Selank
Cognitive Research
Available sizes: 5 mg, 10 mg
A stabilised tuftsin analogue
Selank is Thr-Lys-Pro-Arg-Pro-Gly-Pro — the tuftsin sequence with a Pro-Gly-Pro extension. Tuftsin itself is a fragment of the IgG heavy chain with immunomodulatory activity; the extension serves the same purpose as in Semax, protecting the peptide from rapid degradation.
The immunological ancestry is not incidental. Part of the Selank literature concerns immune signalling rather than anxiety, and interleukin-6 expression is a recurring measured endpoint.
Research areas
Anxiety models in rodents, the primary research focus
GABAergic signalling, the most frequently proposed mechanism
Enkephalin degradation, which Selank is reported to inhibit — a route to endogenous opioid signalling without an opioid
Interleukin-6 and immune gene expression, inherited from tuftsin
BDNF expression, the shared thread with Semax
Documentation and verification
Certificates of Analysis are published for tested products and batches. A certificate is a batch-specific record: it reports what was measured, by which method, on a stated date, against a batch identifier. It is evidence about the sample analysed at the time of analysis, and it is silent on attributes it does not list and on what has happened to the material since.
The batch number is the field that connects the document to a physical vial. Where the identifier on a vial does not appear on a certificate, the certificate does not describe that vial, however thorough the analysis behind it was. Batch records can be searched directly, and the guides below explain what each field establishes and what it does not.

- Storage and handlingWhat defined storage conditions mean, and why cold slows degradation.
