Selank

Selank and Semax are both seven-residue peptides with a C-terminal Pro-Gly-Pro, which is why purchase orders keep pairing them. The first four residues are not the same. Selank is Thr-Lys-Pro-Arg-Pro-Gly-Pro, CAS 129954-34-3, 751.9 g/mol. Semax is Met-Glu-His-Phe-Pro-Gly-Pro, CAS 80714-61-0, 813.87 g/mol. A shared three-residue tail is not an identity match. The lot record has to name the sequence that is in the vial.

Selank is the synthetic heptapeptide Thr-Lys-Pro-Arg-Pro-Gly-Pro, a tuftsin-related sequence that ends in Pro-Gly-Pro. VaultLabs supplies it as a 10 mg lyophilized vial at the same AED price as Semax 10 mg. It is not Semax (Met-Glu-His-Phe-Pro-Gly-Pro, CAS 80714-61-0) and it is not the Selank + Semax blend. CAS 129954-34-3. Formula C33H57N11O9. Molecular weight 751.9 g/mol. It is not an approved medicine.

One fill: Selank 10mg, at the same AED price as Semax 10mg. Selank + Semax 10mg is a dual-peptide lot with no single CAS. Do not substitute one of these three for another. The side-by-side identity note is Semax versus Selank.

Write Selank, 10 mg, and the lot. A certificate for Semax does not release this vial. A certificate for the blend does not release this vial. A photograph of a label is not a laboratory report.

Each sealed unit carries its own lot number. The certificate for that lot is the purity record, and it is published on the batch page when the laboratory report for that unit is on file. Until that report is published, the purity figure is not copied from a catalogue average, from a label photograph, or from a paper. A certificate for Semax does not qualify this vial. A certificate for the Selank + Semax blend does not qualify this single-sequence vial. Match the printed name, the nominal mass and the lot number on the vial to the published record. If those three do not agree, or if no record is published yet, hold the unit and ask for the document that belongs to that unit before it leaves quarantine. Enter the printed lot at batch verification.

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.
