Epitalon 50mg
Tetrapeptide Ala-Glu-Asp-Gly — Khavinson's pineal bioregulator. Researched for telomerase activation, telomere elongation, and circadian rhythm restoration in aged tissue models.
Telomerase Activation & Pineal Bioregulation
Epithalon (Epitalon, tetrapeptide Ala-Glu-Asp-Gly, CAS: 307297-39-8) is a synthetic version of the natural peptide Epithalamin isolated from bovine pineal gland extracts by Vladimir Khavinson. Its primary researched mechanism involves activation of telomerase (hTERT) — the enzyme that extends telomere length. Telomerase is active in germline and stem cells but silenced in most somatic cells; Epithalon appears to reactivate hTERT expression in fibroblasts and lymphocytes in vitro, with studies showing 24–33% telomere elongation at nanomolar concentrations. The proposed mechanism involves histone H3/H4 acetylation at the hTERT promoter — epigenetic chromatin remodeling rather than direct enzyme activation. Epithalon also regulates melatonin synthesis in the pineal gland and shows antioxidant properties. Molecular weight: 482.46 Da.
Research Highlights
Telomerase Activation Research
Khavinson et al. published in vitro studies showing Epithalon at nanomolar concentrations activates hTERT expression in human fetal fibroblasts, producing measurable telomere elongation (24–33%). The proposed mechanism involves epigenetic chromatin remodeling — histone H3/H4 acetylation at the hTERT promoter.
Pineal Gland & Melatonin Regulation
Animal studies show Epithalon normalizes the age-related decline in pineal melatonin synthesis. In aged rodents, the compound restored nightly melatonin surges to levels observed in young adults, with associated improvements in sleep architecture and circadian rhythm markers.
Longevity Protocol Context
In comprehensive longevity research stacks, Epithalon addresses the cellular aging component — telomere shortening is correlated with skin cell replicative senescence, hair follicle decline, and systemic inflammation. Foundational research comes from Khavinson's laboratory across 40+ published studies.
