What Is Selank?
Selank is a synthetic peptide developed in Russia, based on tuftsin, a natural peptide involved in immune function. It's approved in Russia as an anti-anxiety medication and is typically used as a nasal spray.
It's marketed online as a calming peptide that may reduce anxiety without the sedation or dependence associated with benzodiazepines.
How Is It Thought to Work?
Research suggests Selank may:
- Influence the GABA system, which helps calm the nervous system
- Affect serotonin and other brain chemicals involved in mood
- Modulate immune signaling
What Does the Research Show?
- Small studies, mostly from Russia, have reported reduced anxiety symptoms in people with generalized anxiety disorder
- Some studies suggested effects comparable to certain anti-anxiety medications, with less sedation
- However, these studies are generally small and have not been replicated in large, independent clinical trials
How Does It Compare to Benzodiazepines?
Benzodiazepines (like alprazolam or lorazepam) work quickly for anxiety but can cause:
- Sedation and drowsiness
- Memory problems
- Dependence and withdrawal
- Risks when combined with alcohol or opioids
Selank is claimed to avoid many of these effects, but without large, rigorous trials, it's not possible to confirm that it's as effective or as safe as claimed.
Safety and Regulation
Selank is not FDA-approved. Its status for compounding was under review and changed during 2026, and it isn't fully settled. Long-term safety data is limited. Peptide regulations have changed several times in 2026, so a provider can help you understand current rules.
Proven Options for Anxiety
- Therapy: Cognitive behavioral therapy (CBT) is highly effective
- Medications: SSRIs and SNRIs are first-line treatments for many anxiety disorders, without the dependence risk of benzodiazepines
- Lifestyle: Regular exercise, sleep, limiting caffeine and alcohol, and mindfulness practices
If anxiety is affecting your daily life, talk with a provider. If you're in crisis, call or text 988 for the Suicide & Crisis Lifeline.

The Bottom Line
Selank shows early promise for anxiety with potentially fewer side effects than benzodiazepines, but the evidence is limited. Proven treatments like therapy and SSRIs remain the best-supported options.
