Forzest 20 mg is a medication that contains Tadalafil, a type of PDE5 inhibitor, and is used to treat erectile dysfunction (ED) in men. It works by relaxing the blood vessels in the penis, allowing for increased blood flow when a man is sexually aroused, helping to achieve and maintain an erection. Tadalafil, the active ingredient, increases blood flow to the penis by inhibiting the enzyme PDE5, which normally restricts blood flow. https://www.genericday.com/forzest-20-mg.html
