Finasteride at 1mg and 5mg Dosages

Is propecia at 1mg as effective as finasteride at 5mg ? thankyou

What was published in the original work on Propecia was that the 1mg dose was just as effective as the 5gm dose for treating hair loss. One might suspect that there is a dose response relationship and that a higher does might have more of a benefit than the 1mg dose, but that is strictly guess work. I only know for sure what I read about the subject and that data is well documented in the literature and through the FDA approved trials.
