i would ask your dr about what is his plan during weening you off of the test c. obviously there is going to be increased estrogen. are you already on a ai? since you have been on trt for 1 year, your most likely shut down. how does he plan on bringing you back up? hcg? check to see if your insurance covers hcg if that is his plan. otherwise its big $$$ out of pocket. definately get these questions answered so you can begin to plan a course of action.
i was in a similar but different situation recently and i had to find another dr. mine was getting paranoid due to the fda warnings. i have been on trt for 2 year, so they wanted to ween me down to from 200 per wk to 100 per wk. my suspicion was to eventually get me off of t completely due to the conversations and emails i have been receiving from the office. good luck.
cheers,
