Nandrolone decanoate is an injectable form of the anabolic steroid nandrolone.The decanoate ester provides a slow release of nandrolone from the site of injection, lasting for up to three weeks. Nandrolone is very similar to testosterone in structure, although it lacks a carbon atom at the 19th position (hence its other name, 19-nortestosterone). Like testosterone, nandrolone exhibits relatively strong anabolic properties. Unlike testosterone, however, its tissue-building activity is accompanied by weak androgenic properties. Much of this has to do with the reduction of nandrolone to a weaker steroid, dihydronandrolone, in the same androgen-responsive target tissues that potentate the action of testosterone (by converting it to DHT). The mild properties of nandrolone decanoate have made it one of the most popular injectable steroids worldwide, highly favored by athletes for its ability to promote significant strength and lean muscle mass gains without strong androgenic or estrogenic side effects.
Nandrolone decanoate is a modified form of nandrolone, where a carboxylic acid ester (decanoic acid) has been attached to the 17-beta hydroxyl group. Esterified steroids are less polar than free steroids, and are absorbed more slowly from the area of injection. Once in the bloodstream, the ester is removed to yield free (active) nandrolone. Esterified steroids are designed to prolong the window of therapeutic effect following administration, allowing for a less frequent injection schedule compared to injections of free (unesterified) steroid. Nandrolone clecanoate provides a sharp spike in nandrolone release 24-48 hours following deep intramuscular injection, which steadily declines to near baseline levels approximately two weeks later. The half-life of nandrolone decanoate is 7-12 days.
For general anabolic effects, early prescribing guidelines recommend a dosage of 50-100 mg every 3-4 weeks for 12 weeks. To treat renal anemia, the prescribing guidelines for nandrolone decanoate recommend a dosage of 100-200 mg per week The usual dosage for physique or performance-enhancing purposes is the range of 200-600 mg per week, taken in cycles 8 to 12 weeks in length. This level is sufficient for most users to notice measurable gains in lean muscle mass and strength. lt is often stated that nandrolone decanoate will exhibit its optimal effect (best gain/side effect ratio) at 2mg per pound of bodyweight/weekly, although individual differences in response will likely dictate varying ideal doses for different users. Deca is not known as a very "fast" builder. The muscle-building effect of this drug is quite noticeable. but not dramatic. ln general, one can expect to gain muscle weight at about half the rate of that with an equal amount of testosterone.
Nandrolone decanoate is often combined with other steroids for an enhanced effect. A combination of 200-400 mg/week of nandrolone decanoate and 10-20 mg daily of Winstrol, for example, is noted to greatly enhance the look of muscularity and definition when dieting/cutting. A strong nornaromatizing androgen like Halotestin or trenbolone could also be used, again providing an enhanced level of hardness and density to the muscle. Being a moderately strong muscle builder, nandrolone can also be incorporated into bulk cycles with acceptable results.The classic"Deca and D-bol" stack (usually 200-400 mg of nandrolone decanoate per week and 15-25 mg of Dianabol per day) has been a bodybuilding basic for decades, and always seems to provide excellent muscle growth. A stronger androgen such as Anadrol 50 or testosterone could also be substituted, producing greater results, but with more water retention.
All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Studies administering 100 mg per week of nandrolone decanoate for 6 weeks have demonstrated an approximate 57% reduction in serum testosterone levels during therapy. At a dosage of 300 mg per week, this reduction reached 70%. lt is believed that the progestational activity of nandrolone notably contributes to the suppression of testosterone synthesis during therapy, which can be marked in spite of a low tendency for estrogen conversion. Without the intervention of testosterone stimulating substances, testosterone levels should return to normal within 2-6 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.
