T3 dosage spacing throughout the day.

**Atomini** · 07-09-2007, 11:58 AM

Just wondering if i'm doing this properly...

7:30AM - First dose, 40mcgs

12:00AM - Second dose, 40mcgs

2:00PM - Final dose, 40mcgs

Should this be more spread out evenly? What's the general consensus on how spread apart these doses should be?

The halflife of T3 is 2.5 days, so I don't see the whole deal everyone talks about where it should be as spread out as possible to keep stable blood levels. Blood levels would be stable anyways, right?

i take my whole dose first thing in the morning

**Atomini** · 07-09-2007, 12:10 PM

Yeah I was wondering if I should just go ahead and do that too. Would be a heck of alot more convenient. Might burn fat more efficiently that way, too.

Bump...

I took the whole thing in the AM as well.

At the peak of T3 cycle I'm taking 150mcg. I tried takign that all at once and my heart rate was off the charts.

Considering it has a 4 hour half life I have had the best results breakign it up through out the day. That way your metabolism is high throughout the day. just do not take it before bed as you will feel restless and hot all night long.

FOUR hours? So why am I reading all kinds of places that it's half life is 2.5 days?

I'll attempt to take all of my dosages at once in the morning tomorrow just to see how that goes.

Thus far my body temp has been floating around the 98.2 range. I took my temperature everyday for a week before starting my T3, and I found my natural body temp range is around the 97.5 range.

Please show me a source sayign 2.5 days... I have taken T3 on and off for 7 years and I can assure you its not 72 hours. A quick google search brought back this "While thyroxine has a half life in the body of about 7 days, triodothyronine (T3) has a half-life of about 10 hours. " from http://www.ithyroid.com/hypot_treatments.htm

"Half life of T4 is 1 week; T3 half life is 1 day." from http://www.endocrinology.med.ucla.edu/Thyroid.htm

T3, on the other hand, has a half-life of about a day. People on T3 sometimes feel its effects within minutes after taking it.
from http://www.altsupportthyroid.org/t3.php

All of thse are longer then 4 hours but NO where NEAR the 72 hours you mentioned.

In my personal opinion I get the best results breaking up the larger doses throughout the day with of course the proper diet and workout.

I'll have to PM you where I got the info, since it's connected to my source.

And I also read the 2.5 day half life in William Llewelyn's Anabolics 2006, I believe.

**Maximus_Pecs** · 07-09-2007, 08:29 PM

Check your PM bro

**BuffDJ** · 07-09-2007, 09:24 PM

The half life of cytomel is a day and a half. Take it first thing in the morning with breakfast your good to go.

regardless the half-life, you take it all in the morning on an empty stomach, its an apsortption thing

**slimsc** · 07-10-2007, 01:12 AM

morning guys...

i sure wish i could take a higher dose of t3... anything over 25mcgs and i start havening uncontrollable anxiety attack...

i am not talking a little restlessness!!!

**Atomini** · 07-10-2007, 08:20 AM

Anxiety? That sounds like something Clen would do.

**theflyzman** · 07-10-2007, 09:17 AM

Yes. I have read in anabolics 2007 that it should be broken up through out the day, and to never go over 100MCG or you could end up with a thyroid problem for the rest of your life!!!!

That's accurate, hence dosing throughout the day is irrelevant:

The person who quoted 4hrs may have confused half-life with absorption, as T3 is almost totally absorbed, 95% in 4hrs...this stat is also under the Pharmacokinetics.
