This stuff doesn't have clear directions on can. Does not state how many ounces of water or juice to use. I am supposed to use 10 scoops per what? Doesn't say. It tastes horrendous in water, it does tastes better in juice. I cannot tell a difference in energy at all after 1 week of use. It would be so much better in pill form. The taste of it nauseates me. Yuk! Oh well, I guess it's supposed to taste like medicine. I wish they had some samples before I purchased 4 containers of this stuff. Any suggestions?
