When “Eating More”
Isn’t Enough

Are you sick of eating “broccoli and rice” every 30 minutes... followed by bananas and peanut butter... and then a protein shake... and STILL have little gains to show for it?

It can feel discouraging (not to mention a big waste of time and money), especially if you’re a “hard-gainer” with a fast metabolism... where no matter how many “calorie-dense” foods you consume, you can’t put on the muscle and size you deserve.

That’s why so many men and women (and even underweight kids and teens) will turn to a ‘gains formula’ to help put on more weight fast without having to constantly be eating all hours of the day and feeling sick to their stomach.

Increase Gains (Not Fat)
Faster And More Efficiently

Crazy Nutrition’s MASS GAINER formula packs every serving with 488 calories — including 55 grams of carbohydrates and 40 grams of protein.

But what REALLY makes MASS GAINER better than any other gains formula?

We added a cutting-edge, patented enzyme blend that is backed by science to IMPROVE absorption rate and digestion — ensuring your body utilizes all of the ingredients without waste or bloating.

If you are not 100% satisfied with your experience using our MASS GAINER formula— and if you don’t begin to put on incredible gains, and in as little as 2 weeks’ time — then you can return it for a full refund and we won’t hold it against you.

  • Delicious chocolate & vanilla flavors
  • Made with DigeZyme® to avoid bloating
  • Added B vitamins for extra energy boost
  • Plus Black Pepper for Better Absorption
  • New! Added MCT Oil for Healthy Fats

What You Can Expect With Crazy
Nutrition’s MASS GAINER

Increased Gains

Each serving of MASS GAINER contains a whopping 487 calories, 40 grams of protein, and 55 grams of carbohydrates. When added to your daily exercise routine, you can begin to expect ‘massive’ gains in as little as 2 weeks!

Speedy Muscle Recovery

Not only are you getting 40 grams of protein to help with muscle recovery, but you’re also getting zinc and magnesium — two minerals that support muscle healing and recovery. We've also added DigeZyme, an enzyme blend that is proven to decrease the pain caused by intense workouts, so you can get back to the gym ASAP.1

Energy Without The Crash

Packed with protein, complex carbs, B vitamins, and MCT oil, MASS GAINER can give your brain and body the boost it needs to stay focused and push harder without drastically spiking your blood sugar levels and causing you to crash.

What’s Inside MASS GAINER?

Our MASS GAINER formula contains only whole-food sourced ingredients,
without maltodextrin or other stomach-churning fillers

  • Gluten-Free Oat Flour

    Oat flour is high in complex carbohydrates which can naturally help boost gains, help you feel full, improve digestion, and support healthy blood sugar levels.

  • MCT Oil

    This super easy-to-digest form of fat (from coconuts) adds massive calories and is quickly converted into energy you can use to fuel intense workouts.

  • Whey Protein Blend

    Our blend of whey and milk proteins delivers an impressive 40 grams of protein and a rich amino acid profile.

  • B6 + B12

    These brothers from the B vitamin family are critical for healthy energy production (and most people are deficient).


    Besides supporting protein synthesis, these immune-boosting minerals also defend against fatigue and sickness brought on by intense training.


    This blend of 5 enzymes improves absorption and minimizes digestive discomfort — it's also proven to reduce delayed onset muscle soreness.1
