Smooth, Delicious & Nutritious

I've never been able to drink protein shakes before because I've not enjoyed the taste or consistency but WOW! Nutrein has converted me. The watermelon flavour of their FCUS shake is delicious, and I'd enjoy even without all the amazing health benefits- they're just a huge bonus. The Nutrein protein shaker mixes the powder perfectly too. 10/10 recommend.
Thank you Nutrein!

Really Lovely!

This tastes lovely, easy to drink and a great pre-work out!

What a flavour!
