Nandrolone Guide: What To Expect, Cycle and Stacking Suggestions

Anabolic steroid and androgen Nandrolone is sold under the brand name Deca Durabolin. Nandrolone is an alternate term for (AAS). This medication was created mainly to treat anemia, cachexia, osteoporosis pain, and breast cancer. This steroid medication may be taken intramuscularly or subcutaneously if oral administration is undesirable.

Deca Durabolin is a well-known steroid brand name. In the 1950s, AAS were extensively utilized and are currently among the most popular. This steroid has several anabolic properties, making it a popular option among bodybuilders seeking to gain mass. Nandrolone has been outlawed since 1974, although it is still regarded as a controlled substance and used as a “doping agent.” Many sporting organizations, including the International Olympic Committee, have banned the use of this performance-enhancing medication. Deca Durabolin is used to treat a broad variety of health conditions, despite the drug’s continued medicinal utility.

What is Deca Durabolin (Nandrolone)?

Nandrolone is a well-known anabolic steroid that was first designed to treat malnutrition and certain deficiencies in the body. However, it was quickly realized that it was also incredibly successful in enhancing athletic performance, and thus it was adopted by the sports industry.

Organon originally synthesized nandrolone in the 1960s, but it did not become generally accessible until 1962. Its first ester was phenylpropionate, which was subsequently changed to Nandrolone Phenylpropionate, or NPP.

Later, it was found that the drug required an ester with a longer half-life, resulting in Deca Durabolin, whose ester is decanoate. Although there are various types of nandrolone and other products, Deca Durabolin (nandrolone decanoate) is the most well-known, commercially available, and commonly utilized.

It is somewhat more anabolic and much less androgenic than testosterone. As an example, testosterone has an androgyny ratio of 100, whereas nandrolone’s ratio is 37. This is due to the fact that nandrolone is transformed into DHN as opposed to DHT (Dihydrotestosterone) (Dihydronandrolone). Despite this, it aromatizes roughly 20% more often than testosterone and may increase blood sugar levels. progesterone has several side effects that are undesirable.

This drug is often utilized during the offseason/bulking phase since it raises weight, enhances strength, and promotes muscular development. However, it is only used during the off-season due to its water-retention properties. Despite this, it is extensively used during the offseason since it offers the body with high recovery rates, enabling it to deliver therapeutic benefits and help in the body’s adaptation processes.


Why Was Deca So Popular?

The nandrolone decanoate anabolic steroid is regarded to be of the first generation. It has been in use since the early 1970s, or maybe even the late 1960s. At that time, just a handful of anabolic steroids were readily available to the general population.

In Europe, Primobolan is widely utilized, although Testosterone and Dianabol are more prevalent in the United States. The name of one of them was Deca Durabolin.

Its easy availability and minimal danger of androgenic side effects likely contributed to its popularity in the bodybuilding scene.


However, the quality of muscle that may be gained while taking Deca is an usually underestimated impact of Deca. The muscular mass developed while using Deca is reported to be relatively permanent and simple to maintain, despite being rather watery. The “rollover,” as it is sometimes known, is very low. So you may not gain 20 lbs. in 6-weeks. However, you will not notice a 17-pound weight drop after discontinuing use.

Due to this characteristic, Deca is an ideal option for off-season usage.

Nandrolone Results From Usage

Deca is a very efficient muscle-building steroid. In addition to promoting red blood cell synthesis, it will promote the creation of insulin-like growth factor 1 and allow the body to retain more nitrogen.

The combination of these elements results in a huge gain in lean muscle mass and, to some extent, in total strength.

However, since the decanoate ester inhibits the release of the steroid, its arrival into your system will be spread out over a two-week period as opposed to occurring all at once.

The user just has to give one injection every seven days as a result. Additionally, this allows them to continue taking Deca for approximately 16 weeks with suffering zero risk.

Deca is not the most effective substance for improving strength. Similar to other anabolic steroids, it will increase your strength to a smaller but still discernible degree.

Numerous sportsmen use Deca Durabolin just for the positive impact it has on the physique. In addition to aiding in collagen formation, Deca Durabolin has a pain-relieving effect that is not totally understood.

