I have used Edex for about 6 months. I couldn't take the aching pain from the alprostadil and so my Urologist switched me to Trimix. But a 40ml/cc Edex dose would have made me hard for over 4 hours and going to the ER. Trimix has never come close to having the same effect.
I have discovered with both types of injections that after I climax, if I am flat on the bed, that the potency goes away. But if I immediately stand up and walk around for a few minutes, it comes roaring back. Something about the blood flow.
You are very lucky to not have to deal with the alprostadil pain.
