Triiodothyronine (T3) is one of the thyroid hormones produced by the thyroid gland. It plays a crucial role in regulating metabolism and energy production in the body. T3 is more biologically active than its counterpart, thyroxine (T4). Both T3 and T4 influence various physiological processes, including heart rate, body temperature, and overall energy levels. Thyroid hormones are essential for maintaining proper growth, development, and overall health.
Thyroid hormones, including T3, play a role in regulating metabolism, and an imbalance can affect weight. An increase in T3 levels can lead to a higher metabolic rate, potentially contributing to weight loss.
Dosage For Fat Loss
Bodybuilders and athletes who wish to use T3 for its weight loss and fat loss effects normally begins with a T3 dosage of 25 – 50mcg per day, and tolerance is assessed. Tolerance relates to the experience of metabolism and fat burning effects, as well as the temperature increase associated with it. Every individual will respond in a different manner and a different intensity to any one given T3 dosage, so it must be understood that a T3 dose of 50mcg for one individual might elicit steady fat loss, but that same 50mcg dose might not do very much for another.
Once tolerance is assessed after remaining at a 50mcg dose for a day or two, the individual should then increase their T3 dosage by an additional 25mcg every day (or every other day, depending on the individual’s experience) until a peak optimal dose is achieved. The typical peak dose for most male bodybuilders and athletes tends to lie in the range of 75 – 100mcg per day. Some have even ventured as high as 125mcg per day, though this is on the high end and is not normally recommended.
Female T3 Dosage
For the most part, the female response to the effects of Cytomel (T3) is the exact same as the male response. The only major difference in Cytomel dosage for females is that of the difference in body weight and mass. Females tend to be of a lower total size, weight, and body mass than men and therefore may tend to be more sensitive to a given T3 dosage.
The peak effective dose for most females should be in the range of approximately 50 – 75mcg per day, with 75mcg being at the uppermost high end
Side effects
Using thyroid hormones, including T3, without proper medical supervision can lead to side effects. Possible side effects may include:
1. *Hyperthyroidism Symptoms:* Excessive T3 intake may cause symptoms such as rapid heart rate, anxiety, tremors, and weight loss.
2. *Heart Issues:* Increased thyroid hormones can strain the cardiovascular system, potentially leading to heart palpitations or irregular heartbeats.
3. *Bone Health:* Long-term use of thyroid hormones in excess may affect bone density, increasing the risk of osteoporosis.
4. *Psychological Effects:* Changes in mood, irritability, and nervousness can occur.
5. *Digestive Issues:* Some people may experience diarrhea or increased bowel movements.
