I have NOT taken these but the testamonials sound great but also many said it did not work, so you have to wonder who if the ones it worked for actually took it or are working for the company and just putting out comments that it did work. Also the fact it says you do not need to do anything to lose the weight is something I would wonder about. I am 80 pounds overweight and if these worked without diet/exercise I'd be the first to take them. I will do a bit more research and if I find anything I will post again.
