Should I lower my dose based on these levels?

3 months in with 5 mg ev injections weekly and spiro 50mg daily I had my first labs done. I had estradiol at 298 pg/ml and testosterone at 22 ng/dl. These were my results at trough.

At 6 nonths I got labs but my doctor would not test at trough, I tried to push for it but they told me to come in at day 4 after injections for a peak test. Those levels were estradiol 531 pg/ml and testosterone 21 ng/dl. I am planning to do further trough test on my own.

Now my doctor wants to cut my dosage in half which feels concerning. Going from 5mg to 2.5 mg weekly. Would going to 4mg ideal or are these levels appropriate?
