Hello! Action of a preparation proceeds on the average till 4 o'clock, depends on a functional status of a liver. Unfortunately, we have no a reliable data, that the dosage of a preparation influences duration of its or his action. In our opinion the necessary dosage steals up the doctor depending on an expression of erectile dysfunction. Yours faithfully, Vadim Viktorovich.
