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

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

Very nice
Normally with shakes I use milk so tried milk first of with this product and was very thick, clumpy and found it very sickly. So since then Iv been doing it with water and it’s a lot nicer, mixes well and far less sickly so would recommend doing it that way 👍 all in all happy with the product and after trying several different weigh gains off amazon I would recommend this one

Great flavour
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.

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

Best shake yet (except for chocolate flavour)
[BANANA] Aside from gaining weight I also use this for meal replacement. The flavour profile is superb, really does taste like a banana shake very similar to a well known fast food outlet. Mixed with semi skimmed milk allows me to replace breakfast as I struggle with apetite in the mornings. I have tried a few brands but this one wins hands down so far. Delivers a decent amount of calories to be added to your daily count and keeps you full for longer. I am not building or training just simply needing gains. A couple of weeks use has got me up a trouser size so far without mixing any additional fresh fruits or oats. I would recommend this product.[CHOCOLATE] Had high hopes for flavour on this one as a fan of the banana variety. Was disappointed, although I've had worse it is one of the better tasting chocolate shakes but still a pretty unnatural taste. Given it's synthetic and full of additives but shake flavours are improving as years go on, unfortunately for this it hasn't moved forward like others. As previously mentioned it definitely brings serious mass. The biggest problem with the chocolate flavour is IT DOES NOT BLEND WELL. I mix all my shakes in the same blender, banana flavour same brand no problem, 20 seconds gives no lumps, nice and smooth... easy to drink. This flavour leaves lumps even when blended for 60 seconds. As I can only rate one flavour per review as it's the same product page chocolate gets a 3.5 out of 5.

Smooth and Tasty!
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.
