For years, I’ve listened to the same refrain from countless athletes and clients: “I eat all the time, I train like a beast, but the scale just won’t move.” It’s the classic hardgainer’s lament, a frustrating cycle of dedication met with stagnation. I’ve been there myself—a period in my early training days where, despite a seemingly bottomless appetite and a religious adherence to my lifting schedule, I couldn’t add a single pound of quality mass. This isn’t just a blow to the ego; it’s a genuine physiological roadblock. Without a significant caloric surplus, the body simply lacks the raw materials needed for muscle protein synthesis and recovery. Failing to overcome this barrier means wasted effort in the gym, suboptimal recovery, and the very real risk of burnout. It’s in this struggle for surplus calories and quality nutrients that a specialized tool becomes not just a convenience, but a necessity. This is where products like the Maximum Human Performance MHP UYM XXXL 1350 Mass Gainer enter the conversation.
- ✓ 1350 Nutrient Dense Calories
- ✓ Powerful Gains in Hard, Dense Muscle Mass
- ✓ Optimizes Insulin Response for Maximum Muscle Growth
What to Consider Before Buying a Mass Gainer
A Sports Nutrition Weight Gainer is more than just a protein shake; it’s a key solution for anyone who finds it physically impossible or impractical to consume the sheer volume of whole food required to gain weight and build muscle. These products solve the fundamental problem of achieving a consistent and significant caloric surplus. By concentrating protein, complex carbohydrates, and essential fats into a drinkable, easily digestible format, they provide the anabolic fuel necessary for growth without forcing you to sit down for another full meal. The main benefits are efficiency, convenience, and the targeted delivery of macronutrients specifically formulated to support muscle repair and hypertrophy. For hardgainers, athletes with demanding schedules, or individuals recovering from significant weight loss, a mass gainer can be the critical difference-maker.
The ideal customer for this type of product is someone facing a high metabolic rate, a small appetite, or a time-crunched lifestyle that prevents them from preparing and eating 4-6 large meals a day. They are serious about their training and understand that nutrition is the other half of the battle. Conversely, a mass gainer might not be suitable for those who are naturally endomorphic (gain weight easily), are primarily focused on fat loss, or can comfortably meet their caloric needs through whole foods alone. For these individuals, a standard whey protein isolate or a whole-food meal replacement might be a more appropriate choice. It’s crucial to match the tool to the specific goal.
Before investing, consider these crucial points in detail:
- Container Size & Servings: Mass gainers are dense, so the tubs are often large. Consider the physical dimensions (this MHP tub is approximately 8x8x11 inches) and where you’ll store it. More importantly, look at the servings per container. The Maximum Human Performance MHP UYM XXXL 1350 Mass Gainer comes in a 6lb tub with 8 servings. This is a crucial metric for calculating cost-effectiveness and planning your supplement cycle. A higher serving count may offer better long-term value.
- Caloric and Macronutrient Profile: This is the heart of the product. At 1350 calories per serving, this is a heavy-hitter designed for serious gains. You must evaluate the protein-to-carb ratio (50g protein to 250g carbs here) and the quality of those sources. Does the profile align with your daily macro targets? If you only need a 500-calorie surplus, you might use a half-serving, which effectively doubles the servings per container and changes the value proposition.
- Ingredient Quality & Source: Look beyond the numbers. This product uses a blend of fast and slow-digesting proteins (whey, casein) and complex carbs from sources like sweet potato and quinoa, not just sugar. For athletes, certifications like the “Informed-Choice Certified” label are non-negotiable, guaranteeing the product is free from banned substances. The presence of functional fats like MCTs and CLA also adds significant value.
- Mixability & Digestibility: A gainer is useless if you can’t stomach it. The texture and thickness can be a major factor, as some user feedback indicates. Consider if you’ll be using a shaker bottle or a powerful blender. Pay attention to ingredients that might cause digestive distress for you, and look for reviews that specifically mention how well the product sits in the stomach, especially when consumed post-workout.
Understanding these factors ensures you select a mass gainer that not only fuels your goals but also fits your lifestyle and digestive system.

