but If i have NO thyroid gland(its dead) and im on 200mcg of Synthroid as a prescription ED... My metabolism cannot slow down significantly... is that right?

False. Since Synthroid is basically T4, You could enter a situation where you do not convert the T4 to T3. Since T3 is the more active hormone, if this situation occured you would have a lowered metabolism. This is called Wilson's Syndrome. Here is a link.
If you are having to resort to 200mcg of t4, I'd say look for something else that is more effective. Dale pretty much nailed it.

That is a lot of T4, obviously it isn't converting very well.

But that only converts to about 50mcg of T3...so I don't think that's necessarily a high dose of T4.
Average maintenance doses for those having completed growth and puberty is 1.6mcg/kg of bodyweight.

I think the point he's making ff is that there are probably better options if he's having to take 200mcg. But I agree, in the big scheme of things, it is not that much.

Personally, I would just get T3. Keep in mind I am saying that without knowing your total situation.

I see people beint put on 25mcg and no more, so to me it is high. Like anything it sounds like it depends on how friendly your specialist is.
