I started TRT with 200 mg test cyp every two weeks about six months ago, but experimented with shortening the interval to about 10 days and generally felt better. However, in my last round of lab tests my testosterone level came back at 13.84 mg/l (ref 2.80 - 11.00) and hemoglobin at 18.7 g/dl (ref 13.5-17.5), hematocrit 54%. I discussed this with my doctor and we decided that a socially useful way to bring this down would be to donate blood. However, this morning at the blood bank the reading was 20.2 and they refused to accept me as a donor. What to do? One solution seems to be to pause TRT until the hemoglobin level is acceptable and then resume TRT at the two week interval despite my feeling perhaps worse overall as a result. I'm wondering if anyone else had this problem and what they did to solve it. Thanks for any advice!
