How to Use

Important Information
Critical Mass is a dietary supplement, not a replacement for a balanced diet. Results depend on your overall calorie intake, protein intake, training, recovery, and consistency.
If you're trying to gain weight, remember that a mass gainer works by making it easier to consume more calories. It doesn't automatically build muscle without appropriate resistance training and nutrition.
