I went to my Informed consent doctor for an initial appointment. She asked all the standard questions a GP would ask at a first appointment. Medical history, allergies, mental health, STD's etc. Then she asked more specific questions like sexual orientation, if I had a partner and how they felt about my doing HRT, relationship with parents, how I identify gender wise etc.
It wasn't in an interrogating way though, she was literally just filling out a sheet of notes. She then went on to ask what kinds of effects I was hoping for and what I was worried about.
At the end of the appointment she scheduled me for an "informed consent" appointment in which she would actually read me the long document and risks and then teach me how to inject.
Super easy. From first phone call to first injection, it took about 2 weeks and some change. However, I didn't start feeling significant effects until I was 2 weeks on T.
