Fuel Your Workouts

Organic maltodextrin is a complex carbohydrate that will give you a boost in calories and energy1. A pre-workout shake with Naked Mass can provide that extra fuel to power you through an intense workout. Evidence has shown that supplements with maltodextrin can help maintain anaerobic power to promote strength and exercise performance2.

Meet Daily Calorie Requirements to Gain Weight

Meet Daily Calorie Requirements to Gain Weight

If you're someone that's considered a 'hard-gainer', it can be quite a challenge for you to eat a surplus of calories to gain weight. Naked Mass contains 1250 calories and 252 grams of complex carbs in each serving, making it much easier for you to get the additional calories you need.

Build and Sustain Muscle Mass

Build and Sustain Muscle Mass

If you want your weight gain to be mostly lean muscle mass, then it's not just about a calorie surplus. You also need to pay attention to protein intake to promote muscle growth. Naked Mass includes Naked Whey, a fast-absorbing protein to aid quick muscle recovery after exercise. Naked Casein, a slow absorbing protein that takes several hours to digest, keeps your muscles nourished throughout the day3.

Frequently Asked Questions

Maltodextrin helps thicken the product and bind the ingredients together. Most manufacturers will choose to use wheat-derived maltodextrin which may pose health concerns due to containing gluten. Naked Mass only includes Organic Tapioca Maltodextrin that is gluten-free and does not pose the same concerns. We also ensure that our ingredients are never treated with pesticides.

Naked Mass is for anybody who's looking to gain weight or gain muscle, regardless of whether you regularly go to the gym or not. This mass gainer is also great for those who need to restore their weight, struggle to put on weight, or struggle to maintain a higher weight.

If you're regularly consuming Naked Mass, results can become noticeable in as soon as 2 weeks, but this depends on your overall diet and activity level. Weight gain is a direct result of consuming more calories than you're burning off, so you need to ensure that you're maintaining a calorie surplus to see results.

Yes, Naked Mass is suitable for teenagers. This product only contains three ingredients (organic maltodextrin, Naked Whey, and Naked Casein) and does not contain any hidden extras or harmful additives. We recommend using Naked Mass in-between meals or just before bed to quickly and easily add more calories to your daily intake.

We recommend only consuming up to 2 servings of Naked Mass per day. While consuming two servings instead of one will increase your calories significantly, your results depend on your activity level and overall diet. Likewise, instead of having multiple servings a day, you can dress up your own protein shake with various other calorie-dense ingredients.

Naked Mass is an ideal weight gainer for anybody without a lactose or dairy sensitivity who's trying to gain weight or maintain their weight. Whether you go to the gym or not, Naked Mass is going to provide the necessary nutrition to help you gain weight in a healthy, safe way. If you suffer from a dairy or lactose intolerance or follow a plant-based diet, we offer Vegan Naked Mass which also provides a full amino acid profile and quality nutrition.

Lara Balint
Not Bad Not Great

Positives no bloating definitely taste better than some. Cons even when shaking up my shake daily has a strong salt flavor

Lara Balint
Great Flavor

Has amazing flavor and gives zero bloat like most other gainers

Sam Szanczuk
Oh my fuck this is good

I've tried a handful of protien powders and mass gainers and this one by far tastes the best. At some point when I was a kid I made my own chocolate milk powder with just sugar and coco powder and that is exactly what this tastes like. And it's basically the same price as the other brand that I was using for the last year that I thought tasted kind of funny.


I haven’t used this long enough to see results- but it tastes SO much better than I thought it would. Shipping was quick. Excited to see what the results will be.

Peter R

Tasteful and greate for smoothies

So far, so good

Decided to switch to this from the Vegan powder. This mixes nicely to make a protein filled green juice to drink with breakfast. So far no bloating or other GI issues. Hopefully will aid in weight gain and retention which is my challenge. Love the fact that it's unflavored.
