▀In an eight-week, randomized, double-blind, placebo-controlled study of healthy male volunteers, 18 subjects completed 3 sets of resistance training (RT) daily + the macronutrient blend in Mass XXX™, and 16 subjects performed 5 sets RT daily with no supplement. After eight weeks, subjects on the supplement showed equal gains in body weight, fat free mass (FFM), maximal muscle strength (MMS) and muscle endurance (ME) with only 3 sets RT per day compared to the control group who completed 5 sets RT per day.

^When used in conjunction with an exercise program.

•In a 8-week randomized, double-blinded, placebo-controlled study of 118 healthy men participating in a supervised resistance training program showed that those taking MyoTOR® had significant increase in upper body strength (49.7 lb. vs. 19 lb.), mean lower body strength (42.1 lb. vs. 19,2 lb.) and muscle endurance after 8 weeks vs. those who took the placebo with the same exercise. Improvements in strength were seen in as early as 2 weeks. Men on MyoTOR® had greater improvements in muscle strength and upper body endurance vs. those who took a placebo but exercised twice as much.

 ♦An 8-week randomized, double blind, placebo-controlled study of 40 healthy men participating in a voluntary exercise routine showed that those taking MyoTOR® had significant improvements in upper and lower body strength, muscle endurance, arm circumference and lean body mass vs. those on a placebo after 8 weeks Improvements in strength were seen in as early as 2 weeks.
