Extreme calories. Extreme growth. Built for the hardest gainers.
Boditronics Mass Attack Heavyweight is engineered for anyone who struggles to gain size — those with fast metabolisms, high training demands, or anyone needing serious calorie support. Each serving delivers an enormous 1300+ calories (when mixed with water), packing in 60g of high-quality protein, complex carbohydrates, and MCT fats to fuel rapid mass and strength gains.
This heavyweight formula also features the Heavyweight Gain Stack: a precise blend of dextrose monohydrate and Creatine Monohydrate for enhanced ATP replenishment, power output, and muscular growth. Designed to mix easily — without the overly thick texture found in many gainers — it delivers clean calories, zero artificial colours or preservatives, and delicious flavours that make mass gaining easier than ever.
Mix 300g (four slightly heaped scoops) with 300ml water or milk in a shaker or blender. Shake vigorously for 20–30 seconds. For best results, consume 2 servings daily. Do not exceed the stated dose.
