). Telomere length measurements confirm actual elongation rather than just delayed shortening. This represents one of the few pharmacological approaches to telomerase induction in normal (non-cancer) somatic cells.
Lifespan Extension
ModerateMultiple preclinical studies in mice, rats, Drosophila, and C. elegans demonstrate lifespan extension of 13-31% with epitalon/epithalamin treatment. The most cited study showed a 31% increase in mean lifespan in CBA mice. Effects are attributed to combined telomere maintenance, melatonin restoration, and antioxidant normalization.
Circadian Rhythm & Sleep
ModeratePreclinical and clinical studies in elderly subjects demonstrate restoration of normal melatonin secretion patterns. Evening melatonin peak amplitude increases significantly, and the timing of circadian melatonin onset normalizes toward youthful patterns. Published clinical observation studies report improved sleep quality.
Retinal Degeneration
PreclinicalPreclinical studies in Campbell rat models of retinitis pigmentosa show preserved retinal morphology, maintained electroretinogram responses, and delayed photoreceptor degeneration with epitalon treatment. Effects attributed to telomerase activation in retinal pigment epithelium and antioxidant defense restoration.
Safety Profile
Epithalamin/epitalon has been studied in Russian clinical settings for over 20 years with reported favorable safety. As a tetrapeptide (4 amino acids), it is rapidly metabolized with minimal systemic accumulation. Published studies report no adverse effects in human subjects. Theoretical concern regarding telomerase activation in pre-cancerous cells exists but has not been observed in published literature.
Handling & Storage
Reconstitute with bacteriostatic water. Epitalon is a small, highly soluble tetrapeptide. Store reconstituted solution at 2-8°C. Lyophilized powder stable at -20°C for 24+ months. Protect from repeated freeze-thaw cycles.

Epitalon FAQ
What is Epitalon?
Epitalon (also spelled Epithalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed by Vladimir Khavinson as a synthetic analog of epithalamin, a pineal gland extract. It is one of the few compounds shown to activate telomerase in human somatic cells, and it has demonstrated lifespan extension in multiple animal models.
Does Epitalon actually lengthen telomeres?
Yes. Published research in Bulletin of Experimental Biology and Medicine (2003) demonstrated that Epitalon activates telomerase and elongates telomeres in human fetal fibroblasts and retinal pigment epithelium cells. Treated cells exceeded the Hayflick limit by 44%, directly demonstrating functional telomere elongation.
How does Epitalon affect melatonin?
Epitalon restores age-related decline in melatonin synthesis by normalizing pineal gland function. Studies in elderly subjects show increased evening melatonin peak amplitude and restoration of circadian secretion patterns toward youthful levels. This is attributed to direct bioregulatory effects on pinealocyte gene expression.
Could telomerase activation cause cancer?
This is a legitimate theoretical concern that has been addressed in published literature. Multiple long-term animal studies with epitalon/epithalamin show either no change or decreased spontaneous tumor incidence, despite telomerase activation. The mechanism may involve selective activation in normal cells combined with improved immune surveillance via melatonin restoration. However, this remains an active area of investigation.
