I just got two boxes of the 5 mg tabs of proscar, 30 per box, ready to cut them up. First I want to double check on the libido problems. Can these libido problems be prevented with the use or trib terr 4-5 g a day?And I have also read these problems go away after use of proscar because of short half life, this true? I would like some first hand experiences, but any info is awesome.Thanks
