Better with high free T or total T or both?

I've heard this also. But I like to play it safe and keep things withing range, or as close as possible

another thing you could check up on is your sleep. Sleep apnea can also drive erythrocytosis. It may well be just you reaction to the T, but if there is doubt on your end, it would be good to know if you have apnea. In my case, clearly it drove the erythrocytosis with the T. Since getting my apnea under control, losing weight etc. my Hematocrit and Hemoglobin have both stabilized at high normal levels, at worst Hematocrit at 51%. But it took months, with cpap to see it stabilize. Now, I donate blood about every 4 months or so, but wouldn't need to.
