Not really enjoyable

I am a vegetarian for years and to expand my Eiwessquellen I know now all the protein powder from the health food store. Now I bought because of the low price of peas, rice and hemp powder on Amazon. All thing I can not tell you what tastes worse. With the products from the health food store that has nothing to do. The first two taste together as wall paint and concrete that you can not trust people with taste. The latter tastes like earth and grass.
I am of the opinion that the powders are not in order, but unfortunately a return was not possible. Although the Amazon customer service was very nice, but the stakes could not really help, because it is a marketplace-seller who was not so nice way, me. I'll stay anyway sit on the costs, but will buy after this experience in this way no more food.
