Too many men and women, Viagra is known as a male enhancement medication. But what does this “enhancement” mean? Frequently men use 비아그라 구매 and its analogs as stimulators for a better sexual performance-enhancing libido and increasing stamina. And they get disappointed because these drugs are not stimulators. They should be administered for one particular purpose – to improve the quality of erection in men having erectile disorders of various etiology. At the same time, Viagra as well as any sildenafil-based meds, do not enhance low sex drive (they are not aphrodisiacs) and do not improve men’s stamina or change sensations. To understand whether you need to buy 비아그라 online, one should know its mechanisms of action.

Viagra’s Principle of Action

The core function of sildenafil is inhibiting specific enzymes, which are produced in the blood when the normal process of sexual arousal is disturbed for some reason. These enzymes are called PDE-5, and what they do is prevent blood vessels from a natural vasorelaxation after the man gets aroused sexually. That is why sildenafil and similar agents are called PDE-5 inhibitors. They restore the normal process of male arousal and reaching erection resulting from blood supply to the penis.

What is Viagra

As you see, 비아그라 구입 works at physiological, even biochemical level. The only thing it does is modifying the biochemical composition of blood, stimulating widening of blood vessels. It can not influence libido or sexual desire as well as improve men’s physical characteristics, such as stamina.
