Liothyronine T3 (Cytonon) 50 mcg

Cytonon T3 (Liothyronine Sodium) 50 mcg is Utinon's synthetic thyroid hormone, supplied as 50 tablets. Liothyronine is the active form of thyroid hormone, so it acts quickly and has a short half-life. Each box is sealed and carries a scratch-off authenticity code inside.

What Cytonon T3 50MCG Is

Liothyronine sodium is the synthetic form of triiodothyronine, the active thyroid hormone. Unlike levothyroxine, it does not need conversion before it can bind the nuclear thyroid receptor. A box holds 50 tablets at 50 mcg, for 2,500 mcg total. The 50 mcg unit is the higher-strength presentation, double the common 25 mcg tablet.

The History of Cytomel T3

Liothyronine was identified as the active thyroid hormone in the 1950s and synthesised for replacement therapy soon after. It was marketed as Cytomel for hypothyroidism and myxoedema. Its rapid onset made it useful in acute settings, while its short half-life made steady dosing more demanding than levothyroxine. It remains a standard comparator for thyroid-hormone research.

How It Works

After absorption, liothyronine enters cells and binds nuclear thyroid receptors, increasing metabolic rate, oxygen consumption and protein turnover. Because it is already the active hormone, the effect begins within hours rather than days. The half-life is roughly one day, so levels fall quickly when dosing stops. Hepatic and renal clearance dominate, and the short half-life means the hypothalamic-pituitary-thyroid axis can recover faster than with levothyroxine.

What the Research Shows

• Liothyronine is the active thyroid hormone and does not require conversion.
• Its metabolic effects begin within hours of administration.
• The short half-life allows faster adjustment than levothyroxine.
• Long-term use can suppress endogenous thyroid output.

Research Context

T3 is the fast end of thyroid-hormone research. Studies comparing it with T4 show that the conversion step in levothyroxine gives the body more control over active hormone levels. That difference is why T4 is the standard replacement and T3 is used when a rapid or direct effect is needed. The 50 mcg tablet is the higher-strength unit and is not interchangeable with 50 mcg of levothyroxine.

Strength, Pack and Authentication

Each tablet contains 50 mcg of liothyronine sodium, and the box holds 50 tablets. The carton is printed and tamper-evident, stating the compound, strength and tablet count. A scratch-off security code inside the box links the pack to Utinon's manufacturing records, and the blister format keeps every tablet protected from moisture and light until it is used.
