Mass Gainer is a simple — and clean — way to go from skinny to stacked. It’s fully stocked with 810 calories, 50 grams of muscle-building protein, and 133 grams of carbohydrates. Probiotics help your body utilize the protein to its fullest. So, if you can’t seem to get enough mass-making nutrition in your day, skip the drive-thru and have a rich, satisfying shake.

Carbohydrates are key for a mass-gaining diet. They provide your muscles and liver with the fuel you need to lift big and train hard. Maltodextrin provides fast-digesting carbohydrates while ModCarb and Cluster Dextrin provide slower-releasing carbs that have less of an impact on blood glucose levels.*

Fat is not the enemy! It’s a valuable tool for clean bulking. Our bodies need some fat to produce hormones, build cell walls, absorb fat-soluble vitamins, construct neurons, and carry out many other important functions.

The probiotics in our Mass Gainer have been developed specifically for use in powder supplements. When you’re on a mass-gaining diet, a little digestive health support goes a long way. And, of course, protein absorption is crucial to making lean muscle gains.*


Add one serving (3 scoops) of Signature Mass Gainer to 16 oz. of cold water and shake well until dissolved. Adjust the level of liquid used to modify the flavor and thickness to your preference. If one full serving exceeds the capacity of your shaker bottle, mix 1/2 serving (1.5 scoops) with 8 oz. of cold water and consume two shakes throughout the day. To mix your gainer into a smoothie, combine with water (or beverage of choice) and frozen fruit and mix in a blender until you reach the desired consistency.
