When I went to have my first injection at my urologist's office his PA gave me Caverjet as he said about half the men can use it and they prefer it over Bimix and Trimix because they have had less complications with it such as Peyronies. I could not take it because of the aching. The other good thing about Caverjet is it is covered by most prescription coverages of insurance benefits whereas the compounded medication generally are not. The negative is if it is not covered by your insurance it can be considerably more expensive then the compounded medications. I am pleased it works for you and from what I have been told it is the best injection medication if you can take it.
