Thanks for the feedback! Really appreciate it

Diet is on point now, consistent 1kg per week down,
how much t3 could I add to help speed along the BF?
Which type of Test would be best in this case? and with lean gain would I run it for 12 weeks? would anything else be added to it?

I did thyroid bloods recently:
fasted; result (normal range)
T4: 18.41 (10.80-22)
T3: 5 (3.10-6.8)
TSH: 1.79 (.27-4.2)
