Extreme Mass

Extreme Mass by International Protein is a high-calorie, nutrient-rich formula designed to support serious lean mass and size gains. Perfect for hard gainers and active individuals, it combines five premium protein sources with complex carbohydrates and a blend of healthy fats, including MCTs, canola, and sunflower oils. This combination ensures a steady supply of energy and nutrients to fuel training, support recovery, and maintain an anabolic state for muscle growth.

Unlike typical carb-heavy gainers, Extreme Mass delivers a balanced macronutrient profile, providing concentrated calories without excessive sugars. The five-stage protein blend—including hydrolysed whey, WPI, WPC, micellar casein, and egg albumen—offers varied absorption rates for sustained amino acid delivery. Carbohydrates from rice starch and glucose polymers offer both immediate and long-lasting energy, helping to support intense workouts and fast metabolisms.

Ideal for athletes, bodybuilders, tradies, and anyone with high energy demands, Extreme Mass is also suitable for those recovering from illness or needing extra calories. It’s a convenient, delicious solution for building lean mass and achieving serious growth.

Add 100g (3 scoops) of Extreme Mass and 500ml of low-fat milk or soy milk into a shaker or blender. You can even add other food such as banana or berries for an extra energy boost. You can have a serving of this supplement 2-3 times daily in addition to your regular meals for all your nutrition needs when you need to gain weight. The best times to take it are mid-morning, mid-afternoon, and before sleep, or whenever you need an extra hit of calories
