I will answer my experience. In Dec 2020 my wife was diagnosed with a GBM. They gave her 6-10 months to live. I was devastated. She was 67 and healthy with no other issues. My immediate thought was I had to do everything in my power to give her more time. I ran across the Joe Tippins protocol and immediately started the fenben. My wife was on it almost 4 years until her death. We also had 5 surgeries, chemo, radiation, a chemo drug, and she went through an ultrasound trial. The GBM very seldom loses. A couple of points. I was willing to try anything with a terminal diagnosis. While my wife did not experience any other side effects, it also did not stop the cancer. By stopping any other side effects I mean nothing visible. She had so many side effects including a septic infection that were all contributed to her other drugs. She had the best Dr's available at Barrow Neurological center in Phoenix. My conclusion is while I think some of these drugs or supplements might have some benefit for a percentage of the population, they have not been proven to be effective and may in fact be detrimental to a certain portion of the population. I felt I had nothing to lose. Prostate cancer is not that disease. The only thing I can say for sure is she did not die from parasites.
