Maximum Human Performance UYM XXXL 1350 Weight Gainer - High-Calorie

In this review of Maximum Human Performance UYM XXXL 1350, the bottom line is simple: this is a targeted weight gainer for lifters and hard gainers who need a dense, high-calorie shake to add mass quickly. The reviewer found the product delivers on its core promise of calories and protein per serving, making it a sensible choice for those who struggle to eat enough or want a reliable post-workout mass builder. If the goal is to maximize muscle growth with a single serving product that combines fast and slow proteins, this weight gainer deserves close consideration.

Key Features

• 1350 Nutrient Dense Calories: Each serving supplies a very high calorie load intended to support rapid weight and muscle gain when combined with heavy training and a surplus diet.
• 50g Protein Blend: The multi-phase protein matrix of whey concentrate, isolate, hydrolyzed whey, micellar casein and milk protein delivers both fast amino delivery and sustained nitrogen retention for recovery and growth.
• Mass Load Complex Carbs: 250 grams of complex carbohydrate sources such as maltodextrin, sweet potato, oat fiber and quinoa provide a steady supply of glucose to refill glycogen and support caloric needs.
• Functional Fats Included: MCTs, EFAs and CLA are present to add caloric density and support overall macronutrient balance without relying solely on sugars.
• Insulin Optimization: The formulation is designed to support an insulin response that can shuttle nutrients into muscle, which can be useful for post-workout recovery and mass gain phases.
• Milkshake Tasting Flavor: The French Vanilla Creme aims for a dessert-like shake experience, though sweetness perception varies among users.

Who It's For

This product is best for dedicated trainees, natural hard gainers and athletes who need a concentrated, convenient way to hit a large daily calorie and protein target without preparing multiple meals. It suits people following aggressive mass programs or bulking phases who pair the shake with resistance training.

Those who should look elsewhere include casual exercisers who do not need a large calorie surplus, people watching sugar or calorie intake for health reasons, and anyone sensitive to very sweet meal replacements since flavor and mix preference can be polarizing.

Pros & Cons

Pros

• Very high calorie content per serving simplifies meeting a daily surplus for mass gain.

Our Verdict

For committed lifters and hard gainers who need a practical, single-serving solution to reach a large calorie and protein target, this weight gainer is a strong option because of its 1350 calorie density and versatile protein blend. It represents good value for those who will use it consistently during a bulking phase, but flavor sensitivity and the sheer volume of calories mean it is not a one-size-fits-all supplement.
