@dpayton thats exactly what I take ....two capsules a day in my morning Hot green tea.

@dpayton , thanks. I got the initial information from ecurb then started researching it. I'm taking close to 12 gm per day of the WBM powder as some of the data from the trials showed people taking up to 14 grams per day.
I'm also taking Turmeric, CBD oil and Taurine as each of those have had an effect on PC from different studies. Do searches on each of those and PC if you are interested.
I'm stage 4 with one spot on my hip bone according to the PET scan. Just finished radiation for both the prostate and hip so I hope it was all of it but taking the supplements in case there are more spots not picked up by the scan and maybe the additional stuff might kill off anything that may be floating around my body. It may be a lifelong thing taking these if my numbers stay low. Small price to pay,
Anyways, here are some links, but there's other information out there.

@dpayton I take this exact supplement and my last PSA test 18 months post radiation (didn't have surgery) was undetectable. But was it the mushroom supplement, luck or having a great medical team at a top-notch cancer center?
