Epithalon (Epitalon)

CPreclinical

Synthetic tetrapeptide · 4 amino acids

Not FDA ApprovedWADA Banned

Epithalon is a synthetic tetrapeptide based on the natural peptide epithalamin, produced by the pineal gland. Research by Vladimir Khavinson suggests it may activate telomerase and extend cellular lifespan.

Mechanism of Action

Proposed to activate telomerase, the enzyme that adds telomeric repeats to chromosome ends. May stimulate pineal gland melatonin production and modulate circadian rhythms.

Benefits

  • Telomerase activation observed in human cell cultures
  • Elongated telomeres in cell studies
  • Restored melatonin cycling in aged primates
  • Extended lifespan in some animal models
