It took more than a week to deliver the package, but the location of the package was trackable all the time. Instead of Levitra, the package contained Vilitra 20mg, which has the same active ingredient - Vardenafil. It became my favorite and I prefer it over Sildenafil and Tadalafil. First of all, even half a pill - 10mg is more than enough for me! It kick's in within 45 minutes and works perfectly for at least 12 hours. I'm 53 and feel like 20 in bed all this time... ;) It's amazing! In my case, the side effects are slight facial flushing and nasal congestion, which pass within a couple of hours after taking the tablet.
