aderol stack

Hi guys, I just got prescribed and started taking aderol. It makes me concentrate better, but one of the more positive notes about it is that its a stimulant. I was thinking maybe since the doctor took away my ECA stack (thermogain) that I could make my own similar ECA stack. I was thinking Caffiene Aderol and Aspirin. what else would work well with aderol? and anyone know how safe it is? Thanks for all your help. and sorry for being a newbie, but i am reading a lot and trying to catch up.
