Alternate names: Tuftsin analogue, TP-7
Historical context
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.

Catalogue line
One fill: [Selank 10mg](/product/selank-10mg), at the same AED price as [Semax 10mg](/product/semax-10mg). [Selank + Semax 10mg](/product/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](/articles/semax-vs-selank-research).

Receiving
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.
