It really depends on what you are looking for - whether you are trying to lose a few pounds or you are a body builder and this is your career. There are just so many products out there that you really have to see what is going to work best for you because everyone will react differently to these products so what may work great for someone may not work at all for you. Do not get discouraged just do some more research and keep trying and in the meantime you just eat healthy and work out on a regular basis whether it is a walk once a day or aerobics at a gym.