First Impressions: Unboxing a Caloric Colossus
The 6lb tub of the Maximum Human Performance MHP UYM XXXL 1350 Mass Gainer has a commanding presence. The MHP branding is bold and aggressive, clearly targeting the serious athlete who wants no-nonsense results. Upon cracking the seal on the Cookies & Cream flavor, the aroma is immediately pleasant—a sweet, creamy scent that’s more dessert-like than medicinal, a promising start. The powder itself is exceptionally fine, a testament to the “Micronparticulated Maltodextrin” listed in its ingredients. This fine texture often suggests better mixability. The included scoop is large, as expected for a serving size that packs a 1350-calorie punch; it’s a visual reminder that you’re dealing with a truly nutrient-dense formula. Compared to some other gainers that can have a gritty, sandy texture, the initial feel of the powder is smooth. My first thought was how this massive serving would mix and, more importantly, how it would sit. The ingredient list reads like a checklist for an ideal mass-building formula, and you can see its full feature set and user reviews to verify the robust profile. It feels substantial and purposefully designed, setting high expectations for performance testing.
Key Benefits

Performance Deep Dive: Deconstructing the MHP Mass Gainer
A mass gainer’s worth is measured in pounds on the scale and inches on the tape measure. To understand if the Maximum Human Performance MHP UYM XXXL 1350 Mass Gainer delivers, we need to go beyond the label and analyze how its formula works in the real world. We broke down our extensive testing into three key areas: its macronutrient engine, the all-important taste and mixability factor, and the recovery-boosting components that separate a good gainer from a great one.
The “XXXL 1350” Macronutrient Engine
The headline feature is, without a doubt, the 1350 calories packed into every serving (when mixed with whole milk, as recommended for maximum gains). This is not just empty calories; it’s a meticulously crafted profile designed for lean mass accretion. The foundation is the 250g of “Mass Load™ Complex Carbs.” During our testing, this blend provided a notable difference in sustained energy compared to gainers that rely solely on maltodextrin or dextrose. The inclusion of sweet potato, oat fiber, and quinoa adds nutritional value and helps modulate the insulin response. A massive insulin spike from pure sugar can be great immediately post-workout, but for a shake that might be consumed at other times of the day, this more complex blend helps prevent a subsequent energy crash. It fuels your body for hours, making it an excellent choice for a meal replacement on a hectic day or to load up before a grueling training session.
The 50g of protein is equally impressive. MHP uses a five-source matrix: Whey Concentrate, Isolate, Hydrolyzed Whey, Micellar Casein, and Milk Protein. This is a critical design choice. The hydrolyzed and isolate whey hit your system almost immediately, kick-starting muscle protein synthesis right after a workout when your muscles are screaming for nutrients. Then, the concentrate, milk protein, and especially the slow-digesting micellar casein take over, providing a “trickle-feed” of amino acids for up to 8 hours. This sustained release profile makes it a uniquely versatile gainer. We found it worked exceptionally well post-workout, but also as a shake before bed to create an anti-catabolic environment while you sleep. The functional fats—MCTs, EFAs, and CLA—are the unsung heroes, supporting hormone production and providing another dense energy source that spares muscle glycogen. This intelligent combination of macros is a feature that really sets it apart in a crowded market.
Taste, Texture, and Digestibility: The Make-or-Break Factors
If you can’t stand drinking it, the best formula in the world is useless. The Cookies & Cream flavor we tested was genuinely delicious. It tastes like a melted milkshake, with small cookie-like bits that add a pleasant texture. It’s sweet, but not cloyingly so, which is important when you’re consuming such a large volume. However, this brings us to a critical point confirmed by user feedback: this shake is thick. Extremely thick. Mixing a full four-scoop serving in a standard shaker cup with the recommended 24 oz of water is a workout in itself. It’s doable, but it results in a consistency closer to pancake batter than a beverage. For optimal results, a blender is highly recommended. Using a blender not only creates a smoother, more palatable shake but also allows you to add other ingredients like a banana or peanut butter to further boost the nutritional value.
This thickness directly relates to digestibility. One user reported that it “hurts my gut so bad,” and we can understand why this might happen. Consuming 1350 calories and over 300 grams of solids in liquid form is a massive task for your digestive system. During our evaluation, we found that the best approach for those with sensitive stomachs, or anyone new to mass gainers, is to start with a half-serving (two scoops). This is still a substantial 675-calorie shake with 25g of protein, making it easier to digest while still providing a significant caloric boost. By gradually increasing to a full serving over a week, we allowed our digestive systems to adapt, which significantly reduced any feelings of bloating or discomfort. It’s a powerful formula, and like any powerful tool, it requires a smart approach.
