Epitalon (Ala-Glu-Asp-Gly): Research Overview and Identifiers
Quick Answer
Epitalon (also spelled Epithalon) is a synthetic tetrapeptide, Ala-Glu-Asp-Gly, designed after epithalamin, a peptide extract of the pineal gland. Its formula is C14H22N4O9, molecular weight 390.3 g/mol, CAS 307297-39-8. In the literature it appears mostly in telomerase and telomere-length studies in cultured cells, in gene-expression work and in pineal and melatonin-pathway research.
Key Takeaways
- Four residues: Ala-Glu-Asp-Gly.
- C14H22N4O9, 390.3 g/mol, CAS 307297-39-8.
- Studied in telomerase activity and telomere-length assays.
- Often grouped with NAD+ and MOTS-c in cellular-ageing research sets.

Where Epitalon Comes From
Epithalamin is a mixture of peptides extracted from the pineal gland. Researchers later identified a short sequence associated with its activity and synthesized it as a defined tetrapeptide. Because it is small and synthetic, Epitalon is fully characterized by its sequence, which makes identity checks on a certificate straightforward.
Research Areas
- Telomerase activity and telomere length in cultured cells
- Gene-expression studies
- Pineal gland and melatonin-pathway research
In cellular-ageing research it is often studied alongside NAD+ and MOTS-c; our Epitalon + NAD+ + MOTS-c research bundle supplies all three with separate lot numbers. For background on NAD+, see the NAD+ research overview.
Storage of the Sealed Vial
All of these compounds ship as lyophilized (freeze-dried) solids in sealed vials. Store sealed vials as stated on the label, protected from light and moisture, and see our storage and handling guide for temperature ranges. Each vial is labelled with its lot number, which ties it to its certificate.
Analytical Verification and Documentation
Each lot is tested by Testides, an independent laboratory, for HPLC purity and content. Certificates are published with their report numbers so they can be checked against the lab’s own record:
