Anavar is an anabolic steroid marketed by Pfizer. Its chemical name is oxandrolone, or oxandrin. Doctors prescribe it to create muscle growth in people who suffer from involuntary weight-loss, such as from HIV and chemotherapy. Because bodybuilders and other athletes have commonly abused Anavar, in the United States it is as an illegal performance enhancer and a Schedule III controlled substance. Don't take Anavar unless a doctor prescribes it. Otherwise, it is illegal and may be dangerous.
Take between 10 and 20 mg of Anavar daily. Your doctor may prescribe a higher dosage in extreme cases, but the side effects are worse at higher doses. Studies show that at a 20 mg daily dose, Anavar has a very minor effect on liver function. At 10 mg, it does not noticeably impact the body's normal testosterone production. Even taking a low dosage, you can gain weight.
Take Anavar at the same time every day. The specific time doesn't matter, but try to be consistent.
Do not exceed 20 mg per day. If you take more than this, your body will start to produce less testosterone. At a dose of 80 mg/day for 12 weeks, Anavar reduces testosterone production by 67%. High dosages of Anavar cause testicular shrinking.
