I don't recommend it. I recommend dutasteride Instead. Less chance of fucking up your sex drive. Google "post finasteride syndrome".
My urologist put me on Proscar (finasteride) to treat an enlarged prostate when I was in my late 30's. If he would have warned me about the side effects, I would never have filled the prescription. All he said in regards to sides was that my hair might grow back. That never happened.
What did happen was over the next 30 years I suffered at least 4 of the down sides, which I starred below. After he retired, I found a new urologist who took me off that shit and started me on TRT instead. But, after all that time, the damage was done and it was irreversible. What's more, Proscar did not prevent me from getting prostate cancer. If the old urologist was still alive, I'd sue his ass for medical malpractice.
Should your doctor ever recomends you take finassteride, fire him and get a new doctor.
