I’ve been using this for a while and I’ve gained so much more weight in the gym. I is easy to mix with other flavours which has made drinking my shakes more enjoyable.

I saw the reviews now I know why partly its got took be the best tasting protein drink I have ever had. I got the vanilla cream 2x tubs of it it's not thick so doesn't make you feel gaggy, if anything sometimes it's sweet and tastes like milky bar from KFC 2ndly I've tasted it now I will see if it works will edit and update soon

I've been a user for a while now and product does what it says

I'm pretty fussy when it comes to Protein Shakes.This one however, for a mass gain shake is surprisingly tasty.I tend to make it in the morning, chuck it in the fridge and then drink it in the evening... keeps it smooth, no bits and tastes good cold.I recommend this as a mass gainer shake.

Though received as described , too me time to get use to the taste and smell. But a good size for money.

Only recently started going gym with a buddy from work and he recommended this to me and I'm Already seeing results and tastes nice with milk instead of water. I'm a bit of smaller build so I have to have to half the dosage as I was getting stomach issues but have now gone since lowering my dose... Maybe I'll try vanilla next

Where to start, so I ordered the 2.5kg tub a week ago. I'm just using this to put weight on, I currently am 6'2 and weigh in at 10st, so I look pretty thin all the time.I started by making the shakes with water, as I thought that would be the worst tasting version, I use a big jug and a stick blender to make it. I have had other powders and protein shakes in the past which haven't mixed as well, but this powder is very soluble and there is no nasty clumps.Making it with water is ok, but it tastes like yahzoo milkshakes (that kind of plastic taste you get from them) but by the third day I'd got used to that.When made the shakes with water I found that the shake made me feel quite bloated, a 710ml serving makes up just short of 1 ½ pints, and I'd find the last ½ pint a struggle.So i bought whole milk from the shops so I could make up this shake with milk instead. Again the powder was very soluble in milk and required a quick 20 second blast with the stick blender to mix it up.This made a massive difference, it tasted like a McDonald's chocolate milkshake just not as sweet and less thick. I didn't feel any bloating at all, and could of easily had a second serving straight after. From the calorie count on the back, using whole milk puts a shake at around 1700 calories each. So from now on I'm going to be making it with milk and only make it with water in a pinch.Weight wise I found other powders didn't really show me any difference, I didn't feel any different either. However I've only been on this shake for a week and I've already felt a difference, i feel better, and I have put on 5kg already. So I'll be sticking with this powder for the foreseeable.A small note about making it with water.... I made a shake with water and 2 tbsp of smooth peanut butter and that was much better in taste, but the bloating was still a problem
