How long does cytomel take to work?

I know synthroid has to build up in your body but I am wondering how long does it take cytomel to work? The dosage of the cytomel 5mcg. I’m not going to post my labs.

If you are taking it in addition to levo, about 3 hours to peak. If you are taking only 5mcg of T3 and nothing else, unless it for depression (not thyroid disease) you probably won't notice any difference as it is such a low dose.

You have to take enough of it for it to 'work'. But, if you don't want to post your labs, we can have absolutely no idea if you are taking enough.

The reason I haven’t yet posted my labs is to wait 2 weeks on it then I will add my updated labs.
