A synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from the pineal gland extract epithalamin. Studied for over four decades for its ability to influence telomere length, regulate melatonin production, and support biological aging processes.
Epitalon is a synthetic tetrapeptide consisting of four amino acids: alanine, glutamic acid, aspartic acid, and glycine (Ala-Glu-Asp-Gly). It was developed by Dr. Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology, derived from epithalamin — a polypeptide extract of the bovine pineal gland. Khavinson's research on epitalon and related bioregulator peptides spans over 40 years.
The pineal gland is the body's master circadian regulator, producing melatonin in response to darkness. As we age, pineal function declines, melatonin output drops, and circadian regulation weakens. Epitalon is studied for its ability to restore pineal function — increasing melatonin production and resynchronizing circadian rhythms disrupted by aging.
Beyond melatonin, epitalon's most discussed property is telomere biology. Telomeres are protective caps on chromosomes that shorten with each cell division — a central mechanism of cellular aging. In vitro studies and animal data show epitalon activates telomerase, the enzyme that maintains or elongates telomeres. If this mechanism translates to in vivo human application, it represents a direct intervention in cellular aging.
Epitalon has been shown to activate telomerase in cell studies, leading to telomere elongation in human somatic cells — a potential mechanism for slowing cellular aging.
Stimulates the pineal gland to restore melatonin production that declines with age — supporting sleep architecture, circadian regulation, and the downstream antioxidant effects of adequate melatonin.
Reduces lipid peroxidation and oxidative stress markers in animal studies, contributing to an anti-aging cellular environment that protects DNA and mitochondria.
Khavinson's research shows epitalon and related bioregulators influence gene expression patterns associated with aging — reducing expression of senescence-associated genes.
Animal data shows epitalon supports immune function with aging, including T-cell activity and NK cell numbers — the immune components most affected by immunosenescence.
Epitalon has one of the longest research timelines of any peptide in the longevity space — Khavinson's program produced over 100 publications spanning cell biology, animal studies, and human observations.
Epitalon is administered subcutaneously or intramuscularly. Oral bioavailability is very low for peptides of this size, making injection the standard research route. The typical protocol runs in cycles of 10–20 days, repeated 1–2 times per year.
| Parameter | Detail |
|---|---|
| Standard Dose | 100 – 200 mcg per injection |
| Frequency | Daily |
| Cycle Length | 10 – 20 days per cycle |
| Cycles Per Year | 1–2 cycles (spring/fall timing common) |
| Route | Subcutaneous or intramuscular |
| Storage | Refrigerate lyophilized; use reconstituted within 30 days |
Studies in human somatic cells show epitalon activates telomerase expression, resulting in measured telomere elongation. While these are cell culture findings, they provide direct mechanistic evidence for the telomere biology claim.
Multiple Khavinson-led animal studies show increased mean and maximum lifespan in mice and rats treated with epitalon or epithalamin — effects attributed to reduced tumor incidence and enhanced antioxidant defense.
Human observations and animal data confirm epitalon and epithalamin restore melatonin secretion amplitude in aged subjects — the circadian/sleep regulatory mechanism most directly linked to pineal support.
Khavinson's program showed reduced spontaneous tumor incidence in rodents treated with epitalon — effects attributed to antioxidant protection and restoration of immune surveillance functions.
