sorry for going back to creatine but i think you are wanting to lose belly weight taking protein alone will make you stomach look bigger because there is fat in the supplement it just depends on how much you take but the only thing that willl have is inscreased muscle size it helped me alot when i was fifteen i was taking it and i weighed about 125 and benched around 130 and back then it took me all the way up the weighing around 160 something and max benching 210 but i did it for about 4 months but in four months that is good good good gains
edit: and the burning is when your muscles are depleted and lactic acid comes the your muscles when you take creatine it gives your muscles more fuel and say you could do 8 reps of something and if you take creatine you could maybe do 12 or 13 without the burn starting to come
and thats bs whoever said creatine can hurt your nads if you dont drink water the only thing it would mess up is if you overdose and have too much in your liver for your body to process but that is the same with protein powder too but ya they are right about the water i was drinking like 8 bottles of it at school and had to use the bathroom between every class but im still a big fan of creatine
