Absolutely unbearable !!!

Since I participate currently in a fitness program, should I take the evening Caseinshakes or -Puddings to me.
I ordered the casein in "Cookies & Cream" and unfortunately have to say that it is the most disgusting powder that I have ever tried.
Not only taste absolutely disappointing, but also in consistency disaster: despite stirring, shaking and Shaken remain small crumbs in the ground that are simply inedible.
It tastes almost as if the powder is so old that it is no longer resolves correctly.

All in all: stay away !!!!
