The optimal time for a serving of Muscle Mass is 30-45 minutes immediately after your workout. This timing is critical because your muscles absorb approximately 80% of the aminos and carbs necessary to help them grow during the two hour period immediately following exercise. Depending on your weight gain and caloric needs take Monster Mass as a snack or as a meal addition.

CytoSport products complement a healthful eating and hydration plan that, when combined with a balanced exercise program may contribute to healthy weight management and recovery from exercise.
