Tazalis

Tazalis is an extra-strength orally administered drug used to treat male erectile dysfunction (impotence).
Containing the same active ingredient as regular Cialis (Tadanafil), Tazalis works faster, and its effects last longer.
Tazalis may be taken when needed: it works fast and lasts long - one dose can work for up to 36 hours, allowing you to choose when you want to have sex over the next 36 hours.
Following sexual stimulation, Tazalis works by helping the blood vessels in your penis to relax, allowing the flow of blood into your penis. The result of this is improved erectile function.
