oxandrolone Purified 99%

1.Oxandrolone (brand names Oxandrin, Anavar, Lonavar, others), is a synthetic, orally active anabolic-androgenic steroid (AAS) that first become available as a prescription drug in the United States in 1964. It is a 17α-methylated derivative of dihydrotestosterone (DHT) that has an oxygen atom in place of the carbon at the 2 position.

2.Oxandrolone is well-established as a safe treatment for patients recovering from severe burns.Medical research has also established oxandrolone's efficacy in aiding the development of girls with Turner syndrome. Although oxandrolone has long been used to accelerate growth in children with idiopathic short stature, it is unlikely to increase adult height and in some cases may even decrease it. Oxandrolone has therefore largely been replaced by growth hormone for this use.
