In 62 patients with generalized anxiety disorder and neurasthenia, selank (30 patients) produced anxiolytic effects similar to medazepam (32 patients) on Hamilton, Zung and CGI scales.

premium-grade research peptides
Selank10 mg
Synthetic Tuftsin analog. Anxiolytic and nootropic premium-grade research peptide. Lyophilized powder for reconstitution.
What it is
Selank is a synthetic heptapeptide built from the immune tetrapeptide tuftsin extended with a stabilising Pro-Gly-Pro tail. It was developed in Russia, where it is registered as an anxiolytic, and it appears in anxiety, stress-response and neuroimmune research. Almost all of its clinical literature is Russian, with no Western randomised trial.

How it works
Selank is a synthetic analog of the immune peptide tuftsin, researched for anxiolytic and nootropic effects.
Tuftsin
Built on an immune peptide
Selank extends tuftsin, a natural immune signaling peptide, into a more stable seven-amino-acid analog.
GABA
Touches the calm channel
Preclinical research suggests selank modulates GABA signaling, the brain's main inhibitory system.
Anxiety
Studied for stress response
The peptide is researched for anxiety-related behavior in models, without the sedation profile of classic anxiolytics.
Key benefits
- Focus-and-mood research covering calm, stress response, and clarity.
- Protocols studying steady focus without heavy stimulation.
- Studied as a calming nootropic option rather than a stimulant.
Laboratory research only. Not for human or veterinary use.
What published research is studying
Early human data- Anxiety and asthenia symptoms in adults with generalized anxiety disorder and neurasthenia
- Whether adding it to a benzodiazepine changes response speed and reported side effects
- Enkephalin half-life and cytokine expression in patients with anxiety-asthenic disorders
- Expression of GABAergic neurotransmission genes in rodent brain
Human evidence is limited to small Russian studies, mostly open or active-comparator rather than placebo-controlled, and none has been replicated in a Western randomised trial.
Key research findings and references
Key research findings
In the same study, serum leu-enkephalin half-life was reduced at baseline and rose during selank administration, correlating with lower anxiety scores in the generalized anxiety disorder group.
Zozulia AA et al., Zh Nevrol Psikhiatr Im S S Korsakova 2008In a study of 70 patients with anxiety disorders, adding selank to phenazepam accelerated the therapeutic effect. Reported sedation and cognitive side effects were lower than with phenazepam alone.
Medvedev VE et al., Zh Nevrol Psikhiatr Im S S Korsakova 2015In rat frontal cortex, selank altered expression of 45 of 84 neurotransmission-related genes at 1 hour after administration, with 22 still altered at 3 hours.

- Healthy-volunteer imaging study: resting-state fMRI recorded before, 5 minutes and 20 minutes after a single injection in 52 participants (Panikratova et al. 2020).

Research endpoints
- Hamilton Anxiety Rating Scale score
- Zung self-rating anxiety score
- Clinical Global Impression rating
- Serum leu-enkephalin half-life
- Resting-state functional connectivity of the amygdala

Research handling
Full handling guide- 01
Lyophilized, sealed, batch-numbered
Each vial ships as a freeze-dried powder under an inert seal, tied to the batch on its Certificate of Analysis.
- 02
Store cold and dark
Unopened vials are kept refrigerated at 2-8°C away from light. Reconstituted material is stored refrigerated and used within the window the research plan defines.
- 03
Reconstitute with bacteriostatic water
The included bacteriostatic water is added slowly down the vial wall and the vial is swirled, never shaken.
- 04
Research use only
Supplied for laboratory research. Not for human or veterinary use. Handle with the personal protective equipment the laboratory requires.
