GNC Pro Performance AMP Amplified Mass XXX Chocolate Review
GNC Pro Performance AMP Amplified Mass XXX in Chocolate is a high-calorie, high-protein weight-gainer powder. GNC sells it as exclusive to its stores, and it is built to increase lean mass, body weight, strength and stamina. Newer packaging calls it "AMP Mass XXX with MyoTor." It is mixed into a shake and taken as a calorie and protein supplement alongside resistance training. The Walmart listing for the Strawberry version of the same line gives about 780 calories and 50 g of protein per serving, with 13 servings per tub. I did not confirm the exact Chocolate panel, so check the label on your tub. How it works: 1. **Calorie surplus.** Muscle gain needs more energy than you burn. Each serving supplies a large amount of calories, made up of protein and carbohydrate. This makes it easier to eat in surplus than whole food alone, which helps people who struggle to gain weight. 2. **Protein and amino acids.** The formula is a protein blend with micronized amino acids. An Indian retailer's page says these are broken into smaller particles for quick absorption. It lists glutamine, leucine and arginine among the key amino acids. Leucine is the main amino acid that switches on muscle protein synthesis through the mTOR pathway. Delivering amino acids after training supports repair and growth. 3. **Creatine and betaine.** The Walmart title lists creatine and betaine. Creatine raises phosphocreatine stores in muscle, which supports short bursts of high-intensity effort and lets you do more work per session. Betaine is studied for its role in power output and in cell hydration and methylation. 4. **Clinical backing.** GNC's product page cites an eight-week study. In it, subjects on the supplement gained body weight, fat-free mass, maximal muscle strength and muscle endurance equal to a control group. The supplement group did only 3 sets of resistance training per day, compared with 5 for the control group. This is the company's own claim, and I did not review the study itself. 5. **Quality assurance.** The Indian retailer page says products with the banned-substance-tested logo have been tested for banned substances. This is a quality signal, not a performance mechanism. The product is a food-based supplement and not a drug. Results depend on training, total diet and sleep. The weight gained will include some water, especially from creatine, along with muscle and possibly fat if the surplus is too large. People who are sensitive to dairy, or who have kidney conditions, should check the label or ask a clinician before using it.

Members Only68 human studies · 27 improved
This shake gives 50 grams of protein per serving, well above the 15 grams that worked in studies. Large pooled analyses support protein for building muscle, mainly alongside strength training. Across 49 trials in healthy adults lifting for at least 6 weeks, protein supplements increased strength, lean mass and muscle size, with no extra lean mass gain beyond about 1.6 grams per kilogram of body weight per day [1]. Across 78 trials in middle-aged and older adults doing strength training, whey gave the largest gains in muscle mass, grip strength and walking speed [2]. Another analysis of 65 trials found about half a kilogram more lean mass, without clear strength gains [3], and a review of 74 trials found small gains in lean mass and lower body strength with training [4]. In older adults with muscle loss, whey increased muscle mass and walking speed [5]. Protein alone, without training, did not improve muscle size or strength over one year in older adults, while training plus whey did [6]. The listing also names creatine, MyoTOR and BETAPOWER, but the label gives no amounts for them and no study findings for them were provided, so they are not graded here. Animal and cell studies are never counted.

Review Totals and Summary
Members Only438 reviews · 100% positive
Customers mostly say the product delivers on weight and strength. Reviewers on GNC's page describe quick, noticeable size gains. One says their arms "got big fast" after a single tub. A parent bought it for a football-playing son who needed to add weight for college ball. Long-term users say it works well and is reasonably priced. Others say they felt and saw a difference in size and performance before finishing the first tub, and one had bought about eight tubs. A Walmart reviewer says they gained strength and bigger lifts, and that they would use it again to rebuild mass after a break. Taste is where opinions split, and the split depends on the flavor. Chocolate is the best-liked flavor. One reviewer calls it the best-tasting shake they have had, and another says it tastes like melted Hershey bars. Not everyone agrees. One Walmart reviewer describes a combination of chocolate, chalk and medicine flavor. Other reviewers call vanilla "weird," and one says vanilla and cookies and cream are the worst flavors they have tried. Strawberry gets praise from some buyers. The other recurring points concern who the product suits. Reviewers describe it as a mass builder for lean or "hard gainer" types. At least one overweight, older user reports gains too. Several reviews were collected through promotions or posted on GNC's own site, so they probably skew positive. Ratings vary by retailer. GNC's page shows a very high score from a small number of reviews, and Walmart shows a lower score. Walmart's reviews are more mixed, mainly on taste. Retail pages show little discussion of side effects, digestion or mixing quality in the sample I read, so those themes are less well covered.

Body systems: Muscular system, Digestive system
Combine with: For muscle building, pair it with creatine monohydrate (3-5 g daily) for strength and lean mass, along with beta-alanine or citrulline malate for training performance and endurance. Add a quality multivitamin and vitamin D3 with K2 for general and bone support, plus omega-3 fish oil (EPA/DHA) to support recovery and cardiovascular health. If blood pressure is a concern, consider discussing magnesium, potassium-rich foods, CoQ10, or beet root nitrate with a healthcare provider, and keep in mind that mass gainers are high in sugar and calories. Use them in moderation, and make sure your diet and exercise habits support heart health.
Possible side effects: No major side effects reported. Some reviewers dislike the taste, describing a chalky or medicine-like flavor.
