well someone else would have to clarify this, but I have been on adderol before for the same reason you are, and since they are both stimulants, i would say they would hurt each others effectiveness. Its like drinking eneergy drinks on clen...no need to since clen already is 100x better, and it might actually effect how clen works. Not sure, someone else will have clarify and back me up on this. Phate knows alot, he might know the exact answer. I say dont, since stimulant + stimulant isnt very smart on the beta receptors. It would just down regulate them faster. Dont take my word for it though, let more educated members chime in before you make a decision.
