1. My insurance covers 8 pills for ED inflicted by a surgery or injury that was done and covered under my policy. For ED of any other form, no coverage at all. This is 8 pills, regardless of type or dose. So I get 8 20mg Cialis and cut them up to get a daily dose of about
5mg.
Other guys here report 5 pills and some, no coverage at all. Trimix is really iffy. My insurance denied it multiple times as not medically required, but with some assistance from a pharmacy, it was finally covered as 10ml per month.
2. Wow. 40% at 4 months out is GREAT.
3. Dr. Mulhall (google his "Saving Your Sex Life" - John P. Mulhall, MSKCC) has a chart that implies injections could start as early as 6 weeks after surgery if pills don't work (explain to me how anyone 6 weeks out could have tried all the pills often enough to give up on them?), but my uro says not before 3 months.
I would try all the pill variations first. Ask your uro or GP for samples of all of them. The logistics of a pill are so much easier than injections.
That said, your uro should expect you to have a "training" session, where you inject with the real stuff, and see how you react. Mulhall requires 2 sessions. That will require that you get the prescription, find a compounding pharmacy, get the coverage questions sorted out, and get it made/ shipped. That took me 5 weeks, so if you have a "deadline", talk to your uro now and get the ball rolling. If you wind up with Trimix you don't need, it will keep in the freezer for up to 6 months.
RT likely won't do anything to erectile function at the beginning, so don't look at day 1 as the end.
