My experience was the same. I went in for my first visit, the doctor asked me about my goals, whether I was living full-time, she looked at my blood work from a recent physical and gave me the prescription for Estradiol and asked if I wanted Spiro as well. She sent both prescriptions over to my pharmacy, had me make a follow-up appointment for 2 months out and I was done in 20 minutes.
Now I will say, I'm in very good health, I'm physically active, I have a good body weight and am still fairly young. If you have potential complicating factors, your doctor may be more cautious.
