But I must warn you if you don't get a
test and take this you can go to low and it is worse then to high. But if your
test comes back on the high side or over the top of the range then try taking one pill a day until you get real hard wood all night long keep taking it. But if the wood stops stop taking the pill until the wood comes back then go back on it but do half. Keep doing this until you find the right level and dose the window is small.
