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.
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 complement your training - you won't achieve maximal gains. The foundation of 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 milk. That's science-based nutrition for Advanced Muscle Performance.
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.
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.

Itâ??s a great boost in calorie intake, but Iâ??m not a huge fan of the vanilla. Also i wish there were more servings per container.

So I work out finish work out and take a serving quick then make me another serving take it more calmly is that a good way?
A shopper on Mar 20, 2018
BEST ANSWER: I take some or ear before lifting and then have a full serving within 30 minutes of my workout ending.

The chocolate is the best tasting shake Ive had yet (and Ive had a lot).
