Epitalon is the tetrapeptide Ala-Glu-Asp-Gly, abbreviated AEDG. Identity, sequence confirmation, chromatographic purity and quantitative peptide content are related but separate measurements.
Evidence at a glance
- PubChem lists sequence AEDG, formula C14H22N4O9 and molecular weight 390.35 g/mol.
- Epitalon, Epithalon and Epithalone appear as synonyms, but Epithalamin refers to a different historical extract context and should not be collapsed automatically.
- A purity percentage does not report water, residual solvents, counterions or absolute peptide content.
Identity record
The four-residue order and stereochemistry define the reference compound. A certificate should state the molecular form used for mass calculations and whether the reported amount is on an as-is, anhydrous or peptide-content basis.
Analytical and evidence boundary
Mass spectrometry supports molecular identity while chromatography estimates separation of major components. Neither test alone establishes biological activity, sterility, endotoxin, stability or suitability for a particular experimental system.
Product copy should use “studied in cell-aging and mouse-oocyte models.” It should not use “extends lifespan,” “reverses aging” or similar language without direct controlled human outcome evidence.
Editorial rule
State the exact material, form, model or population and endpoint supported by the cited record. Do not convert mechanistic plausibility, an animal result, an official finished-drug label or an analytical test into a claim about an unrelated catalog lot.
