How long does thyroid hormone clearance actually take?

[JohnBoy2000]

Synthetic T4.

Half life is 7 days.

At 25 mcg, how long could one expect actual full clearance to take?

It doesn't have to reach steady-state for say, 4 or 5 half lives pass such that the drug is actually completely absent from the system.

i.e. single dose, full clearance.

Up to a month?

5 days out from dose and it has still elevated my heart rate, and other physiological effects are still apparent.

I’d say 30 days give or take.

Yeah, 25 mcg, who would have thought?

This shit is seriously fucking with my nervous system.

As in, super edgy/nervous constantly, goes into overdrive in public.

To the point of borderline psychotic rage.

Some little wanna be bad boy just walked into me on my way home just now.
It took every ounce of self discipline not to choke slam him in the street - I was watching my entire future and potential career go up in flames before my eyes if I did that.

Just sucked it up, turned and walked away.

....

I had been doing perfectly fine previous to dosing T4 last Tuesday at 9 am; now it's Sunday at 12 pm and I'm still feeling the effects just as powerfully.

.....

It would seem that yes, I'll be looking at about a month of extreme behavior monitoring and being careful where I go and when.
