Epitalon
  Epitalon (epitalon, or epithalamin in synthetic form) is a tetrapeptide consisting of the amino acids Alanine–Glutamic acid–Aspartic acid–Glycine (Ala-Glu-Asp-Gly). It was developed on the basis of a natural peptide.
Epitalon regulates the functions of the pineal gland and affects the synthesis of melatonin, biorhythms, immunity and cellular renewal processes. One of the most studied effects is the activation of telomerase, an enzyme that extends the length of telomeres, which is associated with slowing down the aging process at the cellular level.
Due to its wide range of bioregulatory effects, Epitalon is used in anti-aging therapy and is also being studied as a potential drug for prolonging life and preventing age-related diseases.
