Myogenix AfterShock Critical Mass is a lean mass gainer containing high-quality calories your body needs to build muscle — not a fat gut. Critical Mass uses primarily zero-lactose Whey Protein Isolate and Milk Protein Isolate, which are easy to digest, while keeping an ideal 2:1 ratio of carbs to protein — 94g carbs to 60g protein per serving. Each 2-scoop (182g) serving delivers 700 calories, 9g fat, and a 5g Amino Stack of Micronized Creatine Monohydrate, MagnaPower™ Creatine, and L-Glutamine. In water, Critical Mass tastes amazing in Cookies N' Cream Milkshake flavor — make it even more delicious and calorie-dense by adding milk, fresh fruit, peanut butter, or oatmeal and blending. Mix one serving (182g) with 16oz of water and enjoy. 15 servings per 6.01 lb (2730g) bag. Contains Milk.†

Frequently Asked Questions
Is Critical Mass actually lactose-free?
Critical Mass uses primarily zero-lactose Whey Protein Isolate and Milk Protein Isolate, making it a meaningfully better option for lactose-sensitive individuals than concentrate-heavy gainers. The formula does include a smaller amount of Ultra Filtered Whey Protein Concentrate as part of the blend, so it isn't strictly 100% lactose-free — those with severe lactose intolerance should still exercise judgment.†Can I add anything to make Critical Mass more calorie-dense?
Yes — Myogenix specifically recommends adding milk, fresh fruit, peanut butter, or oatmeal and blending for additional high-quality calories beyond the base 700-calorie serving.†Do I need to add creatine or glutamine separately?
No — each serving already includes a 5g Amino Stack™ of Micronized Creatine Monohydrate, MagnaPower™ Creatine, and L-Glutamine built directly into the formula.†How many times a day should I drink Critical Mass?
Mix and drink after workouts or between meals to help build muscle and gain weight — frequency depends on your individual calorie needs and how much of a surplus you're targeting for your goals.†
How to Use Myogenix AfterShock Critical Mass

Who Should Exercise Caution with Critical Mass
Contains Milk — not appropriate for individuals with milk allergy; contains some lactose despite the primarily isolate-based protein blend
