You migh use one, or the other, but definitely not both at once. Both of these supplements are full of stims, and if you will use both, you will seriously overdo with them, and it is never good for your health. Besides, it may even become counterproductive for your training, and for your muscle growth on the long run.
I completely agree with @stevesmi - food is the best preworkout. Eat some good food reach in protein and carbs an hour before working out, and it will give you plenty of energy. Many do the mistake of trying to train without eating, and you can not train properly if you don't have the fuel to make your body work.
