Estrogenic Activity High
Progestational Activity High
Norethandrolone is an anabolic steroid closely related to nortestosterone (nandrolone) in structure. The activity of this steroid is that of a mild to moderate oral anabolic steroid, which is accompanied by distinguishable androgenic and estrogenic components. Although this steroid is essentially nandrolone modified (alkylated) to make oral dosing viable, it cannot be looked at simply as an oral alternative to Deca-Durabolin®. Most notably, the greatly increased estrogenicity caused by 17-alkylation makes norethandrolone much more problematic when trying to build quality (lean) muscle mass. In administering an effective amount of steroid in terms of muscle growth, the user has to deal with much more in terms of estrogenic effects. The muscle accumulation with norethandrolone is also going to be accompanied by a high level of water and (likely) fat retention, not the quality side muscularity normally associated with nandrolone decanoate.
