Hi There Life,
I am pleased to see you learning as much as you can and taking control. Here is my experience and the information that you requested.
I had a lot of aching with the Caverjet and could not used it. If you are not having any significant discomfort with Caverjet then it is good to use as it has a lower level of incidences of Peyronies and priapism.
I am using Bimix. My cost including two packages of 10 syringes each is about $59. I have been using Bimix since April and at first went up to a dosage level of .35 cc's. At this level my cost was about $3.00 an injection. I started combining the Bimix with Viagra at the end of June as directed by my urologist. Since then I have been able to reduce the dosage down to .15 cc's. Since the combination of the injection and Viagra I have been able to get about a 50% erection unassisted. I may be reading something into the response but it appears that the combination has helped with the nerve rehab or enough time has passed that it is coming back on it's own. It has been about nine months since my surgery and this is when many men report the beginning of natural erections coming back.
I only had the initial injection of Caverjet in the surgeon's office. Once I got the Bimix I began injecting myself. I have probably injected myself 20 to 30 times and have only had two misses. One was when I injected myself too close to the base of the penis and apparently missed the spongy tissue. It caused a spectacular bruise but no pain. The second was just recently when I think that I was too low and again missed the tissue. That was when I was doing it left handed(being right handed). I have found that slowly inserting the needle is better then sort of stabbing it. There is no bleeding when I do it that way and no bruising.
