International Mass Gainer Banner


International Protein Heavy Weight Mass Gainer is tailored to those with a high energy output or naturally fast metabolism. This product offers more carbohydrate than protein and still manages to deliver an epic 63.8 grams of quality protein per serve. If this isn't enough to get your taste buds tingling, a broad-spectrum digestive enzyme mix has been included to ensure the macronutrients are broken down properly for absorption.

After all, weight gain isn't just about what you eat, it's also about what your digestive system can handle. If gut function is poor, weight gain will be extremely hard to achieve. The digestive enzyme complex in Heavy Weight Mass Gainer helps to enhance overall nutrient absorption.


Carbohydrates are helpful nutrients that serve vital roles during mass gains programs. Firstly, they create an insulin spike, which is perhaps the most anabolic hormone we produce. Not only does insulin drive sugar into muscle cells, but amino acids as well. And these are the amino acids that we need for protein synthesis, or muscle repair and growth.


Secondly, carbs keep our body stocked-up on glycogen. We rely on glycogen, in part, for the energy needed during weight training, particularly higher repitition sets. This ensures we can power through sets and knock down reps quick smart.


This is another superb product from International Protein. Heavyweight Mass Gainer will have you wondering how you could ever have trainwed without it! Get ready to stretch out some shirts and size-up. Gains await!


How to Use International Protein Heavy Weight Mass Gainer

Mix 6 Scoops (220g) into 400-500ml Skim Milk. Ideally, taken immediately after exercise, and additional serves away from major meal times, such as morning tea, afternoon tea and before bed. Alternatively, for anyone not wanting to gain weight, a half serve (3 Scoops) can be  mixed in water and taken after intensive bouts of exercise (once daily) to speed up glycogen restoration and protein synthesis.
