This weight gainer is perfect for bulking up. It may not mix the best, but it’s amazing for calories and protein. If you’re a skinny guy looking to bulk up, this is the right one for you! (Buy the unflavored one)

I recently bought this blend because I wanted to try something new. My first experience with it wasn't great at all. I tried shaking it in a bottle, blending it with ample water, and even trying to let it sit for a couple hours but it did not mix or dissolve whatsoever. I can't stand drinking it because it feels like trying to drink wet sand.

Tastes like medicine. One of the worst protein flavors I have ever had. Should have read the reviews before buying. 

To preface, I purchased the Strawberry Cream flavor, so you may see different results with unflavored or chocolate. This gainer blend reminisces of medicine. The strawberry flavour is extremely artificial and even smells like chemicals. I first mixed this with water, which didn't work whatsoever. A layer of sandy residue would not mix into the drink. Next, I tried to blend it into a smoothie with frozen berries and milk. The sandy texture was still present. Drinking this flavor made me extremely nautious, and followed with a stomach ache. The "chemically" taste left a burning sensation in my throat, which may be a result of rapid caloric consumption or just the artificial flavour. Even smelling the powder makes me nautious. I would without a doubt stay away from strawberry. Im hesitant to try any other gainer from myprotein because I'm sure it will be similar to this. Go with a protein + oat shake instead. If you need the calories, add some oil. It'll taste infinitely better than this, and without a doubt be healthier. I would avoid this at all costs.

Tastes ok, but does not seem to mix very well and leaves a grainy sludge at the bottom

I got the unflavored version after reading a few bad reviews regarding the taste of the flavored powders. Nutrition-wise, it gets the job done and helps pack a good amount of calories. The texture is a bit grainy and the powder isn’t super easy to mix. Taste is pretty bad but you shouldn’t buy it if you’re worried about the flavor. It kind of resembles an unflavored oatmeal. All in all, this blend does what it’s supposed to. 

I was struggling to stay over 150 (I'm 5'9") even while eating a couple extra meals a day. I switched to this stuff from the pure protein and I gained 7 pounds in the first week. Never tried flavored because I don't like those types of sweeteners. I just add a tiny bit of chocolate milk to whole milk with two scoops. Gets a little chunky at the end but it gets the job done. No issues with flavor. I actually like it.

I have been going to the gym for a long time now and I always have a protein shake after my workout. So I’ve had a fair share of protein powders. This is by far the worst protein powder I’ve ever bought. The vanilla flavor is super overpowering and very fake tasting. It’s also super gritty which makes it hard to put down. I do not recommend getting this unless you don’t have taste buds!

Personally, I think the vanilla flavoring is waaay too prominent for my taste. My smoothie consists of: 1/2 cup oats 1/2 cup berries 2 spoonfuls of greek yogurt 1/2 cup milk some water and a few ice cubes, but after pouring in only 2 scoops, (the default serving is 3 scoops of powder) the vanilla flavoring SEVERELY overwhelmed all the other flavors in the drink for my taste. I couldn't even finish my smoothie due to how strong the vanilla flavor was lol Unless you're a vanilla-fanatic, I'd recommend going with the unflavored powder. I hope this helps someone.

Maybe mix with chocolate protein powder or flavoring. A 1:2 vanilla to chocolate scoop ratio should be fine.

The strawberry cream flavor is horrible. It is cloyingly sweet and very artificial-tasting. I don't understand the need to megadose on Splenda; it's revolting. Go with the chocolate smooth flavor--much more palatable. Product mixes surprisingly well with water in a 24 oz shaker but you have to give it a minute for the oat flour to absorb the water and gelatinize. Functionally the product gets the job done as a mass builder but you may need to use more scoops than you think. Also great for long-haul road trips.
