What Is Selank? Anxiolytic Peptide Research Guide
An overview of Selank — a synthetic tuftsin-analogue peptide — covering how it is studied in anxiety and cognition research, and its research-use-only status in the UK.

What Is Selank?
Selank is a synthetic heptapeptide derived from the immunopeptide tuftsin. Like Semax it was developed in Russia, where related formulations have clinical history; elsewhere it is studied as a research compound.
Research use only. This material is supplied for in-vitro laboratory research. It is not a medicine and is not for human or veterinary consumption, administration, or therapeutic use.
How Selank Is Studied to Work
In research Selank is associated with anxiolytic-like effects and with modulation of GABAergic signalling, BDNF, and components of the immune system in laboratory models. It is also examined for possible influences on the balance of certain neurotransmitters.
Evidence & Regulatory Status
As with Semax, most Selank data comes from Russian research, with limited independent Western clinical validation. Selank is not licensed by the MHRA and is supplied for laboratory research only.
Research Handling & Quality
As a lyophilised (freeze-dried) peptide it is typically stored frozen and reconstituted with bacteriostatic water for in-vitro work — see our reconstitution guide and storage guide. Identity and purity should be verified against a batch-matched Certificate of Analysis (COA) with HPLC and mass-spectrometry data. View selank product details and COA.