Several athletes have experienced relief from severe joint pain and even tendinitis after using a tiny dosage of Deca with their TRT dose of Testosterone. This treatment was proven to be beneficial for both disorders.


People who take Deca are quite concerned about the drug’s side effects. If you want rapid muscle growth, Deca Durabolin is the supplement for you. Because it is a slow-release steroid, it will take between twenty-four and forty-eight hours for it to reach the body’s circulatory system. However, once it enters the body, its effects are nearly instantaneous. Within seven to twelve days, consumers should see a notable increase in their stamina and endurance. Instead of waiting for their muscles to alter first, users may instantly see and feel the supplement’s effects on their stamina and energy levels.

After one week of using Deca Durabolin, you should see an improvement in both energy and stamina. This will help you to lift greater weights and do more repetitions in less time without feeling as weary. Due to its delayed release, Deca Durabolin is a fantastic alternative for those who like to cycle for a protracted amount of time and grow muscle over a longer period of time, as opposed to merely for fast muscle gains. You will have one injection each week for a total of 12 weeks, followed by a break of the same duration, unless otherwise instructed by your doctor. If you want the finest effects, it is advised that you do not exceed 4 milligrams per kilogram of body weight. As a result, the balance of its anabolic effects will be maintained, and the adverse effects will be contained within the safest range feasible.

How Does Deca (Nandrolone) Work in The Body?

As one of the most effective anabolic steroids on the market, Deca Durabolin (Nandrolone) is used by bodybuilders all over the globe to aid in the development of high-quality muscle and enhanced endurance. Clinical studies have shown that Nandrolone has a higher percentage of anabolic effects than androgenic ones. Because it promotes protein synthesis and assists in the healing of tiny muscle rips, Deca Durabolin is a strong anabolic drug that may speed up the process of gaining muscle.

In addition, Deca Durabolin stimulates bone marrow and enhances red blood cell formation in the body, which both contribute to enhanced cell development and oxygenation. Nandrolone has the capacity to maintain and regulate the body’s positive nitrogen balance. This is owing to the fact that protein is constituted of nitrogen-containing amino acids. This is crucial since the fundamental component of protein, which is what builds up muscle tissue, is nitrogen.

The major androgenic impact of Deca Durabolin is a rise in testosterone levels, which facilitates fat loss and muscle growth. Deca Durabolin exhibits many additional androgenic characteristics. This steroid may hasten your recovery by decreasing the amount of cortisol that accumulates in your muscles. Anti-inflammatory cortisol may retard the healing process. If you want a quicker recovery, using this steroid may be beneficial.

It increases the appetite

As efficient as this steroid is in promoting lean muscle tissue development, its use during a cut may be hazardous.

Deca produces a huge rise in appetite, so you’ll be hungrier than ever and find it difficult to feel full. This is good for bulking, during which a calorie excess is beneficial for maximizing muscle growth.

Therefore, if you have difficulty gaining weight, this boost in hunger is advantageous. If you want to maintain a low body fat percentage, you may need to limit the number of calories you take from deca.

It Increases Size and Strength

During the off-season, a bodybuilder’s primary objectives are to increase his or her strength and muscular mass.

If you want to bulk up and become as strong as an ox, you should take Deca.

On a deca cycle, it is not unusual for users to acquire up to 30 pounds of solid muscle.

Studies have shown that even little doses of 100mg every 14 days may result in considerable gains in lean body mass.

It Promotes Nitrogen Retention

The action of deca durabolin on nitrogen is one of the primary reasons why it is so effective in promoting muscle growth.

Deca assists muscle cells in retaining more nitrogen, which is necessary for muscular development. Increased nitrogen retention promotes a more anabolic environment in the body, hence facilitating the creation of more muscle tissue.

It’s Excellent For Joints

One of the benefits of a Deca Durabolin cycle is its positive effect on the joints.

As they age, bodybuilders in particular have painful joints since they are heavier than the usual individual owing to carrying greater muscle.

