• Provides 50 g protein per serving to support muscle growth and repair.
• Supplies over 250 g carbohydrates to provide substantial energy and caloric density.
• Includes 3 g added creatine per serving to support performance during intense training.

Active Ingredients That Matter:

50 g high-protein content to support muscle growth and repair; over 250 g carbohydrates to supply substantial calories and energy; 3 g added creatine to support performance; and 25 vitamins & supplements to contribute to overall nutritional support.

How To Use:

Add two heaped scoops of Serious Mass (334 g) to a blender filled with 710 ml of water and blend for 45–60 seconds. Add a few ice cubes and, if desired, other calorie-contributing ingredients, then blend for a further 30–45 seconds. For a thicker, creamier, higher-calorie shake, mix two scoops with 710 ml of non‑fat or low‑fat milk instead of water. New users may prefer to begin with ½ serving daily for the first week, then gradually increase to one or more full servings several times a day.

Suggested timing: drink ½–1 serving between meals to maintain a positive nitrogen balance; consume ½–1 serving 30–45 minutes post-workout to support recovery; or take ½–1 serving about 45–60 minutes before bed to provide nutrients overnight. For best results use Serious Mass alongside intense weight training (3–5 times per week) and a sensible whole foods diet, allowing at least 48 hours between workouts for the same body parts.

Best Suited For For lifters and hardgainers seeking a convenient, high-calorie solution to increase body mass, support muscle recovery and enhance performance when paired with structured resistance training.
