Epitalon

Epitalon is a synthetic tetrapeptide based on the naturally occurring peptide epithalamin, which is extracted from the pineal gland. Developed by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology, epitalon is the most extensively studied of the Khavinson peptide bioregulators. Its primary mechanism of action involves activation of telomerase, the enzyme responsible for maintaining telomere length at chromosome ends. Telomeres shorten with each cell division, and this progressive shortening is considered a key hallmark of cellular aging. When telomeres become critically short, cells enter senescence or undergo apoptosis. Khavinson and colleagues demonstrated that epitalon can activate telomerase in human somatic cells, leading to elongation of telomeres and extension of cellular lifespan beyond the Hayflick limit. This was shown in human fetal fibroblast cultures where epitalon-treated cells underwent significantly more population doublings than controls. Epitalon also influences melatonin production. As a pineal bioregulator, it has been shown to restore the nocturnal melatonin peak in aged primates, which normally declines with age. This melatonin-related activity provides a secondary mechanism through which epitalon may affect aging processes, given melatonin's roles as an antioxidant and circadian regulator.

Animal studies have used doses of 0.1-1 mcg per animal in rodents. In primate studies, epithalamin was administered at doses equivalent to 10-20 mg of the natural extract. In vitro telomerase activation studies used micromolar concentrations.

Store lyophilized (freeze-dried) powder at -20°C to 4°C in a dry environment protected from light. Unreconstituted peptide is stable for extended periods when stored properly.

Once reconstituted with bacteriostatic water or an appropriate solvent, store at 2-8°C and use within the timeframe specified on the Certificate of Analysis. Avoid repeated freeze-thaw cycles.

A Certificate of Analysis documenting purity, identity, and recommended storage conditions is included with every order.
