99.9% Stanozolol / Winstrol Pharmaceutical Raw Materials For Mass Muscle CAS 10418-03-8
Stanozolol, sold under the brand names Winstrol and Stromba among others, is a synthetic anabolic - androgenic steroid ( AAS ) which was derived from dihydrotestosterone ( DHT ). It was developed by American pharmaceutical company Winthrop Laboratories ( Sterling Drug ) in 1962, and has been approved by the FDA for human use, though it is no longer marketed in this country.
Unlike most injectable AAS, stanozolol is not esterified and is sold as an aqueous suspension, or in oral tablet form. The drug has a high oral bioavailability, due to a C17α - alkylation which allows the hormone to survive first - pass liver metabolism when ingested. It is because of this that stanozolol is also sold in tablet form.
Stanozolol is one of the AAS commonly used as performance-enhancing drugs and is banned from use in sports competition under the auspices of the International Association of Athletics Federations ( IAAF ) and many other sporting bodies. Additionally, stanozolol has been used in US horse racing.
Stanozolol has been used in both animals and human patients for a number of conditions. In humans, it has been demonstrated to be successful in treating anaemia and hereditary angioedema, the latter of which it has been specifically approved for the treatment of in some countries. Veterinarians may prescribe the drug to improve muscle growth, red blood cell production, increase bone density and stimulate the appetite of debilitated or weakened animals.
In 1980 the FDA removed the dwarfism indication from the label for stanozolol since human growth hormone drugs had come on the market, and mandated that the label for stanozolol and other steroids say: " As adjunctive therapy in senile and postmenopausal osteoporosis. AAS are without value as primary therapy but may be of value as adjunctive therapy. Equal or greater consideration should be given to diet, calcium balance, physiotherapy, and good general health promoting measures. " and gave Sterling a timeline to submit further data for other indications it wanted for the drug. Sterling submitted data to the FDA intended to support the effectiveness of Winstrol for postmenopausal osteoporosis and aplastic anemia in December, 1980 and August 1983 respectively. The FDA's Endocrinologic and Metabolic Drugs Advisory Committee considered the data submitted for osteoporosis in two meetings held 1981 and the data for aplastic anemia in 1983.
