Does everyone get side effects?

[epac]

Or just a high percentage (less strong erections, low sex drive, watery sperm) I'm 22 and I have just started hair loss and this is my main concern before I jump into this

right around 1%...dont believe all the sh*t you hear on forums...the clinical trials showed that 1% of people got side effects. The placebo was right around the same percentage, slightly lower.

Ive been on propecia around 8 months and i got one side effect: Thicker hair.
