Description
A synthetic four-amino-acid peptide related to a natural pineal gland compound, studied for its influence on telomerase activity and circadian/endocrine regulation in longevity-focused research.
Epithalon is a four-residue peptide - alanine, glutamic acid, aspartic acid, glycine - with no terminal modifications at all. Its small size and simple structure make it one of the most stable and most easily verified items in the catalogue.

Every lot ships against its own certificate of analysis. Search by lot number on the certificates of analysis page, or check the paperwork before you order.
Epithalon is supplied for laboratory research use only. It is not a drug, food or cosmetic, and it is not for human or veterinary use.
| Reconstitution | Readily soluble in water. |
|---|---|
| Storage, lyophilised | -20 °C, sealed and desiccated, protected from light. |
| Storage, reconstituted | 2-8 °C, protected from light. Short unmodified peptides like this one are comparatively stable in solution; use within 2-4 weeks. |
| Shipping | Shipped at ambient temperature. Lyophilised material tolerates transit without a cold chain; move it to the freezer on arrival. |
Working notes
- Let a vial come to room temperature before opening it. Opening a cold vial draws in moist air, and lyophilised powder takes up water quickly.
- Add the diluent slowly down the inside wall of the vial rather than directly onto the powder cake, and let it dissolve on its own. Shaking a peptide solution is the fastest way to denature it.
- Wipe the stopper with alcohol before every draw, and keep solutions out of direct light.
- Repeated freeze-thaw cycles cost you more purity than time in the fridge does. If a vial will be used over weeks, aliquot it once and freeze the aliquots.
