Adderall XR vs. Adderall IR vs. Dexedrine (IR/ER) for Studying Purposes?

[Stimulated]

Which is best for studying? Adderall XR, Adderall IR, or Dexedrine (IR or ER)? And why?

Thanks!

it all depends on how long you want to study for. I think dextroamphetamine would be the best because there is supposedly less jitteriness and more mental focus, but it's all a matter of opinion. I would also go with an extended release formulation for smoother and longer effects.
