What is Amplified Mass XXX™?
Need to pack on the pounds? AMPlify your gains with Amplified Mass XXX™ - our best mass gainer ever.* Exclusive to GNC, this rock solid formula is engineered with ingredients proven to help you increase lean mass, weight, strength and stamina.** Muscle up your diet with Amplified Mass XXX™ - the ultimate lean mass builder.

Amplified Mass XXX™ Evolution
What makes this product AMPlified? It all starts with basic science...

THE FOUNDATION - Science-Based Sports Nutrition:

Balanced Sports Nutrition + Training = Maximal Gains in Lean Mass and Performance

The science doesn't lie - without enough of the right carbs, quality proteins and healthy fats to compliment your training - you won't achieve maximal gains. The foundation Amplified Mass XXX™ provides a ratio of nutrients proven to accelerate increases in lean mass and exercise performance.** 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 2% milk. That's science-based 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...

Tri-MG Infusion™ - This anabolic blend consists of clinically studied betaine (a.k.a. trimethylglycine) 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.

Who Should Take Amplified Mass XXX™?
Amplified Mass XXX™ can help any athlete trying to gain mass or put on added pounds.

When Should I Take It?
For maximum results, Amplified Mass XXX™ should be taken daily. On training days, the product should be consumed immediately after exercise. On non-training days, the product should be taken first thing in the morning or between meals.

‡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 Amplified 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.

I started taking it back in 2010. Intense workouts and got major results. Gained muscle and mass where I wanted. Found it worked better with milk. Was also cycling off and on P6 so when my ex-wife seen me for first time in almost a yr she swore I was taking steroids. That's how solid I got!

Best mass gainers
I have been using this for a while and it is truly helpful. Drink immediately after workout.

Great product
So I have tried several different protein products which hardly helped in gaining muscle mass... This one I take 4 days a week right after a workout and have managed to put on about 25 pounds of muscle in about 4 months (155 to 180). It should be noted, that this is the only thing I use other than regular food... No other supplements and still getting great results. It costs a little more than the other proteins I have used, but worth the money. The chocolate actually doesn't taste bad at all either for what it's worth too.

Great product!
If you follow the instructions for dosage the product goes quickly, but I think that can be said for most, if not all, mass gainers. Stock up when the prices is low if you can.

Solid Gainer Product
I had great results with this product. I am 24 and have always been skinny and had trouble gaining weight. I hadn't worked out in probably 2 years and I gained about 6 lbs in 2 weeks when i was on the shakes. That seems to be the average gain. I was never sore after my workouts. I also felt more energetic. One issue i did have was that my knees seemed to get joint pain while i was on it. I think that was more due to my diet however. Bottom line is the product works.
