The effects of Cenforce 100 can last for up to 4 to 6 hours, providing a sufficient window of opportunity for sexual activity after taking the medication. Cenforce 100 typically starts working within 30 to 60 minutes after ingestion, although the onset may vary among individuals. It is important to note that sexual stimulation is necessary for the medication to be effective, as sildenafil does not cause spontaneous erections. https://www.genericday.com/cenforce-100-mg.html
