Serious Mass 12 Pound Weight Gainer Powder - Banana Flavor

Our review of Serious Mass 12 Pound Banana by Optimum Nutrition finds it best suited to lifters and hard gainers who need a straightforward, high calorie shake to add mass fast. The single biggest reason to buy is its massive per serving nutrition profile: each two-scoop serving delivers over 1,200 calories, 50 g of protein and more than 250 g of carbohydrates, making it a practical tool for anyone struggling to hit a daily calorie surplus. This is a functional, no-frills mass gainer built around quantity of calories and macronutrients rather than novelty ingredients.

Key Features

• High calorie blend: Provides around 1,260 calories per two-scoop serving to help you consistently exceed daily energy needs for weight gain.
• Protein content: Supplies 50 grams of blended protein per serving to support muscle repair and growth when used alongside resistance training.
• Carbohydrate dense: Delivers over 250 grams of carbohydrates per serving to refill glycogen and sustain caloric surplus for bulking phases.
• Added vitamins and minerals: Includes 25 vitamins and minerals plus creatine and glutamine to support recovery and overall nutrition.
• Versatile mixing suggestions: Can be blended with fresh or frozen fruit, peanut butter, or nuts to increase calories and flavor in an electric blender.

Who It's For

Serious Mass 12 Pound Banana is for experienced lifters, hard gainers, and anyone with a high daily calorie target who needs a convenient way to add large amounts of energy between meals or after workouts. It fits well for those following a structured resistance training program who want a trusted name and a straightforward mass gainer.

It is not ideal for people with low calorie needs, those watching carbohydrate intake closely, or anyone seeking a low-calorie or leaner recovery shake. Also avoid this if you need a flavor-free or low-sugar option; this product prioritizes calories over minimalism.
