I had a HT consult. The subject of proscar came up. My Dr, opened a big fat text book, which records drugs like Propecia, similar drug to proscar, and it says something like the results were no demonstrated for men aged 41. My Dr told me that if you take proscar when you are 41, it will be useless. According to my Dr, these results were recorded by the company producing proscar. Is that true? I used to have proscar (1/4 tablet per day) for 5 years, then I had a problem (could not maintain my erection), when I stopped it I no longer had this problem. I stopped it for 11 months, and now I lost a lot of hair. Got back to it now, but, in accordance with this Dr, it will not work. Could you please share your thoughts on this
