Ok, I know theres like a million posts on milk thistle, but i have some specific questions. I'm currently shooting 100mg of fina ed, and do indeed feel my kidneys hating me. I know some people say its the "back pump", but i disagree. After reading awhile and talking to some to other juicers it sounds like i need milk thistle, and/or cranberry extract. My question is about doseage, one post I read on a diff site claimed if I take too much milk thistle it will clean the fina out of my system completely!! I don't know if this is true but I'd sure like to avoid it. So I came here to ask the experts, what doseage is appropriate for my cycle? Milk thistle, cranberry extract, or both?? Any response would be greatly appreciated.
