Deca Durabolin belongs to the group of anabolic- androgenic steroids, having an active lifespan of 14-16 days and will be detectable for a timespan of 16-18 months at the most. Deca is optimally used when the steroid cycle is long and lasts in the range of 8-12 weeks. It is usually administered once or twice in a week. 300-600 mg per week is considered a reasonable dosage for men. You can also calculate your appropriate dosage by taking 2 mg of Deca Durabolin for every pound of lean bodyweight you possess. The recommended dosage for women has been set a 50 mg for a week.
