Protein doesn't mix well, at best it's frothy which just makes it harder to drink. The only way to drink it is to chug it and the froth doesn't help. I've order tons of protein and this is the worst tasting one I've ever had (chocolate) and it has a chemically aftertaste. Literally having to brush my teeth immediately after use. Tried mixing and blending into smoothies to cover the taste using milk, peanut butter etc and it doesn't help at all, just ruins the rest of the ingredients. Really really disappointed. Struggled with whether or not to leave a review but hopefully it helps someone else spending their money on a really awful tasting protein powder like I did.

I bought this in the chocolate flavour about two weeks ago and must say I am extremely disappointed with the product. I previously used whey protein from a different brand, and in comparison this product does not mix well (and foams), tastes like cardboard, and worst of all it gives me a terrible night's sleep: I wake up with a swollen face and sore throat, despite that I have never had any signs of lactose intolerance before - in fact, I have a lot of dairy in my diet. I cannot comment on effectiveness in terms of muscle recovery as I have only used it twice.

A bit chalky when mixed but fine  and good value

This protein tastes great " Strawberry " version. But the huge letdown is the unbelievable foam forming when shaking .

I got the vanilla flavour, it tastes nice, doesn't seem to mix very well, still quite grainy but I've not used Casein before so maybe this is the norm. Morning after a heavy workout it does seem to help repair muscles faster.

I'm using in combination with a carb heavy shake for directly after workouts, The Whey for boost in protein intake each day, Creatine Monohydrate 30 mins before a workout and once a day on rest day (3g), then this Casein 30 mins before bed. Seeing results in improved recovery, too early to tell on size and strength gains.

Never really enjoyed it as a shake due to the fact it foamed up lots in a shaker. Then played about a bit by only adding a small amount of water (50ml) and mixing it to a thick paste consistency....unreal tastes and looks just like angel delight!! I now look forward to it as a treat and not a foamy struggle. 👍

Small amount of water and mix to a paste. Just like angel delight

Great product I have this before bed.

I have this with chocolate almond milk just to get the taste a bit nicer 

Very tasty and effective. I sleep alot better using this form of protein rather than whey. Easy to mix and I only use water in my drinks.

I love the casein protein as it tastes amazing but also keeps me fuller for longer!

I'm a beginner to the whole protein thing. So far I have tried Diet Whey from another provider - nice and thick and mixed week with other bits for a great smoothie. Impact Whey from MyProtein - more of a thin milk consistency which mixes well and tastes nice. Both powders are nice and sort of dense. This Casein powder is different - it is more like a very fine talcum powder, slightly chalky and the slightest squeeze of the bag can disrupt it. It can get everywhere if you're not careful! The drink itself - mixes well and tastes ok. Although I have only tried the strawberry flavour and it may be a little weak on flavour. It feels a bit chalky when drinking. The main thing I've noticed is that it doesn't start mixed for long. I thought I'd shake one up and leave it in the fridge for a while to chill. Within a few minutes it had begun to separate with a thick froth on top. This can also happen within a minute or so after shaking and when drunk the froth stays thick and separated. So... Drink it straight away or re shake. I'm guessing the more foamy consistency is different to the others because it's a different type of protein with a different purpose and use. I tried with milk to see if it was any different - not really. I will order it again but maybe a different flavour.

Water or milk.
