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.

Pricy but works
This product is pricey but it works. Instead of taking the full serving I took half of the required serving to make it last longer. And I would just add a banana or take with 2 spoons of peanut butter. After taking this product I gained 11 lbs.

Perfect for mass gain
I am an underweight individual who was looking to gain some size with the focus being increased muscle mass. I drink this every morning (2 to 3 scoops) and after my workout (2 to 3 scoops) and eat moderately sized portions for each meal. This use requires lots of calories to be burnt each day, as this is a high calorie product. This is highly recommended for those looking to gain weight. Be careful, however. You can easily gain weight that is fat if you use too much and don't work out enough. I've added about 15 lbs in a month and a half. One thing of note, you will notice muscle tone much faster using this, as opposed to eating "normal" everyday foods. This product is made to gain muscle. Once enough weight is added, you might consider dropping down to a lower calorie protein drink. One other thing worth noting, you will definitely notice increased energy and endurance. Since I've been using this product, I am literally never tired. I work 12 hour days, workout 1 hr each day, and get about 6 hrs of sleep each day, yet am always going strong.

First off i would like to say i am a semi pro football player who plays rb/S and i took this product to gain weight.I took 2 scoops in the morning after my workout or before work and another 2 scoops before i went to bed also along with it i took a scoop of pure protien hplc creatine and this stack put on over 5 pounds in 2 weeks. This product was awsome i recomend it to anyone who has trouble gaining weight like myself. When taken with milk it is a good source of extra protien and calories. i will buy this product again and tell all my friends to use it!!!! BUY THIS PRODUCT!!!

Great Gains
I took this product after every workout. I never crashed and the results say it all. Two weeks in and already gained 5 pounds of muscle. I did notice small break out reactions to product but I thought nothing of it. Best part of all you feel great after you work out. I am able to work out two times a day. Once in the morning and an even harder work out in the afternoon and never feel sore. Definintly worth the money, especially if your a gold card number along with the buy one get one half off deals.

Repeat buyer of this.
I took this at 2 scoops daily after workout or in the morning on non-workout days. The first container I went from 168 to 175. Diet was/is good, and took multi. Workout heavily. Second tub is strawberry, which isn't a personal favorite but caught it on sale. Tastes good as well.

This is my favorite supplement from GNC so far! I used to use muscle milk, but this is better! I paid [$] or less for it so it was a GREAT deal for me, but to lay down [$] for it, I think i'll wait for it to be cheaper. It tastes great and definetely does shorten the recovery time. I noticed that if I take it before a workout that I was lifting more but I prefer to take it after. One of the side effects on me was that it gave me an outbreak of acne.. It says take 4 scoops, but I take 1 and a half to 2 the most. It does have some creatine in it so you would be best off drinking plenty of water. I definetely gained a few solid pounds while using it (I only used it for 2 weeks so far). I'm 5'11" and weigh 160 pounds of muscle. I am also a swimmer so it is faily difficult for me to gain weight but I have with this. If you're looking for something that works, definetely give this one a try!

Best flavor I've ever had
It tastes just like banana pudding. It recommends taking 4 scoops to every 16 oz of water, but I get too bloated. 2 scoops to every 16 oz of SKIM MILK, plus a scoop & half of cookies & cream makes this tastes just a liquid banana pudding, & its not an overpowering flavor. If you like banana flavored anything, this is a MUST BUY!

Tastes good and results are good for me.
I have a fast metabolism so I am a hard gainer. For years people told me I could not gain and I thought it was true. I tried different proteins and they seemed to leave me feeling bloated and did nothing. I tried this one and workout three times a week and have noticed great gains. Before people told my I looked sick and now when they see me they say wow you look great. I wrote this review for people that are in a similar situation as I was so you can know if you stick to this you will gain but you have to also be consistent with your workouts. The tastes is good and the results are excellent for me. I recommend this protein.

[$] for 13 servings?????? really gnc, if you just buy any whey protein blend with the average 24 grams of protein per scoop you get close to 100 grams of protein with 4 scoops and this stuff takes 4 scoops just to get 50 grams. its amazing that gnc is able to get people to buy this stuff, i mean does anyone consider amount per serving when they buy this average stuff. if im paying [$] for protein it needs to have at least 65 serving and thats still a little expensive for that amount.
