It's Lisdexamphetamine. Significantly more useless as a recreational drug then Adderall, but take enough and it HAS to work, after all, it is amphetamine. A 25mg capsule has 7.425mg dextroamphetamine (i.e., "the good stuff"). Seems to be time-release though. That'll keep you awake forever. In my opinion dextroamphetamine's good effects aren't worth the bad.
