MUTANT Mass Gainer - Chocolate Fudge Brownie - 49 Servings

If you’re serious about putting on size, this is one of the highest-calorie, most proven mass gainers I recommend, especially if eating enough food is the biggest thing holding you back.

MUTANT MASS is built for hard gainers, strength athletes, and anyone in a serious bulking phase who needs real calories, quality protein, and consistent results.

Why I Recommend MUTANT MASS

Massive Calories for Real Weight Gain

Each full serving delivers 1,100+ calories, making it far easier to stay in a calorie surplus without force-feeding solid food all day.

Whey + Casein Protein Blend

You get fast-digesting whey for post-workout recovery and slow-digesting casein to support muscle growth for hours after your shake.

High Carb Content for Performance & Size

Loaded with carbs to fuel hard training sessions, refill glycogen, and support weight gain, exactly what most skinny lifters are missing.

Great Taste & Easy Mixing

The Chocolate Fudge Brownie flavor mixes smoothly into shakes and smoothies and actually tastes good, even at higher calorie doses.

Flexible Dosing (Beginner or Advanced)

You don’t need to start with full servings. I often recommend ½ servings for beginners or splitting doses throughout the day to keep digestion comfortable.

How I Suggest Using It

• Post-Workout: Fast calories + protein when your body needs it most
• Between Meals: An easy way to boost daily intake
• Morning or Night: Perfect when appetite is low

Pro tip: Blend with milk, oats, nut butter, or banana to push calories even higher.

Who This Is Best For

• Hard gainers & ectomorphs
• Bulking athletes & lifters
• Anyone struggling to eat enough calories
• Off-season mass phases

Who Might Skip It

• If you’re cutting or maintaining weight
• If you already hit calorie goals easily with whole foods

If your goal is size, strength, and scale weight, MUTANT MASS is one of the most efficient tools you can use. I recommend it because it works, it’s consistent, and it removes the biggest barrier to bulking: getting enough calories every single day.
