Let's not forget that Finasteride has horrific side effects for men and can induce permanent / major sexual dysfunctions and drops in libido.

I gave finasteride (and dutasteride) a try in my 20s. It didn't work, but I'm lucky that I didn't end up suffering any of those side effects you mention. I was definitely reckless in taking it without really considering the negative possibilities.
