    My Thyroid numbers

    I'm doing great just sharing for the larger discussion that can be had, for others to learn.

I've lost a few pounds...

    How reliable are free thyroid and total T3 hormone assays (Study Inside)

    I think this is an important discussion point that is not talked about when trying to dial in our thyroids. What are your thoughts/discoveries on this? How reliable are free thyroid and total T3 hormone assays? "Measurement of T3, FT3, and FT4 by the immunoassay methods commonly used by the...

    Low dose T3 (Cytomel) for fatigue

    I'm posting this for reference and information only but would welcome any insights/comments you all may have. In June of 2018 I had blood work done after visiting my TRT doctor regarding fatigue and trouble sleeping. My sex hormones turned out to still be in the same good range that I had been...

    I have three sets of labs at this point and see that my rT3 continues to increase while my t3 and t4 stay on the lower end of optimal. I feel better and some of my symptoms have improved (less dry skin, increase in energy, hair porosity has improved, etc). It was stated that I could get off of...

    Reverse T3 (rT3): Should it be measured in patients with hypothyroidism?

    There is a lot of controversy about whether reverse T3 (rT3) should be measured to assess hypothyroidism. The normal thyroid gland secretes T4 (an inactive precursor), T3 (the active hormone), and reverse T3, a biologically inactive form of T3 that may block T3 from binding to the thyroid...
