Yes I have been on most of the stimulant meds. I can tell you for a fact that Dexedrine has much less body load and more mental stimulation. Don’t get me wrong, speed is speed but d-amphetamine (only chemical in Dexedrine)is much cleaner and L-amphetamine (which adderall is 50% of) is basically garbage. Max daily dose of Dexedrine is 40mg compared to 60mg adderall because Dexedrine is stronger than adderall. Probably start around 5mg 2x day.
