The dosage is usually between 400-600 mg per week (equivalent to 57-86 mg per day). For beginners, it is often only 200-300 mg per week. Doses of more than 600 mg per week are meaningless because not bring appropriate effect and on the other hand increase the risk of side effects. Nandrolone decanoate has a biological half-life of approximately 15 days, and therefore should be taken twice a week to ensure a stable level of intoxication.
