“I love this. It’s tasty and not too sweet. Gives me that desperately needed chocolate taste whilst dieting and a good portion of my protein requirements. I replaced breakfast and lunch with a shake and ate a healthy meal for tea and lost half a stone in a couple weeks. If I’m a bit hungry and need extra carbs I throw some porridge oats into the blender. Sometimes I’ll blend in an egg or a banana. So easy as a meal replacement if you don’t have much time.”
Yes, I recommend this product.
