I noticed in the other gou teng thread, people here really didn't react on the thread. In this one, nobody seems to react either. Not that people have to react, but as nobody reacts I get the feeling people here are very sceptical about gou teng. However, my personal point of view is that this is the best thing available that you can buy over the shelves and try on your own. This is an agent that was already tested on 115 PD patients and seemed to be succesfull. Other independent studies with 1 and 3 patients also showed the same benefits. On cultures and fruit flies it was discovered that a substance in gou teng clears the supposed protein causing PD. I am really considering this agent but the low response of everyone here on gou teng scares me a bit for doing that.
