To OP:
If the vendor is try to sell you "benzodiazapine RC" it is most likely Phenazepam.
I have tried it and think its good, but will last a long time. I took it at midnight fell asleep at 3 and went to work at 230 the next afternoon still feeling the effects which are just like a valium. If you are going to get some make sure you have any good accurate scale because the difference between .5mg and 2mg is ALOT. If you have friend pushin xanax pills I would recommend that because it has more euphoria and standardized dosage. Have fun and be safe
