Good caffeine pill?

I work pretty early and sometimes take fat burners like IL SAW, IL Psychotic Diablo, or Synedrex for the various types of caffeine (Citrate, anhydrous, malate) to keep me boosted. The alpha yo doesn't bother me per se, but sometimes makes me unnecessarily aggressive/anxious.

Anyone have any caffeine pill recommendations specifically with citrate/malate? Theobromine is a plus too. Don't mind other nootropics either.
