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 the toxicity levels of your liver may not be hugely affected, this does not mean that your liver is completely safe from other things. In fact, your liver will take a hit from using any type of oral steroid because of the fact that when it is consumed in this way, it has to go through your liver which could potentially lead to problems if you take too much Anavar. If you are new to taking steroids, you will notice decent results from taking Anavar pills on their own but most bodybuilders tend to stack it or use it with other steroids to maximise their results.
