Just to show how silly complaints of side affects can be here is my experience with generic Fin:

I first tried it a year ago and after a few weeks felt I got headaches and that it was destrpying my hairline..thats some of the sides I read about so i panicked and quit after a couple months...

fast forward almost a year later and my hairline was still receding so i decided fin wasnt teh issue. i got back on and ever weary of side effects I paid close attention...this time no headaches but an increased sex drive with stronger than normal erections..what a joke..if there was ANY real side effects they would have repeated themeselves...no headaches nothing negative..

I take generic fin from Publix/kmart..something like $5 a month... I cut the proscar into halves and take mon, wed, friday.

So basically my experience is no true sides..doesnt seem to help the hairline, seems to help the crown a bit..Ill try it for 6 mponths and see...
