Using T3 cytomel for Excellent Weight Loss

T3 (cytomel)

 

Ilosing-weightt has been over 100 years since the discovery by Magnus-Levy that thyroid hormones play a central role in energy homeostasis, and 75 years since the hormones were first used for weight loss. Despite this great length of time, the precise mechanisms by which thyroid hormones exert their calorigenic effect are not completely characterized, and still actively debated. Despite numerous clinical studies having shown that the administration of thyroid hormone induces weight loss, it is not currently indicated as a weight loss agent. This is probably due to the number of side effects observed during thyroid hormone use at the relatively high doses used in the majority of obesity treatment studies. These deleterious effects include cardiac problems such as tachycardia and atrial arrhythmias, loss of muscle mass as well as fat, increased bone resorption and muscle weakness. Nevertheless, thyroid hormones, particularly triiodothyronine (T3) are a mainstay in the arsenal of drugs used by bodybuilders for fat loss. The widespread underground use of T3 warrants an understanding of its mechanism of action, as well as a knowledge of how it is most effectively and safely used, with an eye to minimizing side effects.

Thyroid Function and Physiology

Before jumping right into a discussion of the use of thyroid hormone for fat loss, a little review of thyroid function and physiology might be in order. The thyroid gland secretes two hormones of interest to us, thyroxine (T4) and triiodothyronine (T3). Cytomel is considered the physiologically active hormone, and T4 is converted peripherally into T3 by the action of the enzyme deiodinase. The bulk of the body’s T3 (about 80%) comes from this conversion. 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 the hypothalamus. This is analogous to testosterone production, where GnRH from the hypothalamus causes the pituitary to release LH, which in turn stimulates the testes to produce testosterone.

In addition to Cytomel, it has recently been recognized that there exist two additional active metabolites of T3: 3,5 and 3,3′ diiodothyronines, which we will collectively call T2. Studies have shown that 3,3′-T2 may be more effective in raising resting metabolic rate when hypothyroid subjects are treated with T3, than when normal (euthyroid) subjects are given Cytomel. Therefore in normal subjects 3,5-T2 may be the principal active metabolite of T3 (1)

Like the hypothalamic-pituitary-gonadal axis, the thyroid gland is under negative feedback control. When T3 levels go up, TSH secretion is suppressed. This is the mechanism whereby exogenous thyroid hormone suppresses natural thyroid hormone production. There is a difference though between the way anabolic steroids suppress natural testosterone production and the way T3 suppresses the thyroid. With steroids, the longer and heavier the cycle is, the longer your natural testosterone is suppressed. This is not the case with exogenous thyroid hormone.

An early study that looked at thyroid function and recovery under the influence of exogenous thyroid hormone was undertaken by Greer (2). He looked at patients who were misdiagnosed as being hypothyroid and put on thyroid hormone replacement for as long as 30 years. When the medication was withdrawn, their thyroids quickly returned to normal.

Here is a remark about Greer’s classic paper from a later author:

“In 1951, Greer reported the pattern of recovery of thyroid function after stopping suppressive treatment with thyroid hormone in euthyroid [normal] subjects based on sequential measurements of their thyroidal uptake of radioiodine. He observed that after withdrawal of exogenous thyroid therapy, thyroid function, in terms of radioiodine uptake, returned to normal in most subjects within two weeks. He further observed that thyroid function returned as rapidly in those subjects whose glands had been depressed by several years of thyroid medication as it did in those whose gland had been depressed for only a few days” (3)

These results have been subsequently verified in several studies.(3)(4) So contrary to what has been stated in the bodybuilding literature, there is no evidence that long term thyroid supplementation will somehow damage your thyroid gland. Nevertheless, most bodybuilders will choose to cycle their T3 (or T4 which in most cases works just as well) as part of a cutting strategy, since T3 is catabolic with respect to muscle just as it is with fat. As previously mentioned, long term T3 induced hyperthyroidism is also catabolic to bone as well as muscle.

