I don't get it. You are not on TRT right now? But have been taking AI?
Even if you were on TRT in the past, you should still be on it. Your symptoms might be caused by other things, but you didn't provide the numbers. Also on your E2 what is the actual number from the recent test? And what is the scale of "normal".
I was doing arimidex monoteraphy to boost my testosterone levels which looking back now was really stupid idea but it has been done and it's even used in pubertal boys to delay the fusion of growth plates. Right now off everything, my testosterone is normal. Latest numbers from October:
Testosterone: 23 nmol/l (10-38)
SHBG: 36 nmol/l (14-71)
Free, calculated testosterone: 358 pmol/l (230-575)
Estradiol, sensitive: 25 pg/ml (<40)
Estrone, E1: 44.8 pg/ml (<80)
So on paper, it looks normal to me. Only thing that has been weird is my DHT level in blood.
DHT: 1.00 nmol/l (1.03-2.92) So according to blood, my DHT is low. Doctor however couldn't give me any type of answer on the DHT.
I even tested blood markers for adrenaline secreting tumor because of the constant sweating/hot flashes which came out normal.
