LIOTHYRONINE SODIUM 50 MCG – 50 TABLETS  Oral T3 Thyroid Hormone

What is Liothyronine Sodium (T3 Cytomel)?

Liothyronine Sodium, widely known as Cytomel, Tiromel, or T3, is a synthetic thyroid hormone compound.¹ Its primary action is to cause a significant increase in the basal metabolic rate (BMR), which results in rapid and effective weight loss. Cytomel is a powerful thyroid agent that is utilized for its fast-acting effects on metabolism.

Mechanism and Key Benefits

• Accelerated Metabolism: Cytomel provides the body with synthetic T3 hormone, directly stimulating metabolic activity across all tissues, leading to efficient fat burning and weight loss.

• Protein Synthesis Boost: This increase in metabolic activity also benefits protein synthesis, which can help support muscle development and preservation, even though fat-burning is the primary goal.

• Energy and Performance: By boosting metabolic functions, Cytomel enhances overall energy levels and indirectly supports the levels of Human Growth Hormone (HGH).

• Fast Results: T3 exhibits a rapid onset of action, often leading to results quickly, making it popular for immediate physique goals (e.g., pre-holiday preparation).

Effective Dosage and Cycling

T3 Cytomel must be dosed with extreme caution due to its direct hormonal effects.

• Recommended Dosage: The typical upper limit is 75 mcg per day.

• Risk of High Doses: Taking more than 75 mcg/day increases the risk of a catabolic effect, which can lead to a decrease in muscle mass and strength. This muscle loss is unlikely if the compound is stacked with anabolic steroids.

• Maximum Duration: It can be taken for up to 9 weeks.

• Common Cycling Style: The most common usage style is a cycling protocol: 3 weeks ON, followed by 3 weeks OFF, and then 3 weeks ON again. This protocol is intended to mitigate the risk of long-term suppression of natural thyroid function.

 Side Effects and Safety Warnings (CRITICAL)

Liothyronine Sodium is a hormone therapy.² Overdosage or misuse can be life-threatening by inducing hyperthyroidism.³

• Hyperthyroidism Risk: Adverse reactions are rare, other than those indicative of hyperthyroidism caused by therapeutic overdosage. Symptoms of overdosage include increased heart rate, palpitations, nervousness, tremors, excessive sweating, and severe weight loss.

• Allergic Reactions: In rare instances, allergic skin reactions have been reported.⁴

• Natural Function Suppression: Prolonged or high-dose use carries the risk of permanently suppressing the body's natural T3/T4 production, leading to dependency.

• Mandatory Consultation: It is crucial to consult a healthcare professional before using T3 Cytomel and adhere strictly to professional medical guidance.

 Frequently Asked Questions (FAQ)

Q1: What is the main difference between T3 (Cytomel) and T4?

T3 (Liothyronine) is the active thyroid hormone that directly affects metabolic rate.⁵ T4 (Levothyroxine) is a pro-hormone that must be converted by the body into T3 before it becomes active.⁶ Cytomel (T3) is faster-acting and more potent than T4.⁷

Q2: Why is the dosage limit of 75 mcg/day so important?

Exceeding 75 mcg per day significantly increases the risk of the body entering a severe hyperthyroid (overactive thyroid) state. This can cause severe cardiovascular strain (rapid heart rate, palpitations) and, crucially for bodybuilders, can trigger catabolism (muscle loss).

Q3: Why is the 3 weeks ON / 3 weeks OFF cycling protocol used?

The cycling protocol (3 weeks ON / 3 weeks OFF) is used to give the body's natural thyroid gland a chance to recover and prevent long-term dependence on the synthetic T3 hormone. Continuous, prolonged use can suppress the natural function of the thyroid gland.

Q4: Does T3 Cytomel suppress natural testosterone production?

No, T3 Cytomel is a thyroid hormone and does not suppress the body's natural testosterone production (HPTA). However, it can amplify the catabolic environment, meaning it is often stacked with anabolic steroids to prevent muscle loss while burning fat.

Q5: Can T3 Cytomel cause hair loss?

While generally rare, a sudden shift into a hyperthyroid state (overdosing T3) can disrupt the hair growth cycle and lead to temporary or increased hair shedding.⁸ This adverse effect is usually related to taking too high a dose too quickly.
