Cialis (Tadalafil) Specs
Cialis is a licensed ED treatment that stays active in your system for up to 36 hours. During this window, you’ll get multiple “uses” (erections) out of one Cialis pill. It’s the longest working ED treatment available on the US market.
How does Cialis work? The active ingredient in Cialis is tadalafil, which helps blood vessels in the penis dilate, increasing blood flow. Tadalafil has been clinically proven to help over 81% of men with ED achieve easier, more reliable and longer-lasting erections.
