Understand your fear and worry in your post. Any Gleason 9 situation is serious, but it doesn't mean its hopeless by any means. So he had his surgery, then you did radiation as a precaution. This would be a good approach for most men with his stats. Two years after surgery, his PSA is back to .1. Yes, it is low so to speak. What most would suggest is probably to go to Hormone Treatments. There are several people here first hand experienced with using them. They will starve out the remaining PC cells and slow things down. The dietary changes and supplements are good things for general health reasons, but there's no proof they can slow down or stop cancer growth. Nothing wrong with doing that though.
Hopefully someone well veresed with hormone therapy will come along and give you some better advice. I wish you luck, and please keep us posted closely.
