Product Description:

T3 is a synthetic prescription thyroid hormone, an isomer of the thyroid hormone triiodothyronine (T3). Thyroid hormones stimulate the basal metabolic rate and affect various cellular functions, including the metabolism of proteins, fats, and carbohydrates. T3 is used medically to treat hypothyroidism, a condition where the thyroid is unable to produce sufficient thyroid hormones. Hypothyroidism is diagnosed through blood serum hormone profiles (T3, T4, TSH), with common symptoms including lethargy, sleepiness, weight gain, hair loss, and changes in skin texture. T3 is the most active thyroid hormone in the body and is more potent than T4.

T3 is popular among fitness enthusiasts and athletes for its ability to increase metabolism and accelerate fat breakdown, making it suitable for competition preparation or body sculpting phases. T3 has a fat-reducing effect, but this is based on a context of higher caloric intake with "fat to lose," hence it is often used in conjunction with other weight loss drugs, such as human growth hormone or beta-adrenergic agonists. Some believe thyroid hormones like T3 can enhance the anabolic effects of steroids. Although theoretically, this drug uses proteins and carbohydrates to achieve muscle-building effects, this theory has not been widely proven.

Product History:

In 1891, a thyroid extract containing T3 was first used to treat patients with myxedema (a skin condition associated with hypothyroidism). At that time, drugs containing natural thyroid extracts, effective as much as T3 and T4, had been used clinically for over 60 years. However, in the 1950s, they gradually gave way to newly synthesized thyroid hormone drugs, T3 and T4, whose doses and effects were consistent with those claimed by natural extracts, and more suitable for consumers than animal extracts. While T3 and T4 are widely available in the United States, they only make up a small portion of the steroid market elsewhere. Given T3's effectiveness and rapid action, it is popular among fitness athletes. In the U.S. market, Cytomel is the most recognized brand name, produced and sold by King Pharmaceuticals.

Specifications Provided:

Oral tablets available in 5 mcg, 25 mcg, and 50 mcg dosages.

Structural Characteristics:

T3 is a synthetic form of the T3 thyroid hormone, chemically named L-tyrosine, O-(4-hydroxy-3-iodophenyl)-3,5-diiodo, sodium salt.

Warnings:

The U.S. Food and Drug Administration requires that T3 prescription medications sold in the U.S. must be labeled with a black box warning stating, "This product contains thyroid hormone, which can be used alone or in conjunction with other medications to treat obesity. T3 is ineffective for weight loss in patients with normal thyroid function. High doses may produce life-threatening side effects, especially those involving the sympathetic nervous system, such as appetite suppression."

Side Effects:

Excessive use can lead to side effects, including headaches, irritability, nervousness, sweating, irregular heartbeat, increased bowel motility, or menstrual irregularities. It may even cause shock and can exacerbate or trigger angina and heart failure. Long-term excessive use of T3 can lead to hyperthyroidism or an excess of thyroid hormones in the body. Additionally, abruptly reducing or stopping the use of this medication can also cause side effects. Acute or massive usage can be life-threatening.

Therapeutic Guidance:

For treating mild hypothyroidism, the typical starting dose is 25 micrograms per day, increasing by no more than 25 micrograms every one to two weeks. The maintenance dose usually ranges from 25-75 micrograms/day, taken once a day in a single dose. Although T3 is fast-acting, its effects may continue for several days after cessation.

Fitness enthusiasts and athletes looking to accelerate fat loss may start with a daily dose of 25 micrograms, then increase by an additional 25 micrograms every 4-7 days, up to a maximum of 75 micrograms per day. The slow increase in dosage helps the body adjust to the elevated thyroid hormone levels and avoid side effects due to sudden changes.

The T3 cycle should not exceed 6 weeks, and the medication should not be abruptly discontinued. Similarly, if stopping the medication, it should be reduced by 25 micrograms every 4-7 days. This gradual reduction allows the body time to adjust its endogenous hormone secretion levels at the end of the treatment period to avoid side effects.
