Mutant Mass — The Original Big Bag Gainer for Relentless Size

If you struggle to eat enough to grow, Mutant Mass does the heavy lifting for you. This is the legendary mass gainer trusted by lifters and athletes across the globe since 2005—rebuilt to be even better. Designed for the strong, the hungry, and the truly dedicated, Mutant Mass delivers a powerful hit of calories from clean, food‑based sources to help you move the scale, fill out your frame, and recover harder between sessions.

Why Mutant Mass Works

Calorie surplus made simple: Building size requires more calories than you burn. Mutant Mass makes hitting that surplus easy with a dense, satisfying shake you can drink any time you can’t face another plate of food.

Multi‑phase protein support: A blend of fast and sustained‑release proteins helps feed muscles for longer—ideal after brutal workouts and during busy days when meal timing isn’t perfect.

Real food carbs for real performance: A focus on nutrient‑dense carbohydrates helps fuel training, drive recovery, and support fuller, harder muscles.

Smart calories, serious flavour: Thick, creamy, and genuinely enjoyable—so you’ll actually stay consistent. Mixes well with water or milk and stacks easily with your favourite supplements.

Who It’s For

  • Hardgainers who need an easy way to increase daily calories and protein.
  • Bodybuilders and strength athletes in off‑season or bulk phases.
  • Busy trainees who want a convenient, nutrient‑dense meal alternative on the go.

How to Use for Best Results

  • Have a serving between meals to drive up daily calories without feeling stuffed.
  • Use after training to support recovery and muscle growth.
  • Adjust serving size to your goals: start smaller and build up as your appetite allows.

What Sets It Apart

  • Proven pedigree: Millions of servings in 100+ countries—Mutant Mass is a gainer with a track record.
  • Food‑first formula: Built around nutrient‑dense, clean ingredients, not empty calories.
  • Great value per serving: Big bag, big gains—ideal for long bulks and high‑output training blocks.

Stack It

Pair Mutant Mass with creatine, essential fatty acids, and a solid training plan for a complete mass‑building stack. Consistency is everything—train hard, eat big, sleep deep, repeat.

WE ARE MUTANT. When it’s time to leave average behind, grab the original big bag gainer and go build something monstrous.
