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.

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.

does what it says
This supplement helped me gain lean mass in all the right places!
June 10, 2015
so tasty
You can never find quality product that gives you what you need in your workout but also taste very good!
April 26, 2015
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.

Great product

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.

I'm doing a weightlifting routine because I want to gain muscle but I also need to lose some pounds of belly fat, if I use this product would delay my goal of burning my extra fat?
A shopper on Jun 27, 2012
BEST ANSWER: There are 750 calories in one serving and the main purpose is to add pounds of muscle--I'm thinking you would not be able to burn fat very well on a diet with an extra 750 calories a day.

BEST ANSWER: Im 13 and i take it and ive seen massive gains
Is there any age limit for this product? For example, can you 4 year old son or an 70 year old grandpa take it?
A shopper on Apr 29, 2012
BEST ANSWER: Keep anyone under 17 away from it. the label says consult a physician if under 18 but basically, its all based on how much you've grown. the creatine in this product can change the way your muscles develop if you arent completely grown. but all the way up until you dont really need it anymore at that point.
i just bought this product got home from the gym, directions say take for level scoops but it fill up atleast half of my shaker. is this correct?
A shopper on Jan 16, 2011

I am 16 years old and I'm 6'3, weighing 145 pound I want to start gaining muscle and weight. What product do you recommend?
A shopper on Feb 5, 2014
BEST ANSWER: i would say use the one that has the best reviews personally, but you have to be consistent in the gym to get the results you want, its not going to come easy and that's where some people tend to fail, but its good that you have your weight already taken down cause that's going to play a big part. Me personally i cant really stand any other flavors, so i use chocolate everything. so what i do is, drink a bottle of chocolate milk, then take my protein, and do that prior and after my work out, but keep in mind certain things don't work for everybody, you might have to change up things a little, to fit your needs. i hope things work out for you
is it necessary that you have to take 4 scope every single day, even though i skip one day?
another question- what if i take 2 scope and workout for 1.5 hours? do u think i will gain weight?
A shopper on Jan 15, 2014
BEST ANSWER: In order for it to work you need to take the recommended dose, even though you miss a day continue on as should be taken.
I am currently taking (GNC Pro Performance® AMP Amplified Wheybolic Extreme 60™ Platinum Edition ), I am 5ft9 I lost 35 lbs and now I weigh 152lbs. I want to now build some muscle, preferably approximately 10lbs max. I'm trying to see if I need to switch to a mass gainer like this because I haven't seen any real results in gaining muscle. I know diet is a big part and for more muscle I need to consume more calories, protein, carbs etc. And I wonder if this over the platinum would help better. But not really sure. Right now on workout days I take 3 scoops of the platinum post workout.

Thank You

Hi, I use GNC Pro Performance AMP Amplified Wheybolic Extreme 60™ Vanilla 30 minutes after workout and GNC Pro Performance® 100% Casein Protein before night. I have a problem, that I am still losing weight. Is this good option for me? I usually train 3 days + 1 free day. And could I use this gainer and also any of these proteins? Thanks a lot!
A shopper on Oct 22, 2013
