How does Viagra Connect work?

Viagra Connect works thanks to its active ingredient, Sildenafil Citrate. This is a medicinal agent known as a PDE5 inhibitor, which encourages blood flow within the penis. It does this by targeting the enzyme, phosphodiesterase 5, that is responsible for smooth muscle contraction in the blood vessels supplying your penis. By improving blood flow in the area where you need it, the better the chances of an erection.
