The smallest dosage T3 pill you can get is 5 mcg. I'm suggesting that you start with half (2.5 mcg) of that. You can either try splitting that further into quarters and taking 1/4 (1.25 mcg) in the morning and 1/4 around noon or you can take the entire half at one time.
The pills are so small that it's hard to split them into quarters without ending up with a pile of dust, at which point, you're pretty much sunk, unless you want to play "junkie" and can divide that into 4 equal piles, then eat the dust. You have to have a really good pill splitter to split them in quarters.
Another option is to have 1.25 mcg compounded, but I wouldn't get very many, because you'll be going up before long. Discuss the options with your doctor.
Yes, I do think the body gets used to the T3 like it does the T4; sometimes it might take longer, though because the T3 is more powerful. You've been without it for a long time, so it will take time for your body to adjust.
T3 is in much smaller doses due to its power with it acting so fast.
So a starter dose of T3 is commonly 2.5 mcg.
But because of your past history with intolerance of T3 I think Barb is suggesting splitting that pill in half which would be 1.25 mcg in the morning and 1.25 mg in the early afternoon say 1 to 3 PM.
would you do .125 .125 or 2.5?
do you think the body adapts to taking t3 like it does t4? like you feel junky at first but eventually feel a little better?
It's not the FT4 of 1.5 I'm so worried about; it's the FT3 of only 2.9. That's not nearly enough and explains the "feeling of crap = 9 range 1 - 10".
I know you don't like T3 med; you can't live with it and you can't live without it... That's why I suggested a split of only 2.5 mcg to start, which is very tricky to accomplish.
I hate that t3 stuff. do you think that ft4 of 1.5 is too high? do you see people doing well with a t4 of 1.5?
