Wasn't Royaume or That Guy the specialist?
FDG9, minoxidil and several things. You have to go through the thread buddy, don't know them one by one. Noisette posted some of the patents too.
I ain't no specialist,
but it's kinda hard to keep it all straight since they apparently tested a number of compounds through the years. I think it wound up settling on minoxidil and some FGF9 thing that Noisette had shared.
But not necessarily confirmed, since this is all info gleaned from various patents. It does appear that there will be at least 2 different compounds, though.
