Mass gainer for easier calorie intake

Mix 4 scoops (240g) with 500 - 1000ml of milk or water and shake well using a shaker bottle. Consume 1-25 servings daily depending on your calorie requirements.

Each serving provides 54.9g of protein and 917 (240.0g serving). This macro profile suits anyone looking for a lean protein source that supports daily intake without excessive calories.

Each pack contains 25 servings, with a 240.0g serving size. Mix with water or milk as part of a daily routine around training or between meals. Consistent use tends to deliver better results than sporadic intake.

Frequently Asked Questions

Why does Critical Mass Original contain 80g of sugar per serving?

The sugar comes from maltodextrin and fructose, which are the primary carbohydrate sources in this formula. These fast-digesting carbs are included to maximise the calorie density per serving (917 calories). For hard gainers, the rapid energy from these sources helps push the body into a caloric surplus. If you prefer a lower-sugar mass gainer with complex carbs, Critical Mass Professional uses organic oats with only 2.9g sugar per serving.

How does Critical Mass Original compare to Critical Mass Professional?

Critical Mass Original provides 917 calories, 54.9g protein and 153.8g carbs with 80.8g sugar per 240g serving. Critical Mass Professional provides 566 calories, 42g protein and 74.7g carbs with just 2.9g sugar per 150g serving. The Original is for pure calorie surplus. The Professional is for a more balanced mass gain with lower sugar. Choose based on whether maximum calories or carbohydrate quality matters more to you.

Can I use Critical Mass Original if I am not an extreme hard gainer?

You can, but the 917-calorie serving may be excessive if you gain weight at a normal rate. Taking half a serving (two scoops instead of four) still gives you approximately 460 calories and 27g of protein, which is more manageable. For most people looking to gain lean mass, Critical Mass Professional at 566 calories per serving with lower sugar is the better daily option.
