Epithalon: the telomerase tetrapeptide
Epithalon (also written epitalon) is a short peptide widely referenced in longevity and cellular-aging research. This primer describes what it is and how it is handled, with no therapeutic or dosing claims.
What it is
Epithalon is a synthetic tetrapeptide — four amino acids (Ala-Glu-Asp-Gly). It is often described in the literature in relation to telomere and telomerase research. It is produced synthetically and supplied lyophilised.
Why it is studied
Epithalon is used as a tool compound in preclinical and in-vitro aging-related models. The conclusions belong to those studies; nothing here is a statement about human effects.
Handling notes
- Supplied lyophilised; reconstitute gently.
- Store the dry solid sealed, cold and dark.
- Refrigerate after reconstitution and aliquot for repeated use.
For in-vitro research use only. Not for human or veterinary use.
