When I went to pick up my order, the pharmacy had (after calling my doctor) substituted the Muse 500 alprostadil. So that's what I tried. They told me to keep it refrigerated, and the boxes felt cold, so I have no reason to suspect improper storage.
Back home, Muse alprostadil urethral pellet insertion with the plastic applicator went exactly as described in the Muse leaflet. I wanted to give it real test, so against instructions I lay down on my back and avoided any arousing thoughts.
At 10 minutes, still no erection. Yes, there was a bit of the urethral stinging and a vague deep dull penile pain the instructions mention, but not enough stinging or pain to really matter. I might not have noticed either symptom if I had not been looking for it.
At 15 minutes, with a total lack of effect I stood up and within a minute I had a half-mast erection. This lasted as long as I didn't lie on my back. Doing so caused immediate softening of the erection. Curiously, other body positions brought the half-mast erection (and dull pain) right back again.
This state lasted about 70 minutes, then the effect began to wear off, though some residual effect remained for another hour.
