<p>Nandrolone Decanoate is an injectable anabolic preparation. The pharmacologically active substance is nandrolone. The decanoate ester gives the preparation duration of action of about three weeks after injection. Nandrolone Decanoate is chemically related to the male hormone. Compared to testosterone, it has an enhanced anabolic and a reduced androgenic activity. This has been demonstrated in animal bioassays and explained by receptor binding studies. The low androgenicity of nandrolone Decanoate is confirmed in clinical use.<br />

In the human, Nandrolone has been shown to positively influence calcium metabolism and to increase bone mass in osteoporosis. In women with disseminated mammary carcinoma Nandrolone Decanoate has been reported to produce objective regressions for many months. Furthermore, Nandrolone Decanoate has a nitrogen-saving action. This effect on protein metabolism has been established by metabolic studies and is utilized therapeutically in conditions where a protein deficiency exists such as during chronic debilitating diseases and after major surgery and severe trauma. In these conditions, Nandrolone Decanoate serves as a supportive adjunct to specific therapies and dietary measures as well as parenteral nutrition.<br />

Androgenic effects (e.g. virilisation) are relatively uncommon at the recommended dosages. Nandrolone Decanoate lacks the C 17 alpha-alkyl group which is associated with the occurrence of liver dysfunction and cholestasis.</p>
