T3 25 mcg by British Dragon is a pharmaceutical-grade oral thyroid hormone containing Liothyronine Sodium (T3), the active form of thyroid hormone responsible for regulating metabolic rate, energy expenditure, and nutrient utilization. In bodybuilding and athletic contexts, T3 is primarily used in advanced cutting phases where precise metabolic control is required.
Unlike stimulant-based fat burners, T3 directly influences thyroid hormone levels, making it significantly more powerful and requiring a disciplined, informed approach. It is not intended for casual or beginner use, but rather for experienced individuals who understand thyroid suppression, tapering protocols, and recovery planning.
Each tablet contains 25 micrograms of Liothyronine Sodium. British Dragon manufactures T3 under controlled pharmaceutical standards to ensure accurate dosing, stability, and predictable physiological response.
Liothyronine Sodium is clinically classified as a synthetic form of triiodothyronine (T3) and is used in medical settings for thyroid hormone replacement. In performance-enhancement environments, it is used off-label for metabolic regulation. Clinical pharmacology of Liothyronine is well documented by the National Library of Medicine (PubMed).
Usage strategies vary significantly depending on experience level, duration, and metabolic response. Conservative introduction and gradual adjustment are essential. Abrupt changes in dosing should be avoided to reduce thyroid stress.
Women should approach T3 with extreme caution. Even low doses can significantly alter thyroid function. Professional supervision is strongly recommended.
T3 has a relatively short active life of approximately 24 hours, which is why it is typically administered daily with careful tapering protocols.
Potential side effects include increased heart rate, sweating, anxiety, fatigue, insomnia, and muscle loss if misused. Long-term or excessive use can suppress natural thyroid function.
Not recommended for beginners or individuals with existing thyroid, cardiovascular, or metabolic disorders. Proper tapering is essential to avoid rebound hypothyroid symptoms.
Overuse may lead to symptoms of hyperthyroidism, including severe cardiovascular strain and nervous system stress. Always prioritize gradual adjustment and conservative use.
T3 is often integrated into advanced cutting protocols alongside compounds such as Clenbuterol for metabolic synergy, or paired with anabolic support like Primobol to help preserve lean mass. Some users also incorporate growth hormone support such as Somatotrobol HGH during longer fat-loss phases.
British Dragon T3 is supplied as 100 oral tablets (25 mcg/tablet), packaged for accuracy, stability, and long-term storage.
Store in a cool, dry place away from light and moisture. Keep the container tightly closed and out of reach of children.
T3 remains one of the most referenced metabolic agents in advanced bodybuilding circles due to its direct thyroid mechanism and predictable effects when used responsibly.
T3 is used to support metabolic rate and fat loss during advanced cutting phases.
No. T3 is a thyroid hormone and does not act through stimulant pathways.
Yes. Improper use can suppress natural thyroid output, which is why tapering is important.
Long-term use is generally discouraged without medical supervision due to thyroid suppression risks.
British Dragon is a long-standing manufacturer known for consistent pharmaceutical-grade products.
