Diclazepam is often a 2-chloro derivative of your benzodiazepine diazepam. It includes a benzene ring fused to your diazepine ring, by having an R1 methyl group substitution and two substituted chlorine groups.it would not last too a lot longer than rx xanax but it's somewhat much better. took 20mg under the tongue. not even near to Clam. I like it
