Serious mass gainer with solid results!
Mutant Mass helped me pack on calories and size — mixes well and tastes decent (especially chocolate). It’s definitely a heavy gainer, so good if you’re struggling to hit your calorie goals. A bit thick sometimes and not for light eaters, but overall a great choice if your goal is muscle growth and weight gain.

Delicious and effective
I have purchased as many times and it has helped me so much. I was 110 lbs and it's got me up to 130. Tastes way better than all the other stuff that I've tried. If I ever need this again I will definitely repurchase it over and over and over again.

🚨Caloric Claims Are Incorrect
I triple checked their claims in the Amazon descriptions and theyre wrong. The nutrition facts on the back of the bag state it’s 550 calories per 1 serving and each serving is 2 scoops. The Amazon description claims it’s 1100 calories per serving which is incorrect. Other than that, the taste is great.

Love the results, not the marketing
I’m not a powerlifter or bodybuilder. I train predominantly with bodyweight, kettlebells, and heavy clubs. After having trouble making progress in strength despite a good nutrition and rest, I switched from my usual True Nutrition protein to this. After going through one bag, I have seen a marked difference in muscle gain. The taste is great and mixes better than the other protein I was using, which would turn frothy when either shaking or blending it. This powder doesn’t do that. The only drawback to me is the marketing. It’s so asinine and cartoony with it’s over the top teenage testosterone-charged font and design with every model in their ads looking like characters from the MCU. In fact when I first learned about this powder I passed on it because of the marketing. To me to reeked of the typical type of hyped marketing that’s common among fitness nutrition companies. But when I saw the results from one athlete I follow, it was enough to get me to try it. The price point is also competitive too. There’s a slew if other protein powders that contain less nutritional value and cost more than double. In the end I learned that this proverbial book is leaps and bounds better than its cover.

Great product
I took this for about 4 months and was able to put on about 6 to 8 lbs of muscle. I cut my carb intake back while using this product. Be careful because you will gain quickly.
