I have had a similar experience... a few years ago when I first tried it I think 4 or 5 years I was amazed at the immediate powerfull effect that then dwindled and almost seemed to wind up doing no good or even harm...SO after a few months I stopped. I only used it when I needed a boost. Then this year I tried it again and had those great results again...then they dwindled...then it got worse. I think it had to do with mixing the urine with food...all I can figure. I just started trying the topical application we'll see how it goes.
