What Selank is
Selank is a synthetic heptapeptide analog of the immune peptide tuftsin, developed in Russia as an anxiolytic. It is studied for reducing anxiety without the sedation, cognitive impairment, or dependence associated with benzodiazepines. It is approved in Russia but not in the United States.
Research depth: 2/5 Approved in Russia with regional clinical studies; limited Western replication and not FDA-approved. Human trials: Regional trials. This measures how much has been studied — counting animal and laboratory work — not whether it works for you.
How Selank works
It appears to modulate GABA signaling and the balance of neurotransmitters involved in anxiety, and it influences the expression of some neuropeptides and immune signals. Its precise mechanism is not fully characterized. Unlike benzodiazepines it does not appear to cause sedation or dependence in available studies.
Selank side effects
Commonly reported
- Mild nasal irritation with intranasal use
- Generally reported as well tolerated
- No robust Western safety data
Serious — seek medical care
- Evidence base is largely regional with limited Western replication
- Mechanism and long-term safety not fully characterized
- Not FDA-approved; products in the US are unregulated
This list is not exhaustive. Report anything unexpected to the clinician who prescribed it. If you have severe abdominal pain, trouble breathing, or signs of an allergic reaction, seek care the same day. See also our guide to peptide side effects by class.
A worked example
A 10 mg vial reconstituted with 1 mL of bacteriostatic water gives 10 mg/mL. A 500 mcg dose is then 0.05 mL — about 5 units on a 100-unit insulin syringe, giving roughly 20 doses per vial before accounting for residual volume left in the vial and syringe.

Common questions
Is Selank approved in the US?
No. Selank is approved in Russia as an anxiolytic, but the FDA has not approved it, and its evidence base is largely regional with limited Western replication.
How does Selank work?
It is a synthetic analog of tuftsin, an immune-related peptide, studied for anti-anxiety effects without the sedation or dependence of benzodiazepines. The exact mechanism is not fully defined.
