Selank: How It Works, Uses, and Evidence
Medically reviewed by HealthRX.com Medical Team · Last reviewed

What is Selank?
Selank is a synthetic peptide based on tuftsin, a small immune-signaling molecule, with changes that help it last longer in the body. It was developed in Russia, where it is used as a nasal treatment for anxiety and stress.
How does Selank work?
Selank is thought to act on the GABA and serotonin systems, influence BDNF, and slow the breakdown of the body's own calming peptides. These effects are proposed to reduce anxiety without the sedation or dependence associated with benzodiazepines, though the mechanism is not fully established.
What does the research show?
Russian studies report that Selank reduces anxiety, with some research comparing it favorably to standard anti-anxiety drugs for generalized anxiety disorder. Independent replication outside Russia is limited, so the strength of the evidence is modest and should be read with caution.
- Russian clinical research describes anxiety reduction, including in generalized anxiety disorder. [1]
- Selank is described as non-sedating and non-habit-forming in that research.
- Honest framing: large independent trials are lacking, so confidence in these benefits is limited.
How is Selank used and dosed?
Selank is given as intranasal drops or spray. Doses and concentrations vary by formulation and intended use, and there is no standardized regimen outside Russian clinical practice. Any use should be directed by a licensed provider.
Is Selank safe?
In available studies Selank has generally been reported as well tolerated, with nasal irritation as a possible effect. Independent and long-term safety data are limited, so its safety profile outside Russian clinical use is not well characterized.
Is Selank legal and FDA approved?
Selank is not approved by the FDA or in the European Union. It is available through compounding pharmacies and research suppliers, where product quality can vary, and it should only be used under medical supervision.
Frequently asked questions
Is Selank FDA approved?
No. Selank is not approved by the FDA or in the EU. It is used clinically in Russia and is available elsewhere only through compounding.
Does Selank help with anxiety?
Russian studies report anxiety reduction, including in generalized anxiety disorder, but independent trials are limited, so the evidence is modest.
Is Selank addictive?
Russian research describes Selank as non-sedating and non-habit-forming, but long-term independent data is limited.
How is Selank taken?
Selank is used as a nasal spray or drops, with doses varying by formulation and directed by a provider.
