So I used RexMD, it does require a prescription but it's pretty easy to get they ask some basic health questions and if you have to log your blood pressure (can check it in pharmacy), seems pretty much like a rubber stop, doubt it will show up on your medical records if you end up in the hospital...20 mg sildenafil / 90 days supply was $120 but with discount and tax, shipping came out to $90 so approximately $1/pill...Sometimes It has diminishing effects on me so sometimes I use 2.... in terms of not letting the SO now, I had it shipped to a local UPS store (mail service ) under my name, and picked it up from there...
