i was on 175 mg test once a week. On trough day a few months ago I was measured and my total t was 901 with an Estradiol sensitive of 24.5. I was then tested a few months later and my total t reading went way down on the same dose to 429 total t and 18.7 on the Estradiol sensitive test! My dr. then upped my dose to 200 mg and I was retested a month later and my total t was 551 with an Estradiol sensitive test score of 31.4. I do not understand what is going on here! The office said sometimes your body can start metabolizing the testosterone faster, is this true? What can explain this? Please note, unfortunately I do not have SHBG or Free t readings.
