You are one of those really lucky guys that don't react to Alprostadil. Caverject and Edex both gave me super erections but I couldn't stand the aching pain that showed up after about an hour. I tried all sorts of OTC pain medication but nothing worked.
I got the same result with MUSE. Lots of pain but not much to show for it. Lately, I have discovered that I had to switch to the 1/2 inch super fine needle because the 5/16 inch needle was missing something. Trimix works great now with no pain.
Btw, the Caverject, Edex or Trimix injections always seem to last 3 hours plus for me. No matter how much I reduce the dosage, it's still 3 hours.
