Medically anadrol is approved to treat aplastic anemia. The dosage quoted in the package insert of 1-5mg/kg body weight/day (1-2mg/kg/day typical) is to bring red blood cell count back to normal in the aplastic anemia patient.
At 180lb, that equates to a dosage of 80-400mg/day. However, in a person with normal red blood cell count, the high end of that dosage range will raise blood pressure to dangerously high levels.
