Summary
Case reports and user accounts highlight a pronounced tendency toward myoclonic twitching and seizures, especially above approximately 200 mg or when combined with other CNS depressants; emergency benzodiazepines are advised to manage convulsions. Illicit samples may contain residues of the synthesis precursor 4-chloro-o-toluidine, which can cause methemoglobinemia and hematuria. Users report effects similar to GHB and carisoprodol with notable euphoria and muscle relaxation, but seizure risk limits therapeutic potential.
