T3, containing Liothyronine Sodium, is an oral synthetic thyroid hormone at 25 mcg/tab in a 50-tab pack from Axiolabs. Known as Tiromel or Cytomel, it's used medically to treat hypothyroidism and off-label in bodybuilding to boost metabolism and fat loss during cutting cycles. It has minimal direct hepatotoxicity but requires careful dosing due to its impact on thyroid function.
T3 increases the metabolic rate by stimulating thyroid hormone receptors, enhancing fat breakdown and energy expenditure. It helps preserve lean muscle while promoting fat loss, contributing to a defined physique. Users notice accelerated fat loss and improved energy within days to weeks, though it may reduce natural thyroid production if misused.
T3 can be safe when used responsibly under professional guidance, but risks include thyroid suppression, heart palpitations, and muscle loss if overdosed. Regular bloodwork to monitor thyroid levels (TSH, T3, T4), heart rate, and lipid profiles is critical. Not recommended for beginners, those with heart conditions, or without medical oversight.
Liothyronine Sodium has a half-life of approximately 2.5 days, requiring daily dosing for consistent effects. It remains detectable in the body for about 1-2 weeks, depending on dosage, metabolism, and testing methods. Bloodwork and professional guidance are advised for precise clearance timelines.
Liothyronine Sodium mimics the natural thyroid hormone T3, binding to thyroid receptors to increase basal metabolic rate, protein catabolism, and fat breakdown. It enhances energy production and fat loss but may suppress natural thyroid output with prolonged use. Its non-anabolic nature means no direct muscle growth, but it supports cutting when paired with proper nutrition. Users notice metabolic boosts within days. What doesn't happen: no significant androgenic effects, but thyroid and cardiovascular monitoring is essential.
T3 excels for bodybuilders in cutting cycles, requiring a controlled calorie deficit, high-protein diet, and training to maximize fat loss while preserving muscle.
Best for experienced bodybuilders seeking fat loss and definition in cutting cycles; suitable for men and women with medical supervision. Not recommended for beginners or those with heart or thyroid issues.

T3 is typically cycled for 4-6 weeks due to its impact on thyroid function. A common protocol starts at 25 mcg/day, increasing by 12.5-25 mcg every 3-5 days to a max of 75-100 mcg/day, then tapers down over 1-2 weeks. Often used in cutting cycles, it's stacked with Clenbutaplex or Oxandroplex for enhanced fat loss. Monitor thyroid levels and taper off to avoid suppression. Bloodwork guides dosing and recovery.
Clenbutaplex: Amplifies fat loss and thermogenesis.
Oxandroplex: Preserves lean muscle during cutting.
Testosterone Propionate: Maintains hormonal balance.
Cycle Support: Supports cardiovascular health during cycles.
T3 vs Clenbuterol: T3 boosts metabolism via thyroid; Clenbuterol is a stimulant with stronger thermogenic effects.
T3 vs T4: T3 is more potent and faster-acting; T4 (Levothyroxine) requires conversion and is milder.
T3 vs DNP: T3 is safer with controlled effects; DNP is extremely potent but risky.
Consult a professional to ensure safe use and monitor thyroid and cardiovascular health.
