Phenibut is a derivative of the inhibitory neurotransmitter GABA. It has been widely used for medical purposes in Russia and former Soviet countries, whereas it is a non-prescription and unapproved (though legal) drug in most other regions.

It has stress-reducing, anxiolytic, and sedative effects. At common doses it is often easier to be alert and functional on it relative to other GABAergic substances like benzodiazepines.
