Cytomel: pros and cons

Cytomel: pros and cons

What is Cytomel?

Cytomel is usually associated with the brand name of the synthetic thyroid hormone Lyotironin sodium. The drug is an excellent copy of the naturally-produced thyroid hormone triiodothyronine or, as it is commonly called, the hormone T3. While synthetic Cytomel has been available since the 1950s, thyroid hormones, including T3, have been used in medicine since the 1890s.

Early thyroid treatment plans included biological extracts from animals that contained pure forms of the T3 and T4 hormones. The extracted thyroid hormones have been very useful for therapeutic purposes, especially for the treatment of hypothyroidism.

Hypothyroidism is a condition in which the thyroid gland does not produce enough hormones, which can lead to weight gain, loss of energy, hair loss, as well as changes in the appearance and texture of the skin. The intake of Cytomel, a synthetic model of the hormone T3, turned out to be safer and healthier for such treatment.

Cytomel Pros and cons

Cytomel is not the only available synthetic thyroid hormone. Hormone T4, sodium levothyroxine, is most available under the brand name Synthroid. T3 and T4 are similar in nature; however, it is believed that T3 is 4-5 times stronger than T4. Simply put, T4 acts as a backup of T3, which makes Cytomel the more powerful of the two popular thyroid hormones. Although these two hormones are popular in the treatment of hypothyroidism, athletes prefer Cytomel to increase productivity. Consumers of anabolic steroids usually take Cytomel in an attempt to lose weight.

Functions and properties of Cytomel

Citomel or T3 is a thyroid hormone that significantly affects the metabolic rate, stimulating it. This hormone is involved in many cellular functions, including the metabolism of carbohydrates, fats and proteins. If this hormone is not sufficiently produced in the human body, as, for example, with hypothyroidism, the metabolism will not function properly. With hypothyroidism, body fat will increase, which is extremely difficult to fight. There may also be a loss of energy, and in some cases, hair loss. Reception of Cytomel provides the body with the thyroid hormone necessary to solve this problem.

Typically, low doses of Cytomel are used to treat hypothyroidism. This will not necessarily contribute to weight loss, but should return the metabolism to proper functioning. However, many athletes prefer to take Cytomel in order to increase fat loss. Taking Cytomel , along with a diet that restricts calorie intake, will contribute to a significant and accelerated burning of fat. Due to its effectiveness, this type of application is recommended without taking anabolic steroids. This is one of the most powerful tools for weight loss that we have at our disposal, but it cannot be called ideal.

Functions and properties of Cytomel

Many athletes who speak out complain that the Cytomel makes them lethargic, which is not surprising. Cytomel feeds on ATP. The need to take high doses to achieve maximum results in weight loss, as well as ATP depletion, can lead to loss of muscle tissue. The body will take everything necessary from any sources in order to satisfy its energy needs. For this reason, it is recommended to take Cytomel in combination with an anabolic remedy.

Cytomel action

The action of Cytomel is usually the same, regardless of the purpose of use: treatment of hypothyroidism and increased fat loss for performance purposes. In both cases, hormonal functions are the same as direct copies of the hormone T3. Regardless of the initial reason for admission, fat loss will occur. With hypothyroidism, patients will improve metabolism, which contributes to weight loss. This is often welcomed, since during the period of thyroid dysfunction, a significant increase in weight is observed. In order to increase productivity, this effect is also welcomed, as it accelerates the process of fat loss.

Regardless of the specific reasons for taking Cytomel, which, although it increases metabolism, you should still follow a diet. In order to lose weight, you need to burn more calories than you eat. If you consume more calories than you burn, then Cytomel will not help you. However, in order to increase productivity, a person who is already producing the right amount of T3 can take a little more calories than usual and still lose weight. When taking Cytomel, the rate of burning calories is enhanced due to an excess of the hormone T3.

Combinations with other drugs

Some have also found that taking Cytomel may have advantages in combination with Growth Hormone (GH), especially when taking high doses of GH. Some data have shown that large amounts of GH can reduce the natural production of T3. Such an addition to taking Tsitomel cannot be called necessary, but he has certain reasons. Despite this, taking Cytomel and GR, no doubt, weight loss will occur at a more accelerated pace. This will be due to the incredible properties of GR to increase metabolism. And if you additionally take a beta-2 stimulant, such as Clenbuterol, a person will turn into a fat burning machine.

The last action of Cytomel is anabolic in nature. Some suggest that Cytomel has the benefits of anabolic by increasing the anabolic effects of anabolic steroids. The idea is that anabolic steroids provide a large coefficient of utilization of carbohydrates, fats and proteins, and Cytomel, as already mentioned, promotes the metabolism of these beneficial substances. At the same time, in theory this will help strengthen the whole body. However, although this theory exists and is supported by the fact that some athletes have improved performance, it lacks credibility. Most can only rely on the use of Cytomel for its intended purpose.

