Finasteride
Finasteride* (Propecia, Proscar). One approach is tablets in the morning and tablets in the evening of finasteride. The finasteride tablets are branded as Propecia, but generics are available. The other method is taking the brand name drug, Proscar which contains finasteride. The tablet is not scored, and it is hard and oddly shaped.
*Without finasteride, results are only minimally improved over an estrogen only program.
