The Optimum Nutrition Day & Night Fat Burning Stack combines the stimulant / caffeine based burn complex thermogenic with the non stimulant / no caffeine burn complex thermogenic. It allows users to have the choice of something caffeinated or not depending on the time day you train and personal requirements.
For example, you might normally train in the morning so would use the caffeinated burn complex for a bit of an energy kick. One day you might not be able to get to the gym till late afternoon and don't want to ingest a heap of stimulants close to bed, enter the no caffeine burn complex thermo.
Another alternative is to simply go halves with a friend, one gets the stim-based fat burner, the other gets the no-stim fat burner, saving you both some extra dollars!
