I have had a similar experience the the OP. While I have only been on hrt since the beginning of November, my testosterone levels have not dropped at all despite the fact that my estrogen levels have doubled. According to my doctor, Spiro can sometimes take 6-8 months to make a significant impact on T levels. I won't see her again till mid June, and am really hoping they have dropped by then. Only time will tell, but it definitely has me a bit concerned because my musculature is one of the few dead give aways I have that is preventing me from passing most of the time.
