Deca-Durabolin® is the Organon brand name for the injectable steroid nandrolone decanoate. Thís compound came around early in the wave of commercial steroid development, first being made available as a prescription medication in 1962. This steroid is an extremely long acting compound, with the decanoate ester said to provide this drug a slow release time of up to three or four weeks. While perhaps true in a technical sense, what we find with further investigation is that the release parameters after a single injection are such that a strong release of nandrolone is really only maintained for one to two weeks. This figure admittedly fails to take into account drug buildup that may occur after multiple injections, which may allow a longer duration of good effect to be seen. Figure 1 is provided to illustrate the release dynamics of a single 200mg injection. As you will see, by the end of the second week levels are already approaching baseline.

World Wide “Deca” is one of the most widely used anabolic steroids. Its popularity is due to the simple fact that it exhibits many very favorable properties. Structurally nandrolone is very similar to testosterone, although it lacks a carbon atom at the 19th position (hence its other name 19-nortestosterone). The resulting structure is a steroid that exhibits much weaker androgenic properties than testosterone. Of primary interest is the fact that nandrolone will not break down to a more potent metabolite in androgen target tissues67. You may remember this is a significant problem with testosterone. Although nandrolone does undergo reduction via the same (5-alpha reductase) enzyme that produces DHT from testosterone, the result in this case is dihydronandrolone. This metabolite is weaker than the parent nandrolone68, and is far less likely to cause unwanted androgenic side effects. Strong occurrences of oily skin, acne, body/facial hair growth and hair loss occur very rarely. It is however possible for androgenic activity to become apparent with this as any steroid, but with nandrolone higher than normal doses are usually responsible.

Nandrolone also show an extremely lower tendency for estrogen conversion. For comparison, the rato has been estimated to be only about 20% of that seen with testosterone69. This is because while the liver can convert nandrolone to estradiol, in other more active sites of steroid aromatization such as adipose tissue nandrolone is far less open to this process70. Consequently estrogen related side effects are a much lower concern with this drug. An antiestrogen is likewise rarely needed with Deca, gynecomastia only a worry among sensitive individuals. At the same time water retention is not a usual concern. This effect can occur however, but is most often related to higher dosages. The addition of Proviron and/or Nolvadex® should prove sufficient enough to significantly reduce any occurrence. Clearly Deca is a very sale choice among steroids. Actually, many consider it to be the best overall steroid for a man to use when weighing the sido effects and results. It should also be noted that in HIV studies, Deca has been shown not only to be effective at safely bringing up the lean body weight of patient, but also to be beneficial to the immune system.

It is of note however that nandrolone is believed to have some activity as a progestin in the body”. Although progesterona is a c-19 steroid, removal of this group as in 19-norprogesterone creates a hormone with greater binding affinity for its corresponding receptor. Sharing this trait, many 19-nor anabolic steroids are shown to have some affinity for the progesterone receptor as well72. This can lead to some progestin-like activity in the body, and may intensify related side effects. The side effects associated with progesterone are actually quite similar to those of estrogen, including negative feedback inhibition of testosterone production, enhanced rato of fat storage and possibly gynecomastia. Many believe the progestin activity of Deca notably contributes to suppression of testosterone synthesis, which can be marked despite a low tendency for estrogen conversion73.

Deca is not known as a very “fast” builder. The muscle building effect of this drug is quite noticeable, but not dramatic. The slow onset and mild properties of this steroid therefore make it more suited for cycles with a longer duration. In general one can expect to gain muscle weight at about half the rato of that with an equal amount of testosterone. A cycle lasting eight to twelve weeks seems to make the most sense, expecting to elicit a slow, even gain of quality mass. Although active in the body for much longer, Deca is usually injected once per week. The dosage for man is usually in the range of 200-600mg. If looking to be specific, it is believed that Deca will exhibit its optimal effect (best gain/side effect ratio) at around 2rng per pound of bodyweight/weekly. Deca is also a popular steroid among female bodybuilders. They take a much lower dosage on average than man of course, usually around 50mg weekly. Although only slightly androgenic, women are occasionally confronted with virilization symptoms when taking this compound. Should this become a concern, the shorter acting nandrolone Durabolin® would be a safer option. This drug stays active for only a few days, greatly reducing the impact of androgenic buildup if withdrawal were indicated.

