    TRT has been underwhelming for 4+ years - Low SHBG

    But to answer your question a lot of the time I go by "feel" and do adjust "on the fly," which unfortunately is a recipe for disaster.

    TRT has been underwhelming for 4+ years - Low SHBG

    60/250/.25 (2x/wk) at the same time had my T at 550 and e2 at 17 right before scheduled injection. All other numbers looked good. Tsh borderline high, I have added seaweed into my diet. However, e2 spike from HCG is unaccounted for. And Anastrozole doesn't block e2 effects from HCG anyways...

    TRT has been underwhelming for 4+ years - Low SHBG

    Vince Carter, I'd love to hear your current protocol. E2 should be quite similar to shbg for optimal sexual functioning. So if your SHBG is 14, then you will have to lower your e2 to around 14. You will become a stud in the bedroom, however you might experience some low e2 symptoms. Also...
