SAZOL (Stanozolol) is a dihydrotestosterone (DHT) based anabolic steroid. Specifically, Stanozolol is a structurally altered form of the DHT hormone, two specific changes to DHT that give us Stanozolol. The first modification is the addition of an attached pyrazol group at the A-ring in place of the 3-keto group. This makes Stanozolol a heterocyclic steroid. The second change is the addition of a methyl group.
