— Product Overview
Description
Epithalon is also written Epitalon or Epithalone, and is often referred to by its one-letter sequence, AEDG. It was designed from the amino-acid composition of epithalamin, a bovine pineal gland extract; Epithalon itself is one defined synthetic sequence, not an extract.
Chemically it is a very small, acidic peptide. Glutamate and aspartate both carry acidic side chains; with the free C-terminal carboxyl and the single N-terminal amine, the net charge is about −2 at neutral pH. PubChem computes an XLogP3 of −5.5, which marks it as strongly hydrophilic. It has no tryptophan or tyrosine, so it cannot be quantified by UV absorbance at 280 nm, and no sulfur-containing residues (cysteine or methionine).
In an Epithalon 10mg vial, the labeled 10 mg is about 25.6 µmol, calculated from its molar mass. For laboratory research use only; not for use in humans or animals.

Frequently Asked Questions
What is Epithalon?
Epithalon (also spelled Epitalon) is the synthetic tetrapeptide Ala-Glu-Asp-Gly (AEDG).
What is it used for?
It is sold for in-vitro laboratory research only. It is not for use in humans or animals and is not intended to diagnose, treat, cure or prevent any disease.
Is Epithalon the same as Epitalon?
Yes. Epithalon and Epitalon are two transliterations of the same compound.
Is Epithalon the same as epithalamin?
No. Some chemical databases list the names as synonyms, but epithalamin is an extract of the bovine pineal gland, while Epithalon is a single synthetic tetrapeptide, Ala-Glu-Asp-Gly.
How is it supplied?
As a lyophilized (freeze-dried) powder in a sealed vial. Bacteriostatic water is sold separately.
How should it be stored?
Store the sealed vial at 2–8 °C, or at −20 °C for long-term storage. Keep reconstituted solutions refrigerated.
Is this product for human use?
No. It is sold strictly for laboratory research use only and is not for human or veterinary use.
Where is the COA for Epithalon?
Published lab reports are listed on the COAs page; the report for this product is added there when it is published.
When will my order ship?
Orders placed by 3 PM ET, Monday to Saturday, ship the same business day with tracking. Options and prices are on the Shipping Policy page.
