My tri-mix contains phentolamine, papave and prostaglandin. Don't know the amounts of each. I use .02 - .05 ml of tri-mix about 2 hours after I take 50 mg Viagra. It works great every time and there is no pain. Stays up for about an hour.
My first uro was only concerned that I not die from PCa. His PA was the ED expert and he had no constructive advice. Mainly he just joked about it. I think he was biased because of my age. I got a new urologist.
We all find out that we must take control of our recovery. Thanks to you here on the forum for helping me get my life back...
