Mutant Mass Protein Powder – Smart Carb Mass Gainer Formula

Mutant Mass Protein Powder is a high-calorie mass gainer designed for people who struggle to eat enough to support muscle growth and weight gain. Each 3-scoop serving delivers 535 calories, 29g of protein, and nearly 99g of carbohydrates from a premium whey protein matrix and Smart Carb Blend. It provides a convenient way to increase daily calorie intake without forcing extra meals.

 

Key Benefits

  •  High-calorie formula for weight and muscle gain – Each shake delivers 535 calories to help increase total daily calorie intake, making it easier to support size and strength goals.
  •  29g protein from a multi-source whey protein matrix – Includes whey protein concentrate, hydrolyzed whey, and whey protein isolate to deliver a complete amino acid profile with both fast and sustained protein absorption.
  •  Smart Carb Blend for steady energy – Combines maltodextrin with SusCarb (Highly Branched Cyclic Dextrin) to provide high carbohydrate energy with a more gradual delivery compared with maltodextrin alone.
  •  Supports digestion and nutrient absorption – Includes POOLZYME digestive enzyme complex to assist the breakdown of protein, carbohydrates, and fats in each high-calorie shake.
  •  Supports muscle protein synthesis – Provides essential amino acids including 6g leucine, 3.3g isoleucine, and 2.9g valine (BCAAs) to support muscle protein synthesis and recovery.
  •  Convenient calorie boost between meals – Easy to mix in a shaker or blender, making it practical to add extra calories throughout the day.

 

High-Calorie Nutrition for Hard Gainers

Mutant Mass is designed for athletes and gym-goers who need more calories than they can easily get from food alone. The combination of a whey protein matrix and high-carbohydrate Smart Carb Blend helps support calorie intake for weight gain and training recovery. With 16 servings per 5 lb bag, it provides a practical option for increasing daily nutrition during intense training phases.

FAQs

How many servings are in a 5 lb bag of Mutant Mass?
Each 5 lb bag provides 16 shakes when using the recommended 3-scoop serving size.

Can I mix Mutant Mass with water instead of milk?
Yes. It can be mixed with either water or milk. Milk will increase the calorie content and provide a creamier texture.

What makes Mutant Mass different from other mass gainers?
It uses a Smart Carb Blend of maltodextrin and SusCarb (Highly Branched Cyclic Dextrin) and includes a whey protein matrix with digestive enzymes to support digestion of the high-calorie formula.
