Unapproved outside a few countries.

Basis: Clinical use in Russia and community reports. Educational only, not medical advice.

Medication concerns

Theoretical: no human interaction studies
  • Sedatives, anti-anxiety and sleep medicines (benzodiazepines, zolpidem)

    Calming peptides such as Selank may add to their effects.

  • Stimulants (amphetamine, methylphenidate, high-dose caffeine)

    Activating compounds such as Semax may add to stimulation, sleep loss or jitteriness.

  • Antidepressants, antipsychotics and seizure medicines

    Not studied together. Talk to the prescriber, especially with psychiatric or seizure conditions.

  • Everything else you take, including supplements

    Bring a full list of medicines and supplements to your pharmacist or clinician before starting.

Basis: No Western human interaction studies; concerns follow from reported calming or stimulating effects. Educational only, not medical advice. Never stop or change a prescribed medicine without your prescriber.
