I took propecia 4 years ago and ever since the libido went from a 10 to a 2 overnight. My endocrinologist says propecia can permanently damage a few percentage of guys even though he says my levels are in normal ranges, and to "maybe it will get better with time". He won't help me out, so I gotta self medicate.
I'd love to take safe, low, long term dosage long term to restore sexual function.
thanks guys,
