Can't actually help with your comparison but please can you help me as I am wanting to get the RAAX11 to help my husband who has advanced lung cancer. He has for a year and a half taken RF1000 agaricus and I feel it has helped as originally he was told he had only three months to live. However, my supplier in the USA has stopped and it is frightfully expensive from Europe. Good luck with your info and if you get to hear that RAAX12 has benefits over the other one I'd also like to know.
