Mutant Mass is engineered specifically for athletes and trainers who struggle to consume enough daily energy from whole foods alone. It provides an exceptionally dense, high-calorie nutritional profile designed to deliver 1,100 clean calories per full serving when mixed with water (and significantly higher when mixed with milk). This concentrated calorie load provides the essential structural energy fuel required to support heavy resistance training, muscle conditioning, and rapid physical scaling. 

To support continuous tissue conditioning and prevent nutrient drop-offs, Mutant Mass features a premium, multi-stage complete protein blend. It dynamically combines rapid-absorbing and sustained-release protein sources, including Whey Protein Concentrate, Hydrolyzed Whey Protein, Whey Protein Isolate, Micellar Casein, Milk Protein Concentrate, and Milk Protein Isolate. This matrix delivers a massive 56g of complete protein per full serving, providing a steady, long-lasting wave of essential amino acids to muscle tissues. 

Unlike basic weight gainers that rely almost entirely on cheap, highly processed sugars, Mutant Mass utilizes a premium real-food carbohydrate architecture. It features a 192g clean carb blend sourced from nutrient-dense, low-glycemic whole foods including Waxy Maize Corn Starch, Barley Starch, Sweet Potato, and Rolled Oats. This food-based system delivers a massive wave of clean glycogen replenishment to fuel intensive workouts without causing the severe energy crashes or digestive heaviness associated with high-sugar alternatives. 

Not all fats are equal, and Mutant Mass completely avoids cheap hydrogenated oils or processed trans fats. Instead, it incorporates a specialized food-based lipid blend containing Coconut MCT Oil (Medium-Chain Triglycerides), Avocado, Flaxseed, Pumpkin Seed, and Sunflower Oils. These premium essential fatty acids (EFAs) provide a clean, slow-burning source of structural energy that supports cellular health, metabolic efficiency, and joint conditioning during heavy lifting cycles. 

Every full serving is loaded with high-density, naturally occurring recovery building blocks:

Essential Amino Acids (EAAs): 26.1g of complete EAAs to drive comprehensive nutrient uptake.

Branched-Chain Amino Acids (BCAAs): 12.2g of BCAAs (including a high concentration of L-Leucine) to directly signal muscle protein synthesis.

Glutamine: 10.4g of naturally occurring Glutamine and Glutamic Acid to optimize cellular hydration and post-workout muscle repair.

A standard full-strength serving consists of 4 scoops (280g total). Sprint Fit stocks multiple sizes to fit your specific macro timeline:

2.27kg (5LB) Bag: Provides 8 full servings (or 16 half-strength servings, making it a great introductory option).

6.8kg (15LB) Bulk Bag: Provides a massive 26 full servings (or 52 half-strength servings, offering the absolute best long-term value per scoop to keep your pantry fully stocked).

The Full-Strength Method: Shake or blend 4 scoops (280g) with 480–960ml of cold water or milk. This is ideal taken immediately post-workout or split into two independent 2-scoop servings throughout the day.

The New User Method: If you are new to high-calorie gainers, start with a half serving (2 scoops) twice daily between main meals. This allows your digestive system to smoothly adapt to the increased nutrient volume.

Liquid Choice: Mixing with chilled water keeps the texture clean and light, while mixing with full-cream milk adds an extra 150–300 calories and creates a rich, gourmet milkshake consistency.
