Epitalon (also Epithalon) is a synthetic tetrapeptide, Ala-Glu-Asp-Gly (AEDG), modeled on the pineal peptide Epithalamin. It is studied as a regulator of telomerase (hTERT) activity, telomere length, and pineal/circadian signaling. This product is supplied as a lyophilized research-grade peptide for in vitro and preclinical laboratory investigation only.

Investigational directions enabled by the published mechanism — not therapeutic claims.
- ◆hTERT / telomerase activation and dose-dependent telomere elongation in normal cell lines
- ◆ALT (alternative lengthening of telomeres) studies in cancer cell lines
- ◆Epigenetic AEDG–DNA interaction and neurogenesis-related gene expression
- ◆AANAT / pCREB pineal signaling and circadian / melatonin research
In published models, Epitalon upregulates hTERT mRNA, activating telomerase and extending telomeres in normal, telomerase-competent cells, while engaging the ALT pathway in certain cancer lines — two mechanistically distinct routes to telomere lengthening. AEDG–DNA interaction has been linked to gene-expression changes during neurogenesis, and AANAT/pCREB modulation to pinealocyte melatonin regulation.
