I have been experimenting with Staxyn for about a month and had mixed results. The first couple of samples the doctor gave me worked pretty good but since then, it has been mixed. I had taken Staxyn on Sunday before going to my GF's house and then we ate a meal, so it was about 90 minutes later that we had intercourse. I got an erection but then shortly after starting, my erection went soft and we couldn't continue. Anyone else have this problem? When I was on Viagra, my Dr. suggested that I take it on an empty stomach, which seemed to help.
