Mutant – The Original Mass (Strawberry Banana) I originally ordered this because of a recommendation of one of my favorite people to talk with and a member of the team (Alicia.) I was trying to find and also compare a product Muscletech – Masstech Extreme gainer 2000 due to two very important factors 1. The Masstech has limited flavors (Only 3 and now two with the purging of the Strawberry flavor) 2. the 22lbs buckets are hell to open.) there was only one time I got the 22lbs. (easy open bucket) but was told that was a fluke I was trying to find a product with more flavors and NOT trying to do a workout before my workout LMAO In comparison to everything this was number 2 in calorie output and flavors The strawberry-banana palate taste is kind of dissatisfying due to you can’t taste the strawberry at all. It really reminds me of the old-fashioned Banana flavored Quaker Oats, Not bad but not Strawberry-Banana. In my opinion, the consistency is way too sweet and sticks to everything if you're not careful. This is a very dense product make sure you have enough liquid otherwise it will coagulate very rapidly. Because of this, I have 100% stopped using this as a shake, rather I am now putting it in other foods, Oatmeal, cookies and slipping it in where the sweetness can come out. Overall this is a great alternative to the Mass gainer but nowhere near the overall benefit. I have since stopped using this product but I do recommend it and will use it again if need be. Overall Taste value: 7.1 out of 10 Price: 8.2 out of 10 Different Favors: 7.0 out of 10 Will Buy again (MAYBE, if need be) 7.5 out of 10 Will recommend this product (YES) Overall Rating 7.3 but believe me, this is only the math and my opinion… Side note: Again, please exercise enough liquids when mixing or the consistency won’t be good or taste good.

My God! this **** is the real... ****. I'm sorry but this Mutant Mass will really give additional mass... crap mass at the toilet. It's like I eat some chimichangas or something.

I have been working out for about 2 months now and used this from day 1. i did an extreme weight loss before and lost muscle unfortunately and with it came the problem of reaching calorie surplus even maintenance without puking and feeling bad. This product has given me the extra calories for me to surpass the maintenance and i really like the new formula. The relative low sugars for the calorie gain is defintently worth it even though you will go around with gases for a while. Gaines are happening and will keep using this product.

This product works very well for me now. I to had to overcome the bloating and the vomiting feeling. I asked around and found through many knowledgeable people on how to take mass gainers properly. I wait until an hour before i go to bed and i stopped eating gassy veggies and starchy foods. I have about 3 hours of no snacks prior to drinking it. I do mix it with a ninja blender 600ml and 4 scoops

The strawberry banana crepe was discontinued after I bought it, I don’t know why but this is easily the best flavour out of the three I’ve tried. It tastes a lot like wrigleys fruit chewing gum.

This is a great weight gainer if you don't use it how they suggest. Like others I think 4 scoops is way to much at one time (fills 80% of a blender bottle). In a normal sized blender bottle I mix 1-2 scoops with either all water, of half milk half water. Some water is needed to make sure it mixes well if you do this, this is one of the best protein shakes I've had. I have gotten the 15 lb bag of strawberry banana twice, and am about to order a third, but these bags last me a lot longer than the "serving" size suggest, which is 24 if you have one a day. Usually last me 2+ months, I eat about 2,000-2,500 calories a day and drinking 2 scoops of this with working out has allowed me to gain good weight, not crazy fast but I am very pleased with how it's worked for me.

The worst gainer I've ever had. I have never reviewed a product in such a negative way but it's justified. When I bought it the price was great, even when you have 38 grams sugar per serving. The taste is not bad, could be better but I'm not planning to.wait.for improvements. The first time I took it I I was in the bathroom for an hour. Generally my stomach get used to this after the second time, third maximum. But with this one every time is like the first time ( but not romantic). The only mutant mass I see is on the toilet. And you can bet on what.the say " leave humanity behind" well... BB, I did it no human goes to the bathroom like I do...

This mass gainer is one of the best out there in my opinion. The taste of cookies and cream with water is actually okay and it goes down very fast. I prefer water over milk at all tine so thats perfect. The aftertaste can however be debated but ocerall it is a good one. Def recommended :)

Love the product, great tasting goes down easy. As Alot of you will know putting on weight is about calories. To gain weight you must eat surplus of what your body needs. So anything that puts you over you daily calorie intake is going to make you gain weight. So spending this much on shakes when you could just sort a good diet seems mad. But for someone who finds it hard to eat that much in a day this is the answer. I need to eat roughly 4000 calories for my metabolism and training schedule and I can't eat for ****. So just 2 shakes a day at 4 scoops a shake mixed with milk. Is me 3 quarters of the way through my daily intake. Takes away half the battle for me and I'm in the best shape of my life.

The flavor took me a little bit before I started to like it. Worked great though, packed on 20lbs which is saying A LOT. Weighed 125lbs for years and now I weigh 145. Shipping was ridiculously fast!! Took only 2 days to get to me and they gave me a bunch of free stuff as well. Awesome site.
