Rogaine/Minoxidil is Nitric Oxide - if you use external nitric oxide your own production goes down. It is not just the anti-5AR effect.

If you quit then you lose even more hair since your own nitric oxide production is now lower.

Helen the guy on Hackstasis explained this and it makes sense.

If you are in PFS you need to avoid all that. Because in PFS you are already not in an optimal body chemistry. Even when you get out of it. I would at least give it 1 year stability to even think about trying that type of stuff. You are playing w/ fire in my opinion if you start this stuff too soon.

I won't touch any of that stuff with a 10 feet pole even after I get better. Rather be bald.
