Men with erectile dysfunction might use a medicine called Cenforce 100 Professional to address their condition. Use Cenforce 100 before engaging in erection activity. Although you can take Cenforce 100 up to 30 minutes or 4 hours early, you should take it approximately an hour before having it. Typically, it's not a good idea to use Cenforce 100 more than once per 24 hours. Cenforce 100 may be taken without food. It functions via dilation and contraction of the blood arteries in your lungs, which facilitates blood flow.
