Ingredients

88

GNC AMP Mass XXX boasts a comprehensive ingredient profile aimed at supporting muscle growth and recovery. The key protein components include Whey Protein Concentrate, Calcium Caseinate, and Soy Protein Isolate. This blend offers a mix of fast and slow-digesting proteins, which is crucial for both immediate post-workout recovery and sustained muscle protein synthesis. Whey Protein Concentrate is rapidly absorbed, making it ideal for quick recovery, while Calcium Caseinate provides a slower release of amino acids, supporting muscle maintenance over time. Soy Protein Isolate adds a complete amino acid profile, enhancing overall muscle repair.

Maltodextrin is the primary carbohydrate source, providing a substantial 130 grams per serving. This high carbohydrate content fuels intense workouts and aids in glycogen replenishment, essential for recovery and energy maintenance. Medium Chain Triglycerides (MCTs) offer a quick energy source, and Polydextrose adds fiber, promoting digestive health.

The product also includes Tri-MG Infusion™, which contains Betaine Anhydrous and HMB (as Calcium HMB), compounds known for their roles in muscle maintenance and recovery by reducing muscle protein breakdown and enhancing repair. Additionally, the Creatine Matrix Blend (DiCreatine Malate, Creatine Ethyl Ester HCL, Guanidinoacetate, Creatine AKG, L-Arginine, L-Glycine, L-Methionine) is noteworthy for its strength and power-boosting properties.

Micronized amino acids such as L-glutamine, L-arginine, and L-leucine are included for better absorption, ensuring effective nutrient delivery to muscles. However, the presence of artificial flavors and sweeteners like Acesulfame Potassium and Sucralose may be a drawback for those seeking natural products. That said, there really aren't options for mass gainers that don't include some artificial ingredients.

Overall, the ingredient quality and thoughtfully curated blend make GNC AMP Mass XXX a compelling choice for muscle building, despite the inclusion of artificial additives.

Effectiveness

93

GNC AMP Mass XXX excels in its primary purpose of supporting muscle gain and recovery. The product's protein blend, delivering 50 grams of protein per serving, includes a mix of fast and slow-digesting proteins. Whey Protein Concentrate ensures rapid amino acid delivery post-workout, while Calcium Caseinate sustains protein synthesis over several hours, providing a continuous supply of nutrients to muscles. Soy Protein Isolate further enriches the protein profile with its complete amino acid content, aiding in overall muscle repair and growth. Soy is actually quite high in naturally occurring BCAAs as well as arginine which enhances blood flow to muscles.

Digestion

The high carbohydrate content, at 130 grams per serving primarily sourced from Maltodextrin, is particularly effective for those in bulking phases or undergoing rigorous training sessions. These carbs help replenish glycogen stores, maintain energy levels, and promote recovery, making the product ideal for intense workouts.

A standout feature is the Creatine Matrix Blend, which includes multiple forms of creatine such as DiCreatine Malate and Creatine Ethyl Ester HCL. Creatine is extensively researched and proven to enhance strength, power output, and overall athletic performance. The blend also includes essential amino acids like L-arginine and L-glycine, which play vital roles in muscle growth and repair.

The inclusion of Tri-MG Infusion™ with Betaine Anhydrous and HMB supports muscle maintenance and accelerates recovery by reducing muscle protein breakdown. Micronized amino acids such as L-glutamine and L-leucine ensure optimal absorption and utilization, further supporting muscle growth and recovery.

GNC AMP Mass XXX's high-calorie content, delivering 800 calories per serving, makes it highly effective for those aiming to gain mass rapidly. This caloric density, combined with its comprehensive nutrient profile, supports significant muscle growth and recovery, making it a potent tool for achieving bulking goals.

Taste

87

The Cookies & Cream taste is rich and smooth, not overly sweet. Compared to other mass gainers, this one is flavorful without being overpowering.

When it comes to texture, this protein powder does a decent job. Mixed with water, it dissolves relatively well, though with a slight graininess if not thoroughly shaken. Using a blender seems to solve this minor issue. With milk, the texture improves significantly, becoming creamier. The added creaminess from the milk complements the Cookies & Cream flavor perfectly.

Mixability is another strong point for this product. It blends smoothly with both water and milk, although for a mass gainer, you will probably want to use milk anyway unless you're on the go. There’s minimal clumping, and it only takes a few good shakes to get a consistent mix.

Value

91

GNC AMP Mass XXX positions itself as a medium to premium mass gainer, and this is evident in both its ingredient profile and pricing. At first glance, the inclusion of high-quality proteins such as Whey Protein Concentrate, Calcium Caseinate, and Soy Protein Isolate, along with a comprehensive creatine blend and micronized amino acids, justifies its higher price point. These ingredients are well-regarded for their effectiveness in promoting muscle growth and recovery, making the product a solid choice for serious athletes and bodybuilders.

Relative Cost
$
$

However, when comparing it to other mass gainers in the market, it's clear that while GNC AMP Mass XXX offers a robust nutritional profile, its cost can be a significant factor. Other mass gainers might offer similar macronutrient ratios at a lower price, but they often compromise on ingredient quality or omit beneficial extras like creatine and HMB. This product’s blend of premium ingredients, including creatine and essential amino acids, supports its premium pricing by providing added value through enhanced muscle recovery and performance.

Additionally, the high carbohydrate content, primarily sourced from Maltodextrin, is effective for bulking but might not appeal to those looking for a cleaner carb source. The product’s calorie density is excellent for those aiming to gain weight, but it might not be as appealing for someone on a tighter budget or looking for a more economical option.

Considering the overall ingredient quality and the targeted effectiveness of GNC AMP Mass XXX, it delivers value for those dedicated to muscle gain and recovery. Its comprehensive formulation supports its higher price, making it a worthwhile investment for those who prioritize ingredient quality and targeted results over cost alone.

Conclusion

90

GNC AMP Mass XXX is a robust mass gainer designed to support serious muscle growth and recovery. Its blend of fast and slow-digesting proteins, combined with a comprehensive array of performance-enhancing ingredients like creatine and HMB, sets it apart from many competitors. The high calorie and carbohydrate content makes it particularly effective for bulking phases. This product is well-suited for athletes and bodybuilders who prioritize quality and comprehensive nutritional support over cost considerations. For those looking for a high-quality mass gainer that delivers on its promises, GNC AMP Mass XXX is a solid choice.
