Selank: How It Works, Uses, and Evidence
Evidence checked by HealthRX.com Editorial Team · Last evidence check
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 and has no current 503A bulk-substance pathway. Products sold as research chemicals are not approved or quality-assured for human use.
How to get Selank online
Selank is available through HealthRX.com after an online visit with a licensed provider, who reviews your history and, when appropriate, issues a prescription that a licensed US pharmacy dispenses and ships to you. Selank starts at $114 per 15mL nasal spray.
Because Selank is a anxiolytic neuropeptide and prescription-only, it cannot be bought over the counter. What you pay depends on the dose and quantity your provider recommends. You can begin the online visit in a few minutes and are only prescribed if a provider determines it is appropriate.
