THYROID T3

T3, or triiodothyronine, is a thyroid hormone responsible for regulating key metabolic functions, including energy production from food and stored substrates like fat, muscle, and glycogen. By stimulating enzymes involved in nutrient uptake and energy burning, T3 significantly increases the rate at which the body processes nutrients. This heightened metabolic activity leads to increased energy demands, meaning additional fuel is required to support the elevated work rate.

Recommended Dosage:

The typical dosage of T3 ranges from 25-100 mcg/day. Since PSL tablets are usually 50 mcg, they can be split in half if a lower dose is needed. There are two main dosing strategies:

1. Low-dose approach (12.5-25 mcg/day): This strategy aims for steady fat loss or maintenance of a balanced body composition. At the lower end, thyroid testing usually shows no detectable suppression, even with extended use. At the higher end, moderate suppression may occur, but results are generally better compared to not using T3. Any suppression seen typically reverses quickly once T3 supplementation is stopped.

2. Higher-dose approach(50-100 mcg/day): Used for more significant fat loss, but comes with the risk of thyroid suppression. This method is often used for short cycles, ranging from 8-12 weeks. Higher doses can lead to side effects such as lean tissue loss and ATP depletion, so a protective agent like anabolic steroids is recommended in such cases.

When used correctly, T3 can greatly enhance fat loss without significant side effects. Careful monitoring and dose management are essential to avoid potential risks.

Benefits of T3 Supplementation:

– Regulates key physiological functions:T3 plays a vital role in metabolism, body temperature regulation, and heart rate.
– Supports metabolism of carbs, fats, and proteins: Ensures proper function of cells and organs.
– Helps in hypothyroidism recovery: T3 supplementation is often used to restore normal metabolic function in individuals with hypothyroidism, alleviating symptoms like weight gain, energy loss, and hair thinning.
– Boosts fat loss for athletes: When combined with a calorie-restricted diet, T3 can accelerate fat loss. However, its use is recommended only with anabolic steroids to mitigate potential muscle loss.

Side Effects of T3 Use:

– Increased metabolic rate: Results in higher energy and oxygen consumption by the body.
– Protein imbalance: While T3 enhances protein synthesis, excessive levels can cause an imbalance between protein breakdown and synthesis, potentially leading to muscle loss.
– Altered glucose metabolism:T3 can enhance glucose breakdown and synthesis, impacting blood sugar levels.
– Cardiovascular effects: T3 increases heart rate and the force of heart contractions, which may raise blood pressure, especially in cases of hyperthyroidism.

precautions and Dosage Recommendations:

– Blood work is essential: Prior to starting T3, have blood tests done to assess your TSH, T4, and T3 levels.
– Limit cycle duration: T3 cycles should not exceed 6 weeks. Any discontinuation should be gradual, reducing the dosage by 15-25 mcg every 3-4 days.
– Avoid abrupt discontinuation:Gradual tapering is necessary to avoid negative effects on thyroid function.
