Recommended

Fantastic protein, tried lots of types due to sensitive stomach and this is prefect. Great flavour great quality

The taste is good, but does not mix well

The price/quality ratio is good, good macros, soft chocolaty taste, which I liked. However, mixing this powder is a nightmare. It gets lumpy or forms a single giant ball and my mixer literally struggles to work trying to blend it. Which is why, overall, I would not recommend it.

Very Sweet!

Great price, but the taste is very sweet, even for me and I have a huge sweet tooth! Still though, high protein content and mixed well!

Disappointed

I'm not keen to be honest. The shake tastes very gritty and floury and the banana flavour tastes very artificial. It's a reasonable price for 72 servings and offers up good protein but once it's finished I wouldn't buy again.

High quality whey-mixes well and no stomach issues

I've been using this whey protein for about 3 weeks now, mainly post-workout. The mango and passion fruit flavour is smooth and not overly sweet, which I appreciate. It mixes easily with water in a shaker or milk no lumps, no gritty texture. What I really noticed is how it helps with recovery. I train 4–5 times per week and usually feel sore the next day, but since using this protein, muscle fatigue is reduced. Highly recommend it if you're looking for a clean and reliable post-workout shake.

Decent but too grainy

Tastes like Kinder Bueno? No

Tastes like hazelnut? Yes

The shake is very grainy and the sweetness is good. It has like a vanilla hazelnut taste to it. It tastes like any other protein shake. It has a slight wafer aftertaste. I think the protein content is good. Easy to use, just mix with water or milk. The value, you can probably get cheaper options but if you want this taste, its a decent price for the amount of protein too. Not too sure if it mixes well for me it was very grainy.

Best for low carb users

A little bit pricey but a great product . One of the few which is good for low carb diet while still providing the right proteins for muscle build recovery

Delicous and big

Amazing taste, doesn't mix as well as non iso-xp

This powder smells like custard vape juice which was off putting, but the taste is anything but. Absolutely delicious.

The one issue is this powder forms one giant clump when added to milk before mixing clump free with some slight separation. Tastes smooth, just looks odd. This is in stark contrast to the non isolate whey from this company which mixes easier than I have ever seen from a protein.

Surprising given this is supposed to be the isolate!

Good!

But I wouldn't buy it again. They are usually sweet but this one is too much for me. Good price for the quantity if you don't mind the extra sugar.
