Answer:
Finasteride is a very dangerous drug which many men have turned to prevent hair loss. As one who took the drug for only 2 weeks in August of 2010, I can tell you that the side effects are not worth it. It will absolutely kill your libido and cause erectile dysfunction. Plus, other side effects include depression, swelling of the face, stomach & legs (overall weight gain) and "brain fog."
For the past 6 months, I have researched ways to revive my once incredible libido. Even after 1/2 a year since being off the Fin, everyday's still a struggle to feel like I did before taking the drug.
Finasteride/Propecias is not a drug. It's POISON.
