Made in Switzerland, Viasil utilizes quality ingredients to optimize sexual function. By stimulating nitric oxide production, it expands blood vessels to drive blood flow to the penis. This enables bigger, longer-lasting erections. It also provides an energy boost for increased virility and stamina.
Signs of arousal include penile swelling due to excess blood flow into the penile tissues. Viasil contains vasodilators that help the body make more nitric oxide, which widens blood vessels. This rush of blood enlarges the penis for peak sexual performance.
