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.

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.

For hardgainers it’s about more than just calories when you’re looking to put on size. Mass Gainer has an ideal ration of protein, carbohydrates, and fats to privde everything you need to help pack on mass.* The probiotics also help with protein absoportion so you get the most out of your shake. Looking for an even higher boost? Mix with milk for additional protein.

“PROSERIES
A PROSERIES is a promise. A symbol of your identity. Your mark on the world. In 2002, Proseriessupplement.com was founded on a single promise: Trust. It’s who we are and it’s in our blood. Our PROSERIES line is built on the same promise. Every product is no-BS, transparent, filler-free, and formulated with effective doses of research-backed ingredients you can trust. We create the highest quality supplements, so you can focus on leaving a mark of your own.

TOTAL TRANSPARENCY
PROSERIES products are formulated with high quality ingredients at effective doses that we’re proud to share with you. We don’t hide anything in a “proprietary blend”, so you always know exactly what you’re putting into your body.

EFFECTIVE DOSES
An effective dose is the amount of an ingredient that has been shown to deliver results. Some supplement brands add a sprinkle of an ingredient just so they can say it’s in the product. PROSERIES supplements always include enough to get the job done.

RESEARCH-BACKED INGREDIENTS
Trendy, flash-in-the-pan ingredients come and go. But time-tested, gym-proven ingredients are what you need to help you achieve your fitness goals. That’s what you’ll find in PROSERIESproducts because that’s what works.”
