I order from powdercity.com and they include a measuring scoop with their supplements. That gives you a way to get the dosing. I would stay with the basics of creatine. You can get caffeine tablets anywhere to take pre-workout or just have coffee. Beta alanine may be helpful. You can mix the creatine and beta alanine into your shake since they don't really have any taste. They will just make it a little gritty.
