Does Fin always cause low Libido?

Does Finasteride always cause the user to have a low libido?
Or is this a rare side effect for the 3% who get sides?

Does it last as long as you take it? Or just the first few weeks?

No it doesnt always cause lower libido. This is one of the known side effects than can occur. However some say it even increases their sex drive.

The % of guys that experience side effects is not accurately known. Its safe to say i think its more than 3%.

There are millions of guys on the drug with no issues as we only hear about the negatives not the positives. Guys with positive things to say generally dont hang around on hair loss forums.
