While many mass gainers are incredibly high-carb and high-calorie, Crazy Nutrition offers a more moderate formula. At 488 calories per serving with 39-40g of protein, Crazy Nutrition is different from many other mass gainers that contain well over 1000 calories per serving. 

This makes it a great choice for anybody looking to gain weight, without consuming too many unnecessary calories from added sugars or other filler ingredients. 

Crazy Nutrition Macronutrients Breakdown

Below we’ll be taking a closer look at Crazy Nutrition’s macro breakdown and ingredients, so you can see if it’s a good fit for your needs. 

1. Source and Amount of Protein per Serving

First, we’ll be looking at Crazy Nutrition’s protein content which comes from whey protein concentrate and milk protein concentrate. Compared with isolates, concentrates are a less refined form of protein powder, meaning they contain more carbs and fats.

For the sake of weight gainer supplements, which tend to include high amounts of carbs, whey concentrate is an ideal protein source. 

Each 125g serving of Crazy Nutrition contains 39-40g of protein. If you’re looking to gain muscle, we recommend eating 0.7-1g of protein per pound of body weight each day. So, Crazy Nutrition’s protein content should still help you hit your protein targets more easily. 

It’s worth noting that because of the large serving size, Crazy Nutrition contains significantly more protein per serving than most standard protein powders. However, this is also quite a bit less protein than some other higher-calorie mass gainers out there. Keep this in mind when choosing which protein powder or mass gainer is best for you. 

2. Source and Amount of Carbs per Serving

Along with 39-40g of protein, Crazy Nutrition also contains 55-57g of carbohydrates, which is where the majority of this supplement’s calories come from. These carbs are broken down between oat flour and maltodextrin, which are both fairly standard carb sources for weight gainers. 

Crazy Nutrition is relatively low in sugar, with 7-8g per serving. However, this means much of its sweetness comes from the artificial ingredient sucralose, which some people may prefer to avoid. 

As you can see, Crazy Nutrition has an approximate 1.3:1 ratio of carbs to protein. This is uncommon with mass gainers, which often contain up to 5 times the amount of carbs as protein. This makes Crazy Nutrition a better formula for maintaining a moderate caloric surplus, as we’ll be covering in more-depth later on.  

3. Fats per Serving

Finally, Crazy Nutrition also contains 10g of fat per serving, with some of them from MCT oil powder. Keep in mind that 6-7g of this fat is saturated, which may be worth keeping in mind if saturated fat is something you’re looking to limit in your diet.

However, this is still a relatively low amount of saturated fat compared to many other weight gainers out there. Keep in mind that MCT are also saturated fats but we should look at them differently. 

4. Calories per Serving

Finally, all these macronutrients add up to give Crazy Nutrition a total serving size of 488 calories. While this is a much higher-calorie supplement than most standard protein powders, in terms of weight gainers it is fairly low-calorie. For reference, many mass gainers out there contain well over 1000+ calories. 

While this may seem like a downside, this means Crazy Nutrition is also less likely to send you into an excessive caloric surplus. We recommend sticking to a caloric surplus of 250-500 (or 5-10% of your total maintenance) calories per day to avoid unnecessary fat gain. It will likely be easier to stay within this range using a more moderate supplement like Crazy Nutrition. 

3 Key Advantages of Crazy Nutrition Mass Gainer

Now that you have an idea of Crazy Nutrition’s macronutrient profile, let’s break it down a little further, looking at some key advantages this supplement offers compared to other mass gainers. Some highlights include its low carb-to-protein ratio, high-fiber content, and moderate calorie count. 

✅ Ratio of Carbs to Protein

One advantage to Crazy Nutrition’s mass gainer is its low ratio of carbs to protein. Each serving has a roughly 1.3:1 ratio of carbs to protein, while many other mass gainers contain much more carbs compared to protein. This lower ratio will make it easier for you to hit protein targets without eating a ton of extra carbs, potentially leading to an excessive caloric surplus. 

✅ Contains ~6g of Fiber per Serving

Next, each serving of Crazy Nutrition contains a nice ~6g of fiber. With the recommended amount of daily fiber being 25-35g, an extra 6g will go a long way in helping you hit this target range. 

