just get an Rx from your doctor.

I'm pretty sure TER is not fond of posts promoting illegal transactions.

Do a google for "coinrx", it's a bitcoin only pharmacy out of india (where they actually make this shit).
They have a myriad of non narcotic prescription drugs for pretty good prices, discrete packaging too.

 
You're an adult (ostensibly) so don't fuck around with this stuff, do your homework. I'm not going to tell you not to do it, because you're a grown ass man, but don't come complaining to me when your heart literally explodes.

Also, cialis/levitra are better, so you might as well give them a shot while you're at it. For me, viagra just keeps me hard forever, and gives me a headache, and it takes forever to get off. Cialis is great for shortening refractory period, so you can pop more times in a sesh, and doesn't give me headaches, so that's nice.
