Stimulants Mixed Amphet Salts 30 mg xr

[amphetamien]

Hello everyone,

today i purchased 3 generic adderall pills, they look like this: http://www.drugs.com/imprints/m-amphet-salts-30-mg-15896.html
I've only ever taken Adderall 20mg xr, but i want to know how long i will feel the effects of this pill, which is 30mg. Some websites are telling me 4-6, and others are saying 12 hours. Does anyone know from personal experience how long this pill would last me if i were to take it tomorrow morning around 8?

an xr adderall is extended so its 12.

Bet on a solid 12 hours of stimulation, with about 4-6 of them actually being the classic euphoric speed high. Don't bet on sleeping until after midnight regardless.
