I'm using Dutasteride, and it works amazingly well when you don't forget to take it.
I'm running low on my supply so this is about the time I come back on here for a quick look-around.
I'm about a N2 at the moment, but when I have the cash to use it every day I can pretty much get to an N1, although bear in mind i've been on Minoxidil every day for.. 5 years (Holy crap, 22 now, started at 17), have also been using Nizoral twice a week or more and recently started using Nizoral cream on my hairline to speed up regrowth there (seems to be helping).