Recovery and Performance: The Amino Acid Advantage
Beyond the raw calories and macros, the Maximum Human Performance MHP UYM XXXL 1350 Mass Gainer is fortified with key performance nutrients that accelerate recovery. Each serving delivers a staggering 11g of naturally occurring Branched-Chain Amino Acids (BCAAs) and 23g of Essential Amino Acids (EAAs). The BCAAs—Leucine, Isoleucine, and Valine—are particularly crucial for muscle growth. Leucine, in particular, is the primary trigger for muscle protein synthesis (mTOR signaling). Having a high dose of it, especially in the fast-absorbing whey proteins, means you’re flipping the “on” switch for muscle building immediately after your workout. We noticed a tangible decrease in delayed onset muscle soreness (DOMS) when consuming this shake post-workout compared to training days without it. This isn’t just a subjective feeling; it’s the direct result of providing your muscles with the specific building blocks they need to repair and rebuild stronger.
For any serious athlete, what’s *not* in the product is as important as what is. The fact that this gainer is Informed-Choice Certified is a massive vote of confidence. This third-party certification guarantees that every batch is tested for substances banned by the World Anti-Doping Agency (WADA). This provides peace of mind for competitive athletes who undergo regular testing. It demonstrates MHP’s commitment to quality and purity, ensuring that you’re fueling your body with clean, effective nutrients. You can check the latest price and availability and invest in a product that supports both performance and integrity.
What Other Users Are Saying
Our findings are largely echoed by the broader user community, which shows a mix of strong praise and specific critiques. On the positive side, many users highlight the same points we did. One happy customer noted it’s a “Good price for this protein,” adding that it “has a great flavor and comes with a scoop.” This aligns perfectly with our experience of the Cookies & Cream flavor being genuinely enjoyable and the product offering solid value for its potent formula. The comment that “It’s good for your health if you’re going to build muscle mass” speaks to the effectiveness users are seeing in their own results, confirming it delivers on its primary promise.
However, the negative feedback is just as telling and centers on one key issue: texture and digestibility. A particularly blunt review stated, “It was awful it’s extra thick and hurts my gut so bad.” This is the exact issue we identified. The product’s density, while a strength for caloric intake, is a clear weakness for those with sensitive digestive systems or who dislike thick shakes. This feedback is critical because it validates our advice: start with a half-serving and use a blender. For some, the formula may simply be too intense, making it an important consideration before purchase.
How Does It Compare? MHP UYM XXXL 1350 vs. The Competition
The Maximum Human Performance MHP UYM XXXL 1350 Mass Gainer is a formidable contender in the high-calorie space, but it’s not the only option. Depending on your specific dietary philosophy and goals, one of its competitors might be a better fit.

It’s designed to optimize your body’s own muscle-building potential through non-hormonal pathways, using ingredients like organic mushrooms and PeakO2®. With only 30 calories per serving, it’s not meant to provide a caloric surplus. This is an alternative for someone who has their diet dialed in and doesn’t need extra calories but wants an edge in performance, endurance, and recovery. You would choose this if you’re looking to maximize the results from the food you’re already eating, rather than adding more food (or a food substitute) to your diet.
Final Verdict: Is the MHP UYM XXXL 1350 Right for You?
After extensive testing and analysis, our verdict is clear: the Maximum Human Performance MHP UYM XXXL 1350 Mass Gainer is a top-tier weapon in the arsenal of the serious hardgainer.

The taste is excellent, and its Informed-Choice certification offers crucial peace of mind for competitive athletes.
Its primary weakness—the extreme thickness and potential for digestive upset—is a direct consequence of its strength. This is not a casual protein shake; it is a dense, powerful nutritional tool. We strongly recommend it for individuals who have historically struggled to gain weight and who are prepared to manage its richness by starting with smaller servings and using a blender. If you are a true ectomorph or an athlete with immense caloric needs, this product is built for you. It delivers on its promise of providing the massive, high-quality caloric surplus needed to finally see the scale move in the right direction. If you’re ready to break through your plateau and fuel serious growth, we highly recommend you give the Maximum Human Performance MHP UYM XXXL 1350 Mass Gainer a try.