Deca, on the other hand, is particularly advantageous since it increases collagen formation in the joints, making them more lubricated and flexible.

Collagen serves as a joint cushion and protective layer.

This leads to less pain and discomfort, greater flexibility, and better resistance to wear and strain.

Increases the Production of Red Blood Cells

The greater the number of red blood cells in the body, the more oxygen and nutrients are carried via the circulation.

What does this have to do with bodybuilding?

According to study, deca raises the quantity of red blood cells naturally in the human body.

This, in turn, enhances our circulation, general health, and athletic performance. This results in larger pumps and more endurance, enabling you to finish more sets and reps than previously.

Not Hazardous to Your Organs.

Numerous steroid compounds are very toxic, posing a threat to the organs, notably the liver and kidneys.

Deca, on the other hand, is much easier on the organs and is regarded as far less powerful.

If a PCT is utilized effectively in combination with your major, there should be no significant damage done.


Dosages and Cycle Recommendations

Continue reading to find out more about Deca Durabolin cycles and dosages.

Deca Only Cycle

This steroid is mostly used for bulking, however it develops just a limited amount of lean muscle mass. Consequently, it is often coupled with other androgenic anabolic steroids to improve the experience. Stacking numerous steroids throughout a cycle typically increases negative effects, such as cholesterol and blood pressure increases. In spite of this, stacking Deca Durabolin may mitigate some of its adverse effects on sexual health.

Due to the high testosterone levels that might induce erectile dysfunction while on them, Deca Durabolin-only cycles are unpopular among bodybuilders. In contrast, nandrolone is commonly provided in 400 mg dosages over a period of 8 to 10 weeks.

Cycle of Deca and Dianabol

Dianabol (methandrostenolone) is among the most popular anabolic steroids. It is well recognized for its mass-building properties. Dianabol and Deca Durabolin compliment each other effectively during a bulking cycle. The combination of Dianabol and Deca Durabolin will offer even greater effects. As a consequence, muscles will develop bigger and stronger.

Hypertension and liver damage are the two most frequent harmful side effects of Dianabol. Therefore, those who combine Deca Durabolin and Dianabol will not suffer a rise in these two side effects. This cycle is suitable for those who have previously taken steroids. They have already finished a testosterone cycle and acquired anabolic steroid resistance. Take 400 mg of Nandrolone daily for eight to ten weeks. In contrast, the Dianabol dosage should begin in the third week and continue until the fourth week. It should be 10 milligrams daily. In the future, the daily dosage of Dianabol should be raised to 20 mg till the cycle is complete.

This stack may add between 30 and 40 pounds of weight, a portion of which is water weight. The aromatase enzyme is stimulated by dianabol, giving these consequences. Due to the high quantities of progesterone in Deca Durabolin and the high levels of estrogen in Dianabol, gynecomastia is a possible side effect. An AI (anti aromatase inhibitor) should be taken to counteract the conversion of testosterone to estrogen. Consequently, this cycle was the most popular among classic bodybuilders in the past. It boosted muscle growth without androgenic side effects, enabling users to avoid male pattern baldness by avoiding steroid usage.

Deca with Anadrol Cycle

Dianabol and Anadrol (oxymetholone) are the same. It is a steroid administered orally with several muscle- and strength-building effects. Both Anadrol and Deca Durabolin are androgenic, therefore they compliment each other effectively. This is the fundamental reason why they are stacked. Anadrol increases nitric oxide production, which reduces the impotence caused by Deca Durabolin usage. Because increasing nitric oxide improves blood flow to the penis, this is the case. The ideal way to finish this cycle is by taking 400 mg of Nandrolone every day for eight to ten weeks. The dosage of Anadrol should be increased to 50 mg per day by the third week. By the fourth week, this dosage should be followed. Beginning in week 5 of the cycle, the daily dose of Anadrol should be raised by 100 mg. This should be carried out until the 10-week cycle has concluded.

