One of the most significant things to remember about Cenforce 100 is that it takes 30 minutes to reach its peak and can last up to five hours during sexual stimulation. It may not act as rapidly as Viagra if you take it on an empty stomach. It is recommended that you take it at least one hour prior to sexual activity. It's vital to note, though, that Cenforce 100 only works when sexual excitement is present. If you take it more than once a day, you can have some unpleasant side effects.
