Taking Propecia at Night vs Taking Propecia in Morning

Hi Dr. Rassman, I have read in some of your earlier blog entries where you said that it is best to take Propecia in the morning because testosterone levels rise while you are asleep. But I was thinking that it would be better to take the medicine for you go to bed, because then while your testosterone levels rise during the night, propecia would be in your system to stop it from turning into DHT. What do you think?

Morning is better. If you take it by 7am when your testosterone is highest, only 25% of the drug will be left in your blood stream, as the half life is 4 hours.
