Think of it this way. You can build muscle and lose fat. It is hard to do both at the same time but it can be done. As for “tone” muscle. that is mostly a function of losing body fat. If you increase muscle as well you can “tone” muscle. Bottom line it Diet is key…eat clean and a lot of protein…stay away from white carbs and you should be fine. After eating like this you can get idea how much you need to take in to either lose fat or gain muscle. Creatine is fine to take…but don’t expect anything that noticeable.
People shouldn’t bee too concerned with supplements until their diet is in check. Yor diet will make the #1 difference in your body, combines with a solid lifting plan of course. Once your diet is in check then I would worry about supplements.
