Cytomel (liothyronine sodium, triiodtironine, T3)
There are several thyroid hormones which play role in metabolic activity of human organism. They are triiodide-thyronine (L-T3), L-thyroxine (L-T4) and thyrotrophic hormone, which initiates synthesis and activation of thyroxine. Cytomel is a synthetic form levothyroxine sodium which is analogous to triiodide-thyronine.
Cytomel is about 4-5 times more efficient than levothyroxine T4. It has a quicker effect and shortened half-life. In medical practice it is used as a cure for thyroid deficiency (hypothyroidism), fatness, fatigue syndrome etc. Though T3 usage may stop your thyroid functioning for a while – it is safe if you use it properly.
Cytomel may decrease the size of your muscles unless you take anavar, winstrol or primobolan along with it. Clenbuterol may also be helpful. Cytomel T3 is widely used in body-building and fitness as a fat-burner in pre-contest cycles. It can reduce your fat by 5kg in two weeks without exhausting diet or training.
T3 regulates metabolism in cells, so the higher its level the more energy you spend and therefore the more fat you metabolize. Low doses may cause muscle growth, especially when it is accompanied with steroids, probably due to higher protein turnover. Meanwhile high doses may decrease your fat along with muscles. Extreme doses can even destruct your bones.
Cytomel (Liothyronine Sodium) can be used instead of proviron in pre-contest cycles, which is good especially for women. The stack of T3 and clenbuterol may cause tremendous burning of fat due to synergistic effect on beta-2-receptors in adipocytes.
However for bodybuilders taking protein-rich diet is necessary, as well as such steroids like winstrol or primobolan, else you may greatly decrease your muscle mass. You can get optimal results during a short time if you use a combination of Insulin, Cytomel, Primobolan (or Winstrol) and HGH.
Cytomel T3 in bodybuilding and fitness
It’s perfectly suit to burn fat and get a relief in pre-competition cycle. Average effect is burning 5 kgs (11 lbs) within 2 weeks with regular diet and normal workout.
Natural T3 is a regulator of the oxidative metabolism in cell’s mitochondria. Thus higher T3 level means an increase in overall metabolic activity – your body spends more energy and burns more fat because of this. In low dosages, especially if taken along with steroids, it can even serve for certain muscle growth – due to increased metabolism. However, in high dosages it shifts towards catabolism and burns fat along with muscles (too high dosages may even lead to destruction of bones!).
Bodybuilders take advantage of these characteristics and stimulate their metabolism by taking Cytomel (Liothyronine Sodium), which causes a faster conversion of carbohydrates, proteins, and fats. Bodybuilders, of course, are especially interested in an increased lipolysis, which means increased fat burning. Competing body builders, in particular, use Cytomel (Liothyronine Sodium) during the weeks before a championship since it helps to maintain an extremely low fat content, without necessitating a hunger diet. Athletes who use low dosages of Cytomel (Liothyronine Sodium) report that by the simultaneous intake of steroids, the steroids become more effective, most likely as the result of the faster conversion of protein.
Cytomel (Liothyronine Sodium), is a good replacement for proviron on pre-competition cycles, especally for females. The over stimulated thyroid burns calories like a blast furnace. Those who combine T3 and clenbuterol receive synergetic effect especially because of better regulation of beta 2 receptors in fat tissue, which clen tends to deregulate. As a result these two compounds burn an enormous amount of fat.
Proper high-protein diet is important, taking non-bulking steroids like winstrol or primo is desirable while taking T3, otherwise athlete may lose too much muscle, especially while dieting.
A good stack for max results during minimal time might be Insulin, T3, AAS like primo or winstrol and HGH.
As Liothyronine Sodium is rather potent hormone you have to be cautious with dosages. It is necessary to start with low doses and gradually increase them during several days. The usual scheme is 25mcg/day (1 tab) at the beginning gradually increasing it every 3-4 days by 1 tablet. Do not exceed 100mcg/day. The daily dose should be divided into 3 parts and taken separately, which increases its efficiency. If you still take this medication at once, you should do this in the morning.
Men usually take 50mcg, meanwhile for women the dosage should be smaller and it must be individual. Remember that Cytomel at doses 25mcg may cause growth of muscles, which is significant for those women who take it for weight loss only.
Your diet should be rich in proteins if you are not going to lose muscles. The contents of proteins in your food should be 2g per 1kg (2lbs) of your weight. Also workouts are recommended in order to avoid disproportions of your physique.
The period of Cytomel usage should not exceed 6-8 weeks. After that you should refrain from taking it for at least 2 months. If you take high doses for a long period you may develop chronic thyroid insufficiency, and as a result you will have to use this hormone lifelong. Therefore do not exceed the recommended dosages and terms of usage.
One more important thing about this hormone is that one shouldn’t stop using it immediately. The doses should be lowered gradually and smoothly. Before using Cytomel you have to consult your doctor to make sure that you don’t have hyperfunction of thyroid.
If you use Cytomel to improve protein turnover in a mass-gaining cycle, do not exceed 50mcg/day, though 25mcg/day is better for these purposes. For cutting purposes you should take higher dosage. T4 may also do the job (instead of T3), but its dosage differs. The ratio of T4/T3 is approximately 4.5 to 1, i.e. 100mcg of T3 equals 450mcg of T4. However we think that lower dosages of T3 is better.
Usually the dosage of T3 is gradually increased till full dosage within 4-7 days. At the end of a cycle it should be reduced accordingly. However it’s better to prolong the “reduction” period in order to proper restart thyroid, and make it “smoothly”. In other word, you should spend about 5% of your cycle on increase, about 50 % on maximal dosage, and the rest of the time on reduction period.
Here is an example of 3-week cycle (25mcg tablets)
- First four days: 1, 1.5, 2, 3 tablets
- Seven days: 4 tablets
- Ten days: 3, 3, 2, 2, 2, 1, 1, 1, .5, .5 tablets
Note that normally your heart makes about 60-70 beats per minute. If you have the higher rate you should take metapronol (from 25 to 100 mgs/day, do not exceed the dosage).
Cytomel is widely used by women in sports, especially in bodybuilding and fitness. As females have lower rate of metabolism it is hard for them to get into shape. With Cytomel (Liothyronine Sodium) one can avoid exhausting diet with less than 1000 calories a day. Since women are more inclined to side-effects than men, they shouldn’t exceed the dose 50mcg/day. A short-term usage of Cytomel is definitely healthier than extreme dieting.
Liothyronine Sodium Side Effects
Cytomel enhance the growth hormone production, which is not bad actually, however it increases fat and muscle burning. So, the combination of Cytomel and exogenous HGH may cause a synergistic effect, but taking some steroids can be helpful in this case.
Among side effects one should mention: trembling of hands, nausea, headaches, high perspiration, and increased heartbeat. These adverse effects can be solved by temporal reduction of the daily dose.
