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. 
Of concern to any user of Winstrol during a cycle should be its intoxicating effect on the liver . The drug is a 17aa structured steroid , meaning it has been structured in a way which allows it to be orally bio-available, yet this has the negative effect of making Winstrol potentially harmful to the liver. It is therefore paramount the duration of a Winstrol cycle is limited, the dose of the drug is not excessive, the user does not stack it with other hepatotoxic compounds, does not drink alcohol whilst on cycle, and does not use Winstrol if they have an underlying medical condition which effects the livers health. There are supplements available which also help protect the liver (Milk Thistle, Liv-52 etc), and these would be advisable during any Winstrol cycle .
Winstrol is used by bodybuilders especially in cutting cycles. It does raise the amount of testosterone circulating in the body and it does suppress other natural hormones levels, as well as change cholesterol levels. Most doctors limit its use to 6 weeks, although some people have used it for as long as twelve weeks. There are some reports that Winstrol weakens tendons and other reports say it strengthens them and other say it strengthens them unevenly, which could be an issue. Joint stress has also been reported while using Winstrol. It has become popular among women who want to build muscle mass and not gain fat. Anyone not involved in bodybuilding as a sport has alternatives when it comes to eliminating fat and building muscle mass.
