Durabolin - Nandrolone phenpropionate

Nandrolone Nandrolone decanoate (Deca Durabolin) Nandrolone phenpropionate (Durabolin)... 

Anabolic activities of testosterone, such as increases in amino acid incorporation into protein and in RNA polymerase activity, have been demonstrated in skeletal muscle. Apart from the direct anabolic effects in specific tissue, androgens antagonize the protein catabolic action of glucocorticoids. The androgen compounds with the greatest ratio of protein anabolic effects to virilizing effects are the 19-nortestosterone derivatives. Compounds that are used clinically (Table 63.3) include nandrolone phenpropionate (Durabolin), nandrolone decanoate... 

The 17a-alkylated anabolio steroids in olinical use are oxandrolone (Anavar, Oxandrin), oxymetholone (Anadrol-50), stanozolol (Winstrol), nandrolone decanoate (Deoa-Durabolin, Hybolin), and phenpropionate, as shown in Figure 45.10.
