T3 or T4

[Cdn]

Its been years since ive used T3 for fat loss and to rev up metabolism. My question is what is the difference between the two in terms of results and thyroid health?

T3 is stronger then T4. I believe in regards to thyroid health the safer of the 2 would be T4. T4 is more so prescribed to patients.

T3 is the more active form from my reading. T4 gets converted to T3. If your body doesn't have the ability to convert all the T4 then you don't get the benifits of it. That said I take a combination of both.

T3 is much more potent than T4 (about 4x if I recall correctly). Endo's almost always start patients on T4 and then add T3 if necessary. They seem to often employ a combination of the 2 based on bloodwork and symptoms though. A portion of T4 will eventually be converted into T3. There's a ton of variability from person to person that dictates that though.

I personally use both and will factor in t3 usage year round now

T3 is crazy for fat loss. Just make sure to keep the dose moderate and not go too high.

Will do thank you. Doing 25 mcg.

T3 is very strong, T4 I found ineffective. 25-50mcg of T3 will cut you up, just watch you eating because it does make you very hungry... if you are on a cut that is the only issue I have had.

I noticed already. The 25 mcg t3 ive lost pounds in only a few weeks. To much so even. Im going to cut it in half. The t4 I didnt notice much. Did not combine the 2 yet. Want to see how they react on their own first.

T4 is inactive and T3 is active. T4 has a longer half life and T3 has shorter. T4 mainly for thyroid issues or when on GH. T3 is used mainly for cutting in BB but used alone or with T4 in medicine. If you don’t have a thyroid problem don’t mess with t4 unless on gh. T3, taken long enough can shit thyroid down. I always do 6 weeks on 2 weeks off, even when cutting in a pyramid up then down cycle. T3 alone is nothing without diet and cardio.

Great info. Thank you!

what are the pros of taking t3/t4 mix and not just t3?

Keeping your ratios similar to what an euthyroid people have

Also I’m switching thyroid medication to bedtime 4 hours after eating been shown to be better with t4 t3 could keep you up but will give this way a try
