Do you have experience using T3 or T4?
What was you're experience? What was the reason you used it?

Do you have questions about T3 or T4 usage?

This thread will share information regarding the usage of these thyroid hormones.
Perhaps some of the most misconceived drugs out there in our world. Many turn to the drugs without proper information/education.

Post your thoughts here on the recreational use of T3 or T4.

About Thyroid Hormone.

A hormone, especially thyroxine or triiodothyronine, produced by the thyroid gland.
The American Heritage® Medical Dictionary Copyright © 2007, 2004 by Houghton Mifflin Company. Published by Houghton Mifflin Company. All rights reserved.

Thyroid hormone
an iodine-containing compound secreted by the thyroid gland, predominantly as thyroxine (T4) and, in smaller amounts but four times more potent, triiodothyronine (T3). These hormones increase the rate of metabolism; affect body temperature; regulate protein, fat, and carbohydrate catabolism in all cells; maintain growth hormone secretion, skeletal maturation, and the cardiac rate, force, and output; promote central nervous system development; stimulate the synthesis of many enzymes; and are necessary for muscle tone and vigor. Derivatives of thyronine, T4 and T3, are synthesized in the thyroid gland by a complex process involving the uptake, oxidation, and incorporation of iodide and the production of thyroglobulin, the form in which the hormones apparently are stored in thyroid follicular colloid. After the proteolysis of thyroglobulin, T4 and T3 are released and transported in the blood in strong, but noncovalent, association with certain plasma proteins; T4 accounts for approximately 90% of iodine in circulation, and T3 for 5%. All phases of the production and release of T4 and T3 are regulated by the thyroid-stimulating hormone secreted by the anterior pituitary gland. Production of thyroid hormones is excessive in Graves' disease and toxic nodular goiter (Plummer's disease), diminished in myxedema, and absent in cretinism. The normal 6- to 7-day half-life of T4 in blood is reduced to 3 or 4 days in hyperthyroidism and extended to 9 or 10 days in myxedema. T3 has a normal half-life of 2 days or less and, like T4, is metabolized most actively in the liver. Pharmaceutic preparations of thyroid hormones extracted from animal glands and the synthetic compounds levothyroxine sodium and liothyronine sodium are used as replacement therapy in patients with hypothyroidism. The dosage is initially low and is gradually increased to the optimal level based on the patient's clinical response and tests of the findings on thyroid function studies. Overdosage or a rapid increase in the dosage may result in signs of hyperthyroidism, such as nervousness, tremor, tachycardia, cardiac arrhythmia, and menstrual irregularity.

What Is T3?


T3 is a naturally occurring thyroid hormone that is important for normal metabolism. In some individuals, the body may not produce enough T3for some reasons. In these cases, the affected individuals must take Liothyronine, a T3 hormone used to replace the natural thyroid hormone of the body.

What is T3 Liothyronine? Also known as T3, liothyronine plays an important role in the chemical makeup that controls almost every physiological process in the body, including growth, metabolism, and physical development. T3 hormone also plays a vital function in bone growth and development as well as in the production of chemicals in the central nervous system called neurotransmitters. In addition, T3 has a direct effect on embryonic and fetal growth. As a powerful hormone, T3 acts on the body to boost basal metabolic rate, protein synthesis and sensitivity to catecholamines. It promotes proper growth and maturation of all body cells by regulating carbohydrate, protein, and fat metabolism, which in turn affects how cells use energy.

T3 (liothyronine) improves your body’s energy and oxygen utilization, which is important to preserve life. Liothyronine is a powerful thyroid hormone that is necessary for functioning of almost every major organ in the body except the spleen and the testes. In contrast, T4 or thyroxine hormone, is much less active, and has to be converted to T3 when the body needs it.

What is T4.

Thyroxine is a hormone the thyroid gland secretes into the bloodstream. Once in the bloodstream, thyroxine travels to the organs, like the liver and kidneys, where it is converted to its active form of triiodothyronine. Thyroxine plays a crucial role in heart and digestive function, metabolism, brain development, bone health and muscle control. It affects almost all of the body's systems, which means proper thyroxine levels are vital for health. This is why many doctors will test T4 levels along with the more common T3 levels when testing for thyroid disorders.

