T4, also known as Levothyroxine Sodium, is a synthetic thyroid hormone widely used in the bodybuilding and fitness community for fat loss and metabolic enhancement. Dragon Pharma’s pharmaceutical-grade formulation ensures consistent potency, making it a reliable choice for those seeking to regulate thyroid levels or accelerate their cutting cycles.
DRUG DESCRIPTION
Levothyroxine is a synthetic form of thyroxine (T4), one of the primary hormones produced by the thyroid gland. It plays a critical role in regulating metabolism, energy production, and overall cellular activity. In clinical settings, it is prescribed for hypothyroidism, while in performance enhancement, it’s used to boost metabolic rate and support extreme fat loss efforts when thyroid suppression occurs during anabolic steroid cycles.

HOW TO USE T4
T4 is typically taken once daily, preferably in the morning on an empty stomach to enhance absorption. For bodybuilders, it is often used in the 50–100 mcg/day range during cutting cycles or in post-cycle periods where thyroid output may be suppressed. It can be stacked with compounds like MK-677 for enhanced fat oxidation and metabolic support.
Beginners should start at 25 mcg and slowly titrate up every 3–5 days, monitoring for signs of overstimulation such as tremors, palpitations, or anxiety.
POSSIBLE SIDE EFFECTS
Although T4 is generally well-tolerated, excessive doses can mimic symptoms of hyperthyroidism. Users may experience:
- Insomnia
- Rapid heart rate
- Heat intolerance
- Anxiety and irritability
- Muscle loss if not paired with anabolic protection
To minimize risk, it’s essential to taper the dose and avoid abrupt discontinuation.

T4 FAQ
T4 (Levothyroxine) is a prohormone that converts into the more active T3 (Liothyronine) in the body. T3 is faster acting, but T4 provides a steadier release and is generally safer for beginners.
It typically takes 4–6 days for T4 levels to stabilize in the bloodstream. Noticeable metabolic effects may take 1–2 weeks depending on the dose and individual thyroid responsiveness.
Yes, many users stack T4 with compounds like Clenbuterol or Anavar. It’s important to monitor for signs of overstimulation and use liver and heart support when necessary.
Yes, when dosed conservatively. Women often start at 25 mcg/day. It’s important to assess thyroid function and avoid going hyperthyroid. Consultation with a healthcare provider is recommended.
T4 doesn’t suppress testosterone but may suppress endogenous thyroid output. Tapering off slowly helps the thyroid recover naturally. No specific PCT compounds are needed.
