Honestly these off brand dick pills are just over saturated multi vitamins with trace amounts of the active ingredient in viagras. I wish I could get the real thing, but can't really ask my regular Jew physician because he's my parents general doctor too. So I'm relegated to this 7/11 garbage, but they still kind of get the job done. It's actually very easy to build a tolerance to this stuff so I take long breaks in between. And if you have to ask why anyone would ever want to take a dick pill, you never have.
