I'm taking a stack of Hydroxycut Hardcore and Tonalin CLA (6 pills a day for both). I'm literally losing nearly 1lbs a day since last week. I went to bodybuilding.com and got some advice from someone their, he told me simply to cut out all simple sugars and bad carbs, and keep my "snacks" separated by 3hrs and they should be no more than 450 calories. I've cut my time at the gym from 2hrs to one, and I do calisthenics everyday for 30min. I think the stack is working, I haven't measured my bf but my bench went up to 240lbs now, and I can do 8 reps of 40lbs curls now.
