The first appointment (my only appointment so far) was a basic physical assessment and medical history, including family history. My endo gave me some information on T to look over--nothing I didn't already know from my own research. After that, she asked if I was ready to get my shot today and set me up with one of the nurses. Because I regularly give injections, I was just supervised on technique and self-injected my first shot at the clinic. She sent me to get blood work done right after that.
ETA: I forgot to mention, the way my schedule is set up I have blood work done at 3 months and then again at 6 months. I only go in face-to-face for the 6 month appointment though. The dose I'm on now is low and should be increased pending the results in March.
