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.

Great product
My husband has been using this for about 2 months now and it has given him tremendous energy to get through his busy working day. After being off work for 6 months and total knee replacement he is feeling great now that he has been using this product. He just had an annual exam today and the doctor said he is very healthy. Yay

Is this the same as your old product 'amplified mass xxx'?
judy d on Jun 5, 2018
BEST ANSWER: The woman at GNC said it was the same, but Rite Aid still has the original black and red container of Amplified Mass XXX........... The outside of the new container is different, the scoop doesn't even remotely resemble the other scooper and the directions for use are different. It tastes the same. I just purchased the new container so I'm guessing it's the same with 50 grams of protein per serving. Will soon know.
how was the taste?
