Epitalon
Tetrapeptide studied for telomere elongation, circadian rhythm regulation, and aging research. Primarily from Russian research programs. Investigated as a pineal gland peptide bioregulator with telomerase-activating properties.
Epitalon (also Epithalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from epithalamin, a natural peptide extract from the pineal gland first studied by the St. Petersburg Institute of Bioregulation and Gerontology in Russia beginning in the 1980s. It is the most-studied peptide bioregulator from this research program.
The proposed primary mechanism involves activation of telomerase — the enzyme responsible for maintaining telomere length at the ends of chromosomes. Telomere shortening is associated with cellular aging and senescence; telomerase activation could theoretically slow this process. In vitro studies have demonstrated telomerase activation and telomere elongation in human cell cultures.
The evidence base is primarily from Russian research programs and does not conform to Western regulatory standards for clinical trial design and reporting. In physician practice, Joseph uses a 10-day on/20-day off cycle structure. This is a working practice framework, not an evidence-based standard.
