Zantrex is great! my freind took it and she went from a size 9 to a 5 within 2-3 weeks but she dieted and worked out. Ive been taking 1 to start out just a for a couple days now and i dont feel anything which is great. im dieting and working out as well. soon ill move up to 2 pills. the only thing i notice is extra gas. but its great! i totally have faith!
