EDIT: it does have a warning for male use only so in the mtf area it might be a bad Idea. Do the research, ask your doc, and I hope you get a badass head of hair.
Nah, if anything Finasteride is better for transfems than for cis men: A lot of the potential negative side-effects become potential pleasant surprises for us; some of the concerns regarding depression remain, but generally speaking it’s a relatively safe bet for people who don’t want to take T-blockers (yet).
That said: Proper T-blockers are the much more comprehensive solution and usually make Finasteride superfluous, so the primary argument against it in our case is honestly, that it tends to be a better choice to go all the way from the beginning. Even for people who can’t get a prescription, DIY (→ /c/diyhrt) is usually still the better decision.
Ich denke, dass ist an der Stelle das Zitat des Tages und eine in der Tat exzellente Zusammenfassung des Problems!
