THINK SMART – THINK CLEAN: The Clean Weight Gainer for Rapid Gains in Lean Mass!

MASS-OLOGY delivers 6 pounds of quality muscle building calories in this lean mass weight gainer formulated with ultra premium protein and slow release carbohydrates to fuel muscle growth. Where as most weight gainers are loaded with empty calories, excessive sugars and fats, MASS-OLOGY delivers clean nutrients that will help make the difference between gaining quality lean mass or unwanted fat mass!


Unlike other gainers in the market that use a high sugar and fat content to drive up their calorie count, MASS-OLOGY™ derives a much higher percentage of its calories from a blend of premium protein sources & complex carbohydrates containing dietary fibers, enzymes and lipids.

In addition, each serving packs 1,000 mg of Creatine Monohydrate, 1,000 mg Glutamine and a superior full spectrum Vitamin and Mineral profile as well as a blend of Four Digestive Enzymes ensuring proper digestion without bloating and discomfort.

50 Grams of High Quality Muscle Building Protein Per Serving!

MASS-OLOGY delivers a blend of 3 premium proteins providing a full spectrum of amino acids to support muscle repair.

  • Fast absorbing and easy to digest hydrolyzed Whey Protein Isolate
  • Biologically active Whey Protein Concentrate
  • Slow absorbing “anti catabolic” Micellar Casein Protein

240 Grams of Slow Digesting Clean Carbs Per Serving!

Featuring 4 ultra clean carbohydrate sources providing sustained energy:

  • Cluster Dextrin®
  • Carb10®
  • Sweet Potato Powder
  • Waxy maize starch
  • Full Spectrum Multi-Vitamin & Mineral Blend

    MASS-OLOGY compliments a superior nutrient profile with a full spectrum multivitamin and mineral blend containing 23 vitamins and minerals in every serving! These micronutrients are essential for efficiently assimilating and processing proteins, carbs, fats as well as for muscle building and repair.*

    Outrageously Delicious & Tasty Mass Building Flavors

    MASS-OLOGY is available in two great tasting Chocolate and Vanilla flavors!

    Suggested Use:

    Mix 1-3 scoops in 8-12 oz of water or your favorite beverage and consume 1-3 x daily. Some athletes will consume an additional scoop with meals to increase overall quality calorie content, or between meals to ensure steady supply of nutrients into the system for muscle building and recovery.

    Pack on Clean Mass from Quality Calories with MASSOLOGY!
