What type of drug is Oxandrolone that was found in the system of  Cinthya Domínguez in 2015?
Oxandrolone Oxandrolone (brand names Oxandrin, Anavar, Lonavar, others), is a synthetic, orally active anabolic-androgenic steroid (AAS) that first became 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.
Methylestradiol Methylestradiol, or 17α-methylestradiol (17α-ME), is a semisynthetic, steroidal estrogen that has been sold in combination with normethandrone (methylestrenolone), an anabolic-androgenic steroid and progestin and, under brand names including Ginecosid, Ginecoside, Mediol, Renodiol for the treatment of menopausal symptoms in Brazil, Venezuela, and Indonesia. Due to the presence of the 17α-methyl group, methylestradiol cannot be deactivated by oxidation of the 17β-hydroxy group, resulting in improved metabolic stability and potency relative to estradiol analogously to ethinylestradiol (17α-ethynylestradiol). In addition to its clinical use, methylestradiol has been studied as a radiopharmaceutical.
