Mutant Mass has truly transformed my fitness journey! The Triple Chocolate flavor is a game-changer - it tastes like a classic milkshake. I religiously consume it twice daily, post workout especially. Not only did it aid in my recovery, but I also noticed significant gains in muscle mass. If you're looking to pack on quality mass and enjoy the process, Mutant Mass is the way to go!*

I’ve had a lot of chocolate bulking flavors but this one is the best in terms of the right sweetness. Very easy to mix even easier with some ice thrown in. Water mix is better than you’d think and in a pinch worth it to the picky sippers. No bloating to little if you’re pounding 3 scoops. Repeat buyer for sure. *

Hands down best mass gainer on the market. Some gainers have too many calories or carbs vs protein but this is well balanced, the OG Mutant Mass is right on the money*

I give cookies and cream four stars on flavor. The reason for 3 stars overall is that it gives you bad gas problems. I'm having gas issues on just 2 scoops at a time. I would hate to experience a full dose(4 scoops).*

I got this for my 15yr son to put on some sizes. He very picky so I was surprised he liked the taste. He said it gives him lots of energy to workout. It doesn’t bother his stomach and mix easily. He’s put on 3lbs only talking two half severing a day.*

The taste to me is really good. It mix very easily in milk or water. The cookies  Chrome are crunchy at first but as it sits they get softer. Mixed in water I have no stomach issues like I have with milk. I’ve put on 3lbs so far from taking two shakes a day. Good stuff. *

At time mutant mass can be a little thick especially when mixed with something other than water but other than that it was a great product and provided lots of calories and carbs.*
