need help with dosing

hey, i’m a non binary person that wants to appear more androgynous and masc, i would like to go on t, but basically there are some effects that i would rather avoid or not have them appear as strong as on t alone. I heard stuff about a method that’s basically taking t and a t blocker (from what i’ve heard mainly finasteride) at the same time. My minds pretty much settled on trying that, I just have no idea how should i dose it, which is what i need help with.

thank you<3
