Dragon Pharma T4 provides 50 mcg of pharmaceutical-grade Levothyroxine Sodium per tablet — a synthetic form of the T4 thyroid hormone. Known for its role in regulating metabolism, T4 is widely used by bodybuilders and athletes during fat loss cycles to enhance thermogenesis, reduce body fat, and support energy output.
Levothyroxine is a synthetic form of thyroxine (T4), the body's primary circulating thyroid hormone. T4 is a precursor to T3 (triiodothyronine), the more active form, which plays a key role in metabolic rate, oxygen utilization, and nutrient partitioning. According to the National Center for Biotechnology Information, exogenous T4 can treat hypothyroidism and enhance metabolism in non-clinical contexts like physique enhancement.
While slower acting than T3, T4 provides a steadier and more gradual effect on thyroid output, minimizing the risk of crash post-cycle.
Most athletes start at 25–50 mcg daily, potentially increasing to 75–100 mcg based on goals and response. Because T4 converts to T3 in the body, effects compound over several days. A typical T4 cycle lasts 6–8 weeks and is often tapered down to avoid thyroid suppression.
Dragon Pharma T4 is frequently paired with Clenbuterol 40 mcg or Yohimbine 5 mg to intensify fat mobilization. It also works well alongside SLU-PP-332, a PPARδ agonist that further enhances fat oxidation.
For muscle preservation, many users add MK-677 (Ibutamoren) or Testosterone Enanthate during calorie-restricted phases.
T4 should be used carefully to avoid overstimulation or thyroid damage. Common side effects include:
Start low, titrate slowly, and consider monitoring TSH levels for safety.
Dragon Pharma's T4 tablets are manufactured under strict GMP conditions and independently lab-tested for potency. Whether you're cutting for competition or shredding for aesthetics, Dragon Pharma T4 delivers reliable thyroid support to fuel your results.

T4 helps regulate metabolism, energy production, and fat utilization by converting into the active T3 hormone in body tissues.
Yes. T4 increases the metabolic rate, making it easier to burn calories and lose fat, especially when combined with cardio and a calorie deficit.
Absolutely. T4 and Clenbuterol work synergistically to boost thermogenesis and fat loss, commonly used in advanced cutting protocols.
T3 is more active and fast-acting, while T4 is slower but converts into T3 in the body. T4 provides a smoother, longer-lasting metabolic boost.
Yes. Gradually reducing the dose allows your natural thyroid function to recover, minimizing the risk of long-term suppression.
