Is selank similar to benzodiazepines?

Selank enhances GABA-A receptor activity as a positive allosteric modulator (similar mechanism to benzodiazepines), but crucially without sedation, cognitive impairment, dependence, or withdrawal effects. Users feel relaxed while maintaining mental clarity.

Is selank approved anywhere?

Yes, approved in Russia and some CIS states for GAD as an anxiolytic and nootropic nasal spray. Not approved in any Western country.

How is selank typically dosed?

Research protocols use 250-500 mcg intranasally once or twice daily. Selank has poor oral bioavailability but is effective intranasally (bypasses first-pass metabolism) or subcutaneously. Acute anxiety effects within hours; chronic stress resilience improves over 2-4 weeks.

What is the recommended dose range for Selank?

The research dose range is Intranasal: 250–500 mcg per nostril, 2–3x daily; SC: 250–750 mcg daily, administered via Intranasal (preferred) or Subcutaneous, 2–3 times daily (intranasal); once daily (SC).

Boost Focus and Clarity with Selank and Semax Duo

Selank and Semax, synthetic peptides from Russian research labs, offer complementary cognitive benefits. Selank reduces anxiety and sharpens attention by balancing neurotransmitters and upregulating BDNF. Semax sustains focus through neuroprotection and neurotrophin enhancement, with studies showing improved memory under stress when used together.
