Levothyroxine is a prescription hormone, not a diet pill. The information below is educational only.

About T4 (Levothyroxine) by Dragon Pharma

Levothyroxine is chemically identical to the thyroxine the thyroid gland produces. On its own it is largely a storage hormone: the body converts it into the active form, T3, in the liver, kidneys, brain and muscles. That is why T4 provides stable, long-lasting levels rather than a sharp peak.

Dragon Pharma supplies T4 as 50 mcg tablets. Each pack contains 100 tablets.

How T4 Works

Mechanism of Action

After absorption, levothyroxine is deiodinated into T3, which binds the nuclear thyroid receptor and sets the metabolic rate of cells. Because conversion and clearance are slow, the elimination half-life is around seven days; in hypothyroidism it stretches to nine or ten days, and in hyperthyroidism it shortens to three or four.

T4 vs T3

T3 (liothyronine) is the already-active hormone, so it acts faster and clears faster. T4 is the opposite: slow, steady and predictable. Most medical replacement therapy uses T4 alone for exactly that stability.

T4 Dosage Guidelines

Dosing

Medical dosing starts low and is titrated by blood work, mainly TSH with free T4. Because it takes about six weeks for daily levothyroxine to reach a steady level, changes are assessed on that timescale, not by how someone feels after a few days. The 50 mcg tablet is a common mid-range strength.

How to Take It

Absorption is easily disturbed: aluminium and magnesium antacids, iron, calcium, sucralfate, soy, fibre and even cow's milk reduce it. The standard instruction is to take levothyroxine in the morning on an empty stomach and wait 30 to 60 minutes before eating or drinking anything except water.

T4 and Cutting Cycles

In bodybuilding, T4 appears in cutting protocols with thermogenics such as Clenbuterol, alongside dry compounds like Anavar or Winstrol, and over a testosterone base. Because T4 depends on conversion, some users combine it with T3; either way, thyroid blood work is what makes the difference between a plan and a guess.

T4 Side Effects and Precautions

Levothyroxine has no meaningful side effects at correct replacement doses; the problems come from too much, which produces hyperthyroid symptoms such as palpitations, sweating, tremor, anxiety and insomnia, plus long-term strain on the heart and bones. Massive overdose needs medical treatment and effects may appear from six hours to eleven days later. T4 is intended for adult use under medical supervision and is not for use by women who are or may become pregnant without medical direction.

Storage Instructions

Store the tablets at room temperature in a dry place, away from direct light and moisture. Keep the pack sealed until use and always store it out of the reach of children.
