Crazy Nutrition Mass Gainer Ingredients

The main ingredients in Crazy Nutrition Mass Gainer are oat flour, maltodextrin, whey protein, milk protein, vitamin fortification, and supplementary minerals. These are supported by added digestive enzymes and absorption aids to boost results.

The carb combination of oat flour and maltodextrin is a great choice for basic, medium-speed absorption. These provide sustainable carb energy while still being effective as a post-workout carb source to kickstart energy repair and muscle growth (1).

The protein blend is similarly well designed. The whey protein is perfect for short-term effects, especially post-workout.

The milk protein combines stable whey and casein, together, to provide the medium- and long-term benefits you need for better muscle growth and recovery. This is a simple but powerful protein combo for mass gain.

Secondary Ingredients: Metabolism, Energy, and Recovery

The vitamin support – B6 and B12 – are great for metabolism and energy efficiency. These help you get energy and other nutrients from food, improving energy metabolism and function in the cells.

The mineral complex is great for you, too, combining magnesium and zinc. Magnesium is one of the most important minerals for anyone performing exercise, as your needs spike, while magnesium offers a powerful suite of benefits to muscles (2). Zinc helps regulate growth and energy metabolism, making it another great choice for mass gainers (3).

Finally, you’re getting a huge boost in the digestive quality and efficiency of this product. This is because of the combination of powerful digestive enzymes to help absorb carbs, fats, and protein.

Piperine is a black pepper extract that complements these benefits, improving intestinal absorption of all of these nutrients.

Crazy Nutrition Gainer Macronutrients

A single 125g serving of Crazy Nutrition Mass Gainer typically contains:

  • 488 Calories
  • 32g Protein
  • 44g Carbohydrates
  • 8g Fats

This makes Crazy Nutrition Mass Gainer a very lean mass gainer, offering a near-perfect amount of calories to make a maintenance diet into a high-quality bulk. It’s below 500 calories, but has a huge 1.4 to 1 ratio of carbs to protein.

Crazy Nutrition Mass Gainer Review

This high ratio causes 2 major benefits you need to know:

  1. It has a better effect on muscles and les all-purpose calorie content
  2. It’s suitable for use at any time of day, as well as a powerful post-workout shake

These are only 2 of the benefits of this product, so we need to look at the other key benefits you can expect from this product…

Crazy Mass Gainer Benefits

The main benefit of Crazy Nutrition Mass Gainer is a boost to the quality and quantity of weight gain. It can turn a maintenance diet into a nearly-perfect bulk, with around 500 calories of calorie surplus and a powerful 1.5-to-1 ratio of carbs to protein for muscle growth.

This ratio is fantastic for promoting muscle growth, as the main target of weight gain for bodybuilders, athletes, and fitness enthusiasts alike. The clean formula and protein focus also make it a versatile way to accelerate weight gain and muscle growth.


This is perfect if you want to gain muscle, but are concerned about overeating and unwanted fat gain. This is where Crazy Nutrition’s mass gainer is a better choice than many high calorie ‘super mass gainers’ on the market.

One benefit you’ll notice using this product is a serious improvement to muscular recovery and growth, as well as strength and power performance. The high protein content makes it a great way to improve performance metrics and exercise outcomes.

Recovery Post Workout

You’ll get stronger faster, recover better between workouts, and drive up your performance in whatever fitness goals you’re chasing. The combination of protein and carbs is synergistic for this: they’re more powerful combined than apart. This is one more reason to replace your protein shake.

It’s a great post-workout shake, in particular, where the close ratio of protein and carbs is incredibly powerful. This is backed up with the added magnesium, which is a common athletic performance and recovery supplement used by Olympians and elite bodybuilders.

Digestive Benefits

Finally, the benefits of added digestive enzymes and piperine are potent. 

  1. First, they ensure you’re getting more from each gram of protein or carb you consume. These ensure that your single serving is as powerful as possible, a way of driving up your total results, and getting the most for your money
  2. Second, they make the process of using a mass gainer more comfortable. The added benefit is that your gut is more comfortable, especially powerful if you typically respond poorly to supplement powders. These are backed up by the multi—source protein and carbs, which are typically better for the gut.
  3. Finally, they actively make secondary ingredients more powerful. The absorption and use of vitamins and minerals are much better with these aids – especially piperine – in the system. This is a great synergy to make sure every single part of the mass gainer is doing its job to the max.

Our Verdict

Crazy Nutrition Mass Gainer is one of the best lean mass gainers on the market with both powerful main ingredients and excellent secondary support. It has well-rounded benefits and is a nearly perfect serving size and calorie content for transforming a maintenance diet into lean muscle growth.