There are several detrimental consequences of Anadrol on the body, especially on the heart and liver. This cycle is only for those with prior steroid experience. Anadrol may increase blood pressure due to its high content of nitric oxide, and it can also inhibit hepatic lipase. In addition, the elevated progesterone and estrogen levels generated by Deca Durabolin and Anadrol enhance the likelihood of developing gynecomastia during this cycle. In this instance, an aromatase inhibitor will not be able to prevent the estrogenic effects of Anadrol. To counteract the effects of estrogen, SERMs such as Clomid and Nolvadex are used. In addition, the reduction of testosterone that accompanies this stack needs a very robust PCT.

Cycle of Deca and Testosterone

Another strong anabolic steroid often used to stimulate muscle development and strength is testosterone. Due to its potent androgenic effects, which facilitate the breakdown of fat, it is also used as a cutting agent. This leads to fewer adipose tissue, which facilitates fat loss.

Testosterone, one of the safest anabolic steroids, has been used to treat TRT by men all over the globe. The FDA has also authorized testosterone, which is used by males worldwide (testosterone replacement therapy). This is one of the safest bodybuilding combos available, with minimal side effects. Testosterone and deca durabolin account for two of them. Nevertheless, the combination is incredibly successful since it changes body composition, adds at least 30 pounds of muscle, and considerably increases strength.

Daily dosages of 600 mg of testosterone and 300 mg of Deca Durabolin should be taken for 10 weeks. The risk of hypertension is not increased by bulking, however cholesterol levels and blood pressure may be altered and slightly elevated. Combinations of Deca Durabolin and Testosterone that are beneficial to the heart are available for purchase: They complement one another very well. Due to the androgenic nature of deca durabolin, Testosterone is an ideal supplement for those who choose to abstain from sexual activity while taking deca durabolin. In addition, unlike Anadrol, Testosterone does this without damaging your health in any other manner.

This cycle is especially advantageous for men who want to prevent gynecomastia, since an aromatase inhibitor (AI) may be taken to concurrently reduce estrogen and progesterone levels.

Combining Deca Durabolin with the potent anabolic drugs indicated above will maximize its effectiveness. One-cycle steroid use is possible, but will almost likely halve your gains. All of these anabolic steroids are compatible with Deca Durabolin, and stacking them for 8 to 10 weeks may result in an average growth of 30 pounds of lean muscle.

Risks and Side Effects

Deca has a variety of undesirable side effects that consumers should be aware of. Nandrolone decanoate, an anabolic steroid, has been sold under a number of brand names, including Deca-Durabolin, Decaneurabol, Metadec, and Retabolil, among others. The brand name Deca-Durabolin is one of them. Additionally, similar to other steroidal drugs, it may cause significant health concerns.

Deca is a helpful therapy for a variety of different medical diseases, including anemia, osteoporosis, and incurable breast cancer, among others. As a result, many individuals mistakenly assume that it is likewise safe to use for the aim of gaining muscle. In contrast, the medicinal doses of Deca-Durabolin are substantially lower than those generally ingested by bodybuilders. Patients may be given 50–100 mg of decadron per month, but bodybuilders often ingest 400 mg of decadron in a single week. This suggests that the negative effects of the steroid tend to be magnified when bodybuilders use it unethically or for a purpose not allowed by the manufacturer.

Estrogenic effects

The fact that a deca durabolin conversion produces extremely little estrogen is a given. Alternatively, aromatization might arise from it via different methods.

When contemplating a rise in estrogen levels, it is essential to consider the possible detrimental consequences. Among these side effects include gynecomastia, which refers to an enlarged breast gland in males, increased intramuscular and subcutaneous water retention, and lower levels of free testosterone. In instances such as these, however, these adverse effects are often well-managed due to the administration of anastrozole.

Increase in prolactin levels

The fact that nandrolone is a medicine that increases progesterone levels is one of the most significant drawbacks of taking this substance that cannot be ignored. As is well-known, this may result in a variety of problems for males, including gynecomastia, a drop in libido, and a loss of erection capacity.

Always keep a careful check on the progesterone levels in your body, as well as its sensitivity and rise, in connection to the nandrolone doses you are utilizing.

