momo, I started late in the game. For me xandrox works slightly better than regular minoxidil. (I have tried to do it over a period of a week or 2 weeks). I shed more when I use his regular minoxidil as opposed to xandrox. I had posted my six month picture update. I seem to have maintained. However, many will probably feel that I can do this maintenance with just the regular big 3.
I am still NW5, I would be happy to get to NW4, if not I won't really care too much.
Recently I have added proxiphen-N twice a day and spin-trap to my regimen. I will update my progress in six months.