As mentioned earlier, endogenous testosterone levels can be a concern with Deca-Durabolin, especially after long cycles. It is therefore a good idea to incorporate ancillary drugs at the conclusion of therapy. An estrogen antagonist such as Clomid® or Nolvadex® is therefore commonly used for a few weeks. These both provide a good level of testosterone stimulation, although they may take a couple of weeks to show the best effect. HCG injections could be added for extra reassurance, acting to rapidiy restore the normal ability of the testes to respond to the resumed release of gonadotropins. For this purpose one could administer three injections of 2500-5000 I.U., spaced five days apart. After which point the antiestrogen is continuad alone for a few more weeks in an effort to stabilize the production of testosterone. Remember to begin the ancillaries after Deca has been withdrawn for a few weeks, not the first week after the last shot. Deca stays active for quite some time so the ancillary drugs will not be able to exhibit their optimal effect when the steroid is still being released into the bloodstream.

The major drawback for competitive purposes is that in many cases nandrolone metabolites will be detectable in a drug screen for up to a year (or more) after use. This is clearly due to the form of administration. As discussed

Earlier in this book, esterified compounds have a high affinity to stay stored in fatty tissues. While we can accurately estimate the time frame it will take for a given dose to enter circulation from an injection site, we cannot know for sure that 100% of the steroid will have been metabolized at any given point. Small amounts may indeed be stubbom in leaving fatty tissue, particularly after heavy, longer-term use. Some quantity of nandroloñe decanoate may therefore be left to sporadically enter into the blood stream many months after use. This process may be further aggravated when dieting for a show, a time when body fat sores are being actively depleted (possíbly freeing more steroid). This has no doubt been the cause for many unexpected positives on a drug screen. The fact that nandrolone has been isolated as the “hands-off” injectable for the drug tested athlete is most likely due to its popularity (and therefore common appearance on drug screens). The same risk would of course hold true for other long chain esterified injectables such as Equipoise®, Parabolan and Primobolan®.

On the other hand we find that the use of the oral nandrolone precursors norandrostenedione and norandrostenediol can allow the drug-tested athlete the benefit of an injectable nandrolone, without the same risk for a positive result. A recently published French study makes this possibility very clear. During this investigation it was shown that trace levels of the nandrolone metabolites norandrosterone and noretiocholanolone could be found in human urine up to eight months after a single 50mg injection of nandrolone undecanoate”. This time frame shrank to only 8 days with norandrostenediol (50mg) and norandrostenedione (100mg). I have also had the opportuníty to speak with an amateur bodybuilder recently, who was unexpectedly subject to a drug screen and now strongly supports the use of oral precursor hormones. He was using up to 3 grams norandrostenedione daily not very far from the date of the show, and to his amazement did not test positive for steroid use.

Those not subject to a drug screen are likely to find the low water retention and good effect of this drug favorable for use in pre-contest cutting stacks. A combination of Deca and Wínstrol® during the weeks/months leading up to a show for example, is noted to greatly enhance to look of muscularity and definition. A strong non-aromatizing androgen like Halotestin® or trenbolone could be further added, providing an enhanced leve! of hardness and density to the muscles. Being an acceptable anabolic, Deca can also be incorporated into bulk cycles with good results. The classic Deca and Dianabol cycle has been a 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 resuits. When mixed with Deca, the androgen dosage can be kept lower than if used alone, hopefully making the cycle more comfortable. Additionally one may choose to continue Deca for a number of few weeks after the androgen has been stopped. This will hopefully harden up some of the bloat produced by the androgen, giving a more quality appearance. Remember that endogenous testosterone production will not resume during Deca therapy, and ancillaries are likewise still needed.

On the black market Deca remains one of the most popular anabolics in circulation. Currently 200mg/ml preparations from Mexico are dominating the marketplace, and due to their high availability and lower cost are minimizing the appearance of lower dosed compounds. For example, in addition to Norandren 200 Brovel also makes Norandren 50 (a 50 mg/ml version of this steroid), but it is almost unseen right now. I should point out that their 50ml vial of Norandren 200 is also the largest container of nandrolone to be found in such strength, and represents one of the best values anywhere for this steroid. We can see why it is much more desired right now. Also common are Nandrolona 200 from Tornel and Decanandrolen from Denkall, both in 10ml vials. In an effort to provide more innovative, conspicuous and cost-effective products, the Mexican firm Ttokkyo has recently topped its competitors and released Nandrolona 300. This is a 300mg/ml preparation of nandrolone decanoate, which is by far the highest dose of this compound ever to be produced commercially. To spite the defiant opinions of many, indeed this is a legitimate product. I have not experimented with the solubility of nandrolone decanoate myself, but do know that this particular ester is highly fat-soluble. Reaching 300mg in a milliliter of oil does not seem like an unreasonable or impossible task, and I would guess requires at best some minor tweaking of alcohol levels (perhaps none at all).


