Hi, Viktoriia! I seen you've already signed up for access to the ladies forum. *Admin* stays very busy but will get you fixed up as soon as possible.
I don't really use thyroid meds or Clenbuterol, so I'm not going to post an answer.
Welcome to forum, we are glad you're here! :)
SHORT ANSWER:
Whenever there is a choice, go with T3. The only time one should take T4 is when T3 is inaccessible.
LONG ANSWER:
TSH goes straight to the thyroid gland where it triggers the production of thyroglobulin - a multifaceted protein. The thyroglobulin joins up with four molecules of iodine to produce the thyroid hormone T4, or thyroxine...note the 4 molecules is where it gets its name.
Approximately 94 percent of the hormone made in the thyroid gland is T4. The remaining 6 percent is triiodothyronine (T3), named for its three molecules of iodine.
Although the thyroid gland secretes only a little T3, it is the most active form in the body. Consequently, T4 must be converted to T3 before the body can use it. Most of this conversion happens in the liver, but also takes place in cells of the heart, muscle, nerves, and gut. These cells convert T4 to T3 with an enzyme called tetraidothyronine 5’ deiodinase, which removes one molecule of iodine.
Initially, only 60 percent of T4 is converted into usable T3. Then 20 percent becomes reverse T3 (rT3), an inactive form the body cannot use. Later, another 20 percent of T4 can be converted to T3 by healthy gut bacteria in the small intestine. I said can be because the amount of friendly flora present is a major factor.
This is also why the ratio for taking T4 to T3 is often 4:1 respectively. Lastly, there is no reason the ramp T3 dosages up or down, as has been the custom of many.
Best to you.
