The PDE5 inhibitors sildenafil (ViagraR), vardenafil (LevitraR) and tadalafil (CialisR) are drugs which are taken orally. They work by blocking the action of PDE5, which causes cGMP to degrade. cGMP causes the smooth muscle of the arteries in the penis to relax, allowing the corpus cavernosum to fill with blood. That in turn causes erection.

Testimonials

I received the package about March 15th. The package was sent - not due to an error by you - to another city by an error at the post office, and to cover their tracks, they left a bogus slip saying that the package was not left as I wasn't home, which is untrue, and to pick up at the post office in 2 days. The pills work without going blind or experiencing the Blue swirl syndrome...but a slight headache is all that I noticed. GJ
