Tadalista 20 mg is commonly used as an as-needed treatment for ED. It does not increase sexual desire and does not cause an erection without sexual arousal. The medication works only when a person is sexually stimulated. A key feature of tadalafil is its long duration of action, which may last up to 36 hours in many people. This provides a longer window of opportunity compared with some other ED medications, although individual results can vary depending on health, lifestyle, and other factors. https://www.genericday.com/tadalista-20-mg.html
