T4, any experiences?

[ajdos]

Has anyone had any personal experience with T4? I've been doing research on it, but I like to hear from peeps who've actually tried things first.

I lost about 25lbs on t-3 and clen in 8 weeks just watch the dose and start low to see how you respond read everything you can find on it so you dont do any damage to your thryoid good luck and post your results

Is there any point to using T4 instead of T3? As far as I can tell, it's just a matter of taking more due to conversion. So it's more difficult to 'overdose' and easier to 'underdose'.

Are there any other benefits? Why not just use T3?

Overall health Armour would be the best. It is a combination of T4 and T3. T3 is the metabolically active thyroid hormone and should be supplemented during strict dieting. Pyramid dosed a few times and currently on 30mg ed to counterbalance HGH use. The body adjusts to added HGH by reducing conversion to T3 to normalize metabolism.

"The thyroid gland secretes mostly T4 and very little T3. Most of the T3 that drives cell metabolism is produced by action of the enzyme named 5'-deiodinase, which converts T4 to T3. (We pronounce the "5'-" as "five-prime.") Without this conversion of T4 to T3, cells have too little T3 to maintain normal metabolism; metabolism then slows down. T3, therefore, is the metabolically active thyroid hormone. For the most part, T4 is metabolically inactive. T4 "drives" metabolism only after the deiodinase enzyme converts it to T3.

Another enzyme called 5-deiodinase continually converts some T4 to reverse-T3. Reverse-T3 does not stimulate metabolism. It is produced as a way to help clear some T4 from the body.

Under normal conditions, cells continually convert about 40% of T4 to T3. They convert about 60% of T4 to reverse-T3. Hour-by-hour, conversion of T4 continues with slight shifts in the percentage of T4 converted to T3 and reverse-T3. Under normal conditions, the body eliminates reverse-T3 rapidly. Other enzymes quickly convert reverse-T3 to T2 and T2 to T1, and the body eliminates these molecules within roughly 24-hours. (The process of deiodination in the body is a bit more complicated than I can explain in this short summary.) The point is that the process of deiodination is dynamic and constantly changing, depending on the body's needs.

Under certain conditions, the conversion of T4 to T3 decreases, and more reverse T3 is produced from T4. Three of these conditions are food deprivation (as during fasting or starvation), illness (such as liver disease), and stresses that increase the blood level of the stress hormone called cortisol. We assume that reduced conversion of T4 to T3 under such conditions slows metabolism and aids survival.

Thus, during fasting, disease, or stress, the conversion of T4 to reverse-T3 increases. At these times, conversion of T4 to T3 decreases about 50%, and conversion of T4 to reverse-T3 increases about 50%. Under normal, non-stressful conditions, different enzymes convert some T4 to T3 and some to reverse-T3. The same is true during fasting, illness, or stress; only the percentages change--less T4 is converted to T3 and more is converted to reverse-T3."

I'm on t-3 and clen. I am on a low carb high protein diet since I finished my last bulking cycle. I must say, I like the results....except for the shakes.,
