Optimum Nutrition Serious Mass is designed for people who struggle to gain weight and muscle despite consistent training, offering a high-calorie chocolate powder that combines whey protein with complex carbohydrates in each serving. It's meant to bridge the gap when whole food alone isn't enough to meet your daily caloric and nutritional needs, whether you're a hardgainer or in intense training. The formula includes vitamins and minerals and mixes easily with water or milk for post-workout recovery or between-meal nutrition.
Key Ingredients
Whey Protein Concentrate provides a rich source of essential amino acids and branched-chain amino acids (BCAAs) that drive muscle protein synthesis and support post-workout recovery.
Maltodextrin is a fast-digesting complex carbohydrate that replenishes glycogen stores quickly and contributes the majority of the calorie content needed for weight gain.
Creatine Monohydrate (5g) is one of the most researched sports supplements, supporting increased strength, power output, and lean muscle mass accumulation during resistance training.
Vitamins and Minerals Blend includes 25 essential micronutrients such as Calcium, Magnesium, Iron, Zinc, and a full B-vitamin complex to support overall health, energy metabolism, and immune function.
Cocoa (Processed with Alkali) delivers the rich chocolate flavor and also contains antioxidant compounds that contribute to overall wellness.
