The Worst   Jagjit Singh, Auckland
The worst mass gainer , has to much sugar and fat. products like serious mass or supermass is much better. Tried this product couple of times , taste is great but i just gained fat from it , not very useful. the product price is very reasonable for the amount of servings but product quality is not the best , would not buy it again.

Testing  mikaere bell, Te Kuiti
just started using mutant mass this Monday, so far taste has been great! I ordered strawberry and banana flavor 15lb. I take 4 scoops with 600ml of water and is quite easy to chug down. haven't had any gas problems so that's A+ haha but looking forward to seeing if this supplement lives up to its name! will post another review once I have completed the bag . cheers

Good  Jackson Anderson, Highbury -Palmerston North
Been using it for two years, the only real solid Mass Gainer out there, great tasting, BUT, recently got the Hazelnut flavour and it is the most horrid tasting shake ever, can not finish a whole shake. Chocolate all the way
