I'm a cialis lover but unfortunately it is losing its power and my best middle leg friend isn't reacting to cialis any more, so I guess viagra is gonna be my other option. I read from the ukmedix news that a medical company is trying out something called “nano viagra” which is supposed to work in less then 10 mins after directly application on the penis. While this new medicine comes out to the market, I guess many of us are going to stick to viagra for a little while
