Up Your Mass XXXL 1350 By MHP - Weight Gainer

What Is It?

MHP Up Your Mass is a nutrient dense weight gainer packed with 1350 calories. Each serving provides 50 grams of fast acting and sustained release protein to help you build muscle mass, increase strength and boost recovery.† With zero added sugar plus healthy carbs from sweet potato, oat fiber and quinoa, Up Your Mass XXXL 1350 is the ultimate mass gainer!

How Does It Work?

The protein matrix contains fast-digesting proteins (Whey Protein Concentrate, Whey Protein Isolate and Hydrolyzed Whey Protein) along with slow digesting proteins (Micellar Casein and Milk Protein) to provide around the clock nitrogen retention benefits.

Up Your Mass XXXL 1350 delivers 250 grams of complex carbs (Micronparticulated Maltodextrin, Sweet Potato, Oat Fiber and Quinoa) and functional fats such as MCTs, EFAs and CLA.

 MHP Up Your Mass helps create the perfect physical environment for maximum gains.
