MASSE MUTANTE, 15 lb

He says I’m too skinny, but I really do love it. I use it between meals to help increase my calorie intake.

It was delicious. Ordered both the fudge and milk n cookies flavours and they both rock. Will see how the caloric and protein content fares in a few months but the taste is truly great so it’s fun to enjoy!

The taste is pretty good, and it mixes very well. At the price at which I got it, it definitely makes it worth it!

Fast shipping and good service.

Mutant is always my go to and has been for years

I have been using Mutant Mass for a few years now and was happy to find that it is Canadian and I am glad to continue to support Canadian. I like it because it doesn't have the usual protein flavor and tastes more like a chocolate smoothie. It even makes a great Hot Chocolate mix!

Purchased the chocolate fudge brownie mass gainer... Was really surprised how tasty it was....
This product is handy. If you need to eat 4 thousand or more calories a day, it can get rough trying to meal plan and eat that much. It can me so tiring continually eating...
At least this takes a meal out of the mix...
Works well, tastes great. Would buy again!

Tastes great! Mixes easily

i’ve tried almost all the flavours, aside from chocolate and they all taste pretty good. they mask the usual protein flavour a good amount, and when vanilla can be mixed with other things to make it more variable. I usually drink 4 scoops 4 days a week and 2 scoops 2. it seems to last about 3-4 months for 2 bags. only downside is it can be a bit nauseating, though that might just be a me issue.

Love the strawberry one, very smooth and dissolves completely

Pretty good, Only took half the servings but it's pretty filling.

I’ve used Supplement Source for some time now and it never disappoints. I always get great deals and I like that they always throw in some freebies for me. Lee up the good job. Chris

Been taking this mass gainer 3 years now and it never disappoints.

Tastes great. Helps to supplement nutritional goals. I was able to gain 25 pounds of lean mass over a year and a half after I found mutant mass.

It’s got all the makings of being a great gainer but it’s just too hard on my stomach, I have found if I only do one scoop once a day I can handle it. Other gainers I would do 2 scoops 2-3 times a day.

Superb gainer, not too sweet, not full of sugar, great mixability, includes most gain supps also! Only gainer I've been using for a while and wouldn't go back!

Awesome 💪 I like it so good

The customer service was amazing

I ordered this mainly for my Fiance which he loves it! havent been on a mass gainer for years and just got back into the swing of it. I used to work for a supplement company so i have had my fair share of protein testers and mutant mass stood out not only for quality but for taste
Every now and then i steal a scoop because it is so yummy
