    Sexual Symptoms from High RT3?

    I've asked this in another thread, but wondered if others have experienced this with thyroid meds and high RT3. My main question is, has anyone experienced sexual symptoms from high RT3? My main complaints are ED, lack of sensitivity, and severe delayed ejaculation. I've also had some recent...

    T4 helps me sleep. Anyone else?

    Most nights I wake after a good nap. Last night about 2:30 woke right up. Maybe most people wake but return to sleep quickly perhaps. I was up until 4ish. Theanine wasn't enough to go back down. I decided to take T4(50ug) at that time. Takes about an hour I guess but woke sleeping like a baby...

    Time release T3 question

    I’m wondering if anyone has noticed less of an effect from time release T3? I switched to time release T3 this fall from the quick release version and I just recently had a full panel of labs done. To my surprise my rt3 had creeped up to 20.8 (9.2-24.1) and my TSH to 2.6 (.450-4.50). No...

    Anyone felt better without thyroid meds?

    Treating high RT3 with T3. How much is too much?

    I noticed that actual endocrinologists who treat patients for elevated RT3 using Cytomel often prescribe T3 dosages between 10 to 15 mcg per day. Then I see other people who say they get 50+ mcg prescribed. How do you determine what dose to use? Is there a danger taking 25 or 40 mcg?

    Cytomel (liothyronine) shuts you down?

    Guys, does cytomel shut down your natural production of t3 in the body? I just started taking 10 mcg daily to lower a high RT3 and incrrease a low normal t3. Just saw a video stating that minimum dose should be 25 mcg daily as this is what the body produces naturally? They said it was like...

    My Thyroid numbers

    I'm doing great just sharing for the larger discussion that can be had, for others to learn. I've been supplementing with T3 in the 5-10-20mcg once or twice per day the goal being to push my RT3 down a little bit for fatigue. Have tit-rated the dose over the last month. 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...

    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...
