- 3 Sets + Mass XXX = 5 sets
Equal gain in mass, muscle strength and endurance
In an eight-week, randomized, double-blind, placebo-controlled study of healthy male volunteers, 18 subjects completer 3 sets of resistance-training (RT) daily + the macronutrient blend in Mass XXX, and 16 subjects performed 5 sets RT daily with no supplement.