Deca is still one of the most widely duplicated drugs in the world, with fakes taking on many different forms. Since it is marketed in so many countries throughout the world, it will no doubt always be a tricky buy. I will start by running down some of the more popular items currently found on the U.S. black market.

From Mexico the most sought after and trusted products currently include Ttokkyo’s Nandrolona 300, Denkall’s Decanandrolen, the Tornel product Nandrolona 200 and Brovel’s Norandren 200. All of these items except the Tornel product are protected from counterfeiters with hologram stickers, so make sure to look for them when shopping. No counterfeits of any of these products are actually known to exist though, making them all very reliable purchases whenever located. At this point in time if you were looking for a worry free product, I would shop for them exclusively. The Organon redi-jects from Mexico are also still equally safe buys, but in light of the abundant market for higher dosed nandrolone products are becoming less and less conspicuous in the U.S. They are simply much too expensive and bulky to bother importing when so many other better products are available.

Copies of the Greek Extraboline may still be circulating, and can be identified by an overlapping label placed on the vial and noticing that the box is devoid of the proper Greek Drug ID sticker.

The old counterfeit U.S. Steris product in green boxes with gold print may still be circulating the black market as well. The label peels right off the bottle, which is an immediate indicator.

The Deca-Pronabol amps from India, three 200mg/2ml amps to a tray, is a safe buy, but unfortunately not as popular here as we would like. Infar Deca (100mg) from India has also been seen as of late and is a legitimate product.

The Norma Hellas vials from Greece (generic), packaged in a small blue box containing a single 2ml vial of 200mg, have become more and more troublesome the past couple of years. Fakes are circulating in high volume at this time, making Normas a more risky purchase. One fake can be identified by its slightly larger label size and smooth expiration date printing, although others have been found recently as well. I left the original real and fake comparison from Anabolics 2000, but again, it does not protect against all of the fakes currently found. The best advice is to make sure you purchase these only when found in boxes bearing a legitimate Greek drug I.D. sticker.

Retabolil, “Russia Deca”, is another legitimate brand (25mg/50mg) being found in the States. These amps are found with 2 distinct labeling styles, silk-screened red/yellow ink and a simple paper label with black print. They also have no band around the neck and no scoring on the glass. The larger box comes with a file, which is required to open this ampule. These ampules have been made with 2 labeling styles, the first being a very easy to rub off red and yellow silk-screen directly on the glass and the other being the simple paper label with gray text. Both versions are legit, although another resource incorrectly lists the paper labeled amp as fake.

IP Deca has gained a strong following despite being a counterfeit product; as for years it was one of the only 200mg/ml Deca available to athletes in any quantity on the black market. These products still circulate today, and are still trusted by athletes.

Aside from some of the discontinued U.S. products, the Mexican veterinary generics and the Norma Hellas product from Greece, you should not come across any legitimate ampule/vial bearing only the generic label “nandrolone decanoate”. There are piles of fake ampules in circulation that bear just the generic name. Trust none of these! Purchasing only products that bear some form of a brand name is an excellent rule to live buy.

Aside from the new 200mg Brovel Norandren, 200mg Nandrolone from Tornel and Denkall’s Decanandrolen, do not purchase any Deca In a strength of 200mg/ml. North America is the only region really known to produce nandrolone in such a strength. Everywhere else you should find only 50mg and 100mg per ml. Also be very leery of all 2ml ampules and vials that contain a total of 200mg (100mg/ml). Counterfeit producers always prefer to label their product as 200mg because if sells for a higher price, so be careful. At the same time 50mg ampules are an extremely safe buy. Counterfeiters virtually never duplicate 50mg ampules because they are in very low demand, and provide the dealers much less profit.

Although uncommon, all legitimate Organon vials/ampules of Deca-Durabolin® do not have to use a paper label. Ampules from various Asian and South American countries have been seen to bear only silk-screen lettering on the surface of the glass. Obviously avoiding all such ampules would not be an accurate rule to go by.
