I’ve Used 2 Bags Of Crazy Nutrition Mass Gainer (My 2024 Review)


Are you tired of eating yourself sick? As a skinny hard gainer, I know the feeling all too well. I did not stop eating until I was so full that I couldn’t stand up for years. When you become bored of eating, the concept of drinking a shake at least offers your jaw a break!

You may have tried a couple of mass gainers previously. Some taste acceptable, some cause bloating and gas, and some are simply horrible. How does Crazy Nutrition Mass Gainer compare to the industry’s biggest names?


  • Natural carb sources come from whole foods.
  • Digestive enzymes help to minimize bloating and stomach pain.
  • Reformulated to have fewer carbohydrates, becoming the ideal meal replacement.
  • It tastes like a light chocolate shake.
  • Muscle & Health magazine provides free lifetime access.
  • A 60-day money-back guarantee allows you to try without risk.


  • Poor choice of flavors, with only chocolate and vanilla available.

Quick Verdict

Crazy Nutrition Mass Gainer Review

An in-depth study of Crazy Nutrition’s Mass Gainer must go beyond the conventional flavor and mixing characteristics. We need to dig deeper and examine the formula to determine whether it is worth it.

So, let’s start with the ingredients. The flavor and mixing ability of a product is irrelevant if it lacks the necessary components and ratios.


Crazy Nutrition Mass Gainer Ingredients

I’m going to state it from the start. I really like the ingredients in Crazy Nutrition’s Mass Gainer. There are very few gainers on the market that get their carbohydrates from natural food sources.

Instead, companies frequently utilize inexpensive carbohydrate fillers such as maltodextrin. Maltodextrin has a purpose. For example, it’s a simple and easy way to fuel a hard workout, providing quick energy.

However, it is practically pure sugar with no sweetness, so if you’re using mass gainer as a meal replacement, there may be better options.

Crazy Nutrition deviates from the norm by filling the carbohydrate content from a variety of natural food sources. Here’s a brief overview of the main ingredients:

  • Gluten-free oats
  • Pea starch
  • Whey protein blend of whey isolate and concentrate
  • Sweet potato flour
  • Creatine monohydrate
  • Flaxseed powder

These are the main components of the Mass Gainer. Let’s look at each ingredient and why it’s an excellent addition to the Crazy Nutrition Mass Gainer formula.

Gluten-Free Oats

Oats are a staple carbohydrate for everyone, from fitness enthusiasts to professional bodybuilders. They are high in fiber and slow to digest, with the added benefit of containing minerals like magnesium and zinc.

Pea Starch

Many vegan and vegetarian supplements use peas to deliver protein in powdered form. However, they also serve as a good supply of carbohydrates. You also get an adequate vitamin K, fiber, and zinc supply.

Whey Protein

Of all protein sources, whey protein has the most essential amino acids (EAA). EAAs are needed because your body does not produce them. Thus, you must consume them through diet, as they are required for muscle growth [1].

Sweet Potato Flour

Sweet potatoes are an excellent source of both vitamin A and B6 on top of being a carbohydrate. It’s high in fiber and contains the antioxidant beta-carotene.

Creatine Monohydrate

Creatine is one of the most well-researched and efficient sports supplements on the market. Taking creatine on a regular basis boosts strength by 8% compared to a placebo and the number of reps performed with a given weight by 14% [2]. All of this translates to bigger muscle mass growth.

Flaxseed Powder

Optimal omega-3 fatty acid intake must not be overlooked. The bioavailability of omega-3 fatty acids from animals makes them the superior supplementing choice, yet there’s no way to incorporate fish oil into a mass gainer without sacrificing flavor.

On top of that, it cannot be ground into a powder. An outstanding option that does not involve animal products is flaxseed.

There are more ingredients added to Crazy Nutrition’s Mass Gainer:

  • Panax Ginseng
  • Digestive enzymes

Panax Ginseng is derived from traditional Chinese medicine and has made its way into the Western world. Most traditional Chinese ingredients lack scientific backing, but Panax ginseng is an exception.

Panax Ginseng has been linked to improved memory, attention, mental health, and social functioning [3][4]. I would say these are pretty good side effects for a bulk gainer.

Digestive enzymes are an extra benefit of the product. They are added to break down lactose, carbs, protein, and fat, preventing bloating and gas.

Macronutrient Breakdown

Crazy Nutrition Mass Gainer Old And New

Of course, the protein, carbohydrate, and fat ratio will determine whether a bulk gainer is worth it. Crazy Nutrition has altered its original recipe, packaging, and container size. Here is how the old macronutrient breakdown looked:

Protein51 g
Carbohydrates100 g (6 g from sugar)
Fat8.8 g

And the current breakdown:

Protein40 g
Carbohydrates55 g
Fat10 g

As you can see, the amount of carbohydrates per serving has been nearly cut in half. The protein has also been lowered, reducing the caloric content per serving, which is something I love. I’ve addressed this issue numerous times in other mass gainer articles: avoid mass gainers with absurd serving sizes.

The Crazy Nutrition Mass Gainer nailed it. You can add one serving to your regular diet without exceeding your planned calorie surplus, limiting fat gain.


This gainer is offered only in chocolate and vanilla to ensure the product tastes great. In my opinion, it is better to do two flavors well rather than several with some tasting awful.

Crazy Nutrition has gone this route, and the Mass Gainer tastes exactly as good as the company’s protein supplement.


Surprisingly, the Crazy Nutrition Mass Gainer blends really smoothly, even when mixed with water. Just keep in mind that the recommended 400-500 mL of water per serving is insufficient to ensure a thorough mix.

Most companies recommend 400-500 ml for mass gainers, which is never enough, and Crazy Nutrition just follows the trend. Simply fill your shaker to the maximum capacity, or use a larger bottle if you want it mixed well. 


Mass Gainer By Crazy Nutrition

Yes, there are cheaper bulk gainers on the market. However, this is due to their use of cheap fillers to raise the calorie count to sell their products at a low price.

Crazy Nutrition uses natural food sources, making it unable to match the same price expectations. Here’s what to expect and how to receive a discount by purchasing in bulk.

1 bag (20 servings) costs $89.99 or $62.99 on a subscription.

That’s $4.50 per serving or $3.15 per serving on subscription.

You can do it all risk-free thanks to the 60-day money-back guarantee. If you are unsatisfied, you can receive all your money back.

No gas or bloating will occur because of the digestive enzymes that have been added. But there will be a lot of liquid in your stomach!
