About Phenibut
Phenibut is a GABA-B agonist sold as a supplement in some markets. It is not part of the standard 5-, 10- or 12-panel or DOT tests.
Detection requires a dedicated assay; routine workplace panels will not identify it.
Its effects overlap with alcohol and benzodiazepines clinically, but it is a distinct compound and is not detected by benzodiazepine screens.
