Epitalon: what the studies show

Epitalon and epithalamin

Epitalon, also spelled Epithalon, is the synthetic tetrapeptide Ala-Glu-Asp-Gly, or AEDG. Epithalamin is an animal pineal extract containing multiple peptides. Survival findings from that extract cannot be assigned to Epitalon.

Cell and human biomarker studies

A 2003 experiment added Epithalon to human fetal fibroblast cultures and reported telomerase activity and longer telomeres. No participants received treatment in that experiment.

A separate human study examined sublingual AEDG in middle-aged women working night shifts. FDA's review describes 20 women receiving AEDG and 20 receiving placebo among those with reduced melatonin output. Treatment lasted 20 days. Researchers reported changes in urinary melatonin-metabolite excretion and clock-gene expression. They did not measure sleep improvement or lifespan, and blinding was unspecified.

No established longevity schedule

The sublingual study does not validate injections or repeated longevity courses. No FDA-approved product was identified. The sublingual findings do not establish efficacy for marketed injections. The unresolved question is whether reproducible biomarker changes lead to meaningful health benefits with acceptable long-term safety.
