Nandrolone decanoate is an anabolic androgenic and some form 19-nortestosterone A very prominent positive nitrogen balance is realized with administration of this product. Since nandrolone promotes nitrogen storage, growth and repair in hard-trained muscles will be more pronounced than usual. In addition, a noted effect by many athletes polled was that most of them experienced a joint healing effect during Deca cycles.
Dose of common use for men were in the area of 400-600mg per week, and 400 mg weekly dose caused more water retention, while women seemed to do well with 100mgs / week. In fact, women have been reported very respectable lean mass and strength gains only at doses of 50-100mg per week. Virilizing effects usually single weekly injections of 50-100 mg of nandrolone decanoate were avoided.
Men, however would need to stack Deca with testosterone in order to have more appreciable weight gains, and avoid sexual dysfunction. Unfortunately, this compound is detectable for up to a year and a half after the administration, so drug tested athletes should avoid.
