Winstrol is a popular AAS for bodybuilders to build lean muscle and lose fat, but its development is not smooth.
In 1962, Stanozolol was in the United States by Winthrop(Sterling) under the trade name "Winstrol" and in Europe by Winthrop partner Bayer under the trade name "Stromba".
In 1970, the FDA classified Winstrol as potentially effective as an adjunct therapy for elderly and postmenopausal osteoporosis, as well as pituitary dwarfism, and as lacking substantial evidence of effectiveness for several other indications.
The FDA gave Sterling six months to stop marketing Winstrol for indications for which there is no evidence of efficacy and one year to develop further data for two indications for which it may be effective.
In August and September 1970, Sterling submitted additional data; The FDA deemed the data inadequate but allowed the drug to remain on the market because of an unmet need for osteoporosis and pituitary dwarfism, but Sterling needed to produce more data.
1980, the FDA removed the dwarf indication from Winstrol 's label as human growth hormone drugs became available.
In December 1980 and August 1983, Sterling submitted data to the FDA designed to support the effectiveness of Winstrol in postmenopausal osteoporosis and aplastic anemia.
These data review at two meetings of the FDA's Endocrine and Metabolic Drugs Advisory Committee in 1981 and 1983.
In April 1984, the FDA declared the data inadequate.
1988, Eastman Kodak acquire Sterling by for $5.1 billion.
1994 Kodak sold Sterling's drug business to Sanofi for $1.675 billion.
Sanofi, which makes Winstrol in the United States from Searle, discontinued production of the drug in October 2002.
In 2003, Sanofi sold its Winstrol business, along with two other drugs, to Ovation Pharmaceuticals. In the meantime, Winstrol is not discontinue and consider as a treatment for hereditary angioedema.
2009, Lundbeck acquired Ovation.
2010, Lundbeck pulled Winstrol from the U.S. market. No other company has since marketed Winstrol in the United States, but it is available through combination (custom drug formulations).
From the above development of Winstrol , we can see that it went through nearly 50 years before it was withdrawn from the US market in 2010. It is an anabolic steroid that test by market for nearly 50 years. Although it is no longer sell in the United States, it is still available. To this day, Winstrol keep to be the most commonly using AAS by bodybuilders.
