The Oxandrolone hormone does not carry any estrogenic related side effects. It does not aromatize and cannot lead to gynecomastia or water retention due to increases in estrogen levels. It further carries no progestin related activity, which again supports no estrogenic related side effects. Due to water retention being impossible with this steroid, this will decrease the risk of high blood pressure. Excess water retention can promote high blood pressure. Some steroids that do not aromatize can lead to high blood pressure, such as Trenbolone , but Anavar is rarely associated with this trait.
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. 
Although Anavar has been wrongfully touted as being a ‘mild steroid’ in the area of anabolic capability, studies have shown otherwise, and as previously mentioned thus far, it is a compound that is 3 – 6 times the anabolic strength of Testosterone. Therefore, in the athletics and bodybuilding world, Anavar dosages for beginners tend to start and stay in the 25 – 50mg per day range and should provide great results whether bulking up or trimming down the fat. Advanced users tend to venture between 50 – 80mg per day, and there is usually no need to exceed this range due to the dramatic results that such an Anavar dosage can provide. Very rarely, however, experienced advanced Anavar dosages venture within the 80 – 100mg per day range.