The proviso about T4 vs T3 for weight loss alluded to above needs some elaboration. There have been a number of studies that have shown that during starvation, or when carbohydrate intake is reduced to approximately 25 to 50 grams per day, levels of deiodinase decline, hindering the conversion of T4 to the physiologically active T3.(5) From an evolutionary standpoint this makes sense: during periods of starvation the body, teleologically speaking, would like to reduce its basal metabolic rate to preserve fat and especially muscle stores. However, a recent study demonstrating the effectiveness and safety of the ketogenic diet for weight loss recorded no change in circulating T3 levels.(6) So this issue not completely settled. Nevertheless, persons contemplating thyroid supplementation during ketogenic dieting might prefer Cytomel over T4 since the bulk of the research does suggest a decline in the peripheral conversion of T4 to T3 during low carb dieting.

Now that we have reviewed a little about thyroid function, let’s consider just how it is that thyroid hormone exerts its fat burning effects.

Increased Oxidative Energy Metabolism while using Cytomel

 

Thyroid hormone has long been recognized as a major regulator of the oxidative metabolism of energy producing substrates (food or stored substrates like fat, muscle, and glycogen) by the mitochondria. The mitochondria are often called the “cell’s powerhouses” because this is where foodstuffs are turned into useful energy in the form of ATP. T3 and T2 increase the flux of nutrients into the mitochondria as well as the rate at which they are oxidized, by increasing the activities of the enzymes involved in the oxidative metabolic pathway. The increased rate of oxidation is reflected by an increase in oxygen consumption by the body.

T3 and T2 appear to act by different mechanisms to produce different results. T2 is believed to act on the mitochondria directly, increasing the rate of mitochondrial respiration, with a consequent increase in ATP production. T3 on the other hand acts at the nuclear level, inducing the transcription of genes controlling energy metabolism, primarily the genes for so-called uncoupling proteins, or UCP (see below). The time course of these two actions is quite different. T2 begins to increase mitochondrial respiration and metabolic rate immediately. T3 on the other hand requires a day or longer to increase RMR since the synthesis of new proteins, the UCP, is required (1).

There are a number of putative mechanisms whereby T2 is believed to increase mitochondrial energy production rates, resulting in increased ATP levels. These include an increased influx of Ca++ into the mitochondria, with a resulting increase in mitochondrial dehydrogenases. This in turn would lead to an increase in reduced substrates available for oxidation. An increase in cytochrome oxidase activity has also been observed. This would hasten the reduction of O2, speeding up respiration. These and a number of other proposed mechanisms for the action of T2 are reviewed by Lannie et al.(7)

What is the fate of the extra ATP produced during hyperthyroidism? There are a number of ways by which the increased ATP promotes an increase in metabolic activity, including the following:

Increased Na+/K+ATPase. This is the enzyme responsible for controlling the Na/K pump, which regulates the relative intracellular and extracellular concentrations of these ions, maintaining the normal transmembrane ion gradient. Sestoft(7) has estimated this effect may account for up to to 10% of the increased ATP usage.

Increased Ca++-dependent ATPase. The intracellular concentration of calcium must be kept lower than the extracellular concentration to maintain normal cellular function. ATP is required to pump out excess calcium. It has been estimated that 10% of a cell’s energy expenditure is used just to maintain Ca++ homeostasis. (1)

Substrate cycling. Hyperthyroidism induces a futile cycle of lipogenesis/lipolysis in fat cells. The stored triglycerides are broken down into free fatty acids and glycerol, then reformed back into triglycerides again. This is an energy dependent process that utilizes some of the excess ATP produced in the hyperthyroid state (8). Futile cycling has been estimated to use approximately 15% of the excess ATP created during hyperthyroidism (8)

Increased Heart Work. This puts perhaps the greatest single demand on ATP usage, with increased heart rate and force of contraction accounting for up to 30% to 40% of ATP usage in hyperthyroidism (9)

Mitochondrial Uncoupling shown from T3

 

