Dosage and method of application of T4-Liothyronine sodium

When used to burn fat, bodybuilders mostly use the compound during drying cycles when they want to get lean and shredded. Reports of athletes, as a rule, suggest that the maximum dose of 200-400 mcg per day should be used in order to be useful and avoid side effects.

Most often, buyers suggest starting the dosage with a dosage of 100 mcg per day, and then it should be slowly increased every 1-2 days by approximately 25 mcg or 50 mcg until the maximum daily dose is reached.

At the end of the cycle, the user should slowly reduce the dosage and not stop it abruptly. The dosage should be reduced by approximately 25 or 50 mcg per day every 2-3 days until the dosage reaches zero.

It is very important to slowly increase and slowly decrease so that the thyroid gland adapts accordingly. The duration of the T4 cycle is usually 4-6 weeks with an absolute maximum of 8 weeks.

Side effects

The most common side effects attributed to T4 are insomnia, tremors, restlessness, irregular heartbeat, and suppression of the natural reproduction of thyroid hormones.
