Synthroid is a man-made synthetically manufactured version of T-4/L-thyroxine. The average person produces about 76 MCG/d of T-4/L-thyroxine which is then converted by the liver into the more active T-3/L-triiodothyronine. This is true of the oral T-4/L-thyroxine medications as well. The average conversion rate of T-4 to T-3 is about 30-33%/ MCG. Since the conversion of T-4 to T-3 is dependent upon adequate levels of since and selenium, athletes commonly increase daily intake of these minerals during synthetic T-4/L-thyroxine use.
As is the case with all thyroid hormone drug use, most athletes were noted as wiser to begin at a lower dosage of 100 MCG/d and slowly progress to their chosen dosage. Daily dosages of T-4/L-thyroxine that exceed 400 MCG will not increase metabolic rate beyond what is realized at 400 + MCG/d.
Dosages that were increased too rapidly or that were too high commonly resulted in diarrhea, excessive sweating, rapid heart beat, nausea, vomiting, insomnia and trembling.
T-4 drugs suppress endogenous thyroid hormone production significantly. After discontinuance, most athletes experienced a metabolic lag period of 3-15 days before thyroid function rebound occurred. Interesting fact is that most monitored athletes experienced a 120-130 % increase in endogenous thyroid hormones at that point. And some maintain that level permanently.
The noted positive physiological effects of reasonable dosages of thyroid hormones included:
*Increased protein synthesis rate. *Increased rate of fat oxidation.
*Increased sensitivity of receptors for androgens, Insulin, GH, IGF-1, PGE-1, PGF-2, Clenbuterol, Ephedrine, Creatine, and others.
*Increased metabolization of proteins, carbohydrates, fats and micronutrients. *Increased metabolic rate and calories expenditure. *Enhanced oxygen consumption by most body tissues *Improved recovery time.
The noted negative physiological effects of excessive dosages of thyroid hormones included:
*Loss of lean mass tissue.
*Increased heart rate and palpitations.
Thyroxin T4 is ideally used with Eutropin (HGH) as it has been shown that T4 level are reduced during the use thereof.
The great thing about T4 is that it is more difficult to overdose it. T4 is converted to T3 by your body and is safer to use than T3 itself. The reason being is that your body will convert T4 to T3 and of course, your body will not overdose itself and will only convert the optimum amount to T3.

Just a thought:
It is possible to hypothesise that when on HGH your body will use more T3 and his may contribute to the fat burning effect experienced. More T4 is therefore converted to T3 hence the reduction in T4 levels seen when on HGH. As stated, this is merely a hypothesise and no medical evidence exists proving this but it is an interesting thought.
