Deca Steroids | Deca Durabolin

Deca Durabolin

Deca Durabolin is the Organon brand name for the injectable steroid Nandrolone Decanoate. This was one of the first commercialized steroids, hitting the market in 1962. Deca Durbolin is one of the most commonly used steroids in the world due to the fact that it contains many favorable properties. Deca steroids are very similar to testosterone but it lacks the carbon atom at the 19th position. The result of this is a steroid that has a slightly weaker androgenic property than testosterone.

Deca Durabolin doesn’t break down into a potent metabolite in androgen target tissues. This is a problem with various types of testosterone as well. This metabolite is weaker than many types of testosterone, so it offers fewer side effects. It is possible for androgenic activity to become apparent with this type of steroid. However, it is known to shut down testoterone production and give users low testosterone levels.

Deca steroids have a lower tendency for estrogen conversion. For comparison, the rate has been estimated to be only about 20% of that seen with testosterones. 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 process.

Consequently estrogen related side effects are a much lower concern with this drug. An anti-estrogen is likewise rarely needed with Deca steroids, 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.

Deca Durabolin is a very safe choice among steroids. It is considered to be the very best overall steroid for a man to use when weighing the side effects and results. It should also be noted that in HIV studies, Deca Durabolin has been shown to be effective at safely bringing up the lean body weight of patients. It has also done well in boosting the immune system.

It is of note however that nandrolone is believed to have some activity as a progestin in the body. Although progesterone 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 well.

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 rate of fat storage and possibly gynecomastia. Many believe the progestin activity of Deca Durabolin notably contributes to suppression of testosterone synthesis, which can be marked despite a low tendency for estrogen conversion.

Deca Steroids are 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 rate 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 or twice per week. The dosage for men is usually in the range of 300-600 mg per week. It is believed that Deca Durabolin will exhibit its optimal effect at around 2 mg per pound of lean bodyweight weekly.

Deca Durabolin is also a popular steroid among female bodybuilders. They take a much lower dosage on average than men, usually around 50 mg 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.

Deca Durabolin Structure

Endogenous testosterone levels can be a concern with Deca Durabolin, especially after long cycles. It is therefore mandatory to incorporate ancillary drugs at the conclusion of therapy. An estrogen antagonist such as Clomid or Nolvadex is 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.

Remember not to begin post cycle therapy until after Deca Durabolin has been withdrawn for around three weeks. This is because it stays active for quite some time and 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 after use.

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 stubborn in leaving fatty tissue, particularly after heavy, longer-term use.

Some quantity of Nandrolone 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 stores are being actively depleted. 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.

Those not worried about drug screens 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 Durabolin and Winstrol 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 level of hardness and density to the muscles.

Deca Durabolin 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 or testosterone could also be substituted, producing greater results.

When mixed with Deca Durabolin, the androgen dosage can be kept lower than if used alone. You may choose to continue Deca steroids for a few weeks after the androgen has been stopped. This will 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-Durabolin therapy, so ancillaries are still needed.
