Where should estrogen levels be for a 47 year old male? For my own interest I had a test done this week and the results were 38 pg/ml. My Dr tells me that it should be 10-60, so my levels are normal. I could swear, however that I saw a post by Matrix stating 7-17 was optimal. I am currently taking 200mg test cyp every 2 weeks, but I am going to split it into 100mg every week to see if that makes a difference. My last free testosterone result was 8.9 mg/dl, and the Dr tells me the range should be 9.0-30. I have 2 concerns. #1 is that my free testosterone levels aren’t “in range” and if I’m introducing an outside source, where it's going if it’s not raising my levels. Is it (excessively) converting to estrogen? Concern #2 is that I have a slight case of gyno and (maybe it’s all in my head) I swear I can tell a difference at times between the every other week shots in tenderness and size of the lump. But, if my estrogen levels aren’t of concern, maybe I just need to quit worrying. Opinions, given my limited information?
