Fuel Your Workouts

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. Chocolate Peanut Butter Naked Mass contains 1280 calories 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.

The only difference between Chocolate Peanut Butter Naked Mass and Naked Mass is that the chocolate peanut butter flavor contains a few more ingredients for the flavoring. Chocolate Peanut Butter Naked Mass does contain more calories per serving, but both products aid weight gain equally. How soon you see results is also dependent on your overall diet and activity level.

If you’re regularly consuming Chocolate Peanut Butter Naked Mass, results can become noticeable in as soon as 2 weeks, but this depends on your overall diet and activity level.

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.

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.

Couldn't be happier!

Got my Naked Mass (Vanilla) in a few weeks ago & have been making shakes with it everyday. This is by far the best tasting protein supplement I have ever tried. Will absolutely order again after I try the chocolate. I don't weight much for my height, so I absolutely needed something like this to have in between meals.

This stuff works!!

I have been wanting to gain weight so bad these last 2 months. I heard about this product and ordered it. Im not writing a review just to write it. This stuff actually works. I gained 8 lbs in a week and a half. I give myself a break on the weekends from it and I look forward to taking it every Monday-Friday. I do my scoops, ice, milk, peanut butter and cocoa. its so good. This protein shake size is perfect!!! Thank you

Exactly what I've been looking for

I prefer the unflavored. Waking up and tasting chocolate, vanilla, or strawberry each day just dont sit right with me. Been drinking this for 2 weeks now, paired with working out 3x a week and my wife says she can tell a difference already. Im what you call a hard gainer so it's tough for me to put on weight. I take the 4 scoops every morning and that's it. That's my breakfast. Through the day I eat like I've always eaten. I dont force myself or anything.

This is the lowest cholesterol option available.

From all the time I have spent searching for the perfect Mass gainer/Protein powder I found this one has the lowest cholesterol. I have cholesterol issues so I had to find something with the lowest cholesterol which can also help me with gaining weight and workout. This was the best option I found and this is made out of natural ingredients which is even a bigger plus.

Perfect weight gainer

Have been on the intermittent fasting schedule for the past year or so now and loved it, however I realized that I lost about 20-25 pounds gradually, over these 12 months. Being 168 now down from 185-190 (6 feet tall), I need to bulk back up. Im currently taking 2 scoops (half serving) adding about 650 calories to my diet daily and adding another 300-500 of food spread out more than I usually had. Im up 8 pounds in a week, with zero stomach issues. Drink it slow and let your body adjust
