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.

This champion blend weighs in at 750 calories, 50 grams of fast, medium and slow absorbing proteins and a 124 gram blend of important carbs - and the amounts are even higher when mixed with milk. That's science-based on nutrition for advanced muscle performance.

The extras - Beyond The Basics: Wait. There's more. This motherload of mass gainers is enhanced beyond basic nutrition. Infused with functional blends of ingredients and technologies - this formula offers an arsenal of advantages....

Formula re: Contains

Tri-MG Infusion - This anabolic blend consists of clinically studied Betaine (a.k.a trimethlyglycine) and HMB. This combination of ingredients creates an anti-catabolic effect for your muscles. Micronized Amino Acids - Using MicroSorb amino technology, the amino acids added to this formula are pulverized, or "micronized" from large molecules into smaller particles to facilitate faster absorption. Why is that important? Better absorption of amino acids means better muscle fuel. These key amino acids, including Glutamine, Arginine and Leucine, all support muscle protein synthesis and other key processes crucial to gaining mass. Creatine Matrix Blend - For added muscle benefits, this matrix includes 3 forms of creatine, plus other ingredients your body uses to make creatine. Creatine helps to improve training results, support immediate energy production during exercise and is important for muscle protein synthesis.
