Comprar Viagra Original

Viagra is the best-known medication for ED. It is a prescription medication that helps men achieve and maintain an erection strong enough for sex. This occurs when the nervous system releases nitric oxide into the tissue of the penis. The nitric oxide helps in the production of cyclic guanosine monophosphate which dilates the arteries in the penis. The arteries and tissue fill with blood and an erection occurs. Colloquially called ‘the blue pill’, Viagra has been the go-to medication for erectile dysfunction for a little over 20 years. It’s an effective medication but you may need a prescription to get it - depending on where you are in the world.