Having too little thyroxine or too much thyroxine can cause health problems. If your body releases too much thyroxine, you will suffer a condition called thyrotoxicosis. This can cause a goiter, which is a swelling of the neck because of an enlarged thyroid gland. Thyrotoxicosis can also cause menstrual irregularities, an increase in bowel movements, weight loss, heat intolerance, fatigue and irritability. Thyrotoxicosis is commonly caused by hyperthyroidism, tumors in the thyroid gland or thyroid inflammation.
The body can also produce too little thyroxine, a condition known as hypothyroidism. Low thyroxine levels cause problems with development if it occurs when an individual is young. In adults, thyroxine deficiency will lower the metabolic rate, causing weight gain, memory problems, infertility, fatigue and muscle stiffness.

I've never had a desire to touch any thyroid drugs myself. I have no problems getting lean enough with my diet, training, and things like GW and SR9009 to aid me along the way

Ive never really noticed anything spectacular honestly. Anything Ive done with t3 or could do with t3 is accomplished just as easy with diet like you said.

I would say the one big difference for me is the t3 allows a much faster and drop in fat. It also allowed me to focus on weight training way more than cardio in the past. The only other benifit is I felt a little better while dieting because your allounces in food are slightly higher depending on where you dose at.

Things I don't like....
Well your sweat will straight stank. And you will sweat a ton. You get kind of a shaky dizzy feeling for the first week or so.
Muscle bellies go flat. Makes you feel pretty unproductive in the gym. You get winded easy.
Hmmm. Cant think of much else on top of that.

I like t3 personally but I wouldnt consider anything above 50mcg-75mcg. Your body will produce 20-30mcg naturally.

Rebound isnt a huge issue honestly. That's one thing that is just total bullshit in my opinion. The impact on the thyroid and the "rebound effect" Is so greatly exaggerated its ridiculous. I do happen to have a close friend from back home who is an endo. Il try to get him to sign up here at some point. The dude is a wealth of info.

GW and SR9009 are easilly comparable I think. Depending on what dose your comparing it too. Like I said you get kind of a weird shay feeling on t3, you go flat. You feel like poo and smell like poo. Definitly keep that in mind. You will feel a lot better the sarms route.

I take T4 daily 125 mcg as prescibed too me im hypo I also take t3 on my own but only 25 mcg this is not perscibed but there still working on my dose and 125 isnt enough when I add the t3. i feel and function better and my metabolism is normal but I dont cycle the dosage up for fat loss I take it in a physiologic amount for treatment

How long you been doing it for? Did the flatness effects and all that ever where off? That's what I cant get around. Even around 50mcg t3 only I still get it.

 

[Gymjunkie38]

50 is inducing a hyper state if your burning fat your going too go flat reffed once a week with a few hundred grams of carbs youll stay oit of the catabolic range but remeber I take what I need 25 mcg is a physiologic amount 50 is double and im only doing that cause my retarded dr raises my dose of t4 25 mcgs every 3 months or so and my TSH is still like 4 something not barely moving my dosage is far too low for me . hes one of those dummys that treat everyone exactly the same its alot too do with amount of lean weight with t4 hes used too hypo middle age wemon at 160 lbs 20 percent bodyfat not 270 lb bodybuilder at 8 percent bodyfat

I have a bunch of t3 from a buddy a while back. I don't even know why I accepted it. I'll probably never use it. Shit scares me.

It's not too bad man. It's tally got a lot of horror stories to it but in reality it's not such a terrible thing. Your smart enough to where you could make good use of it I'm sure and be ok.

It's definitely one of those things you end up with a ton of at some point haha. I have a shit load of it sitting around. Most of it I don't even remember where it came from. I remember xeno gave me a bottle of t3/t4 25/100's

i completely agree... they are just as if not more effective yet far safer and far more sustainable... i dont like to do any sort of tampering with thyroid whatsoever... just the thought of it makes me cringe honestly...
