Review by Anonymous on Nov 11, 2021
I’m always a bit worried about getting shakes etc due to not liking the texture however this is actually really smooth, I have the cookies and cream flavour and with water it’s delicious. It doesn’t leave you feeling heavy afterwards. I’ve had a few mates try it and they also said it was really nice. Will definitely buy again.
