My urologist injected me with .2ml of bimix (30 mg papaverine/1 mg phentolamine) in his office this morning.
I told him that folks here suggested that amount as a safe dosage for the trial run. His patients typically use Caverject or trimix, so he has little experience with bimix.
I took 100MG Viagra about 1.5-2 hours before the shot.
I got an erection that is still with me over an hour later, although it never reached usable status. Got about 80% of what a good, firm, very hard erection would be like.
Only downside is he used a 5/8 inch, 25 gauge needle, rather than a 5/16 inch, 31 gauge needle that I will be using. I definitely felt the shot. Hopefully the smaller needle will be less noticeable when I inject myself.
Also considering an autoinjector. If anyone knows of a good, relatively cheap one, let me know.
Very pleased with these initial results.
No word yet on my PSA test from Monday.
