Supplements need to have a good foundation to work properly. As others have mentioned, if you had your diet in order you'd be seeing the fat draining off and the muscles bulking up without the use of any supplements. Supplements increase the effects of a good diet and workout (and even then only by 5-10%)... there's no possible way that they can do you any good if your diet isn't right. Most will tell you that diet's an even more important component than working out.
Also, to be clear, when we talk about a good/right/proper diet, we're not talking about that stupid triangle that the surgeon general puts out about a "balanced diet". Do some research. Figure out your resting metabolic rate, adjust for your activity level, and make sure you're taking in enough calories each day. Along with that, make sure you've got a good mix of proteins/carbs/fats, and that you're not eating ANY crap (you should know what crap is... basically anything you can get at a gas station, sugary sodas, candy bars, chips, fried foods, etc.)
We could all write a book on a right and proper diet, but it's been done before. Poke around the forums here and around google and start educating yourself on what, when, and how to eat. There's a lot to learn.
