    The usual run around

    I have 30 years as a Firefighter Paramedic, so I am educated in medicine, even more so than most, but the hormones trips me up mainly due to my memory. 20 years ago I was caught in an explosion containing Dioxin aka a form of Agent Orange or Roundup. Destroyed my system pretty bad, was blown...

    High HCT - trying to decide whether to get phlebotomy

    I have been in TRT over 20 years, will give you my findings on H&H. Yours are too high, you can go to the blood bank but you will require an override by Administration as you are on TRT and that blood will be tossed. Estimate your numbers being reduced 2 points per visit, every 8 weeks...

    The usual run around

    Greetings to all. Been on TRT for over 20 years; compounded, injectable, transdermal. Was involved in an explosion containing Dioxin, since that moment always in TRT. Unfortunately, all the years of it I became pretty "sensative" to where my H&H became problematic. The usual blood bank trip...

    Understanding my labs

    Understanding my labs

    Never tried Clomid, etc but had been advised earlier this year test phenylpropionate as it's very fast acting and will not effect my H/H plus hits the receptors differently

    Understanding my labs

    My numbers have been much worse, double digits. I have some great docs, but damn they just trash on TRT. Feel like shit, especially being on it over two decades. The unfortunate side is my hemoglobin and hematocrit have become almost sensitive to Test. As soon as I go back on, it rises fast and...

    Understanding my labs

    Greetings. Current labs and I am trying to understand this mess. Been on Test injectable, transdermal, gel, compounds for two decades. Each doctor I have is against TRT (top Endocrinologist, urologist, Internist, cardiologist) and the one that's for it is a bit crazy and reckless (general that...
