My go-to shake and the best tasting I’ve tried
This has become my go-to shake. I’ve tried quite a few meal replacement and protein shakes over the last year, and this is easily the best tasting one I’ve found. I’ve been using it consistently for over 8 months now. I feel full after having it, and it’s fitted really well into my routine alongside regular exercise. I’ve lost over 3 stone during that time, and this has helped me stay consistent and make healthier choices overall. I’ve also found it helps with recovery after gym sessions. I usually mix it with ice, which gives it a really good consistency and keeps it nice and cold, exactly how I like it. It blends well and doesn’t end up thick or gritty. I’ve tried a few other flavours in the range too, but the vanilla is my favourite. It tastes much more natural than a lot of vanilla shakes on the market, which can be overly sweet or artificial. The only small downside is that the scoop can be a bit tricky to find when first opening a new tub, so I tend to keep one from the previous container. Other than that, I can’t fault it and will continue using it.

Tastes like vanilla and strawberry is nice, but not 100% Keto friendly
Just tried it today as I am going Keto agan, but this isn't Keto. It tasted okay, however (TMI) I had a bowel movement after wards, so jury is out, not sure its good for my gut condition and IBS. I have ordered the strawberry one. Really a shame Exante aren't doing shakes anymore, as their vanilla Keto was the best. This tastes similar to Exante one, but it's protein. As a meal replacement to get me back onto fasting in general before I do Keto eating, this is a good solution. Has nutrients I need and saves time. WIll do an update later. UPDATE: Srawberry one is really nice.

Tasty and thick
So I started the strawberry one today, made with semi skimmed milk which i will be changing to skimmed milk when I've been shopping, wished it up and it tastes lovely, really thick, only used one scoop,its obviously too early to tell if its aiding weigh loss, only time will tell. The only thing I would say is, the tub is far too big, surely could have user a smaller tub as its only half full lol.

Does what it says on the tin
Smells a bit mad, but tastes as good as any of these things can. Thicker than expected when mixed, but in a way that feels like it helps the drink to be filling. Am on my first day with it, had it for breakfast at 9am. It's 2pm and I'm still full and not thinking of lunch. Seems to be working. It mixed very well in a shaker bottle, no lumps. Pleased with this purchase.

Detailed review
I was using a meal replacement shake from a brand that was supposedly the best (Protein World) and found the shakes had poor mix ability, were chalky, oaty, left a bitter aftertaste and eventually made me feel sick. I decided to give this ago. First of all the tub is unnecessarily large making it difficult to store if you are short on space. I ordered the chocolate flavour and I mix it with 400ml of water. It has great mixability and no powdery lumps are left. It doesn't smell strong and if you leave it in the fridge or standing for a few hours it does become a lovely thick very smooth texture. The taste is subtle I would like it to be more chocolatey but it isn't bad by any means. It does have a faint chemically taste but it doesn't really turn me off. It isn't chalky, doesn't make me feel sick or leave an aftertaste which is a huge improvement on some brands I have tried. However, for me I don't find it keeps me full long enough. I have a high protein breakfast and this shake for my lunch. I drink the shake around 12.30 - 1pm. It fills me up and satisfies me at the time. However by 4pm, I am starving and by the time I get home from work at 5.30pm I feel sick with hunger. The first time I was shaking I was so weak. It only fills you up for around 3/4hrs or so. If you are going to use this to replace your lunch perhaps have it as a later breakfast followed by a healthy lunch or if you do use it to replace your lunch you will also need a healthy, high protein snack to keep you going until you have your evening meal. One other thing I would like to note is that I am not sure if this shake agrees with my stomach. Last week I drank it for 2 days and had stomach ache all weekend. I had to leave work. I put it down to a stomach bug as it was going around. I tried the shake again and the stomach ache returned. I am trying to pinpoint if this shake is the cause of it. It's a great price point, and has the best texture I have come across. Taste is pretty good. I would probably get sick of it everyday so I have soup to get some variety. If this shake gets me fuller and more satisfied for longer I would give 5*. I am not sure if I will re-order it depends how I go with this one. If I find one that's more satisfying I'd probably switch. Not a bad shake but could be better. USN please reduce your packaging the huge tubs are not necessary.

Guter Mahlzeitersatz, da dieser Shake Balaststoffe enthält. Der Shake löst sich gut auf und die Geschmacksrichtungen Banana Caramel und Vanilla Cream sind sehr lecker.

J'utilise ce produit depuis 4 mois. Je remplace un repas par jour et je mange les autres repas équilibré. Avec un peu d'exercice cardio, j'ai perdu 7 kg dans 2 mois et en 4 mois, j'ai déjà perdu 9.5 kg. Le produit ne me laisse pas faim et le gout est agréable.
