Selank // The Neuropeptide Dossier: The Stabilised Tuftsin
Why a modified immune peptide became a neuropeptide research tool.
EuroVials Research Desk // Editorial · Cognitive & Neuro
Selank is a synthetic peptide based on the immune peptide tuftsin, modified for stability by researchers at the Institute of Molecular Genetics. That modification is what turned a short-lived native peptide into a usable research tool.
The Peptide That Was Built to Last
Native tuftsin degrades quickly. Selank extends it with a stabilising tail, and that single design choice is why it exists as a research compound at all — it survives long enough to study.
“Stability first — the rest of the research follows from it.”
What Makes Selank Notable?
A heptapeptide extending the native tuftsin sequence with an additional tripeptide tail, which the literature credits for improved resistance to enzymatic breakdown versus unmodified tuftsin.

The EuroVials Standard
Every Selank batch is validated before it leaves the lab. The Certificate of Analysis (COA) is the binding source of truth for each batch — generated by Janoshik, an independent third-party laboratory, prior to dispatch. We publish no claim that the COA doesn't support.
- 01RP-HPLC with UV detection — purity 99%+
- 02Mass spectrometry — molecular-mass confirmation
- 03Independent third-party verification (Janoshik) — COA available on our certificates page
For the full analytical dossier of your specific batch, consult the COA included with your shipment or on our certificates page. For in-vitro laboratory research only. Not for human or animal consumption.
Conclusion
Selank is a stabilised-tuftsin reference for anxiolytic and neuropeptide research, the natural counterpart to Semax. EuroVials supplies it sequence-confirmed with a COA on file.
