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 side effects. The muscle accumulation with norethandrolone is also going to be accompanied by a high level of water and (likely) fat retentio.n, not the quality muscularity normally associated with nandrolone decanoate.

Norethandrolone was first described in 1954.656 It was developed into a medicine by Searle, which introduced it into the u.S. prescription drug market under the Nilevar brand name during the late 1950's.The drug was originally sold as an oral tablet,an oral solution (with dropper bottle), and an injectable solution (in 25 mg ampules). The latter form of norethandrolone has been out of commerce for so long that few remember it was once also given by injection. Nilevar was prescribed for a variety of illnesses that were benefited by a protein sparing anabolic agent, Listed indications included preparation for and recovery from surgery, severe or prolonged illness, anorexia nervosa, severe burns and trauma, decubitus ulcers, osteoporosis, bone fracture healing, gastrointestinal disease, prolonged corticosteroid administration, and various forms of malnourishment in adults and children.
Norethandrolone ultimately saw only limited success as a prescription anabolic agent. It did make its way to Europe and certain other markets, but not widely.The drug was an early functional anabolic, displaying more tissue-building properties than androgenic effects. But it also remained an agent with a troubling estrogenic side. This eventually lead to norethandrolone being passed over clinically for more refined compounds as they became available. Searle decided to discontinue the sale of Nilevar in the u.S. during the 1960's, and instead began focusing energies on its newer, more strongly anabolic, and non-estrogenic steroid oxandrolone (sold as Anavar). Most other markets carrying norethandrolone, either by Searle or other companies, soon began losing this compound as well. Today, this drug is available on a limited basis, most notably in Australia where it remains viable on the veterinary drug market.

How Supplied:
Norethandrolone is available in select veterinary drug markets. Composition and dosage may vary by country and manufacturer, but typically contain 5 or 10 mg of steroid per tablet.

Structural Characteristics:
Norethandrolone is a modified form of nandrolone. It differs by the addition of an ethyl group at carbon 17-alpha to protect the hormone during oral administration

Administration (General):
Studies have shown that taking an oral anabolic steroid with food may decrease its bioavailability. This is caused by the fat-soluble nature of steroid hormones, which can allow some of the drug to dissolve with undigested dietary fat, reducing its absorption from the gastrointestinal tract. For maximum utilization, this steroid should be taken on an empty stomach.
Administration (Men):
The original prescribing guidelines for Nilevar called for a daily dosage of 20 to 30 mg. This was to be administered on an intermittent basis, with the drug taken for no more than 12 consecutive weeks. Thereafter, a break of at least 1 month was advised before therapy was resumed. When used for physique-or performance-enhancing purposes, the drug is also used intermittently, with cycles usually lasting between 6 and 8 weeks in length followed by 6-8 weeks off. A daily dosage of 20 to 40 mg is most common for such applications. This level is typically sufficient for rapid gains in strength and muscle mass (bulk). The high estrogenicity makes norethandrolone of little value in speed and endurance sports, causing an unwanted retention of water weight. When given by injection, the same milligram dosage is recommended as when the drug is given orally.
Administration (Women):
The original prescribing guidelines for Nilevar made no special dosing recommendations for women, although it did warn that androgenicity is likely on a high dosage. When used by women for physique-or performance-enhancing purposes, a daily dosage of 5-10 mg is most common, taken for no longer than 4 weeks. This level is quite effective for promoting new muscle growth. Note that virilizing side effects are still sometimes noticed at lower doses, and need to be carefully examined for.
