Adderall to Generic

[d775mm]

I used to take Adderall and I changed to the generic form. They say that both are the same, but so far I've been noticing a huge difference from one to another. Can anyone explain the difference or which one is the best to take? thanks

Not without you telling us the imprints or who mfr'd them, and how many mgs.