As mentioned, the mitochondria are often characterized as the cell’s powerhouse. They convert foodstuffs into ATP, which is used to fuel all the body’s metabolic processes. Much research suggests that T3, like another much more potent agent DNP, has the ability to uncouple oxidation of substrates from ATP production. T3 is believed to increase the production of so called uncoupling proteins. Uncoupling protein (UCP) is a transporter family that is present in the mitochondrial inner membrane, and as its name suggests, it uncouples respiration from ATP synthesis by dissipating the transmembrane proton gradient as heat. Instead of useful ATP being produced from energy substrates, heat is generated instead. There are conflicting studies about the importance of T3 induced uncoupling. Animal studies have demonstrated an actual increase in ATP production commensurate with increased oxygen consumption as we discussed above. Other studies in humans have shown that in fact uncoupling in skeletal muscle does occur. This would contribute to T3 induced thermogenesis, with a resulting increase in basal metabolic rate.(10)

To make up for the deficit in ATP production (as well as provide fuel for the extra ATP production discussed above) more substrates must be burned for fuel, resulting in fat loss. Unfortunately, along with the fat that is burned, some protein from muscle is also catabolized for energy. This is the downside of T3 use, and the reason many people choose to use an anabolic steroid or prohormone during a T3 cycle to help preserve muscle mass. Studies have shown this to be an effective strategy (11). (Muscle glycogen is also more rapidly depleted, and less efficiently stored during hyperthyroidism. This may account for some of the muscle weakness generally associated with T3 use.)

ayurvedic-weight-lossCountering T3 induced muscle loss with anabolic steroids or prohormones makes sense from a physiological viewpoint as well. Thyroid hormone muscle protein breakdown is mainly mediated via the so-called ubiquitin-proteasome pathway. (12). (There are several independent metabolic pathways of protein breakdown in the body. For instance, another pathway, the lysosomal pathway, is responsible for the accelerated rate of muscle protein breakdown during and after exercise.) Testosterone administration has been shown to decrease ubiquitin-proteasome activity. (13) So anabolic steroids specifically target the muscle protein breakdown process stimulated by T3.

What may not be an effective strategy to maintain muscle mass during a T3 cycle is the use of exogenous growth hormone (GH). Studies have shown that when GH and T3 are administered concurrently, the increased nitrogen retention normally associated with GH use is abolished. This has been attributed to the observation that T3 increases levels of insulin like growth factor binding protein, reducing the bioavailability of igf-1 (14). Nevertheless, GH has fat burning properties independent of igf-1, so using GH with T3 would act additively to speed fat burning, but with little if any preservation of lean body mass. So again, if GH is used in conjunction with T3, anabolic steroid/prohormone use would be indicated.

A step by step beginners guide to bodybuilding peptides

CJC-1295

A step by step beginners guide to bodybuilding peptides

You are on this site because you have heard of and want to become more familiar with Growth Hormone Releasing Peptide (GHRP) and/or Growth Hormone Releasing Hormone (GHRH). These 2 materials administered can give you an increased quality of life in ways of anti-aging, muscular hypertrophy, fat loss, injury repair, higher bone density, and better sleep.

GHRP can be used on its own to increase our natural Growth Hormone (GH) pulse release from the Pituitary Gland in the brain. GHRP dosed in conjunction with GHRH will amplify our growth hormone release significantly to gain maximal benefit.

There are various types of GHRH‘s. The only GHRH to consider is tetra-substituted CJC-1295 / CJC-1295(without DAC) / mod-GRF(1-29). They are all the same thing but with a different name. They come in vials ranging in material weights measured in milligrams (mg) consisting of a solid freeze-dried (lyophilized) substance.

There are various types of GHRP‘s. GHRP-6, GHRP-2, Hexarelin, and Ipamorelin. The differences between them are potency and side effects. GHRP-6 is very potent and makes you quite hungry. GHRP-2 is potent and can slightly affect your sleep somewhat. Hexarelin is very potent but you can desensitize from higher dosages. Ipamorelin is potent with the minimalist side effects of all 4 GHRP’s.

