One of the standout points of differentiation for Animal Pump is that it is one of the very few encapsulated pre-workout formulas, for those who tire of the traditional powdered drink mixes. Consequently, for those sensitive to caffeine or those who train at night, Animal Pump provides all of the stimulants in its formula in a single, easy-to-identify red capsule, further setting it apart from the competition. Leave the stims in, or take them out and save them for later. The choice is yours. That's flexibility you rarely find in traditional bodybuilding supplementation.
