17-methyl steroid

Dextromethorphan is the dextrorotatory enantiomer of levomethorphan , which is the methyl ether of levorphanol , both opioid analgesics . It is named according to IUPAC rules as (+)-3-methoxy-17-methyl-9α,13α,14α- morphinan . As its pure form, dextromethorphan occurs as an odorless, opalescent white powder. It is freely soluble in chloroform and insoluble in water ; the hydrobromide salt is water-soluble up to /100 mL at 25 °C. [31] Dextromethorphan is commonly available as the monohydrated hydrobromide salt, however some newer extended-release formulations contain dextromethorphan bound to an ion-exchange resin based on polystyrene sulfonic acid . Dextromethorphan's specific rotation in water is +° (20 °C, Sodium D-line). [ citation needed ]

Non-medical users of anabolic steroids often “stack” different anabolic steroids over the course of a “cycle” of use. They also administer various ancillary drugs and substances to enhance the desired effects of anabolic steroids or to minimize adverse side effects. The most common liquid (injectable) anabolic steroids encountered in these cases are (oil-based) esters of testosterone (., testosterone cypionate, testosterone enanthate, and testosterone propionate, and a blend of testosterone esters called Sustanon 250) or nandrolone (., nandrolone decanoate). Also popular are Equipoise (boldenone undecylenate) and trenbolone acetate and trenbolone enanthate, as well as the water-based injectable Winstrol (stanozolol). Popular oral anabolic steroids include methandrostenolone (Dianbol), oxandrolone (Anavar) and oxymetholone (Anadrol 50).

  1. Male patients with carcinoma of the breast , or with known or suspected carcinoma of the prostate .
  2. Carcinoma of the breast in females with hypercalcemia ; androgenic anabolic steroids may stimulate osteolytic resorption of bone .
  3. Nephrosis or the nephrotic phase of nephritis .
  4. WINSTROL (anabolic steroids) can cause fetal harm when administered to a pregnant woman.
WINSTROL (anabolic steroids) is contraindicated in women who are or may become pregnant. If this drug is used during pregnancy , or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus .
