Need opinions on T4

[Dai Kaioushin]

Hi all there,

I have started a thread earlier where I mentioned that I'm planning to do a cutting cycle with prop-clen-T3. Unfortunately I have to change my plans from cytomel to L-Thyroxin because I couldn't get the stronger thyroid hormone. I have read a lots of thread on both T3 and T4 but I'm confused a bit. That is clear me that T3 is much more stronger than T4. But there was a lot of post on T4 where some of you mentioned that T4 is a crap, it worth nothing, some of you mentioned that T4 is as good as T3 is.

Clear my mind please!

Thx anyway:

Do not use T4 (Synthroid). Use T3 or nothing. You need to get the active form of thyroid hormone.

T4 vs T3

The thyroid gland secretes two types of thyroid hormones, T4 and T3 in a ratio of 80%T4 to 20%T3. Although most of the thyroid hormone in circulation is T4, T3 is the active form. Most active T3 comes from the conversion of T4 to T3, not the 20% the gland delivers.

The main cause of metabolic slowing is a decrease in T3. During dieting, T4 doesn't convert to T3 very well. Cortisol reduces the production of TSH (thyroid stimulating hormone) and it affects the conversion of T4 to T3.

Most of the metabolic slowdown is because of poor conversion of T4 to T3. So giving someone Synthroid (T4) is a waste during dieting, for it won't convert to the active form of T3. In the actual scenario, giving synthroid to the individual will further cause a decrease in the amount of T3 because of a negative feedback loop.

So, one must supplement with T3 (cytomel) to bypass the faulty conversion. That's it in a nutshell.

Sorry Buld0g, I'm Hungarian. If I translate that question into Hungarian, it'll be meaningful. Sorry once again!
