Lean Mass Gains: Over 1,000 Calories per Serving! 

1010 Calories Per Serving

University Research-Based Science For Maximum Mass: Quickmass® packs 1010 Mass-Building Calories into every serving in cold water, no milk required! During one 8-week Gold-Standard (double-blind, placebo-controlled) study conducted at California State University, test subjects provided the same calorie content as 2 servings of Quickmass® per day gained 4.5 times as much fat-free mass and increased chest size by 1 inch.


60 g of Sustained Release Protein to Build Mass: MassPro™ creates a rapid and sustained delivery of muscle-building proteins that work continuously all day to help you recover and grow. Power up your Muscle Protein Synthesis and fuel your lean mass gains!

Carb Plex

Optimal 3:1 Carb to Protein Ratio: CarbPlex™ provides the calories your body needs to grow All Day with ultimate Mass Fuel for your gains! The Quickmass® carbohydrate blend is powered by healthy, long-chain and complex carbohydrates such as sweet potato, rolled oats and quinoa along with scientifically studied and tested carbs like Cyclo-D™ and VitaFiber™, a natural prebiotic.

NP5 Technology

Calorie Absorption Complex: Enhance your lean mass gains by absorbing nutrients better. Rapid gains in lean body mass depend on dramatic increases in calories and absorbing them! Patented Cinnulin PF®, a natural extract of cinnamon, dramatically enhances that way your body absorbs calories. Along with natural extracts of Prickly Pear and Bitter Melon, Quickmass® helps you absorb the highest quality nutrients efficiently to turn calories into Mass.

Suggested Use

Blend, mix or shake 1 to 4 rounded scoops (~66 g to 264 g) with ~4 oz (~120 ml) of cold water per scoop. For 4 scoops ~16 oz (~500 ml) should be used. Add the water first, then Quickmass® when preparing. For best results, it is recommended to take 4 rounded scoops twice daily for an 8-week period. As an option, cold milk can be used instead of water, but it is not required.
