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.

3 SETS + AMPLIFIED MASS XXX™ = 5 SETS

Health Notes

Soy

Soy
This nutrient has been used in connection with the following health goals
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

High Cholesterol
Dose: 25 grams soy protein per day
Soy supplementation has been shown to lower cholesterol. Soy contains isoflavones, which are believed to be soy's main cholesterol-lowering ingredients.(more)
Hypertension
Dose: 10 grams soy protein or 16 ounces soy milk twice per day
Supplementing with soy protein may significantly lower blood pressure.(more)
Premenstrual Syndrome
Dose: Refer to label instructions
Supplementing with soy protein may help relieve premenstrual swelling and cramping.(more)
Menopause
Dose: Refer to label instructions
Some research has found soy isoflavones may help reduce certain menopause symptoms, such as hot flashes, and support mood and thinking performance.(more)
Obesity
Dose: Refer to label instructions
Soy appears to have several effects on the body that might help with weight loss.(more)
Menopause
Dose: Refer to label instructions
Some research has found soy isoflavones may help reduce certain menopause symptoms, such as hot flashes, and support mood and thinking performance.(more)
Premenstrual Syndrome
Dose: Refer to label instructions
Supplementing with soy protein may help relieve premenstrual swelling and cramping.(more)
Athletic Performance and Exercise Recovery
Dose: 33 to 40 grams daily
In one study, elderly men participating in a strength training program who took a supplement containing protein (part of which was soy protein) immediately following exercise saw significant gains in muscle growth and lean body mass.(more)
High Cholesterol
Dose: 25 grams soy protein per day

Soy supplementation has been shown to lower cholesterol in humans.1 Soy is available in foods such as tofu, miso, and tempeh and as a supplemental protein powder. Soy contains isoflavones, naturally occurring plant components that are believed to be soy's main cholesterol-lowering ingredients. A controlled trial showed that soy preparations containing high amounts of isoflavones effectively lowered total cholesterol and LDL ("bad") cholesterol, whereas low-isoflavone preparations (less than 27 mg per day) did not.2 However, supplementation with either soy3 or non-soy isoflavones (from red clover)4 in pill form failed to reduce cholesterol levels in a group of healthy volunteers, suggesting that isoflavone may not be responsible for the cholesterol-lowering effects of soy. Further trials of isoflavone supplements in people with elevated cholesterol, are needed to resolve these conflicting results. In a study of people with high cholesterol levels, a soy preparation that contained soy protein, soy fiber, and soy phospholipids lowered cholesterol levels more effectively than isolated soy protein.5

Hypertension
Dose: 10 grams soy protein or 16 ounces soy milk twice per day

In a double-blind study of postmenopausal women, supplementing with 10 grams of soy protein twice a day for six weeks significantly reduced diastolic blood pressure by an average of 5 mm Hg, compared with a diet not containing soy protein.1 In another study, men and women with mild to moderate hypertension consumed 500 ml (approximately 16 ounces) of soy milk or cow's milk twice a day for three months. After three months, the average systolic blood pressure had decreased by 18.4 mm Hg in the soy group, compared with 1.4 mm Hg in the cow's milk group. The reductions in diastolic blood pressure were 15.9 mm Hg with soy milk and 3.7 mm Hg with cow's milk.2 In another study of people with hypertension who were consuming a low-protein, low-fiber diet, supplementing with a combination of soy protein and psyllium (a fiber source) lowered systolic blood pressure by an average of 5.9 mm Hg.3 The blood pressure reduction with soy protein alone or with fiber alone was less pronounced than that with combination treatment. Other research has also shown a blood pressure-lowering effect of soy protein.4, 5

Premenstrual Syndrome
Dose: Refer to label instructions

In a double-blind trial, supplementing with soy protein (providing 68 mg of isoflavones per day) for two menstrual cycles was significantly more effective than a placebo at relieving premenstrual swelling and cramping.1 The placebo used in this study was cow's milk protein. Some doctors believe that cow's milk, because of its estrogen content, can worsen premenstrual symptoms. If that is the case, then the beneficial effect of soy protein may have been overestimated in this study.

Menopause
Dose: Refer to label instructions

A double-blind study of 78 postmenopausal women (average age, 49.5 years) were randomly assigned to receive 60 mg per day of soy isoflavones (as aglycone) or placebo for six months.1 Then after a one-month break, each woman received the alternate treatment for an additional six months. Thinking (cognitive) performance and mood were assessed by tests at the end of each treatment period. Compared with placebo, people treated with isoflavones experienced significant improvement on 6 of 17 measures of cognitive function and 7 of 8 measures of mood. In another double-blind study, 177 postmenopausal women (average age, 55 years) who were experiencing five or more hot flushes per day were randomly assigned to receive soy isoflavones (50 mg per day total of an approximately equal mixture of isoflavones genistin and daidzin) or placebo for 12 weeks.2 The average reduction in hot flash frequency after 6 weeks was significantly greater in the isoflavone group than in the placebo group; however, during the entire 12 weeks, the difference between the two groups was only marginally significant.

Obesity
Dose: Refer to label instructionsAnimal and human studies have suggested that when soy is used as a source of dietary protein, it may have several biological effects on the body that might help with weight loss.1 A preliminary study found that people trying to lose weight using a meal-replacement formula containing soy protein lost more weight than a group not using any formula.2 However, controlled studies comparing soy protein with other protein sources in weight-loss diets have not found any advantage of soy.3, 4, 5 When soy protein is used for other health benefits, typical daily intake is 20 grams per day or more.

Athletic Performance and Exercise Recovery
Dose: 33 to 40 grams daily

In one preliminary study, elderly men participating in a 12-week strength training program took a liquid supplement containing 10 grams of protein (part of which was soy protein), 7 grams of carbohydrate, and 3 grams of fat either immediately following exercise or two hours later.1 Men taking the supplement immediately following exercise experienced significantly greater gains in muscle growth and lean body mass than those supplementing two hours later, but strength gains were no different between the two groups. A controlled study of female gymnasts found that adding 0.45 grams of soy protein (0.45 grams per pound of body weight per day) to a diet that was adequate in protein during a four-month training program did not improve lean body mass compared with a placebo.2 No research has compared different sources of protein to see whether one source, such as soy protein, has a better or more consistent effect on exercise recovery or the results of strength training.
