T3: A complete guide to cycling T3 and how it works

[DocToxin8]

I was thinking about using T4, have tried it just as an experiment a couple of times, noticed that 200mcgs caused me to go from freezing with a lot of clothes on (winter time) to using a t shirt and sweating in a couple of hours.
This only happened the first time I tried it tough, (I often have very high T4 and high TSH "naturally" on blood tests, probably influenced by AAS)

But, I don't need it for cutting really. I was thinking about the fact that it should increase protein synthesis as well as breakdown, and with a blast that includes slin it could perhaps increase anabolism and fat loss at the same time.

I am however more skeptical about T4 than T3 due to its long half life, and whether that would affect recovery.
(I've seen studies on people wrongly put on T4 for up to 20 years and they all recovered, so I'm not dreading any permanent shut down, but weeks or months of feeling bad)


But more importantly, does thyroid meds have any noticable function in regards to gaining muscle, or is it just a fat loss aid in your experience?

What are your FT4/3 levels? Total levels don't matter. Your TSH is probably on the high side due to environmental stimuli (cold climate).

Imo if your thyroid is already high is not worth it. I have been on 150mcg LT4 and it didn't affect my FT4/3 at all, that's why I use 50mcg T3 (for hypothyroism). Still I feel cold without progesterone from HCG (or Tren!).

On my last blood work just a week ago it FT4 and TSH were pretty normal.
Other times TSH have been above (just) or near the upper reference range, so have FT4. Many times FT3 were skipped, so maybe there's a conversion issue, but when it has been checked it has been within range, not
Low and not that high, I'll see if I have more blood were both were tested.

But I thought it was very strange the first time I tried T4, since I got elevated body temp with 200mcg within hours. I thought it would take
Much longer. The only couple of times I've tried it since has been at below 200mcg or split dose, and haven't noticed that effect.

But if it's only for fat loss I'm not that interested.
Maybe later.

The there's the matter of T4s long half life, I'm afraid it would cause much more prolonged "lowish" levels after quitting than T3.
