What does Epitalon do? Benefits and evidence

A peptide with telomerase effects in cells, but no proof that people live longer.

Also called: Epithalon, Epithalone, AEDG, Ala-Glu-Asp-Gly.

Khavinson bioregulator peptides · Synthetic pineal tetrapeptide studied in telomere and circadian models.

Epitalon is a four-amino-acid peptide studied for aging, sleep rhythms and retinal disease. Small human studies mainly come from one research network; longer life remains unproven. Cell telomere changes do not prove a human benefit. Epithalamin is a different pineal extract. Long-term cancer risk and injection safety remain unknown.

  • In a tiny study, it changed levels of melatonin, the body's sleep hormone, but did not show better sleep or longer life. (Studied in a trial)
  • An older study of eye injections in people with retinitis pigmentosa suggested changes in vision, without modern trial safeguards. (Studied in a trial)
  • Its anti-aging claims about telomeres come from lab studies on cells, which cannot show longer life in people. (animal)
  • People report taking it for aging; one user reported better sleep, while others felt no effect. (Reported by users)

Uses in the sources

  • Small human studies measured melatonin or clock genes; they did not establish a reliable insomnia benefit. (Studied in a trial) (source)
  • An older controlled report studied local eye injections for retinitis pigmentosa. (Studied in a trial) (source)
  • Users take it for aging goals. Human lifespan extension has not been shown for synthetic Epitalon. (Reported by users) (source)
