Aimzee, you gotaa remember that like everything else, you will usually hear only the negative or worse side of things here, as the people who have no trouble with a pill, procedure or treatment tend to move on and not hang around discussing problems they don't have. so the results here are skewed, I think. There are side effect, to be sure, but notice that every response here described them as negative, and no one responded that they didn't get the side effects. I am sure there are just as many or more guys who can report no problem and praise it as a miracle. It's just that they aren't here reading....
I would suggest, if you haven't already, that he ask the doc for samples of all 3 of the pills and try them all. Usually, one will be tolerable. The Muse is a different category. You insert the semi-solid gel pill into the penis, using a little straw like device inserted down the urethra. Most guys report the same side effects of the Caverject (straight Alprostadil)- the aching, pain, etc. That's the same ingredient used in Trimix, and the ingredient not used in Bimix. If the 3 ed pills don't produce results, don't get discouraged. Healing and recovery takes time, and you may not see results for another year or more. In the meantime, penile therepy is recommended daily, using the pills, and a pump. I don't know how far along he is in the process, but at 2 to 3 months, he should be talking to his doc about
getting a pump, and maybe beginning the injections. The injections are usually painless and can usually produce 'like old times' results early in the process, giving you a way to get back to a 'normal' sex life again. The best chance of full erection recovery is early and active rehab, using the combo of pills, pump, and pricks. If you need any detailed info, I got lots of links for you to read up on it, just ask.