Side effects of Cytomel

Cytomel is generally considered a well-tolerated hormone for most healthy adults, except for patients with hypothyroidism. Side effects of Cytomel usually occur due to an overdose of the drug or taking too high doses, individual sensitivity to the drug should also be considered. Possible side effects of Cytomel include:

  • Headache
  • Sweating
  • Arrhythmia
  • Nervousness
  • Intestinal motility
  • Menstrual irregularities

Extremely high doses or excessive exposure to the T3 hormone can also lead to possible complications. Side effects of Cytomel in this category include:

  • Sore throat
  • Shock
  • Chronic heart failure
  • Hyperthyroidism

Generally speaking, Cytomel is a very safe drug for the thyroid gland, but abuse of especially high doses for a long time can be life threatening.

The final side effect of Cytomel that needs to be discussed is hypothyroidism. Many are afraid to take this drug, due to the possibility of a condition of hypothyroidism, after taking the drug. This fear is that as soon as the drug is finished, the body will stop producing its own T3, which will cause weight gain again. The drug can be addictive, but if used correctly, this is unlikely. Proper use applies not only to the dosage and duration of administration, but to the specific how to properly stop taking the drug. It is impossible to stop the reception sharply. Instead, in a short period of time, you need to lower the dose to the maintenance dose to allow the thyroid gland to restart.

Side effects of Cytomel

Cytomel for weight loss

Many women and bodybuilders resort to the use of thyroxine as a means for losing weight. Thyroxine has a powerful fat burning effect, increases calorie consumption and accelerates metabolism. Its popularity has declined recently due to a negative effect on the heart, thyroxine has an adrenaline-like effect, causing the heart to beat more often, and at the same time it causes a feeling of excitement and anxiety, which are not very well tolerated. "Caution" However, many side effects can be eliminated by combining thyroxine and beta-blockers. Beta-blockers inhibit the receptors through which thyroxin acts on the heart, so they prevent the negative effects of thyroxin on the heart, normalize the rhythm and reduce the manifestation of some other side effects of thyroxin.

Many believe that thyroxin can irreversibly suppress the function of its own thyroid gland, however, studies have shown that even large doses of the drug after 3 weeks of intake reduce their own hormone secretion by only 20%, while after 4 weeks the secretion returned to normal.

Advantages of thyroxine: high availability and effectiveness. Thyroxine disadvantages: a fairly large number of side effects, however, many of them can be prevented.

Exogenous thyroxine can cause artifact thyrotoxicosis. In this case, in contrast to the true thyroid hyperfunction, the level of thyroglobulin (TG) will be lowered.

How to take: a course for weight loss

  • Start taking thyroxine with 50 mcg per day, 2 times a day (25 mcg) in the first half of the day. In the morning, take 25 mg of metoprolol (a beta-blocker that eliminates heart congestion and heartbeat) if the heart rate after lunch is above 70 beats. per minute at rest, then take another 25 mg of metoprolol.
  • Gradually increase the dose to 150-300 mcg per day, 3 times a day until 18:00. Increase the daily dose of metoprolol to 100 mg (50 mg 2 times a day). The dosage of metoprolol is selected individually, so that the resting pulse rate is 60-70 beats. per minute.
  • Reduce thyroxine if severe side effects occur.
  • Watch your heart rate, if at rest the heart rate is above 80 - increase the dose of metoprolol by 25 mg, if the pulse at rest is below 60 beats per minute, reduce the dose of metoprolol by 25 mg.
  • Watch your blood pressure, it should not be higher than 140/90 mm RT. Art. Metoprolol lowers blood pressure.
  • The course lasts 4-7 weeks.
  • Do not stop taking thyroxine abruptly: start reducing the dose 2 weeks before the end of the cycle, continue a gradual decrease until it is completely canceled.
  • If you have diarrhea, include 1-2 capsules per day in the course of loperamide.
  • The minimum break after the end of the course is 3-4 weeks.

If there is a severity in the heart area, it is better to add Asparkam in addition to Metoprolol. 4-6 tablets per day, divided into 2-3 doses, after meals. Also, it will not be out of place to improve the work of the heart with Riboxin. 2-4 tablets at a time, 2-3 times a day. Riboxin will improve the energy balance of the myocardium, and Asparkam will become the source of Potassium and Magnesium necessary to maintain a normal heart rhythm.

Cytomel Reviews

With hypothyroidism, although it is not as common in the Canada as T4, it is the most effective and guaranteed way to treat this condition. Taking T4, to get the effect, you need to wait a while until the hormone is converted to T3, Cytomel fixes the problem from the very beginning. The same can be said of weight loss. T4 can also be a good tool for losing weight, but it’s also close not like T3.

Speaking athletes, who represent the majority of Cytomel consumers, fear this hormone. However, most fears are groundless, based on years of Internet myths. Yes, admission can lead to hypothyroidism, but proper admission will avoid this. In fact, there is very little evidence that confirms these fears when taking Cytomel. Although we have provided the safest guide for taking Cytomel , most of the data prove the ability to take Cytomel for a long period of time, without any damage.

You can take Cytomel for most of the year, not the whole year, and not for everyone, but you can. This is possible, more than possible, while maintaining the proper functioning of the thyroid gland, until the time of stopping the intake to give the body time to return to normal. There are only a few drugs that are superior in power to Cytomel for weight loss.
