(Mepitiostane)

Thioderon, also known by its chemical name Mepitiostane, is an orally active antiestrogen and anabolic–androgenic steroid (AAS) belonging to the dihydrotestosterone (DHT) group. It is marketed in Japan as an antineoplastic agent, specifically for the treatment of breast cancer. Mepitiostane serves as a prodrug of epitiostanol, meaning it is converted into epitiostanol in the body, where it then exerts its effects. The development and description of this drug trace back to 1968.

This medication has a unique molecular structure that includes a modification from the typical c-17 alpha alkylated group found in similar compounds, replacing it with an ether group attached to the 17-beta hydroxyl group. This modification is designed to facilitate oral dosing via the lymphatic system, enabling effective delivery into the bloodstream when taken by mouth

Steroid Composition

Originating from Japan, this steroid is encapsulated in 5 mg doses, with its production and prescription exclusively managed within Japan.

Dosage Guidelines

The recommended intake for Thioderon ranges between 20 to 50 mg per day, divided into two doses for twice-daily consumption (10-25 mg twice a day) over a period of 8-12 weeks. For females, a dosage of 20 mg per day, split into two 10 mg doses, for 4-6 weeks is typically sufficient to maintain elevated serum levels well above the baseline. Thioderon is noted for its significant effects on muscle enhancement, strength, vascularity, density, and overall physique definition, drawing parallels to the effects seen with the renowned steroid, Winstrol.

Indications, Purpose, and Side Effects

For detailed information on the indications, purpose, and potential side effects of Thioderon, refer to the profile information for Winstrol.

Additional Insights

Thioderon’s flexibility in use is comparable to that of Winstrol, making it a compatible addition to a wide variety of stacks. It is recommended to combine Thioderon with testosterones like cypionate, propionate, and enanthate to support healthy bodily functions and enhance its anabolic effects. Primarily favored for cutting phases, Thioderon works well in cycles that include other steroids such as Anavar, Sustanon 250, Deca-Durabolin, Trenbolone, Turinabol, Equipoise, and Primobolan.
