Weider Super Mega 2000 contains a carbohydrate/protein blend. Carbohydrates provide you with energy, and proteins help you quickly build muscle mass. To gain muscle mass, you need to train intensely and consume more calories than you need to maintain your current muscle mass, as only excess calories can lead to an increase in muscle mass. Maintaining a balanced diet is essential, and Weider Mega Mass 2000 offers you the ideal composition to increase muscle mass. Mega Mass 2000 has been around for more than 40 years and has been continuously improved over the years, with the experiences of Weider champions contributing to these improvements.
