5/5
I’ve been using Mutant Mass Gainer in the Vanilla Ice Cream flavor for a few weeks now, and it’s been a solid addition to my routine. The flavor is smooth and creamy, not too sweet, and mixes surprisingly well for such a dense gainer. I’ve tried it both with water and milk, and it tastes great either way—though I prefer it with water. If you're looking for a reliable gainer with a decent taste that does the job, this one’s worth a try!
5/5
Great product. Tastes nice with water or milk. Does everything you need for the price.

I love having this mass gainer. Whether in a smoothie, just some milk or water, I feel fuller after having this. It's a nice shock to the system after a workout

5/5
Good for morning smoothies and before bed. Also recommend after a workout if you don't have a carb drink or some food on hand. Tastes great, mixes great and digests great when your diet is on point. For me Mutant has the best mass gainer at an affordable price.

5/5
Great product, tastes great and shows results!
4.5/5
Decent stuff, mixes well and doesn't feel like you're eating powder. Definitely helps me during the day. The extra carbs help the energy levels, generally help me keep on the weight I have even though I have a high output job and tend to lose size very fast.
5/5
This is stuff is legit! I've been lifting for a while now and tried a variety of Mass Gainers, top brands and middle of the range, then also some I had never heard of! But Mutant has got to be the best out of the bunch, I've put on 8kg of mass through a balanced diet, workouts each day & 2 shakes per day over 3 weeks! Couldn't recommend it more!
5/5
Great product at a great price. Thanks to the boxing day sale.
5/5
Great product, still think mutant is number 1 product. Got gains really quickly and put on enough weight to bulk.
3/5
Be taking it for about 2 weeks now the chocolate taste ok
5/5
Great taste, good value and it really works.
2.5/5
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**
5/5
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!
3/5
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)
4/5
Decent gainer this one, gives ya made ga. Tho
3/5
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.
5/5
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.
5/5
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!
5/5
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.
4.5/5
I think they have changed the formula or at least the taste of the triple chocolate, good product but liked the old taste better.
4.5/5
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.
5/5
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.
5/5
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.
2.5/5
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 :)
2.3/5
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.
2.5/5
Update from May, now up to 88kg, working out every second day, taking BCAA with Mutant Mass two scoops after workout works for me, pre workout using C4, thanks again to your team awesome service.
2.5/5
I have been using Mutant Mass for about 4 months now, as well as working out with my home gym, have gone from 72kg to 84kg, this is a great product.
2.5/5
I have been using Mutant Mass after my swim sessions in the afternoons. I session lasts up to 2 hours. I find the blend of protein and carbs are perfect for recovery. And I'm ready to go again the next day.
