Cytomel (liothyronine) is sodium liothyronine (T3). It is available in tablet form in a dose of 25 mcg. It is used to replenish thyroid hormones and also as hormone replacement therapy. The maximum concentration after intake is reached after 4 hours, the elimination half-life is 2.5 days, and up to 95% of the drug is absorbed from the intestine.
Triiodothyronine (T3) is a biologically active form of thyroid hormone. The action of T3 on body tissues is 4 times stronger than that of T4.
Thyrotropin-releasing hormone, a hypothalamic hormone, stimulates the secretion of thyrotropin (TSH), a pituitary hormone, which in turn stimulates the secretion of T4, which is converted by monodeiodinase enzyme into the active form T3, in turn T4 increases the secretion of TTH. In this way, the levels of all hormones are maintained via a negative feedback loop. In addition, TTG increases the activity of the enzyme monodeudinase, which converts T4 to T3.
The thyroid gland works on the principle of negative feedback, accordingly, when exogenous hormones hit, the level of GGT will decrease, which will lead to a decrease in the secretion of T3 and T4.
Unlike AAS, which very quickly suppress testosterone secretion, exogenous thyroxine or triiodothyronine suppress endogenous hormone secretion more slowly. During a short course of 4 to 8 weeks, the TSH may not have time to decrease to 0, as well as the secretion of your own T3 and T4.
The situation is the same with recovery, reduced LH, FSH and testosterone can be recovered for months or even years, while TTG, T3 and T4 are recovered quite quickly, it can take from two to four weeks.
However, there is another nuance, if the recovery of LH and FSH is possible to use anti-estrogens, accelerating the recovery of their own hormones, the drug that increases TSH is not. So in this case we have to wait for a natural recovery of TSH and T3, T4, without any intervention from outside.
Tachycardia. Often a common side effect, especially if the correct dosage of the drug is not observed. This side effect can be managed with beta-adrenoblockers, such as Metaprolol, or others. The dosage is adjusted individually, depending on the situation.
Other side effects such as insomnia, dry mouth, sweating, fever, agitation, and diarrhea are quite rare and usually go away with time or after adjusting the dosage of the drug.

Recommended working doses
The average dosage of the drug is 25 to 75 mcg per day.
There is no post-course therapy as such, but at the same time there is an exit from the course. Withdrawal from the course is a gradual decrease in the doses of the drugs, which is done in the same way as the entry into the course.
