TSH: 2.96 - too high, should be nearer to 1.0, reference ranges are useless
fT4: 1.1 - should be mid-range or a bit higher
fT3: 4.0 - midrange = ~3.2, can be elevated by rT3 - adrenal fatigue
DHEA: Need range and should be testing DHEA-S, not DHEA as it moves too much
Low cortisol and low DHEA-S suggest an adrenal problem. Low body temps when fT3 should be supporting good body temps really does suggest elevated rT3 blocking fT3 as part of adrenal fatigue. Read the thyroid basics sticky noting these terms and consider purchase of Wilson's book on adrenal fatigue to see if he seems to be describing you.
Cortisol: In the adrenals, progesterone-->cortisol, you could try some progesterone cream applied to inner forearms. Get Rx or KAL brand [2%] via amazon. Or Rx cortisol drug.
PSA and prostate: E2 is the risk factor, not T or DHT. You need to manage E2
E2=36 WAS way too high. target is 22pg/ml. Were on anastrozole at the time? Appears not.
Anastrozole is a competitive drug, to T, and must match T levels. You need to inject twice a week to get steady T levels and take anastrozole at that time. For low dose management, use a liquid 1mg/ml solution, making your own if needed using vodka. You cannot do this splitting pills.
