a couple points to add:
1. you can get bloodwork done and results the next day.. see my signature on how to do it without dealing with the beaucrasy of going to a doctor and waiting for results
2. you always want to use an AI from day 1, you learned your lesson already but just need to clarify for others
3. once your estrogen is out of control the best way to get it under control is stopping the steroids and adding an AI at a proper dosage. you wouldn't try and stop a semi with spikes on a track vs. just hitting the brakes right?
