Winstrol (Stanozolol) is an Anabolic Steroid that was derived from Testosterone in 1962 by Winthrop Labs . The original purpose of this steroid was to help treat people suffering from anemia, it is also often used for veterinary purposes. This high anabolic, low androgenic steroid does not bind to the androgen receptor. For this reason Winstrol is considered a weak steroid in terms of its muscle building properties, it does however cause great increases in strength. Stanozolol is also a popular steroid for females due to its low androgenic properties it makes it a safer choice as side effects such as voice deepening and facial hair are a lower risk when compared to steroids such as Dianabol . This doesn’t mean females should use Winstrol as irreversible masculine side effects are still a risk.
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.
