Tasting the Recovery XS Shake

I forgot to mention last night but I made my first shake after the fitness test.
I followed the instructions and made it with 400ml of water.
I ordered the shaker bottle which comes with a metal wire ball to help mix it. It did seem to mix it well, but I did find the taste chalky and powdery. I'll have to see what other people mix it with.
It will be interesting to see if it works.
