i've been taking stacker 2 ephedra free for about two months now...and it hasnt done sh*t for me...i've taken it after meals and before my workouts, but all i've noticedis that it gives me an energy boost, but i havent really noticed that i've burned too much exess fat...i dunno if its just me, or if any of you guys have tried S2 also and have had similar results(or lack there of)...(i'm pretty slim, i'm 5-5 ish, 135, i'm not fat by any means, but i just wanted to lose tht extra weight...but i think i got jipped out of 40 bucks for the stacker)....
