Cellucor C4 Mass is a revolutionary pre-workout that is not only a powerful pre-workout but a potent mass builder as well. Extreme energy and a special carb matrix designed to stimulate muscle growth, this is the new definition of pre-workouts - C4 Mass!
Don't waste your money The extra carbs are a waste. Very disappointed in product. Go with regular c4 before buying there other mixes. Reviewer: Mike jones from Knoxville, TN | Date: 12/7/2015 6:46:26 AM
