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 old formula taste and mixes way better. The minute I tried this one I knew something was different. It almost has a spicy taste to it which is so weird 

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.

Didn’t check the serving size but I guess I should have expected to need to use a lot of scoops to get my protein target. The 9 scoops to get 90 grams of protein won’t fit in my blender. 

This stuff taste better than most brands I've tried BUT the texture is so unpleasant. It has a chalky feel and if you don't keep it well shaken, it will settle. If you can make it paste the chalky texture then you'll be fine. Other than that I have no complaints!!

For me personally, I'd rather mix it with milk instead of water. Helps with the texture a bit. 

This is the best gainer I've tried. I prefer it because they offer the unflavored and it doesn't seem to have a bunch of junk in it. I understand a lot of people enjoy the flavors, but personally if I'm eating(drinking) the same thing every day, I get tired/sick of the flavorings companies add. 16oz Whole milk and 100g of this stuff is a great way to get some cals in. My only complaint: It seems the nutritional facts have been changing back and forth on the labels. The bag I have lists serving size of 3 scoops(not 3 1/3), The bag I had before had the 3 1/3 serving size. Anyhow, it makes accurately measuring macros a little bit of an unknown when it keeps changing, even if only a little.

Bought the gainer blend in chocolate, seeing results after consistent consumption (consistent for me is 5 days a week). I've been taking half the recommended daily portion and I'm up 5lbs in one month (with an extremely fast metabolism). I haven't had issues with mixability like mentioned in other reviews, however, I use a Ninja Blender when making my shakes. To the 3 scoops of powder I add: 1.5c water, 1 avocado, 6 ice cubes, 1 tbsp maple syrup, 1/4 tsp cinnamon, pinch of himalayan salt (adjust water for desired thickness). Makes 2 servings of luscious smoothie that tastes like dessert! Would buy again or try the Extreme Gainer Blend.

I usually don't use weight gainer because most mess with my stomach, but I really need it for my body type. I took a chance and tried this one after enjoying the regular protein powder and im so excited to see it not mess with my stomach! I mix with almond milk and am able to have a dose before and after my workout without any issues and also seeing results! I already bought another pack, highly recommend!

I got the chocolate smooth and it tastes AMAZING! It doesn’t blend properly so it’s a little grainy but it’s not chunky like protein powder, I don’t mind it at all. 100g is too much at once for me so I take it twice a day (once post-workout and once before bed) with 50g and 10oz of milk. I would highly recommend!

10oz of milk/50g

To me it's not the taste, it's more the texture. Don't get me wrong it's still gross but texture wise it's like mixing flour with water. I usually try to mix it into a fruit smoothie with either bananas or pineapples. That's all that I've found to work. They also have to be fresh!! Frozen fruit works too but no where near as well. Also if I'm feeling lazy, I'll just add it to apple juice, which I know defeats the point of no sugar but it works better than water or milk.
