All these is possible due to the properties of the active substance, Sildenafil.

As claimed by scientific and clinical studies, Viagra is the best means to treat erectile dysfunction. Initially, Sildenafil was intended to help people with heart and blood pressure diseases. But, during the first clinical studies male participants have noticed that the drug causes hard and long lasting erection. Legends say some were even trying to steal the pills. Since then, for more than twenty years, diamond-shaped blue Viagra tablets are the most widely used medicine for the treatment of impotence in men. Also, millions of healthy men take Viagra as a recreational drug for more exciting sex.

According to medical studies, more than 80% of patients note extraordinary improvement in erection quality and duration within twelve weeks of treatment with Viagra tablets. What is great, placebo has almost no effect at all. That means Sildenafil is one of the few drugs which really work. After all, everybody knows, what is Viagra due to books and movies.

Difficulty achieving or retaining an erection might be caused by various reasons. Most commonly, nowadays men suffer from erectile dysfunction because of  stress, unhealthy diet, poor ecology, etc. No matter what is the origin of impotence, Viagra will easily cure it.

All you have to do is buy Viagra, and take a pill at a dosage you prefer about 20-30 minutes before sex. Swallow the tablet whole, with plenty of water, better on an empty stomach. After any kind of natural sexual stimulation, for example petting, you will get a firm boner which could last up to four hours or even more. Erection disappears as soon as you come. The most effective Viagra dosage is 100 mg, but some prefer taking smaller amounts of Sildenafil.