With high-fiber diets being associated with better overall health and disease prevention, fiber is something everyone should be prioritizing in their diet. So, make sure you’re also eating plenty of fruits, vegetables, and other fiber sources to make sure you’re getting enough in your diet. 

✅ Low Amount of Total Calories

While Crazy Nutrition is much lower in calories than many other mass gainers out there, in our opinion, this is an advantage. With many mass gainers, we recommend taking smaller serving sizes so you’re not eating in an excessive caloric surplus. With Crazy Nutrition only having 488 calories per serving, using smaller servings likely won’t be as necessary. 

However, depending on your goals and current diet, using a smaller serving may still be ideal. Regardless, Crazy Nutrition’s standard serving size of 488 calories is much more reasonable than many other mass gainers that contain well over 1000 calories per serving. But as always it depends for who and when. 

✅ Free Worldwide Shipping

Finally, a major pro of Crazy Nutrition is that it offers free worldwide shipping on all orders over $60. With mass gainer being a heavy product, shipping costs can be very expensive from other brands that don’t offer free shipping. This is especially true if you live in a small or remote country where shipping tends to be more expensive anyways. 

Although Crazy Nutrition is fairly expensive per serving as we’ll cover more in-depth down below, the free shipping helps make it significantly cheaper than many other options out there.

Does this Mass Gainer have Significant Disadvantages?

While we’ve covered some of Crazy Nutrition’s main pros above, what about the cons? Below we’ll be taking a look at where Crazy Nutrition falls short compared to other mass gainers out there. This includes an unclear nutrition label, a high price point, and a lack of flavor variety. 

❌ No Listed Micronutrient Breakdown

First and foremost, while Crazy Nutrition advertises the fact this supplement contains B Vitamins, Zinc, and Magnesium, the specific amounts are not listed anywhere on their website. While these are all important for overall health, it’s impossible to recommend Crazy Nutrition as a source of these vitamins and minerals without knowing how much the supplement contains. 

❌ High Price Per Serving 

Crazy Nutrition also comes at a fairly high price point, especially considering the low amount of calories per serving. Each serving will cost you about ~$4.50, which is pricey, especially when compared with standard protein powders, and many other mass gainers. 

It’s worth noting that by subscribing, the cost does drop significantly to ~$3.15 per serving, which is a much more reasonable price in our opinion. However, you may not want to opt into a subscription before trying the supplement. 

However, considering Crazy Nutrition also offers free worldwide shipping, there won’t be any additional surprise costs at checkout when ordering this product. This adds significant value to Crazy Nutrition, especially for people in countries where shipping is often expensive.

❌ Limited Flavor Variety

Finally, while this is a minor issue, Crazy Nutrition does only come in 2 basic flavor options: chocolate and vanilla. If you’d prefer a more unique set of flavors to choose from, you may be interested in a product like MyProtein’s mass gainer, which we’ll be covering in more depth down below. 

How Do You Use Crazy Nutrition Mass Gainer?

Now that we’ve gone over Crazy Nutrition’s macro breakdown, as well as some pros and cons, you may be wondering, “How do you use this supplement?”

As mentioned earlier, we recommend using a mass gainer to help you reach a surplus of 250-500 calories. This may involve taking the full suggested mass gainer serving size every day, or only using a smaller amount when needed. 

If you plan on using smaller portions, each Crazy Nutrition serving contains 4 scoops, making it easy to split up if necessary. For reference, one Crazy Nutrition mass gainer scoop contains approximately 122 calories, 10g of protein, 14g of carbs, and 2.5g of fat. 

To make a mass gainer, simply blend together with milk or water and drink it like a regular protein shake! Crazy Nutrition recommends using 15-20oz of liquid per serving for optimal texture and consistency. 

Below we’ll be covering some additional questions you may have surrounding mass gainer, including how much weight you can expect to put on, and when to drink it during the day.

1. What are Expected 1 Month Mass Gainer Results?

The results you’ll see from a mass gainer supplement will depend largely on the rest of your diet. If you’re using a mass gainer to maintain a daily surplus of 250-500 calories, you will certainly gain weight. 

Of course, if you want to gain muscle, you have to be training properly as well. We recommend finding a plan that allows you to hit every major muscle group 1-2 times a week to ensure you’re building a well-rounded physique. 

