Yeah caffeine won't help with regulated hormone production.

Other people covered it pretty well. So I will chime in on the butt. You can't really spot gain fat. You will gain it where you are genetically inclined to gain it. You can try massaging, but that is a slow slow slow process. Did I mention how slow it is. Your best bet is to build up the muscle. If you have muscle which is then covered in fat. It should give you a bubble butt. The best exercises for that a deep squats. Don't let your knees go forward. Then squeeze your bum on the way up to help isolate the muscle. You want the muscle big, so the more weight the better.

If you have a smith machine in your gym. I recommend using that, so it is easier to keep good form.

But you want to go a bit deeper.

Something like this would also be a good addition. There are also machines that can do the same motion.
