Thyroid bloodwork?

[btails]

Quick question,

What bloodwork is needed to confirm T3 is real? And what results correlate to which dosage (ie. 25mcg=? , 50mcg=?)

Thanks

You need to do:
FreeT3
FreeT4
TSH

25mcg T3 ed is just wasted, it's barely a TRT for your thyroid.

go for 37,5mcg or 50mcg.

More than that you will be too catabolic and tired all day long.

Thank you

And what results should correlate to 50mcg?

Thank you

Idealistically it would be helpful if you pulled a few thyroid parameters pre liothyronine to access your levels, e.g., TSH, FT/T4 and FT/T3. You determined your baseline.

Under those circumstances as a baseline, after a few days/week you would anticipate a drop in your TSH and FT/T4 and a rise in your FT3.

Ah too late for that

Today is your lucky day OP.


These are my labs from 50 mcg of US pharmaceutical T3.

2 hours after taking it fasted. I believe 2 hours is around the peak time.


You can use my labs and method as a reference if you want to test your own T3.

Curious, was this your initiating dose or repetitive daily dosing? Understandably, the PK steady state is difficult to measure with liothyronine due to its biological half-life. IIRC, the biological half-life differs between--euthyroid, hypo/hyper.

Thanks.

4 weeks. You can see it suppressed my endogenous T4 production.
