Do you know the concentration of the solution?
If you do take 1 mg, if you feel really good and not that sleepy it's clonazolam if you feel really good and very sleepy for a long time it's flubromazolam and if you feel really fucking awesome, very sleepy but it doesn't last long (only a few hours the other two last much longer) it's flunitrazolam.
The other rc benzos are either boring (diclazepam, pyrazolam, cloniprazepam, ...) and don't make you feel good or too weak to do anything with 1 mg (fonazepam, flubromazepam, norflurazepam, etizolam, nitrazolam ..).
Or you could send it to a lab to be tested.
