How long can you run T3 and at what doses??

  1. Question How long can you run T3 and at what doses??

    Hey guys just was wondering if I could get your opinions on the t3 dosage and if i could possibly run it longer, or if there was any advice on how to go about running t3 with these anabolics. THANKS!!
    Age 22
    2-3 years lifting
    height is 6'2

    Im currently on a cycle of: - Per Week:
    250mg of deca
    500mg of test

    and this is my t3 dosages that i wrote out-

    12.5mcg -7days - EVERY FRIDAY is TAPER dosage. starting 2/10/2012
    25mcg -7days
    50mcg -7days
    75mcg -7days
    100mcg -7days
    75mcg -7days
    50mcg -7days
    25mcg -7days
    12.5mcg -7days

    Any feedback regarding t3 for fatloss will be greatly appreciated!
    Thanks in advance

  2. bump please!

  3. You don't need to taper, studies have shown this. Max dosage of around 75-100, adjust as results are seen. PCT for it if desired from places like NTBM, or kelp for iodine.

    There's plenty of info if you search for it.

  4. Any idea where I can see these studies? sh*t could be way more effective without the taper.

  5. same ide like to see the studies as well because ive always understood tapering is safer

  6. also... if you taper down dont you reduce the chance of a hard weight gain rebound??

  7. Cytomel

    (Liothyrine Sodium )

    This drug is a synthetic T3 hormone . As you may already know, most natural T3 is not produced directly by your thyroid gland, but rather is converted from the T4 thyroid hormone . (8)

    Natural T3 is a regulator of the oxidative metabolism of energy producing substrates (food or stored substrates like fat, muscle, and glycogen) by the mitochondria. The mitochondria, as you will recall from your high school biology class, are usually referred to as the "cell's powerhouses" because they produce ATP. Taking Cytomel (supplemental T3 ) greatly increases the uptake of nutrients into the mitochondria and also their oxidation rate (i.e. the rate at which they are burned for energy), by increasing the activities of the enzymes involved in the oxidative metabolic pathway. Everything is working harder, in other words, and more fuel is needed to supplement this increased work rate. Therefore, as you can guess, taking supplemental Cytomel will increase your body’s energy demands. And if you are in a hypocaloric state, you will begin burning even more fat primarily due to an increase in ATP. This increased ATP causes an increase in overall metabolic activity. (8)(9)This is exactly what we want, and is why we would be taking thyroid hormones like Cytomel in the first place. If you aren’t taking anabolic steroids with your Cytomel , however, your body may start to eat away muscle to provide energy for you to function. Remember mitochondria/ATP aren’t very picky, but they are very efficient. What I mean by this is that they will use whatever is on hand to generate energy for your body to continue functioning…fat, protein , glucose….it doesn’t matter to ATP, as long as there’s something to give them energy. Taking this drug will increase their need to find something to burn to create this energy. Ergo, if we aren’t taking anabolic steroids while taking our T3 , we may lose too much muscle, especially while dieting.

    Thus we can see that there are many advantages to using Cytomel to optimize our metabolic rate. It will also increase your body’s ability to synthesize protein , but from what I’ve seen personally, it acts as a catabolic when it isn’t administered with anabolic steroids . It is often the last thing added into a precontest diet , as it has a reputation for getting rid of the last few percentages of bodyfat…the “sticky fat” as it’s called in bodybuilding …the fat that just doesn’t want to leave you in the last few weeks of dieting. I think this is a poor use for this drug, and that it should be the first thing added into a diet to lose fat, as it will optimize your metabolic rate, which should be done at the outset of a diet , not after the calorie restriction has diminished your thyroid output and you are adding it in simply to replace what was lost.

    Unfortunately, in all of the studies I’ve seen, T3 also increased growth hormone production. (5)(6) As we all know, GH is also a strongly lipolytic compound, and this is another mechanism by which T3 may exert it’s effects, although I suspect this would only be a small percentage of it’s overall effects. This being the case, it has always been somewhat problematic to me to note that when GH and T3 are used together, the increased nitrogen retention normally found with GH use is negated. (7). If you were only using T3 and GH this may be a problem, but as I’ve already stated, you are going to need some anabolic agents if you are using T3 . And as you have read previously, I recommend the veritable anabolic /lipolytic orgy of Insulin , T3 , Anabolic Steroids , GH, and insulin , for 100% maximum results in minimal time

    On the brighter side, and of special note to dieters, administration of T3 has been shown to upregulate the beta 2 receptors in fat tissue. As you know clenbuterol and similar compounds downregulate this receptor, so using T3 with your clen will help stave off or reverse this downregulation. (1)(2)(3)(4). I would still recommend taking your benadryl every third week, though.

    Finally, I would like to address the issue of recovery of your natural thyroid function after you stop taking cytomel . The horror stories of people on permanent thyroid repla***ent just aren’t true. I remember a few years ago, the rumor was circulating that the current Ms.Fitness had permanently shut off her thyroid gland, and was now fat and on thyroid hormone permanently. This is just another horror story based in nothing but conjecture and rumour…the studies I’ve looked at have shown people recovering their thyroid hormone relatively quickly (within months, at most) after going off of several YEARS (!) of thyroid repla***ent therapy (10)(11). I speculate that you can optimize your metabolic rate with Cytomel for 9-10 months a year, and just normalize yourself for 2-3 months (perhaps the winter, when you are mostly covered up), and then go right back on. Some people in the studies I read were on T3 for 30 years and recovered their natural thyroid function within a few months. It is however important to reduce the amount of T3 as you come off of it. I think we can safely spend an athletic career using Cytomel 9-10 months out of the year, and just taking those few months off to normalize ourselves. Is this aggressive? Yes. Unsafe? NO.

    dditionally T3 can be used to treat bipolar disorder in some at high dosages (150mcg+) for periods of time and then they have stopped with no issues

  10. nice write up.

  11. I think the link would be jstor. But if you can a search for endocrinology journal it might work

  12. Thanks alot for the post, so once i hit 75mcg... should i run that 4 weeks? then 100mcg the last week for week 5?

  13. So no taper down at all? Just ending it around 100 right?

  14. yes, is it okay to do this? or will it cause hardcore weight rebound?

  15. bump for answers!
