Talk to your doc. about TRI MIX, it is a compounded injection, like Caverject, in fact Aprostadil is one of the three ingredients.
The cost is waaay less than Caverject. 5ml. costs me $85.00. I use a 20 unit injection, which comes out to 5 injections per ml. x 5 ml= 25 injections @$3.40 per injection.
Actually I recently found out that some docs start you on it early, after surgery.
I missed out on that, three and a half years ago.
This is an example goodrx.com/caverject.

Do some research on it. You can even get an auto injector to put the syringe in, to not have to watch the needle go into prized possession.
If your doc. doesn't know about it, see someone else.
This is new to me also, but it is much better than everything else I have tried.
Good luck with your future recovery
