Supplements you use- bodybuilding/weightloss

The common answer here seems to be cardio, lifting, diet (not dieting), and a strict regimen. I have taken several biology, anatomy, and physiology classes, and one intense nutrition class geared for the medical profession, and all of these would agree with this common answer. There are few supplements that can do for you what proper nutrition, your own body, and proper exercise cannot. In fact, most supplements, protein especially, can be quite harmful, and none of them work without exercise and proper nutrition.
