Typically from my experience, hematocrit ranges can be followed/trusted for that marker, so I would donate if it gets marked high. The chance of it getting higher with a lower T dose is low and hematocrit should reduce as your blood serum testosterone reduces.
You may want to reduce AI dose slightly more than your plan. Your e2 is going to go down with a lower T dose, so instead of 8-9 drops, you may want to try 6, lest you lower your e2 further.
Also, isn't your TT and FT above range at 40 mg eod? 30 mg eod may be a good place to start, but I may try 25 mg eod.
Double red blood cell donation should not change your other markers.
4 weeks should be enough time to stabilize after changes and get follow up blood work done.
Inflammation typically manifests itself with high cholesterol levels. Our arteries and blood vessels literally get inflamed and our bodies increase cholesterol blood serum levels to help mend the inflamed vessels, which causes plaque build up and cardiovascular disease.
Inflammation can cause thyroid and liver issues, as shown by your high Tsh and alt/aslt. For most, inflammation starts in the gut as leaky gut to varying degrees. It can also cause insulin resistance and diabetes in some people.
You may want to get additional thyroid labs. Tsh, ft4, ft3 and rt3.
Hope this helps.
