Frequently Asked Questions

How many calories does Critical Mass provide per serving?

Each 150g serving delivers 566 calories with 42g of protein, 74.7g of carbohydrates (2.9g sugar) and 10g of fat. Mixed with 500ml of whole milk, the total reaches approximately 890 calories. For comparison, Critical Mass Original provides 917 calories per serving from a higher carbohydrate base, and Beef Protein Mass Gainer offers 452 calories per serving in a dairy-free format.

When should I take Critical Mass for best results?

The most common times are post-workout (when calorie and protein demands are highest) and between meals when you struggle to eat enough whole food. Some hard gainers also use it as a mid-morning or evening snack to add an extra 566 calories to their daily intake. Avoid replacing real meals entirely; Critical Mass works best as a supplement to a solid whole-food diet.

Does Critical Mass contain creatine?

Yes. Each serving includes 5g of creatine monohydrate, which is a full daily maintenance dose. On days when you take Critical Mass, you do not need a separate creatine supplement. If you also use a pre-workout like ABE (which contains 3g creatine), your combined daily creatine intake would be 8g. Consider reducing or skipping the standalone creatine on those days.
