T3 100 is a thyroid hormone that is not an anabolic or androgenic steroid. It contains synthetic liothyronine sodium, which is similar to the natural hormone triiodothyronine (L-T3). The thyroid gland of a healthy person normally produces two hormones, L-thyroxine (L-T4) and L-triiodothyronine (L-T3).

T3 is the artificial form of the latter hormone, and it mimics the same effects as if the thyroid gland produced more of it. L-T3 is noticeably more potent and efficient than L-T4, which makes T3 superior to the commercially available L-T4 products such as L-thyroxine or Synthroid. L-T3 has been shown to be 4-5 times more bioactive and to act faster than L-thyroxine (L-T4).

T3 is used in medicine to treat low thyroid function (hypothyroidism), which can cause obesity, metabolic disorders, and fatigue, among other symptoms. Bodybuilders use T3 to boost their metabolism, which leads to a quicker breakdown of carbohydrates, proteins, and fats. Bodybuilders are mainly interested in increasing lipolysis, which means fat burning. Competitive bodybuilders use T3 (Cytomel) in the weeks before a contest to achieve a very low body fat percentage, without having to starve themselves. Athletes who take low doses of T3 report that steroids work better when taken together with T3, probably because of the faster protein synthesis.

Many bodybuilders who appear in “muscle magazines” and have a hard and defined look in photos, eat junk food and compensate by taking T3. The overstimulated thyroid consumes calories like a furnace. Nowadays, instead of T3, athletes use Clenbuterol, which is becoming more popular. Those who combine these two substances will burn a lot of fat. T3 is also popular among female bodybuilders. Since women usually have slower metabolisms than men, it is very hard for them to get in shape for a competition according to today’s standards. A drastic reduction of food and calories below 1000 calories per day can often be avoided by taking T3. Women are more likely to experience side effects than men, but they usually tolerate 50 mcg/day well. A short-term use of T3 in a sensible dose is certainly “healthier” than a severe diet.

The dosage of T3 should be carefully controlled, as T3 is a very powerful and effective thyroid hormone. It is very important to start with a low dose and increase it gradually and evenly over several days. Most athletes start by taking one 25-mcg tablet per day and increase this dose every three to four days by one more tablet. A dose higher than 100 mcg/day is not necessary and not advisable. It is not recommended to take the daily dose all at once, but to split it into three smaller doses to make them more effective. It is also important not to take T3 for more than six weeks. At least two months of rest from the drug should follow. Those who take high doses of T3 for a long time are at risk of developing a chronic thyroid deficiency. As a result, the athlete may have to take thyroid medication for the rest of his life. It is also important to lower the dose slowly and evenly by taking fewer tablets and not to stop abruptly. Those who plan to take T3 should first consult a doctor to make sure that they do not have a thyroid overfunction.

Possible side effects are:

heart palpitation, trembling, irregular heartbeat, heart oppression, agitation, shortness of breath, excretion of sugar through the urine, excessive perspiration, diarrhea, weight loss, psychic disorders, etc., as well as symptoms of hypersensitivity. Our experience is that most symptoms consist of trembling of hands, nausea, headaches, high perspiration, and increased heartbeat.

These negative side effects can often be eliminated by temporarily reducing the daily dosage. Those who use Cytomel over several weeks will experience a decrease in muscle mass. This can be avoided or delayed by simultaneously taking steroids. For the most part, since Cytomel also metabolizes protein, the athlete must eat a diet rich in protein.
