I take it that since your taking stims, your goal is fat loss. You may be losing wieght, but i'd bet that your losing muscle as well. Your diet and pre/post workout nutrition need a lot of work IMO, and that much cardio is gonna make you go catabolic real quick.

Take a gander around here, there is a lot of info on fatloss and muscle gain. You picked the right place to educate yourself.