If you practice consistent weight training and maintain a daily caloric surplus of 250-500 calories over a month, you can expect a weight gain of anywhere from 2 to 4lbs made up of mostly lean mass. Of course, if you’re eating in a surplus of 500+ calories, you’ll likely be putting on a fair amount of fat alongside muscle – so be careful!

2. Should I Drink Mass Gainer Before or After Workout?

We recommend drinking mass gainer after your workouts as a recovery drink. If you do plan on drinking mass gainer before your workouts, make sure you’re doing it at least an hour before you hit the gym to avoid feeling too full for your workout. 

It may be ideal to save mass gainer as a final meal of the day. This way you can easily adjust the serving size based on what you ate that day to hit your calorie target. While you may occasionally need a full serving, sometimes you may be able to hit your daily calorie goals without any mass gainer.

This approach will help you to not be completely reliant on mass gainer, and will promote a more balanced diet overall. 

The Final Verdict on Crazy Nutrition's Mass Gainer

Overall, this mass gainer by Crazy Nutrition is a solid supplement for anybody looking to gain weight. It ticks most of the boxes we look for in a mass gainer supplement, namely high protein content, and a moderate ratio of carbs to protein. 

With that being said, this product is pricey for the serving size. Additionally, standard whey protein powder may be a better, more budget-friendly option for most people. However, if you’re set on using a mass gainer, Crazy Nutrition is a solid option. 

Crazy Nutrition Mass Gainer Alternatives

Below we’ll quickly be looking at some alternatives to Crazy Nutrition so you can see what to expect from other popular mass gainers on the market.

Crazy Nutrition Mass Gainer vs. Transparent Labs Mass Gainer

First up is one of the most popular mass gainers on the market from Transparent Labs. While this is not an exceptionally high-calorie supplement, it does contain more than Crazy Nutrition with 750 calories per serving. This is broken down between 51-53g of protein, 110g of carbs, and 14g of fat. 

Like all other Transparent Labs formulas, this mass gainer is also made with all-natural ingredients, unlike Crazy Nutrition which contains the artificial sweetener sucralose. Transparent Labs is also third-party certified by Informed Choice, which guarantees a high overall level of quality. 

Similar to Crazy Nutrition, Transparent Labs mass gainer only comes in 2 flavors: chocolate and vanilla. 

Finally, it’s also worth noting this is a more expensive supplement at ~$5.33 per serving. However, in our opinion it still provides similar value to Crazy Nutrition because of its more substantial serving size. 

It’s also worth noting that Transparent Labs does not have the same worldwide free shipping policy as Crazy Nutrition, which may make it even more expensive in some countries. Transparent Labs also does not ship to several countries, making it completely unavailable to some.

Crazy Nutrition Mass Gainer vs. MyProtein Impact Mass Gainer

MyProtein Impact Mass Gainer

• Suitable for Vegans: No
• Flavors: Brown Sugar Milk Tea, Chocolate Smooth, Iced Latte, Strawberry Vanilla, Unflavored
• Calories per serving: 369-412 KCAL

Next is MyProtein’s Impact Mass Gainer, which is an even lower-calorie option than Crazy Nutrition. Each serving contains only 369-387 calories, broken down between 29-33g of protein, 45-52g of carbs, and ~5-6g of fat. 

It’s worth noting that MyProtein offers the most flavor variety out of the three products we’ve covered with 6 options to choose from. This is significantly more than both Crazy Nutrition and Transparent Labs which both offer only 2 different flavors.

At ~$2.84 per serving, MyProtein is significantly cheaper than both Crazy Nutrition and Transparent Labs. Just keep in mind that it offers a much smaller serving size and fewer calories than these alternatives as well. Once again, MyProtein does not offer free worldwide shipping, which may also make this product significantly more expensive in many countries.

Conclusion

Overall, Crazy Nutrition is a solid choice for anybody after a more moderate weight gain supplement. 

Crazy Nutrition doesn’t have the same 1000+ calorie serving size as many other mass gainers out there. However, its lower-calorie formula is better for maintaining the moderate caloric surplus that’s optimal for lean muscle gain. While it does have a few downsides – the high price point, and lack of micronutrient info, for example – this is still a great overall choice. 

If you’re interested in a high-quality, moderate mass gainer supplement, consider giving Crazy Nutrition a try today.
