Nandrolone is chemically related to the male hormone testosterone. Compared to testosterone, it has enhanced anabolic and reduced androgenic activity. Nandrolone Phenylpropionate serves as a supportive adjunct to specific therapies and dietary measures, as well as parenteral nutrition, due to its faster-acting nature Nandrolone Phenylpropionate is preferred in situations where a more rapid clinical response is required over its chemical variant Nandrolone decanoate. Nandrolone Phenylpropionate is very similar to the popular Nandrolone Decanoate. Nandrolone Phenylopropionate must be injected frequently and at regular intervals, every 2-3 days. The substance nandrolone-phenylpropionate quickly enters the blood, where it remains active for two to three days. The dosage is around 50-150mg per injection, or a total of 150-600mg/week. Nandrolone phenylpropionate has a distinct anabolic effect that aids protein synthesis and allows protein to be stored in the muscle cell in large amounts. This is combined with a moderate androgenic component that stimulates the athlete's regeneration and helps maintain muscle mass during a diet. It shows that Nandrolone Phenylopropionate stores much less water in the body than Nandrolone Decanoate. For this reason, Durabolin is more suitable for a preparation for a competition, while Deca should be given preference for the accumulation of strength and muscle mass. Nandrolone Phenylopropionate, however, can be used for this purpose as well. The gains are smaller and slower than with Deca but of higher quality and remain, for the most part, after discontinuing the compound.This is mainly due to the fact that lower doses are used in most cases, resulting in less HPTA suppression.
