Mass Gainer Protein

Mass Gainer Protein is built for one goal, to help you gain size, strength, and lean mass when your regular diet isn’t enough. Designed for athletes, hard gainers, and anyone with high energy demands, mass gainers combine quality protein with complex carbohydrates and essential nutrients to support muscle growth and recovery.

While standard protein powders focus on lean recovery, Mass Gainers are formulated for calorie surplus. They deliver a balanced macronutrient profile, often containing 20–50 g of protein and 80–200 g of carbohydrates per serve, to help you hit your daily intake targets without the hassle of eating huge volumes of food. This makes them ideal for those who struggle to gain weight or fuel intense training schedules.

The protein component (usually a blend of Whey Concentrate, Whey Isolate, and Casein) supports muscle repair, while the carbohydrates replenish glycogen stores and create the calorie surplus needed for growth. Many also include added creatine, MCT oils, or digestive enzymes to further enhance performance and nutrient absorption.

Mass Gainers are most effective when used strategically, such as post-workout, between meals, or before bed, to maintain a steady flow of calories and amino acids. When combined with consistent training and a well-structured nutrition plan, they can help you build lean size without unnecessary fat gain.
