- In an eight week randomized, double-blind, placebo-controlled study of healthy male volunteers, 18 subjects completed 3 sets resistance training (RT) daily + GNC Pro Performance(R) Mass XXX(TM), and 16 subjects performed 5 sets RT daily with no supplement. After eight weeks, subjects on GNC Pro Performance(R) Mass XXX(TM) 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.

- While working to achieve mass gains, it is essential that you get enough calories, including a balance of quality carbohydrates, protein and fat. Falling short on any of these nutrients can obstruct your performance goals.

- Amino Acids are needed to build the various proteins used in the growth, repair and maintenance of body tissues such as skin, bones and muscle. BCAA help fuel your skeletal muscles, preserve muscle glycogen stores and help to reduce the amount of protein breakdown. Adding BCAA to your diet can be anti-catabolic and have a protein=sparing effect. Arginine is an essential precursor of nitric oxide and is involved in the body's natural formation of creatine.
