Deca Durabolin (Nandrolone Decanoate)

DecaDurabulin Dosages Deca Durabulin Cycles

Deca Durabolin is an extremely popular anabolic steroid. It consists of the steroidal hormone Nandrolone and is attached to the large Decanoate ester. Numerous Nandrolone Decanoate versions have hit the market since 1960s, but Deca Durabolin remains the most recognized and it dominates the Nandrolone marketplace.

Among performance enhancing athletes Deca Durabolin is one of the most commonly used anabolic steroids. It is tremendously beneficial as an off-season mass steroid and it’s also a favourite for its therapeutic benefits. Due to that, the Nandrolone hormone is also one of the most beneficial anabolic steroids in medicine.

Deca Durabolin Functions & Traits:

Deca Durabolin is a 19-nortestosterone anabolic androgenic steroid (19-nor). Structurally this is the testosterone hormone without a carbon atom at the 19th position. Hormone’s releasing activity is slow, which allows the individual to use it without needing frequent injections. When injected, the Decanoate ester detaches and there will be a spike in Nandrolone released within the body during the first 24-48 hours. After that, the hormone will continue to release into the body for another 2-3 weeks.

Deca Durabolin carries a slightly greater anabolic rating, than testosterone. Its total androgenic activity is much lower than one from a testosterone. It carries an androgenic rating of only 37 (testosterone has 100). This is due to the its ability to reduce to dihydronandrolone (DHN) rather than dihydrotestosterone (DHT), which makes it a much milder steroid. Therefore, it is also one of the most well-tolerated anabolic steroids for healthy adult men. Deca Durabolin aromatizes, but only at approximately 20% the rate compared to testosterone.

Deca Durabolin has the ability for protein synthesis enhancement, glucocorticoid hormones inhibition, and enhanced IGF-1 output promotion. It can greatly enhance nitrogen retention in the muscles, even with low doses of Nandrolone. This is important, since all muscle tissue has approximately 16% of nitrogen. The more we retain the more anabolic we remain; if nitrogen levels are not maintained, one may enter a catabolic (muscle wasting) state.

Deca Durabolin is also known for its ability to increase bone mineral content and enhance collagen synthesis. Therefore, Deca Durabolin is well known for promoting joint relief. For many athletes that’s the main reason they’ll use it. Those two traits plus its ability to increase red blood cell count are important therapeutic advantages of this steroid.

Deca Durabolin is also an excellent steroid for muscle wasting diseases, for improving geriatric weakness and fatigue, as well as anemia. It has been used to treat certain forms of breast cancer, it proved to be life changing for severe burn victims, and it has the ability to treat ulcers. It is effectively used for treating pituitary deficient dwarfism and development retardation in children. Deca Durabolin has proven beneficial in all these conditions and it has shined is in its ability to treat osteoporosis. If we consider the bone mineral content and collagen synthesis improvements, this isn’t a surprise. It is also used for therapeutic rejuvenation plans, it could provide a positive anti-aging benefit at a low dose.

Effects of Deca Durabolin:

The therapeutic benefits of Deca Durabolin are quite straightforward simply by understanding its basic nature. But Deca Durabolin is also a long-standing favourite for performance enhancing athletes. It is used as a bulking steroid, some competitive bodybuilders will also use Deca Durabolin during their cutting phase. Steroid progress is based on the enhancement of lean muscle tissue, but it has also other beneficial purposes. Let’s have a look at the positive effects of Deca Durabolin.

In off-season, Deca Durabolin will cause significant gains in lean mass. The increase in muscle mass will come slowly since this is not a fast acting ester based steroid. However, muscle mass built with this steroid will be of higher quality compared to many anabolic steroids. A possible water retention should be easy to control. Most also find their strength increases, but it is not one of the stronger strength increasing steroids. In off-season phase, the individual will also enjoy the therapeutic relief due to the use of this steroid. There will also be new growth with less body fat accumulation. The use of anabolic steroids, including Deca Durabolin, is well noted for enhancing the metabolic rate.

Many athletes, ball players, fighters, and other who could benefit from the therapeutic relief, often supplement with Deca Durabolin. They have no desire to build any new lean muscle mass, but the relief alone is invaluable and can be obtained by a very low dose. A slightly higher dose will provide more relief, enhance overall recovery and muscular endurance. The relief effects are not masking (such as with over the counter painkillers or prescription painkillers like opiates), Deca Durabolin can actually heal the body.

In a cutting phase, some athletes and bodybuilders will use a rather low dose of Deca Durabolin for the relief and muscular endurance it can provide. This can be very beneficial during hard diets that are brutal on the human body. It will also greatly preserve the individual’s lean muscle mass that could be lost during a caloric deficit.

Side Effects of Deca Durabolin:

For men, Deca Durabolin is one of the more side effect friendly anabolic steroids. For women, it can be useful but only in therapeutic level doses. Possible side effects of Deca Durabolin exist, but are far from guaranteed. With responsible use, most will not encounter any negative effect. You need to recognize the possible side effects of Deca Durabolin and what you can do about them.


