I was on it for about 25 years or so. It was prescribed for me to treat an over-active prostate. I could have drowned someone. Would even have seminal fluid leak out while taking a pee. It fixed all of that. I remained horny, but no where really to go with it. Self service was a regular thing. (I am married!!) In my late 50's, I discovered the AMP world. All was fairly good for a few years, but then junior decided to call it quits. I'm in otherwise good shape. 6ft , 180, good blood pressure, low sugar, cholesterol and all of those things. Started trying V and C. Got some help, but not a lot. Then I read about how finasteride could affect sex drive and equipment. Stopped taking it about a year ago. Volume is about normal, but didn't notice a big difference in junior, but he's a bit more responsive. I would not recommend it for something like hair loss.