Cardiovascular problems

Nandrolone has been demonstrated to have a stronger deleterious effect on HDL than testosterone. In contrast, there is little evidence that it presents a serious harm to the cardiovascular system. Those who are very sensitive, however, should be aware of the danger.

Regarding the cardiovascular system, it is also important to remember that nandrolone may induce an increase in water retention, which leads to a rise in blood pressure. People with hypertension or a predisposition towards the ailment should not use it. Even otherwise healthy individuals should be aware of the need to control their salt and water intake.

Androgenic Effects

Deca-Durabolin is not a highly androgenic anabolic substance. Although it is about a third of the dose of testosterone, as previously said, this does not indicate that there would be no consequences. Due to the fact that nandrolone is transformed to DHN rather than DHT, finasteride or any other DHT inhibitor will be ineffective. Androgenicity may present itself in a multitude of ways, such as acne, greasy skin, hair loss, etc.

A process known as virilization may occur in females. This refers to the appearance of masculine features, which may include, among other things, a deepening of the voice, an increase in hair volume, or even baldness. The most effective method for preventing these adverse effects in female users is adjusting doses according to sensitivity.

Reduced Testosterone Production

Your body’s natural synthesis of testosterone will be fully blocked by deca durabolin, which is exactly why testosterone should be included into nandrolone cycles.

Low testosterone levels are associated with an increase in estrogen, a decrease in testosterone, a loss of lean mass, an increase in body fat, a decrease in sexual function, a decrease in desire, and sadness.


Deca durabolin is not very harmful to the liver. Although it is metabolized directly or indirectly in liver tissue like any other drug, its adverse effects are minimal.

You will not be required to take hepatoprotectives, but it is advised that you do so. Remember that the less damage you do to your liver, the better the outcome.

“Deca Dick”

Deca Durabolin’s notable sexual adverse effects include a reduction in sexual desire and performance, which usually leads to erectile dysfunction. These adverse effects have brought Deca Durabolin notoriety (Deca dick).

Due to its low androgenicity, Deca Durabolin may make it difficult for certain men to get and sustain an erection. Androgenic steroids facilitate the body’s production of nitric oxide, which is crucial for maintaining enough blood flow to the penis. In this sense, there is a risk that Deca Durabolin will restrict circulation.

In addition, Deca Durabolin raises levels of the lactation hormone prolactin, which has the potential to diminish sexual desire or arousal.

Low amounts of nitric oxide and excessive levels of prolactin are typically a formula for disaster in the bedroom when present together.

To offset this effect, however, many bodybuilders mix Deca Durabolin with an androgenic steroid, guaranteeing that their N.O levels stay raised. Examples of substances with androgenic characteristics include Testosterone, Anadrol, and Trenbolone.

Due to cabergoline’s propensity to lower prolactin levels by strongly binding to dopamine receptors, bodybuilders who use Deca may also opt to take cabergoline as a dietary supplement.

Deca Durabolin: Is it Safe For Women?

Deca Durabolin is one of the anabolic steroids that women may use in order to build mass and lean muscle mass.

According to research, Deca Durabolin is reasonably safe from a virilization standpoint. Despite the fact that Deca Durabolin may not be the most effective steroid for women (Anavar is a more popular chemical), this suggests that Deca Durabolin is quite safe.

Several studies indicate that females tolerate Deca Durabolin well when administered 100 mg every other week for 12 weeks (which translates to 50 milligrams per week).

However, research also indicates that Deca Durabolin may produce masculinization in women, even at extremely low doses and over a prolonged period of time. This is the danger associated with anabolic steroid use.

If a woman want to use Deca Durabolin, she should maintain her cycle as brief as feasible (preferably 8 weeks or less).

Final Thoughts

Deca Durabolin is a very powerful anabolic steroid that has been used by sportsmen and bodybuilders alike to enhance their performance. It may considerably increase your bodybuilding results when utilized appropriately. The steroid is suitable for women since it is less likely than other steroids to produce virilization.

However, it is impossible to prevent the adverse effects of Deca and other anabolic steroids. Before going all-in, you should begin with a modest dose and a brief cycle, particularly if you’re a beginner. This will allow you to observe the drug’s effects on your body.
