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)

Does what is says but portion too big
Definitely working for me, however...the standard serving is HUGE and way too much for me. Even splitting in half I found it bloated me up so much I was wasn't eating as much, hence defeated the object!This is what I have found best after trial and error..I personally have two shakes a day but less than half the standard amount in each.I add 350-400ml of semi skimmied milk into the shaker. Then add 100g of powder (put the milk filled shaker on some scales before adding the powder) but also a heaped teaspoon of cocoa powder. This makes a big difference to the taste as without it, the taste isn't that great (for me). Certainly not your usual chocolate milkshake taste without the extra cocoa. Doing this, there is no problem with mixing/lumps. Shaker is fine. This portion size also makes the tub last a lot longer.I have one of these after breakfast and one after dinner. This adds 1000 calories each day to my diet. Have gained several pounds in less than two weeks. Key is to keep eating as you do normally and drink this AFTER eating.Hope this helps.

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
