This is my 1st post, so bear with me. I started TRT about 6 weeks ago at 200mg once per week of test cyp. For my 1st follow up lab, my doc instructed me to have the test done the day prior to my injections, however I inject on Sunday, and did not get to the lab until the following Tues morning. The dr was aware of this and had no issues. When I received the results I was a bit surprised. Total test 541 (348-1197) and free test 15.1 (8.7-25.1). These numbers are much lower than I expected on 200mg/ week. I'm still learning about half life and wondering if my results are to be expected having tested at day 9? I know that labs are really the only way to know for sure, but is there a way to estimate what my peak levels were based on the half life?
