Mutant Mass Reviews

4.5/5 based on 21 customer reviews

  • Great product, still think mutant is number 1 product. Got gains really quickly and put on enough weight to bulk.
  • Be taking it for about 2 weeks now the chocolate taste ok
  • Great taste, good value and it really works.
  • I have tried triple chocolate and cookie and cream. I think it's too sweet. The supplement doesn't mix very well. I had to use a blender instead of a hand shaker because it wouldn't mix but atleast the supplement does its job**
  • Love this supplement, thoroughly enjoy the Triple Chocolate flavour the most. Prefer to have with water and still tastes great, that way am able to have a couple of shakes rather than with milk as it makes you more bloated. Have taken for a couple of years for the off season for rugby and taken in 6 month stints and definitely seen results being able to gain over 5kg ever time which is good for me as i can't gain weight that easily. Highly recommend this if you want to gain weight!
  • Can't comment on results yet as only just purchased. Just want to warn others, this has a very sweet taste (Vanilla). Previously used BSN Truemass 1200 which was easier to drink (less sweet taste). This is going to be very hard to get through lol. Will post back regarding results. Using 2 scoops per serve/day (approx 120gram)
  • Decent gainer this one, gives ya made ga. Tho
  • 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!
