Stanozolol (also known by its brand name Winstrol) is a hard-core steroid, which stays in the system for more than a month if taken orally and up to three months if injected (the injectable form of the drug has been used by veterinarians, but it is no longer commercially available in the . and so is not used routinely now in this country, according to the American Veterinary Medical Association). It first came on the market in 1962 and consists of a four-ring drug structure, which means it is easily spotted in a drug test. Masking agents do not hide its presence.
