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.

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.

Top tier! Extreme 2500 biggest bag is 12lb not 15
Best on the market. Taste amazing and very good at putting weight on. IMPORTANT- if you are buying the mutant mass extreme 2500: this is 4 scoops 2x a day and only goes up to 12lb bags. CLICKING the 15lb bag orders you their other type that is 2 scoops 1x a day with far less calories per serving. They are both good, but the 2500 is top tier
