Epithalon Research Guide 2026: Tetrapeptide Background, Chemistry, COA & Handling

Epithalon research centers on a synthetic tetrapeptide, Ala-Glu-Asp-Gly (AEDG), that appears in the Khavinson bioregulator literature on pineal peptides and telomerase-related pathways. This guide covers the background, the chemistry researchers should verify, and handling practices that protect sample integrity. For Research Use Only. Not for human consumption.

What Epithalon Is in the Research Literature

Epithalon, also written epitalon, is a four-amino-acid peptide studied in laboratory and preclinical settings. Published work from the Khavinson research group describes it in the context of pineal gland peptide research and cell-culture telomerase activity. Much of that literature is preclinical, and results vary by model and protocol. Nothing in this guide describes a human use, dose, or outcome.

Chemistry Researchers Should Verify

Because epithalon is a short sequence, purity and identity matter more than the sequence name alone. Before any experiment, confirm the following on the supplier's documentation:

Sequence confirmation by mass spectrometry, so the molecular weight matches the expected AEDG structure. Purity by HPLC, with the chromatogram and percentage reported for the specific lot. Counter-ion and salt form, since these change the net mass and the amount you weigh out. Residual solvent and endotoxin data, if your study depends on low-background conditions.

A certificate of analysis tied to a batch number is the baseline. A generic COA that is not lot-specific does not confirm the material you received.

Handling and Storage Practice

Lyophilized peptides are generally more stable than solutions. Keep the vial sealed, protected from light, and stored cold according to the supplier's instructions. Allow a sealed vial to reach room temperature before opening to limit condensation. Once reconstituted, record the solvent, date, and concentration, and avoid repeated freeze-thaw cycles by aliquoting. Label every aliquot with the compound name, lot number, and preparation date so the sample history stays traceable.

Designing a Clean Research Record

A reproducible study starts with a documented chain of custody. Log the lot number, the COA reference, storage conditions, and each handling step. Use matched vehicle controls and blinded analysis where your protocol allows. If results conflict with published reports, check the purity data and handling records first, since degraded or mislabeled material is a common source of discrepancy.

Frequently Asked Questions

Is epithalon approved for human use?

No. Epithalon is sold here strictly for laboratory research. It is not approved as a drug or dietary product for people, and nothing in this guide should be read as a medical claim.

What does AEDG stand for?

AEDG is the one-letter sequence of the four amino acids in epithalon: alanine, glutamic acid, aspartic acid, and glycine.

Which document should I check first when a lot arrives?

Start with the lot-specific certificate of analysis. Confirm the batch number matches the vial, then review the mass spectrometry and HPLC results.

How should epithalon be stored after reconstitution?

Store solutions cold, protect them from light, and aliquot to avoid repeated freeze-thaw cycles. Follow the stability guidance supplied with the lot, and record how long each aliquot has been held.

Where can I find the research-use product information?

Check the product listing for research-use terms and any documentation provided for the specific lot before any purchase or study design.

Next Steps for Your Lab

If you are planning a study that involves epithalon, review the lot documentation first, then build your storage and logging plan before the vial is opened. Browse the Precision Labs research catalog for current listings and documentation. For research use only, not for human consumption.
