Medically reviewed by Dr. Jonathan Snipes, MD. Last reviewed September 23, 2026.Also available: Semax/Selank Nasal Spray, Semax Nasal Spray
What It Is
Selank is a heptapeptide developed in Russia from tuftsin, an immune-system peptide, extended to slow its breakdown. This spray contains Selank alone; the Semax/Selank spray pairs it with Semax.
How It Works
Selank is studied for shifting GABA-related gene expression and serotonin signaling, which is the basis for its use for anxiety without sedation. Intranasal delivery reaches the central nervous system without an injection.
Who It's For
Patients who want Selank's calm, non-sedating support on its own, without Semax's stimulating cognitive component.
Who Should Avoid It
Flag if on lithium. Discuss with provider if on psychiatric medications. Avoid with active psychosis or pregnancy.

Common questions about Selank Nasal Spray
- What does Selank do?
- Selank is a synthetic peptide derived from tuftsin, developed in Russia and used there for generalized anxiety. It is studied for its effect on GABA-related signaling and is used for calm focus without sedation. Western clinical data is limited, so expectations should be set with your provider.
- What is the Selank dosage?
- The pharmacy's direction is 1 spray in each nostril once daily. Each spray delivers 250 mcg, so that is 500 mcg a day. The Russian clinical protocol is a 14-day course followed by a break to re-evaluate, and your provider sets the course length.
- What are the side effects of Selank?
- Selank is generally well tolerated and is non-sedating. The most common effects are mild nasal irritation at the spray site and occasional headache. Tell your provider if you take lithium or other psychiatric medications, and avoid it during pregnancy or while nursing.
- What is the difference between Selank and Semax?
- Selank is used for anxiety and calm focus; Semax is used for focus and cognitive support. RxPepsDirect prescribes each on its own at $125 per 15 mL spray, or both together in the Semax/Selank spray at $150. Use one format, not a single spray and the combo together.
- How long does a bottle of Selank last?
- The 15 mL bottle holds far more than a month of sprays, but the pharmacy assigns it a 35-day beyond-use date, so plan on one bottle about every five weeks and discard any left after the date on the label.
