quitting propecia(fin)

[Receedo]

Hey I'm 18 years old and I'm currently a norwood 2-2.5. I can't really tell if it's getting worse but my hairline's looked the same for 2 years now I also have limited family history of baldness with the worst case being my uncle who's a nw3. I'm now interested in taking propecia to maintain what I've got although I don't know if my hairloss will get much worse but I don't really want to find out hahah. See if I take propecia and maintain what I've got until I'm in my 30s and for some reason decide to quit. Will I go to the pattern if hairloss that I would of been if I never taken the drug or will I just go back to the stage I was before I started treatment? Thanks for reading
