Hey Younggun,
ive been taking Propecia for over 8 months and i have not experienced any "sides", I will say that im not as horny as i use to be, but i still have my morning erection. I got scared for a while because i started reading all those post and then i started having "sides". But i stopped taking it for a week to see what happen and all of a sudden my libido jumped into hyperdrive! basically the drug pretty much effects you while your using it, once your done with it, youll be back to normal. Either way i know Propecia is a temporary fix untill i order my first hairpiece. Dont stress to much about it man or else those side effects will take over your life. best of luck to yah in your journey! make sure to post pics
