The optimal dosage of Deca Durabolin is 200 – 600 mg a week. As stated by many experts in the field of sports pharmacology, the greatest effect brings the dosage at the rate of 4 mg per kilogram of body weight of the athlete in a week. The use of Nandrolone Decanoate at a dose of less than 200 mg usually leads to a very weak anabolic effect, which is greatly enhanced with increasing doses. I must say that the performance from the reception of the soundboard directly proportional to the quantity of its use at the same dosage over 600 mg per week will contribute to the opposite effect, that is, the side effects will be more acute. As stated by many of the “chemists”, beginners is enough 200 mg a week to get the desired result.
