Epithalon
Pineal tetrapeptide AEDG

A synthetic tetrapeptide (Ala-Glu-Asp-Gly) studied for reported effects on telomerase expression and telomere length in cultured cells.
Epithalon is the synthetic AEDG tetrapeptide. It should not be confused with "epithalamin", a pineal gland extract used in much of the older Russian literature — the two are routinely conflated, and the extract studies are not epithalon studies.
Evidence is in vitro and rodent only, and originates predominantly from a single research group. Supplied lyophilised. Not an approved medicine.

Full research profilePreclinical evidence only
Epithalon peptide induces telomerase activity and telomere elongation in human somatic cells
Reported telomerase induction and telomere elongation in cultured human fetal fibroblasts.
Effect of Epitalon on biomarkers of aging, life span and spontaneous tumor incidence in female Swiss-derived SHR mice
Reported effects on ageing biomarkers and lifespan in mice; one of the few studies using the synthetic tetrapeptide rather than pineal extract.
Epitalon increases telomere length in human cell lines through telomerase upregulation or ALT activity
Independent replication attempt reporting telomere lengthening across human cell lines via two distinct mechanisms.
