This supplement is low carbohydrates only 6 grams per scoop. You will achieve more strength and muscle size gains if you have plenty of carbohydrates after your workouts to restore glycogen in the muscles. Glycogen is the primary fuel for most bodybuilding exercises. This will protect your muscle mass gains from being used for fuel during longer workout sessions. You should ask a dietician about your supplements to find out whether they are complete(you might think that protein is protein but imbalanced amino acids can be dangerous and useless for bodybuilding). If you have eaten a lot of carbohydrates the night before a workout you might not need any extra before your workout but it could give your muscles a boost of energy for a more effective workout.
