30mg Adderall vs GENERIC | ADHD Information

I have taken both Adderall and the generic brand.  I cannot tell a difference and have switched back and forth twice (because I couldnt believe I couldnt tell a difference, so I tried one more time!)  I take 10mg and have bought what you took--adderall vs. amphetamine salts.  I have been on this type of medication for over 8 months.  Hope this helps you out. 

My prescription is for 30mg of adderall (instant release) 1-2 times per day
(i'm a big guy, 205 pounds).

I have been getting the generic 30mg amphetamine salt combos, and I like
them for the most part. But I get my new prescription filled tomorrow, and
I'm wondering if I should try the *real* 30mg adderall.

Has anyone taken both and can write a quick analysis comparing the two
experiences? All I know is that I did try 10mg versions of both *real* adderall
and ampetamine combos, and there seemed to be a difference. But I don't
know if that was just placebo effect.

Thanks in advance!
