Hi, I am new here from odessa Texas. I have been on trt for about three years. Been on pellets and injections. My level has been as hi as 2300 ng/dl on pellets my hemoglobin was over 18 and I was tired and sleepy all the time with headaches estradiol was high also. Is this from hemoglobin or should I check something else. I noticed I was was waking up at night with high pulse rate when levels were high.
