The main components of heavy muscle powder and muscle-increasing powder are protein and carbohydrate, but the difference is that the content ratio is different. Protein content of heavy muscle powder is about 15%, and protein content of muscle-increasing powder is about 30%. The function of muscle-increasing powder is to increase muscle weight, while the weight-increasing ability of heavy muscle powder is stronger. At present, muscle gain powder or whey protein powder is the main products in the market, such as the famous muscletech and Oportmont. There are no direct stores of foreign brands in China, but these online and offline PQfitness do.
