2'H-Androst-2-eno[3,2-c]pyrazol-17-ol,17-methyl-, (5a,17b)-

The systematic name of Stanozolol is (1S,3aS,3bR,5aS,10aS,10bS,12aS)-1,10a,12a-trimethyl-1,2,3,3a,3b,4,5,5a,6,7,10,10a,10b,11,12,12a-hexadecahydrocyclopenta[5,6]naphtho[1,2-f]indazol-1-ol. With the CAS registry number 10418-03-8, it is also named as 17-Methyl-2'H-5alpha-androst-2-eno(3,2-c)pyrazol-17beta-ol. The product's categories are pharmaceutical; active pharmaceutical ingredients; biochemistry; steroids. It is white to light yellow powder which was developed by Winthrop Laboratories in 1962. And it is a synthetic anabolic steroid derived from testosterone, and has been approved by the FDA for human use. But in the United States, like other anabolic steroids, stanozolol is classified as a controlled substance under federal regulation.
