Levothyroxine Sodium (T4)

• Presentación: 100mcg/50tb

• Referencia del proveedor: Thyro4

Thyro 4 by BM is an oral thyroid hormone preparation containing Levothyroxine Sodium (Synthetic T4), engineered to mimic the natural thyroxine produced by the human thyroid gland. It is utilized in advanced athletic and physique-enhancement contexts to artificially upregulate basal metabolic rate (BMR), accelerate caloric expenditure, and support aggressive fat-loss phases.

Active Ingredient & Pharmacology

• Levothyroxine Sodium (T4): A synthetic pro-hormone that converts primarily in peripheral tissues into the active triiodothyronine (T3) hormone, steadily increasing cellular oxygen consumption, thermogenesis, and lipid metabolism.

Administration Protocol

• Initial Dosing: Typically initiated at a very low conservative dose (e.g., 25mcgto 50mcgdaily) to assess individual cardiovascular tolerance and metabolic response.

• Gradual Titration: The dosage is incrementally stepped up by small increments every few days to avoid acute spikes in heart rate or systemic shock.

• Peak Maintenance: Common athletic protocols rarely exceed 100mcgto 200mcgper day, taken strictly as a single morning dose on an empty stomach.

• Tapering & Cessation: Usage requires a gradual downward taper rather than an abrupt stop to allow endogenous thyroid production to recover and prevent rebound lethargy or weight gain.
