@paulsweeney Thank you Paul. I didn't realize I posted it twice, as my first comment was "under review". Have you read the book "Fight Cancer Like a Man" by Dr. Stephen Petteruti? He has an entire chapter on repurposed drugs for prostate cancer. I'm in the process of reviewing them now, but the list he includes in his book is as follows: Sirolimus, Metformin, Low-Dose Naltrexone (LDN), Doxycycline, Atorvastatin, Ivermectin, Menbendazole, Mistletoe (Viscum), and Itraconazole. He explains what they are and why he recommends them. He has an entire other chapter regarding "supplements", which I will focus on after researching the repurposed drug suggestions. He also has a YouTube channel called "Intellectual Medicine". There are many videos on that channel that include information that is worth contemplating. Thank you so much for all your work on this.
