The principle of action and composition of the drug

Undoubtedly, Viagra is considered the number one agent for the treatment of erectile dysfunction and the return of potency.

This drug treats the main cause of impotence, namely the inability to have a sufficient erection for the conduct and completion of sexual intercourse.

The drug helps many men who have intimate dysfunction, to eventually achieve a normal erection and keep it for a long time, but only if there is enough sexual arousal.

Viagra from Canada provides real opportunities for many men suffering from dysfunction in the field of erection, to receive a penis reaction to sexual arousal. In combination with a strong sexual arousal of a man, this drug will begin to improve the blood supply to the penis, filling it with blood to such an extent for the appearance of sufficient erection.
