Prostanozol, a.k.a. Demethylstanozolol Tetrahydropyranyl, is a modified version of dihydrotestosterone (DHT), an anabolic steroid that was designed as a male testosterone deficiency therapy drug. Prostanozol is structurally identical (with one exception) to Winstrol (Stanozolol) - the well known and definition promoting compound. The only difference between the two is the removal of Winstrols c-17 alpha alkyl (17aa) group - the component that grants it safe liver passage.

Prostanozol replaces the 17aa group with an ether group (attached to the 17-beta hydroxyl group), for which oil solubility, via the lymphatic system, serves as the delivery method.
