I was told the gainer didn't taste good and that I should return it. It was cheap enough for me to not care so I kept it and tried it. To my surprise it was quite good but I can see why not everyone would like it. The oat flour makes the consistency a bit textured and less smooth. The flavor profile is a bit less sweet which can't really improve with less liquid to powder ratio since the thickening effect of the oat flour. Mixes fine in a blender bottle but the serving size require a LARGE bottle to mix. With a serving size of 700ml liquid to 3 and 1/3 scoop powder I picked up a 32oz bottle which was not big enough. I adjusted the ratio to 630ml to 3 scoops. Also there's only 50 servings in an 11lb bag. Effectiveness is good so far. Extra carbs in my diet has given me tons of extra energy throughout my workouts.

Felt like it is some breakfast recipe post workout.

I make a weight gainer protein shake 4 days a week that I drink during my workout on my lift days. It’s definutely a thick protein powder, but making a protein shake with almond milk, ice, & honey helps the chocolate smooth out. Happy with the fill & results for the price.

I see a lot of the negative reviews say that it is gritty and doesn't mix well, and while I tend to agree, I see it as a positive. I do feel it mixes fine, but it is certainly gritty. The grittyness is due to ground oats used as a filler, as opposed to maltodextrin like other gainers. I ordered the Hard Gainer from here as well, and I like it much less than the Impact Gainer. The Hard Gainer contains maltodextrin and no ground oats, so it is very smooth and mixes well. I miss the grittyness and real food quality that I get from the ground oats in the Impact Gainer. I took one sip of my Hard Gainer shake and logged right in to Order Impact Gainer. Plus the Impact Gainer many more calories per serving compared to the Hard Gainer.

This stuff never dissolves. It’s gritty and it’s overpowering because it’s so sweet. I couldn’t finish one serving. Complete waste of money. This stuff seriously makes me puke.

The nutrients do its job- high carbs and calories. However, I can't get over the texture/taste - It dissolves less effectively vs. the Impact Whey protein, and leaves a sludgy, grainy, stinging texture in your mouth. As for flavor- I got vanilla, and it was overpowered by the texture. A bit disappointed compared to all the other good products that MyProtein makes.

I am absolutely sorry to say that this weight gainer is NOT GOOD. I ordered 22lbs and I can simply not get it down. There are small tiny grains in the powder that simply does not dissolve. It gets stuck it your teeth and it feels like chewing on sand. And the after taste is not great either.

Macros are incredible on this for bulking or even cutting. Great way to get in quality carbs and protein while keeping fats low. Tastes pretty good. However it is thick, as expected with something with oat flour. Only weight gainer on the market worth your money.

This is the finest quality weight gainer I have ever had. Myprotein has been one of my favourite brand for the past 10 years or so. Been using this stuff for a couple of years now, just received my latest order of 10kilos of strawberry cream and I can't wait to indulge in the limitless gains contained therein. I used a 70% blend before this and I used to suffer from some nasty farts but I always thought this was to be expected when consuming whey protein. I was wrong. I now realise the previous blend wasn't especially clean and contained large amounts of lactose which was a likely factor in my horrific gainsgas. Since using this I don't suffer nearly as badly and the wife is much happier! Tastes great with milk, more than fine with water. Mixes absolutely brilliantly as long as you shake that beach hard and then leave it for a few minutes to dissolve.
