    Hi to anyone who is taking/has taken T3 and T4 thryoid med.

    I have had lots of tests for adrenal and thyroid function (both of which tested VERY LOW) and have been able to build up my adrenals over the last year until I now have sufficient cortisol in my body to start T3 and T4 thyroid med. My specialist has started me on what he calls a 'baby dose' because my system is so sensitive.

    I would like to compare my dosage with that of other people taking this med.

    My question is:

    What dose of T3 and T4 are you on?

    Thanks in advance for your response

    I take both. I have Grave's Disease (hyper thyroid). Had RAI in 1987, thyroid no longer works. I was on T4 for several years & then my body stopped converting it to the much needed T3.

    I'm currently taking 125 MCG Synthroid (T4) once daily & 5 MCG Cytomel(T3) 2 times a day. My body can not handle a higher amount of T3 or I go hyper. I still suffer with fatigue daily tho.

    My TSH is at the very bottom of the range. T4 & T3 show upper levels, so I'm on the max dose.

    Each person is different, so it's hard to compare what may work for you. It's best to start out low dose & work your way up over a period of months. T4 is retained in the body & takes awhile to be converted in your system to T3. T3 works almost instantly & is not retained.

    I am on 2 grains of armour thyroid although my Dr. said if might be better if I lower the armour and supplement with some T3 alone. I feel like my brain works better on this dose, but I am still fatigued and looking for more stamina.

    I'm on Armour Thyroid, 60 mg. daily. Have been for years. Seems to help much better than Synthroid alone.

    I take T3 from a compounding pharmacy. My T4 and TSH were in normal range, but my T3 was 235 (range is 230-430). I had terrible muscle aches, so they worked me up to 75mcg of T3 and finally the muscle aches went away. My T3 now measures at 600! But I don't feel hyperthyroid or anything, and when I lowered my dose a little, the muscle aches came back severely. My doctor says that my body is T3 resistant, which means it is not properly using and/or absorbing the T3, and it could even be making antibodies against the T3. Anyway, I feel great on 75 mcg.
