I have ED severe enough, post prostate cancer, that I use Cialis daily 10 mg, have tried P shots, (helped in some ways improved sensitivity and added blood flow for larger girth) and am now getting Bocox (botox injections) every 3-4 months (a game changer). In addition, I use Tri Mix as well. If you think you have it bad.....I am going to tell you, strap on your big boy pants and be a man. First, the Tri Mix needle is a pinch at worst. Not bad at all. IF it works for you, it will produce a good erection. IF it works for you, it could produce an erection that will have your girlfriends going, "again???". And I have not even touched PT 141, (the nausea usually clears after the first dose or two) (get the real stuff not a non prescription cheap knock off) which is a sub q injection into your belly every couple of days, that in many, produces erections total on their own, sometimes off and on for days! If you can't do this....you don't really want sex that badly. Sorry to be blunt, but you have not even begun to try.
