I ordered 2 of these bottles, which were also delivered very quickly. This has certainly worked very well. I can, however, make any statements about the effect of the bottle's contents. The taste is awful, but something like this is well known, "matter of taste". I have not taken off in just under 2 weeks on time anyway. The feel-good aspect is in my opinion only a matter of faith. So all in all I had the money can also save me, then I probably would have pleased me more. But maybe you have the juice indeed only take much longer and invest more, then at least the dealer has a positive "sense of achievement".
