Serious Mass - The Ultimate Weight Gain & Muscle Building Formula

Weight gain goals require serious calories. For those with highly active metabolisms, weaker appetites, or on-the-go lifestyles, getting enough calories from food alone to pack on muscle can be a major challenge. Serious Mass by Optimum Nutrition provides the ultimate solution, delivering a massive, nutrient-dense dose of calories and protein to help you break through plateaus and build real size and strength.

Key Benefits & Features:

• Massive Caloric Support: Delivers 1,250 calories per serving (when mixed with water) to easily help you achieve the caloric surplus needed for significant weight gain.
• High-Quality Protein Matrix: Packs 50 grams of blended protein to support muscle recovery and continuous growth.
• Fuel for Intense Workouts: Supplies over 250 grams of carbohydrates (with no added sugar) to instantly refuel glycogen stores and power you through the heaviest lifting sessions.
• Enhanced for Performance: Fortified with 3 grams of Creatine Monohydrate to maximize strength output, plus added Glutamine for optimal recovery and anti-catabolic support.
• Comprehensive Nutrition: Packed with 25 essential vitamins and minerals to support daily health, immunity, and overall metabolic function.

Usage & Supplement Stacking:

Add 2 heaping scoops to a blender filled with 24 fl oz of cold water or milk and blend until smooth. For new users, it may be beneficial to begin with a 1/2 serving (1 scoop) daily for the first week. Consume between meals to support a high-calorie diet, post-workout for recovery, or before bed. It works perfectly alongside your daily Opti-Men multivitamin to ensure total nutritional coverage as you push for maximum muscle mass.