If is is not very estrogenic, but it carries a slight aromatizing nature. This refers to testosterone’s ability to convert to estrogen. Rising of estrogen can promote gynecomastia, excess water retention and even high blood pressure. The aromatase level of Deca Durabolin is low, but Nandrolone has a strong affinity for the progesterone receptor and it can significantly stimulate the estrogenic mechanism in the mammary tissue which increases the risk of gynecomastia.

Anti-estrogen medication is recommended for protection from the possible estrogenic and progesterone related side effects. The choices are Selective Estrogen Receptor Modulators (SERM’s) such as Nolvadex (Tamoxifen Citrate) and Aromatase Inhibitors (AI’s) such as Arimidex (Anastrozole). SERM’s should be your first choice and if they can get the job done AI’s will be far more effective. AI’s do have a negative impact on cholesterol, while SERM’s have actually been shown to improve cholesterol levels.


Deca Durabolin can produce androgenic side effects like acne, accelerated hair loss (if predisposed to male pattern baldness) and body hair growth. Most men should find no problems exist since Nandrolone is reduced to DHN rather than DHT, which greatly reduces the androgenicity of Nandrolone.

Many supplement 5-alpha reductase inhibitors like Finasteride to fight with androgenic side effects, but in case of Deca Durabolin this will enhance the steroid’s androgenicity. It will do the opposite: it will increase the risk of androgenic side effects.

For female users, Deca Durabolin’s androgenic nature may lead to virilization symptoms, that can include body hair growth, a deepening of the vocal chords, and clitoral enlargement. At low doses women would probably not encounter any of these virilizing effects, but there are often better steroids for females to choose. If these symptoms occur, use should be discontinued immediately, and symptoms will fade away. If ignored, they may become permanent.


Deca Durabolin can have a negative impact on cholesterol, both HDL and LDL ratios. The Nandrolone hormone will most probably have even stronger negative impact on HDL cholesterol than testosterone.

Due to the cholesterol issues, maintaining a cholesterol friendly lifestyle during use is extremely important. This includes a cholesterol friendly and rich in omega fatty acids diet and plenty of cardiovascular activity. You will need to give your cholesterol even more attention if you use an Aromatase Inhibitor when supplementing with Deca Durabolin. You are encouraged to keep an eye on your cholesterol levels throughout the duration of use as well as post use.


Like all anabolic steroids Deca Durabolin is suppressive to natural testosterone production. With all Nandrolone based compounds, this will be extreme. A single 100mg dosing of this steroid might suppress total natural production. Therefore, all men who supplement with Deca Durabolin should include exogenous testosterone to provide the body with the testosterone it needs. Failure to do so will result in a low testosterone condition that comes with numerous possible symptoms and is extremely unhealthy.

At the end of Deca Durabolin cycle and all the exogenous steroidal hormones have cleared your system, natural testosterone production should begin again. It is recommended to introduce a Post Cycle Therapy (PCT) plan that will speed up the recovery process. Total recovery will take several months, but a PCT plan will ensure you have enough testosterone in your body.

Important note: a PCT plan should not begin until Deca Durabolin has been discontinued for at least 2-3 weeks.


Deca Durabolin is not hepatotoxic and will present no stress or damage to the liver.

Deca Durabolin Administration:

Deca Durabolin is a slow acting steroid and you don’t have to inject it all that frequently. In therapeutic treatment plans it is only administered once every 2-4 weeks or even every 3-4 weeks. When treating anemia Deca Durabolin is administered more frequently, like once per week. For performance enhancement, a single injection once a week will be more than enough. Some might choose to split it into two smaller injections.

The standard dose of Deca Durabolin for basic therapeutic treatment will normally be 100mg every 2-4-week range and for the treatment of anemia 100-200mg per week. For rejuvenation and relief, 100mg per week is a starting point, however, most will be much happier with 200mg per week results. For anabolic gains, 300mg per week is considered the low-end dose, 400mg per week will be considered as the perfect dosing level for many and still well within a controllable level. Doses as high as 600mg per week can be tolerated but this will increase the risk of side effects.

As a performance enhancing tool Deca Durabolin should not be used for less than 8 weeks, due to compound’s slow acting nature. Once discontinued it will still be active in the body for several weeks. 10-12 weeks cycle will be still very acceptable for most men and this is quite often the maximum. Stretching past this point is not recommended unless in hard-core performance circles, and even there, a rotation of steroidal hormones is highly advised.

For women athletes, 50mg per week for no more than 4-6 weeks is normally all that can be tolerated. Some might be able to handle a 100mg per week dosing, but it will normally produce virilization symptoms. For standard therapeutic treatment plans, it will normally be administered at 50-100mg every 3-4 weeks and in the treatment of anemia, 50-100mg per week.
