Started TRT, Initial Libido Burst Followed by Considerable Drop

You will not hear such guidance here. Sounds like bro-science.

Target is E2=22pg/ml. New AI dose is old AI dose x 16.2/22

Your thyroid is/was a mess.
TSH should be nearer to 1.0.
TSH can be low if you have not been using iodized salt.
TRT can make/restore metabolic rates/damands higher than thyroid function can support.
Check oral body temperatures to eval overall thyroid function.
Outer eyebrows sparse?

Try injecting T twice a week and taking Arimidex/anastrozole at that time. Go to T cyp only and T levels will be steady. Do labs always halfway between injections. Your T and E2 levels are not steady with weekly injections and AI dose needs to match T levels that should not be changing.

Your labs need to include FT.

Please always post labs in list format with ranges, not buried in prose.

As well as thyroid being a possible weak link, low cortisol can be too. Test AM cortisol and do at 8AM.

The symptoms of low thyroid function are very similar to low-T.
