Stanozolol is subject to extensive hepatic biotransformation by a variety of enzymatic pathways.

In June 1970 the FDA announced its conclusions on the effectiveness of certain AAS, including stanozolol, based on the NAS/NRC reports made under DESI. The drugs were classified as probably effective as adjunctive therapy in the treatment of senile and postmenopausal ] but only as an adjunct, and in ] (with a specific caveat for dwarfism, "until growth hormone is more available"), and as lacking substantial evidence of effectiveness for several other indications. Specifically, the FDA found a lack of efficacy for stanozolol as "an adjunct to promote body tissue-building processes and to reverse tissue-depleting processes in such conditions as malignant diseases and chronic nonmalignant diseases; debility in elderly patients, and other emaciating diseases; gastrointestinal disorders resulting in alterations of normal metabolism; use during pre-operative and postoperative periods in undernourished patients and poor-risk surgical cases due to traumatism; use in infants, children, and adolescents who do not reach an adequate weight; supportive treatment to help restore or maintain a favorable metabolic balance, as in postsurgical, postinfectious, and convalescent patients; of value in pre- operative patients who have lost tissue from a disease process or who have associated symptoms, such as anorexia; retention and utilization of calcium; surgical applications; gastrointestinal disease, malnourished adults, and chronic illness; pediatric nutritional problems; prostatic carcinoma; and endocrine deficiencies."<ref name=FedReg1970>{{cite journal | title = Food and Drug Administration Notice.DESI 7630.

In 1980 the FDA removed the dwarfism indication from the label for stanozolol since ] 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.
