Thyroxyl (T3) 25 mcg

Thyroxyl (T3) – Kalpa Pharmaceuticals Liothyronine Sodium 25 mcg

Thyroxyl (T3) is a pharmaceutical-grade thyroid hormone product manufactured by Kalpa Pharmaceuticals, containing 25 mcg of Liothyronine Sodium per tablet. Bodybuilders and fitness-focused individuals use T3 compounds like Thyroxyl to support fat loss, cutting phases, and metabolic enhancement. Its ability to increase basal metabolic rate makes it a potent non-steroidal aid for reducing body fat while preserving lean muscle.

How Does Thyroxyl (T3) Work?

Liothyronine is the synthetic form of the T3 thyroid hormone, which regulates metabolism and influences how the body uses energy. When administered exogenously, it ramps up the rate at which your body burns calories—even at rest. This makes it especially useful for bodybuilders trying to get shredded during pre-contest prep or extreme fat loss phases.

For a detailed medical overview of T3's mechanism and applications, you can refer to this clinical review from the NIH.

Key Benefits of Thyroxyl (T3) in Bodybuilding

• Significantly increases metabolic rate
• Enhances fat burning and weight loss during cutting cycles
• Preserves muscle when stacked properly with anabolic agents
• Suppresses appetite and boosts energy levels

Due to its powerful thermogenic and catabolic properties, T3 should be carefully dosed and often stacked with protective compounds like Trenboxyl Enanthate or Stanoxyl to prevent muscle breakdown during aggressive cuts.

Dosage and Cycle Guidelines

A typical dosage begins at 25 mcg/day, gradually increasing to 50–75 mcg depending on tolerance. Advanced users may push up to 100 mcg/day in the final weeks of a cutting cycle, but such doses should be tapered off to avoid thyroid shutdown. Cycle length usually ranges from 4 to 8 weeks.

Tapering example: Week 1: 25 mcg → Week 2: 50 mcg → Week 3–6: 75 mcg → Week 7: 50 mcg → Week 8: 25 mcg

Recommended Stacks for Thyroxyl (T3)

For optimal fat-burning while maintaining muscle, stack Thyroxyl with dry and hardening agents such as:

• Clenbutaxyl – a potent beta-2 agonist for synergistic thermogenesis
• Trenboxyl Acetate – to offset catabolic risk of T3
• Anadroxyl – supports muscle fullness during deep cuts
• Letroxyl – useful if stacking with aromatizing agents

Side Effects and Warnings

As a powerful thyroid hormone, misuse of Thyroxyl can result in symptoms of hyperthyroidism such as rapid heart rate, sweating, muscle loss, nervousness, and insomnia. Long-term suppression can affect natural thyroid hormone production. For this reason, cycling off and tapering down is essential. It is not advised for beginners or those with cardiovascular concerns.
