Hell yeah bro!! i first heard of this from Dan Duchaine!! i was "recommending" it to all the strippers that i trained!!! they loved the shit!!! the first time i did 2/25mg ephedrine, 1 adult aspirin, and i vivarin(300mg caffiene?) i went to the gym, damn near tore the gym down. started seeing white and yellow dots but didnt care!! i made 4 new friends during the workout because i couldnt stop talking.....increased my bench and db presses....best workout ever! then i went home and crashed for about a 4 hour "nap".
It works well to give energy and the ephedrine helps preserve muscle. I use asprin couse its supposed to give a longer effect. I take 25mg e, 200mg c, 325mg a. It only lasts me 3hours. I take it 3 times a day.
