I’ve used this protein for years but I recently ordered the Mars one and have found my new favourite! It mixes really well and it’s the first flavour I’ve ever enjoyed with just water. I wouldn’t say it tastes like a mars bar but it still tastes good. Well impressed!

抹茶ラテめちゃくちゃ美味しいです！ほうじ茶は試しましたがお勧めしません(´-`;)
I loved Matcha Latte flavour so much that I regretted not buying more.
So, I tried Hojicha this time. I can taste the unique smoky flavour Hojicha has but it’s too sweet and tastes somehow little off.
It’s not bad but not good enough to motivate me to buy again.

First time order 🙂
Perviously got some of this from boots in town in a smaller tub.
I love the flavour so looked for a bigger tub and here I am writing this review. Buying it here works out much better value including the next day postage to my front door. Excellent experience 🙂

I ordered the chocolate brownie flavor and it’s hands down one of the best flavors of protein powder I’ve had so far. The solubility is also much better compared to the Essential ones.

Bought this because my gym progress was flatter than a pub pint left out overnight. Two weeks later I’m walking around like a divorced dad who just discovered dead lifts and emotional unavailability. Mixes surprisingly well too…….no weird lumpy goblin paste at the bottom of the shaker. The chocolate peanut butter is a Smooth flavour, which is worrying because now I’m having protein shakes for dessert like some kind of lactose-fuelled meathead. For the price, honestly hard to complain. Up to 23g protein per serving, low sugar, low fat, and enough flavours to confuse a Victorian child.Would absolutely buy again.

Low carb protein powder compared to other available brands in the world without many additives. I have tried many flavours from myprotein but chocolate smooth is the best one till date. I will always order the same from now on.

The Mars flavour is just awesome! Mixes very well, accurate flavour & no artificial after taste! By FAR the best protein flavour I’ve ever tried (& I’ve tried a fair few).
Highly recommend, especially for overnight oats!
