Nandrolone Decanoate Injections for Bodybuilding

Nandrolone decanoate injections for bodybuilding


Nandrolone is one of the most important steroids ever been used, apart from the basic testosterone, and has been among the leading compounds that have made it possible to develop all the exogenous (synthetic, that is) steroids as we know them today.

This anabolic steroid is to be found in the human body, although in very little amounts, and is mainly used in the pharmaceutical and veterinarian fields in a variety of different versions which, basically, differ one from the other because of the particular ester(s) attached to it.

The nandrolone was first released in 1960 by the company Organon, under the variant known as nandrolone decanoate (or “deca”, as it is called commonly). In fact, Organon developed it and named it Deca Durabolin, and soon after its release this anabolic steroid become one of the most used in the whole world.

Although it was the first time that the decanoate ester variant was released, it needs to be said that nandrolone itself was released on the market three years earlier, in 1957, which was the year when the variant known as nandrolone phenylpropionate appeared.

The main benefits of nandrolone decanoate are several, but its main feature – which pleases immensely those users who do not quite like injections – is that it requires a less frequent administration than most of the other steroids available when integrating it into a cycle.

Nandrolone decanoate is very available on the pharma markets, due to its widespread usage and acceptance,; its composition and dosages vary according to the country of origin and also to the manufacturer, but usually it comes in the 25 mg / ml, 50 mg / ml, 100 mg / ml, or 200 mg / ml dosages of the steroid’s active ingredient in an oil solution.

It must now be underlined that nandrolone decanoate is quite similar in its chemical structure to testosterone, only having one carbon atom less in the 19th position (which is why it is also known as a 19-nortestosterone). Such a modification is carried out in order to enhance the anabolic properties and lower instead the androgenic effects of this variant of the nandrolone. As such, the possible side effects like loss of hair, acne or increase in the body hair are rather not common (unless one exceeds the recommended dose of this anabolic steroid).

Nandrolone decanoate is also characterized by a strong spike of the steroid’s active ingredient, as it’s going to be released from 24 to 48 hours after it has been injected in the muscle – which release then progressively diminishes to almost the basal level. The half-life of nandrolone decanoate spans anywhere from 7 days to 12 days.

Another quite interesting feature of the nandrolone decanoate is represented by its rather low tendency to being converted into estrogens – which is about 20% compared to that of testosterone. This is the reason basically why it is not normally necessary to combine it with an anti-estrogen such as Nolvadex ® and / or Proviron ®). The collateral effects such as water retention and gynecomastia are possible only in those users that are genetically prone to those effects (but may well become a concern for the generality of users should this anabolic steroid be administered in high dosages).

For all the above stated reasons, nandrolone decanoate represents without a single doubt one of the most effective and least harmful anabolic steroids on the market worldwide.

However, nothing goes without carrying a potentially more or less dark side of its benefits, and nandrolone decanoate is by no means an exception to this rule. An important issue when administering nandrolone decanoate is that it does have a progestogen activity, which is basically due to some of its chemical features that make it prone to being absorbed by progesterone’s receptors. Hence, the collateral effects associated with the supplementation of this anabolic steroid are similar to those typical of the estrogens: the lowering in the production of endogenous (that is, the body’s) testosterone and the increase in body fat deposits, together with potential gynecomastia.

An additional issue carried along by the administration of nandrolone decanote is represented by its positivity when drug tests are in place, given that the usage of this anabolic steroid can be fairly well detected up to in general eight months after the last injection has been inoculated.

However, this compound does work quite well when integrated into a “slower burning” cycle which simply means that its release into the human body will occur at a slower rate when compared to a shorter ester compound.

These two combined advantages of nandrolone decanoate – the slow release time and the above stated reduction in the frequency of its administration – are indeed an additional value if compared to other compounds, as for example the phenylpropionate variant, but other than these two pluses, there are no other advantages that may be detected.

Now, in terms of the usage of nandrolone decanoate for bodybuilding purposes, it can be said that this anabolic steroid can be used either for cutting or for bulking cycles. It is often stacked with testosterone or with winstrol by those bodybuilders who want to pursue a rather common and yet very effective bulking cycle. The stack carried out with nandrolone decanoate seems to help those users who are prone to experiencing some joint issues when they are supplementing winstrol, while instead the latter seems to help many other users who want to avoid that progesterone would manifest itself in a build-up. Indeed, this supposedly great joint relief effect carried out by nandrolone decanoate represents without a doubt the reason why this anabolic steroid has become so popular among a plethora of athletes and especially in the bodybuilders’ circles all around the world.

Another androgenic side effect reported by users of the nandrolone decanoate is a rather frequent loss of their sexual appetite; it is hence recommended that the user take a little dosage of testosterone or an high androgen one as Proviron (which is the brand name for the androgen known as Mesterolone, an oral product that is not considered as a difficult to manage anabolic steroid because its anabolic activity is known as very weak) in order to help in the prevention of the said effect.

As mentioned before, nandrolone decanoate is not quite known as a very fast muscle mass builder – for example, if compared to an equivalent amount of testosterone, the nandrolone decanoate will in general provide a muscle weight of about 50% compared to that produced by testosterone. The muscle building effects are still rather noticeable, but not as high and dramatic as many other anabolic steroids on the market. It has slower properties in terms of its onset and progression, and it is exactly for this reason that nandrolone decanoate seems to be more appropriate for those longer lasting cycles. That is, cycles whose total duration will be anywhere between eight and twelve weeks, and an injection normally per week will suffice.



In terms of a general guide to dosing nandrolone decanoate, we can say tha the average dosage for men is usually in the range of 200-600mg – more specifically, it has been shown that the best gain vs side effect ratio of the nandrolone decanoate will be permitted by administering a male with roughly 4mg per kg of bodyweight on a weekly basis.

In terms of cycles for building muscle mass based on the nandrolone decanoate, we can now show you two distinct examples:

  • The first example is based on administering nandrolone decanoate and testosterone cypionate. This combination of the two anabolic steroids is of a mild nature and both together will help you get not only some noticeable muscle mass but also at the same time you will notice that the muscles you are building will be showing a more hardened aspect – while also keeping at bay your estrogenic levels
  • The second example is made of the combination of nandrolone decanoate, dianabol and test cypionate, and the inclusion here of dianabol makes this cycle a bit heavier than the previous example. You will get more muscle mass here and still have to deal only with some moderate androgenic effects.

Conclusively, we can say without any doubt that the implementation of nandrolone decanoate for bodybuilding purposes is a great choice already in itself. That is essentially because it does carry on a satisfying amount of muscle mass when implemented according to the above stated general guidelines, cycles and dosages, it entails a rather low risk of liver toxicity, and it also favors noticeable gains in term of strength while keeping your body fat % low.
