The Phenylpropionate ester is a moderately small or short ester, possessing a half-life far shorter than longer esters such as Enanthate or Cypionate but larger and longer than esters such as Propionate. To give a point of reference, Nandrolone-Decanoate will carry with it a half-life of approximately fifteen days while the Phenylpropionate form of nandrolone will only possess a half-life of approximately 96-120 hours. For this reason, steroids with the Phenylpropionate ester attached will need to be administered more frequently than longer ester based steroids such as Decanoate or Enanthate. Most Durabolin users, as this is the most common Phenylpropionate based steroid will find injections every three days to be the minimal time frame while every 48 hours will prove to be far more efficient.
For bodybuilding beginners dosages of 200mg per week are usual. This is distributed in the first two weeks to 2 injections of 100mg every days. An injection of 200mg per week is then usual.
For advanced bodybuilders dosages of 200 – 600mg per week are usual.
Dosages of 1000 – 1600 mg per week can be found in the professional area. In the dosage range of more than 600mg / week you should consider increasing the dosage of other steroids since the side effects increase with Nandrolone Decanoat at doses over 600mg per week disproportionately.
