I have tried almost every diey pill an diet fad out there. I just started taking it about 3 weeks ago amd have lost 5 lbs going to the gym almost every day doing cardio and using hydroxycut shape. I am currently taking alli and hydroxycut, and they work great! With hydroxycut, i have the evergy to get up and go for a run and workout and get things done. I only take it in tha AM because sometimes i feel it keeps me from going to bed. It also seems to reduce mt appetite. because i would rather be doing something energetic than eating. Weird, but it Does reduce my appetite. Never wrote a review on anything, but this product is so good, i had to.
