Short-peptide research
Vesugen
Vesugen is the tripeptide Lys-Glu-Asp, also written KED and sometimes T-38 in Khavinson-group literature. VaultLabs supplies a 10 mg lyophilized vial. It is not Epithalon (Ala-Glu-Asp-Gly) and not Pinealon (Glu-Asp-Arg), even though the masses sit close together. It is not an approved medicine.

What Vesugen is
Vesugen, Epithalon and Pinealon are three short peptides from a related literature family and three different sequences. Vesugen is Lys-Glu-Asp, CAS 204271-66-9, 390.39 g/mol. Epithalon is one residue longer. A mass that looks similar on a quick glance is not an identity match. The lot record has to name KED.

How VaultLabs catalogues it
One fill: Vesugen 10mg. Epithalon 10mg and Pinealon are separate SKUs with separate monographs. The Vesugen monograph is /compounds/vesugen.
Put the sequence on the inventory row, not only the trade name. A 10 mg fill is shared by several short peptides in this catalogue, so the fill alone does not identify the vial.
Lots and receiving
Each sealed unit carries its own lot number. The current catalogue certificate for that lot is published on the batch page and states purity of at least 99.8 percent on the same VaultLabs template used for the rest of the lyophilized catalogue. A certificate for one fill does not qualify another fill. A certificate for a blend does not qualify a single-sequence vial that happens to share part of a name. Do not copy a purity figure from a different product, from a photograph of another vial, or from a paper into the receiving file. Match the printed name, the nominal mass and the lot number on the vial to the published record. If those three do not agree, hold the unit and ask for the document that belongs to that unit before it leaves quarantine. Enter the printed lot at batch verification.
Storage and research-use boundary
Keep the sealed lyophilized vial at 2 to 8 degrees Celsius, protected from light and from moisture, until it is opened under the laboratory's own procedure. Allow the closed vial to reach room temperature before the seal is broken, so water from humid coastal air does not condense on the dry cake. Bacteriostatic water and sterile water are separate catalogue lines. They are not packed inside the peptide box, because the receiving laboratory chooses the medium in its own procedure. VaultLabs does not publish a preparation method on this page. After the seal is opened, solution age, container and freeze cycles are controlled by the laboratory, not by the catalogue page.
The material is supplied for in vitro laboratory research only. It is not for human or animal consumption. It is not an approved medicine, not a finished cosmetic, and not a personal-use item. Papers cited on the compound monograph describe other people's experiments. Those papers are not a description of what this vial will do, and they are not instructions for any person or animal. A buyer who needs a registered medicine should use a licensed pharmacy channel. This page exists so a procurement officer in the UAE can identify the catalogue line, the fill, the price band and the paperwork before raising an order.
