Epitalon contains only four amino acids—but a short sequence does not make analytical identity optional.
Search online and the same research peptide may appear under several names:
Epitalon. Epithalon. Epithalone. AEDG. Ala-Glu-Asp-Gly.
For a professional research buyer, the important question is not which spelling appears on the label.
It is:
Does the batch documentation prove that the material corresponds to the intended AEDG peptide?
What Is Epitalon?
Epitalon, also commonly written Epithalon, is a synthetic tetrapeptide composed of:
Ala-Glu-Asp-Gly
or in one-letter notation:
AEDG
Common identifiers include:
CAS: 307297-39-8
Molecular Formula: C14H22N4O9
Molecular Weight: approximately 390.35 g/mol
Sequence: H-Ala-Glu-Asp-Gly-OH
The peptide has been investigated in experimental research involving cellular signaling, telomerase biology, neuroendocrine mechanisms and aging-related pathways.
However, research interest does not eliminate the need for analytical verification.
Epitalon and Epithalon: Is There a Difference?
In scientific and chemical databases, Epitalon and Epithalon are commonly treated as synonyms for the AEDG tetrapeptide.
That does not mean a product label containing either name automatically establishes identity.
A professional buyer should connect:
Name → AEDG sequence → CAS → molecular mass → chemical form → analytical data
The name is only the beginning of the specification.
Four Amino Acids Still Require Identity Testing
Epitalon is structurally much smaller than many research peptides.
But HPLC purity and molecular identity remain separate questions.
A chromatogram showing ≥99% purity can demonstrate that a principal chromatographic component dominates the sample.
It does not independently prove that the principal peak is:
Ala-Glu-Asp-Gly.
That is why appropriate identity or mass analysis can add important information.
Free Base or Acetate? Chemical Form Matters
Another detail is becoming increasingly important in Epitalon sourcing: chemical form.
Regulatory discussions distinguish Epitalon-related substances such as Epitalon free base and Epitalon acetate.
For analytical work, those terms should not be treated as meaningless wording differences.
Counterion or chemical-form information may influence:
- molecular-mass interpretation;
- assay calculations;
- impurity profiles;
- specification matching;
- comparability between batches.
Professional buyers should therefore confirm the exact form against the applicable batch-specific COA.
Why “99% Pure” Is Not the Complete Question
When sourcing Epitalon, a useful analytical chain is:
AEDG Sequence → Chemical Form → Molecular Identity → HPLC Purity → MS/LC-MS → Batch COA
This avoids a common procurement mistake:
assuming purity automatically proves identity.
It does not.
What Does the Research Actually Show?
Epitalon has been studied in cell, animal and mechanistic models involving telomerase activity, cellular aging pathways, melatonin-related biology and other signaling systems.
These research findings are scientifically interesting.
But they should not be converted into claims that research-grade Epitalon has been proven to:
- reverse human aging;
- extend human lifespan;
- treat insomnia;
- restore telomeres clinically;
- prevent age-related disease.
Research evidence and commercial product claims are different things.
What Do Epitalon Reviews Say?
Online experiences are mixed.
Positive anecdotal comments sometimes describe perceived improvements in:
- sleep quality;
- circadian rhythm;
- energy;
- recovery.
Negative reports include:
- no noticeable effect;
- insomnia;
- disrupted sleep;
- fatigue;
- brain fog;
- unusual subjective reactions.
These accounts cannot establish safety, efficacy or material quality.
The actual peptide source, purity, chemical form, concurrent compounds and user health status are usually unknown.
What Should a B2B Buyer Verify?
When comparing an Epitalon supplier, professional laboratories may consider checking:
Sequence Identity
Does the documentation specify Ala-Glu-Asp-Gly / AEDG?
CAS and Molecular Specification
Does the material correspond to CAS 307297-39-8 and the intended molecular form?
Chemical Form
Is the material specified as the relevant free-base, acetate or other documented form?
HPLC Purity
Does the chromatogram belong to the actual production batch?
MS / LC-MS Identity
Where appropriate, does mass analysis support the intended molecule?
Impurity Information
Are peptide-related impurities appropriately characterized?
Lot Traceability
Do the vial, COA and analytical records correspond to the same production lot?

FAQ
Are Epitalon and Epithalon the same peptide?
They are commonly used as synonyms for the tetrapeptide Ala-Glu-Asp-Gly (AEDG).
What is the Epitalon sequence?
The sequence is Ala-Glu-Asp-Gly, abbreviated AEDG.
What is the CAS number of Epitalon?
Epitalon is commonly identified by CAS 307297-39-8.
Does ≥99% HPLC prove Epitalon identity?
No. HPLC purity and molecular identity are different analytical questions.
Why should chemical form be specified?
Free-base, acetate or other counterion forms can affect analytical interpretation and should correspond to the batch-specific specification.
Is Epitalon proven to reverse human aging?
No. Experimental research involving telomerase and aging-related biology should not be interpreted as proof that research-grade Epitalon reverses human aging or extends human lifespan.
