I only use caffeine and beta alanine personally. A $20 tub of beta alanine has 250 servings and lasts almost a year. Caffeine is only a couple bucks.

"When your vision is powerful enough, everything else falls into place: how you live your life, your workouts, what friends you choose to hang out with, how you eat, what you do for fun. Vision is purpose, and when your purpose is clear so are your life choices. Vision creates faith and faith creates willpower. With faith there is no anxiety, no doubt - just absolute confidence." - Arnold Schwarzenegger