Peptides are dosed via a regular 1mL needle syringe typical to what a diabetic would use. It is administered Subcutaneously (SubQ) (just under the skin into the fat tissue), most usually around the abdomen region.

The required amount (saturation dose) is 1mcg (microgram) per Kg (Kilogram) of bodyweight. The typical usage and for ease of measuring is 100mcg of mod-GRF(1-29) and/or 100mcg of your choice of GHRP. Lower dosages will simply result in less GH release due to a slightly weaker GH pulse and reduce any side effects you may have. A higher dose will have minimal benefit and is more a waste of money than anything else. But, in saying that, the more frequently dosed in any given day would result in more frequent pulses.

Mixing and reconstituting Bodybuilding Peptides

 

Mixing (reconstitution calculator found here) the lyophilized peptide product in their vials with Bacteriostatic Water (BW) can take some getting used to. The idea is not to add too much dilution. Typical rule of thumb is to add 0.5mL of Bacteriostatic Water to 1mg of Peptide. So a 2mg vial should reconstitute with 1mL Bacteriostatic Water. 5mg with 2.5mL, 10mg with 5mL, etc. Squirt the Bacteriostatic Water along the inside wall of the vial in a smooth controlled manner being cautious not to agitate the mixture too much. It will dissolve itself and become clear. You can roll the vial gently between your fingers or hands but don’t shake it to dissolve. The reconstitute is ok to be drawn once fully dissolved.

On a 1mL needle, there are either 50 tick marks from 0-100, skipping every odd number OR 100 international units (IU). A 100mcg dose is half way between the 2nd and 3rd tick mark, OR 5 IU’s (if you followed the above reconstitution). There are no half tick marks. It is OK to draw mod-GRF and GHRP into the one needle for a single shot. It is NOT OK to mix peptides in the same vial or syringe for storage.

Reconstituted peptides should be stored in the refrigerator to prevent degradation. Left at room temperature, peptide will degrade within days but kept in the fridge will last months. You can pre-load syringes and store in freezer if you want but it is more of a hassle than being worth the effort.

Doses can be taken throughout the day but at no less than 3 hour intervals between doses. 1 dose a day is typical for light injury repair, anti-aging effects, deeper sleep, and better quality of life. The most beneficial would be to dose immediately prior to going to bed for your daily sleep period. Sleep is the time when our pituitary is most active. 2 or 3 doses per day will give the added benefit of lean tissue build, and fat loss, considering your diet consists of good quality foods.

Bodybuilding peptide Doses should be taken on empty stomach to benefit the most. This is usually 3 hours or more.

Do not consume food for between 15-30 minutes after your dosage. Best time is around 20-25 minute mark. GH pulses should peak within about 10 minutes after dosage. Fats and Carbohydrates affect the pulse dramatically. Protein has no effect on pulse and you can have a pure protein source in your stomach at anytime if you so choose to.

Dosage timing can be beneficial to your goals. For muscle growth, the 2nd most beneficial time to dose is post workout (PWO). Best time is pre-bed because sleep is when we recover and our cells repair and grow. Within 30 minutes should be fine but sooner the better. Remember to have your meal 20-25 minutes after dose.

Fat Loss aspects of Peptides

For fat loss, your supplemental dose is 1 hour pre-cardio exercise after a long fasting without food. Best time is after waking up and before breakfast. During cardio exercise, maintain a moderate intensity for between 30-60 minutes. 45 minutes is a good session. You do not want to go too hard or too long. A moderate pace will utilize Free Fatty Acids (FFA) at the highest rate for energy. Refrain from eating for approximately 2 hours after your exercise because this is the time the body is still burning fat as fuel. You must eat throughout the day to reduce the chance of muscle catabolism (breakdown).

These Bodybuilding Peptides can be used on a daily basis for the rest of your life without any harm. Enjoy!!!
