# Epitalon / Epithalon / AEDG

Epitalon is a defined synthetic tetrapeptide commonly written AEDG, or Ala-Glu-Asp-Gly. It is often confused with Epithalamin, a pineal-gland peptide complex from older Russian clinical-preparation literature, and with Endoluten, a Cytomax natural-complex pineal product-family name.

## Evidence map

Epitalon searches cluster around telomerase, melatonin, pineal function, anti-aging claims, and longevity protocols. This page treats those as research questions, not as proven human anti-aging benefits.

A 2025 Biogerontology cell-line paper reported telomere-length changes in normal human cells and breast-cancer cell lines through telomerase-related or ALT-related mechanisms. That makes telomerase claims safety-sensitive research context, not proof that Epitalon is a validated anti-aging intervention.

## Benefits and study-only dosage

- 2020 Molecules in-vitro AEDG paper: human gingival mesenchymal stem cells treated with AEDG at 0.01 ug/mL for one week; this is cell-culture exposure, not human dosage.
- 2014 Khavinson short-peptide table: identifies Epithalon/AEDG as Ala-Glu-Asp-Gly and places it in a neuroendocrine activity category; this is identity taxonomy, not benefit proof.
- Epithalamin cohort literature: pineal extract context, not synthetic AEDG dosage.

## Side effects

Side-effect information cannot be generalized from a sequence name alone. Route, purity, sterility, salt form, storage, excipients, concentration, and labeling all matter.

## FDA and legal status

This site does not identify an FDA-approved Epitalon drug in the United States. FDA approval, compounding, research-use labeling, Russian clinical history, and supplement catalog listings are separate issues.
