IP-6 just came on to my radar screen recently. Surprising since I frequent several PCa websites. I am 7 1/2 years out from DaVinci and started seeing a psa rise 18 months ago when I got a .05. It has risen slowly over that period to 0.11. Now facing the reality that SRT may be in my near future.
I am throwing everything I can find at the beast in an effort to put off radiation as long as possible. So IP-6 has been added to my arsenal after researching it prettty closely. Next psa test in March will be crucial in my decision.
Here's hoping I can report good news.
