📋 Directions for Use

DIRECTIONS and USE Mix 4 scoops (150g) into 18-20 fl-oz water The optimal time for a serving of MONSTER MASS is 30-45 minutes immediately after your workout.

Depending on your weight gain and caloric needs take Monster Mass as a snack or as a meal addition.

Use as part of a well-balanced diet that includes whole foods and other protein sources. Do not use this product as your sole source of nutrition.

MASS GAINING FORMULA WITH mTOR ACTIVATORS Science confirms what athletes have always known: high quality calories and protein intake is linked to muscle size and strength.

Recent university research shows that Leucine enriched beverages consumed with exercise synergistically activates and prolongs activity of mTOR signaling pathway, which increases muscle anabolic potential (muscle growth)**.1,2,3
