Thioderon, a.k.a. mepitiostane, is a modified version of dihydrotestosterone (DHT). Thioderons possession of a rarely occurring modification causes it to differ from the usual c-17 alpha alkylated group, replacing it with an ether group attached to the 17-beta hydroxyl group (a modification that facilitates oral dosing via the lymphatic system) which serves as an alternate oral delivery method that is not hepatotoxic.

Thioderon is a moderately anabolic, mildly androgenic, non-aromatizing steroid with anti-estrogenic properties. However, due to its limited manufacturing and rarely seen exportation, this steroid is not widely used by athletes.

Steroid Form

This Japan originating steroid comes in capsules containing 5 mg of steroid, and is exclusively manufactured in Japan, where it is available as a prescription medication.

The recommended dosage for Thioderon users is 20-50/day split in halves for twice daily administration (10-25/2x day) for 8-12 weeks, and 20 mg (10 mg/2x day) for 4-6 weeks for female administration, which is often enough to keep blood serum levels well above baseline. Thioderons noticeable improvements in muscle, strength, vascularity, density, and overall bodily definition make it very similar to the legendary cutting steroid Winstrol.

Indications/Purpose & Side Effects

Additional Information

Thioderon, like Winstrol, is extremely versatile and can be added to virtually any stack. Testosterones such as cypionate, propionate, and enanthate should be administered in conjunction with Thioderon to promote proper bodily functions, as well as magnify its anabolic potential. Best suited for cutting purpose, Thioderon is ideally suited for cycles which include Anavar, Sustanon 250, Deca-Durabolin, Trenbolone, Turinabol, Equipoise, and Primobolan.
