Not sweet if you are someone who like tasty things though for me i don't use sugar so i prefer the taste cause before i was using other brand and i had to really dilute to reduce the sweetness, just received it today so lets see if it does what is written

Vanilla tastes awful
I bought the vanilla flavor and it’s one of the worse mass gainers I have drank, the after taste is very bad makes me gag. I have the full bottle and I can’t even return it

Works well for what it is
I bought this mass gainer two months so I can gain weight and put on muscle mass. Let me tell you it worksssss! Over the two months I’ve been taking it I’ve noticed noticeable size gains across my entire body. Though one thing if you were to take this and not train with intensity you’ll gain fat but me since I train five days a week with high intensity per session this mass gainer works very well as my post workout shake and helped significantly to put on muscle mass as well.

With weight training and a very physical job I need a ton of calories (around 4000 a day) this mass gainer definitely helps, I find it tastes better with semi skimmed milk than water, and totals more calories consumed with 2 servings. The scoop is quite bigger, larger than what you'd used you put detergent in your washing machine, and the dose is 2 a day, you could just have one after a workout, but I have one at work around 10-11am which helps feel a gap well and being a shame is easier than food or snacks. I got the vanilla one, it tastes a tad different to the normal whey protein by ON, sweeter maybe but after a first few tries it's fairly nice, I don't use a blender just a shaker ball, and about 600ml of milk, it does a clump a bit and needs several shakes between a few swigs. Put the milk or water in first (this is common knowledge) but try and shake it hard/drink quick after dropping the powder in as the longer it fits the more it'll clump at the bottom and it's not fun trying to consume the gloop at the bottom, messy. Or just don't be lazy like my and blend it, might come out better.
