Thyroid Hormone + Growth Hormone – If You Aren’t Using T4 with Your GH, You’re Not Doing It Right
July 23, 2006*By*Anthony Roberts
Quite some time ago, I wrote a book on Anabolics, and since then, I’ve received quite a bit of feedback on it. Some of the information contained in the book is based on the 50-60 profiles I completed for Steroid.com’s main page. As a result, I get feedback on certain portions of the book from people who have read them online.
When someone takes the time to send an e-mail to Steroid.com or AnabolicBooks LLC, they’re screened, and eventually some of them make their way to my e-mail account. AnabolicBooks LLC is publisher- a little known fact is that my book is actually wasn’t edited by me, nor do I own the rights to any of it. When they forward an e-mail to me, I typically consider it very carefully, and reply to the original sender. If amendments or additions are useful for anything I’ve previously written (readers frequently send me recently published studies), I typically reply and thank the person for their help.
This time, something odd happened. I was forwarded an e-mail from AnabolicBooks, and the reader seemed to know what he was talking about, but (I thought) mistaken about interactions between*Growth Hormone*and Thyroid medication. I took a look at the e-mail, and knew that I could quickly find a study that I had saved previously, to send to the reader, to verify that the claims in my work on GH were sound.
In this particular case- James Daemon, PhD- was the reader, and was correct in his assessment of the interaction between thyroid hormone and*Growth Hormone. And, in direct contradiction, so was I. Thyroid medication decreases the anabolic effect of Growth Hormone. And it increases it.
Huh?
There’re some leaps here, because research in some of the necessary areas is sketchy (or not done yet), but if you read the entirety of this article, you’ll learn how to get a significantly more gains from Growth Hormone, for pennies a day, by the addition of a readily available (and cheap) addition to it. And yeah, it’s a drug you can get anywhere on the ‘net, very easily. And no, it’s not a steroid.
In fact, I’ll go so far as to say you’re throwing away a substantial portion of your gains from growth hormone if you are not using this drug with it.
Ok…I’ll explain things a bit further. First, a brief explanation of Thyroid Hormone as well as Growth Hormone may be necessary.
Your thyroid gland secretes two hormones that are going to be of primary importance in understanding Thyroid/GH interaction. The first is thyroxine (T4) and the second is triiodothyronine (T3).*T3*is frequently considered the physiologically active hormone, and consequently the one on which most athletes and bodybuilders focus their energies on. T4, on the other hand, is converted in peripheral tissue into T3 by the enzymes in the deiodinase group, of which there are three types- the three iodothyronine deiodinase either catalyze the initiation (D1, D2) or termination (D3) of thyroid hormone effects. The majority of the body’s T3 (about 80%) comes from this conversion via the first two types of deiodinase, while conversion to an inactive state is accomplished by the third type.
It’s important to note that not all of the body’s T4 is converted to T3, however- some remains unconverted. The secretion of T4 is under the control of Thyroid Stimulating Hormone (TSH) which is produced by the pituitary gland. TSH secretion is in turn controlled through release of Thyrotropin Releasing Hormone which is produced in your hypothalamus. So, when T3 levels go up, TSH secretion is suppressed, due to the body’s self regulatory system known as the “negative feedback loop” . This is also the mechanism whereby exogenous thyroid hormone suppresses natural thyroid hormone production. However, it should be noted that thyroid stimulating hormone (like all other hormones) can not work in a vacuum. TSH also requires the presence of*Insulin*or*Insulin-like Growth Factor to stimulate thyroid function (1) When thyroid hormone is present without either insulin or*IGF-1, it has no physiological effect (ibid).
