Some bodybuilders and athletes use trenbolone esters for their muscle-building and otherwise performance-enhancing effects.  Such use is illegal in the United States and many other countries. The DEA classifies trenbolone and its esters as Schedule III controlled substances under the Controlled Substances Act .  Trenbolone is classified as a Schedule 4 drug in Canada  and a class C drug with no penalty for personal use or possession in the United Kingdom .  Use or possession of steroids without a prescription is a crime in Australia .  The infamous "duchess" cocktail allegedly administered to Russian athletes at the Sochi Winter Olympics consisted of oxandrolone , a metenolone ester, and a trenbolone ester. 
The original brand name of oxandrolone was Anavar, which was marketed in the United States and the Netherlands .   This product was eventually discontinued and replaced in the United States with a new product named Oxandrin, which is the sole remaining brand name for oxandrolone in the United States.   Oxandrolone has also been sold under the brand names Antitriol ( Spain ), Anatrophill ( France ), Lipidex ( Brazil ), Lonavar ( Argentina , Australia , Italy ), Protivar, and Vasorome ( Japan ) among others.     Additional brand names exist for products that are manufactured for the steroid black market. 
Testosterone is considered an essential absolute base to any cycle due to the fact that Testosterone is the body’s natural anabolic androgen. It also serves as an all-round excellent mass building compound that is suitable for bulking and strength gaining, and can also be utilized for the purpose of cutting and fat loss as well. In order to carry results further, other bodybuilding steroids are combined with (or “stacked” with) Testosterone. Some of the most popular anabolic steroids in this regard are compounds such as Dianabol (Methandrostenolone) , Winstrol (Stanozolol) , Nandrolone (Deca-Durabolin), and Trenbolone , among a few others. These Dianabol and Winstrol are two examples of oral bodybuilding steroids, though Winstrol does also come in an injectable format that is chemically identical to the oral, and thus even the injectable Winstrol can be ingested orally in order to garner the same effects as the tablet format. Oral anabolic steroids are generally regarded as bodybuilding steroids that are supplementary adjuncts to a solid base anabolic steroid cycle involving injectable bodybuilding steroids (namely, Testosterone).
