Advantages of Viagra Over Other Erectile Dysfunction drugs (Sex Pills)
This pill has been used by millions of men over the course of over 22 years, establishing itself as the leading drug for effective treatment of impotence.

The effects of Viagra can last for up to four hours compared to most Non-tablet ED treatments such as MUSE, Caverject and Vitaros that tend to remain active for shorter periods of time (anywhere between 30 minutes and two hours). This shorter timescale most at times is viewed as an inconvenience for some men.
It is important to note that this does not mean that an erection is sustained by the individual for four consecutive hours. Instead it simply means that one can be achieved during that time frame if sexual stimulation is given.
The majority of men that use Viagra are able to achieve an erection within 30-60 minutes of taking the tablet, when sexually stimulated.
