Epithalon

Epithalon (also spelled Epitalon) is a synthetic four-amino-acid peptide, Ala-Glu-Asp-Gly (AEDG), modeled on a natural pineal gland extract. It came out of decades of Russian gerontology research led by Vladimir Khavinson and is marketed as an anti-aging compound that supposedly switches telomerase back on. It has no approval from the FDA, EMA, or other Western regulators, and the human evidence is thin. The headline claim is telomerase activation, allowing telomeres to lengthen. It is also proposed to influence melatonin production, antioxidant defenses, and gene expression in the pineal-hypothalamic axis.
