With milk it GAINS;) my approval
First shake I've tried and is lovely with milk, I have one heaped scoop with blue milk maybe 2 times a day if needed.I ran out of milk and tried it with water and is ( to me ) rancid. Something about adding water leaves a weird taste that's not present when made with milk.So for me, a thicker milk shake and never a water shake.But taste with milk is spot on.Only been drinking for a week or so but I'm sure it's adding weight (with little training)

Tasty and it works
This is the best mass gainer i have tried, it tastes good, but better with milk. The only issue is that the scoops required are quite big thus you wont get too many shakes out of the tub

Taste is amazing
It's the best tasting and I have tried alot. Mixes well and has a smooth texture without bits. 1 of these in the morning keeps me going in a busy work place until mealtime at home

Brilliant
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
