  • tried this mass gainer couple of times , did not gain anything but fat. to much sugar and fat , taste probably the best. pretty cheap for a gainer. this product may be good but for me , it did not work. i would rather stick to serious mass or super mass.
  • I wanted to gain some size and asked around which is the best mass gainer. Everyone I have talked to recommended Mutant Mass. They are not wrong and I absolutely love it. Im 5'11 and since 2014, I have gained 20kg from 67kg. Great taste and mixes very well. I have experimented with other brands but this one is definitely one of the best. Highly recommended.
  • I'm 5'8 69kgs before I started using this mass gainer. I've been very desperate to gain some good mass. In the beginning I was skeptical that it would actually work but I was dead wrong. I'm currently my 2nd bag and I've gained solid 6kgs of mass. You just have to watch out the massive flatulence at the beginning but your body adapts eventually but I noticed that you should have a bit to eat rather than an empty stomach. Since then I've never had any trouble with any toilet run. During training days. I'm taking this with 3 scoops in the morning with small leafy meal. 2 scoops at lunch time then 3 scoops straight after workout. On non training days, just 2 scoops in the morning. A serving of a normal protein shake then 2 scoops in the arvo. Nevertheless, I'm very very happy with this product and will use it again till I reach 78kgs+. Lastly, I've just purchased my third bag before writing this review! that's how much I love this. Thanks Sprintfit! The BEST pricing in NZ!
  • So far one of the best gainers i have ever had, taste is amazing, could also mix with frozen fruit and milk which gives you more calories and protein.
  • I think they have changed the formula or at least the taste of the triple chocolate, good product but liked the old taste better.
  • Great Mass Gainer! Have been taking this for the last month and have found great gains over this time. Tastes great but my only slight issue is mixing but I jus t shake for a little longer and it dissolves aventually.
  • Overall one of my favorite mass gainers, they give you a good amount of calories, carbs and protein. Most company's skip out on one or two of these 3 things. Mutant has been one of my go to brands for the last 6+ months, they give a quality product for a quality price.
  • I really liked the flavor of the MUTANT Mass. Tasted like cold hot chocolate. I liked the label with all the amounts of amino acids on the sides, really lets you know what you're getting. It also has great amount of carbs and potassium.
  • Giving this a try, workouts every 2nd day. 3 shakes a day, hitting the heavy weights :) Up about 4 kgs in little over a week with no discernable change in body fat. Make sure you do situps and cardio as it's easy enough to get a gut, and go hard people :)
  • Awesome product - I am a classic example that this stuff actually works. I have been using this for the last seven months, more than half way through my 3rd bag of Mutant Mass. My starting weight was 60KGS, I now weight in now at 76.5KG, lets see if i can reach 80kgs by the end of it. Train hard, eat well and Mutant Mass.
