Driven, I've been researching low dose T. There isn't anything at all written on any medical page. (You can find stuff on low dose T, but only for post menopausal women for libido.)
There's stuff on tumblr and youtube. Some people end up staying on low dose, some people increase the dose, and some people go off. There are some permanent changes. I am going more and more towards wanting to take T, but I have decided to be in gender therapy for 6 months to a year. Gender therapy is a good experience for me and I have a very good counselor who is a transman. GT doesn't seem to be making me "less trans" in the slightest.
