you need to take it twice a day
Even the Gisleskog
et al studies (from which I obtained all those dutasteride/finasteride charts and graphs that I've posted over the years) included a couple of graphs showing the effects of taking dutasteride ONCE A WEEK and even ONCE A MONTH (!!) at various doses. They fully support what we've been saying for years, which is that the long half-life of dutasteride allows for very
flexible dosing schemes. You can take a properly-chosen dose once every few days, if you wish, although I personally wouldn't go any less often than once-a-week at the very least. Once-a-month would be pushing it waaay too much.
