Important! The “Your Trainer” website does not sell or encourage the use of anabolic steroids and other potent substances. The information is provided so that those who decide to take them do so as competently as possible and with minimal risk to health.

The androgenic-anabolic steroid (AAS) nandrolone, synthesized in 1950, is still one of the most popular in strength sports today. There are quite a large number of nandrolone esters: propionate, phenylpropionate, laurate, undecanoate, hexyloxyphenylpropionate, decanoate. The most common of them are phenylpropionate and decanoate.

Today we will talk about nandrolone decanoate, presented in such preparations as: Deca-Durabolin (25, 50, 100 mg/ml.), Retabolil (25, 50 mg/ml.), Deca-Durabol (25, 50, 100 mg/ml. .) and many others.

Description Nandrolone Decanoate

Deca Durabolin, or retabolil, is an injectable form of the anabolic steroid Nandrolone. Nandrolone is similar in structure to the male hormone testosterone. The difference is the absence of a carbon atom in the 19th position (hence the scientific chemical name of the substance: 19-nortestosterone).

As befits testosterone, this form exhibits highly anabolic properties. Moreover, unlike other forms, the tissue-forming activity of Nandrolone testosterone is not accompanied by strong androgenic properties. This is due to the fact that the main part of Nandrolone is converted inside the body into a weaker form of anabolic - dihydroNandrolone. The androgenic activity of which is only 30 percent of dihydrotestosterone.

It is the mild androgenic effect of Nandrolone decanoate that explains the long-term popularity of Nandrolone among athletes around the world as the number one injectable steroid. It is chosen for its ability to support strength and muscle growth without pronounced hormonal side effects.

Nandrolone also exists in natural form. It is released in small quantities by the human body during periods of overcoming trauma and stress; during pregnancy in women. However, in pharmaceuticals, naturally, we are talking about its artificially synthesized analogue.

The synthetic form of Deca Nandrolone (DN) was isolated in the laboratory and first described in 1960, and within a couple of years it became a prescription drug. The first developer and manufacturer of the drug is the International Pharmaceutical Concern Organon (founded in 1913 in the Netherlands). From the very beginning, Nandrolone Decanoate was sold under the brand name Deca-Durabolin. In Eastern Europe - retabolil.

Deca-durabolin is an injectable form of Nandrolone phenylpropionate, made with the addition of a 10-carbon ester. This form significantly accelerates the release of Nandrolone from the site of administration into the body and its transportation. Thanks to this advantageous difference from similar analogues of the drug, we quickly and systematically expanded the market for these products. Probably, these properties explain the fact that it was the Organon version that soon became one of the most widely used steroids in the world and the use of Deca Durabolin became so popular

How to use

The effect of using the deck is noticeable already from 200 ml per week. Professional athletes sometimes use 800 ml per week. How smart this is is hard to say. Over the past five years, many athletes have begun to abandon nandrolone. Popular bodybuilders claim that this anabolic steroid has outlived its usefulness in terms of productivity.

However, there is fanaticism and the will to win in people, and therefore there are those who want to inject 1000 mg per week to establish new athletic heights. Thanks to Hungary, Deca is also known as “Retabolil”. In European countries and the USA it is known as “Deca-Durabolin”. The effect after injection lasts for 14-20 days.

The drug itself began to be used for medical purposes after heart attacks, operations and dystrophy. In women, the drug activates an increase in hemoglobin and a decrease in calcium. Sometimes the drug will really help a person recover after difficult periods. For example, the drug is injected in minimal doses by actors, stuntmen and even artists.

As for the political component, the IOC declared war on this steroid. The only other side of the coin is that the athlete must look for an alternative to recovery. They resort to using new, unstudied anabolic steroids that actually harm the body.

The decay period is very long, so we advise you not to inject more than once a week. People go to any lengths to get a beautiful, toned body.

Instructions for use of Nandrolone

The drug is available in the form of ampoules containing an oil solution. It is necessary to take Nandrolone for at least 4-6 weeks for noticeable results. Nandrolone must be injected intramuscularly, inserting the needle as deeply as possible (it is better to inject into large muscles, for example, buttocks, thighs). It is advised to increase the calorie content of your daily diet, be sure to include vitamins and minerals, since Deca Durabolin must be taken with a large amount of proteins, fats and carbohydrates, as well as other nutrients.

Nandrolone Decanoate dosage and course

The course of Deca Nandrolone is as follows:

For men, the best dosage to ensure qualitative changes in physique and strength gains is in the range from 200 to 600 mg. in Week. Nandrolone is taken over a course of 8 to 12 weeks. This dose has proven to be sufficient for most athletes to provide tangible, measurable gains in muscle and strength gains. It is worth noting that in building muscle mass, the effect of Deca Durabolin is very pronounced, but is not too dramatic.

Regarding use in women's sports, the most common and recommended dosage for women is 50 mg. during the week. In this case, the course of Nandrolone Decanoate usually lasts from 4 to 6 weeks. Although, as already noted, the substance is weakly androgenic, women who significantly exceed this dose may experience symptoms of masculinization. Those. activation of hair growth on the face and body, increase in muscle mass, deepening of the voice, etc.

Studies have shown good tolerability and minor or completely insignificant side effects of Nandrolone in women, if its weekly dose of a maximum of 100 mg is not exceeded. The studies were long-term and looked at the effects of taking an increased dose of the drug over 12 weeks. Even more long-term studies - a course of Deca Durabolin for up to 12 months of use, taking 50 mg every 2-3 weeks. also demonstrated an extremely low rate of side effects.

Combined courses of retabolil

It should be noted that a solo course of retabolil has many disadvantages, in particular decreased libido, slow activity, suppression of the production of own testosterone, etc. These disadvantages can be eliminated by adding testosterone to the course. This is the gold standard for using nandrolone; using this drug without testosterone is highly not recommended. Testosterone should be at least 2 times more than nandrolone. Nandrolone is best combined with the following drugs:

• Winstrol - goes very well with the drug.
• Testosterone/Sustanon - in this case, testosterone should be approximately 2 times more than nandrolone, for example 500 mg/week. testosterone and 100-300 mg/week of nandrolone.
• Methandrostenolone - with 200-300 mg/week of nandrolone and 20-40 mg of methandrostenolone every day, permissible only in combination with Testosterone.

The most optimal course (dosages per week)

:

• 100-300 mg nandrolone decanoate.
• 500 mg testosterone enanthate or cypionate, or 500 mg sustanon or omnadren
• 1 tablet Cabergoline and aromatase inhibitors according to indications

Side Effects of Deca Durabolin

Estrogenic: Nandrolone has a low tendency to convert into estrogens, female hormones. This probability is only about 20 percent. However, an increase in estrogen levels is still observed with high doses of the drug. Accordingly, this most likely causes the following side effects: fluid retention and accumulation of fatty deposits in the body; gynecomastia – growth of mammary glands in size.

To prevent these “side effects,” there are effective “antidote” drugs. Anti-estrogens such as clomiphene citrate or tamoxifen citrate have been used successfully to prevent estrogenic side effects. For the same purpose, an aromatase inhibitor drug can be used, namely Arimidex (or Anastrozole), which controls estrogen even more effectively by blocking its synthesis.

Androgenic: Any anabolic steroid can have androgenic side effects, including this one. The most common of them are changes in the structure of the skin, with the activation of its oily areas; acne (pimples and pimples); more intense hair growth on the face and body, with simultaneous thinning and signs of baldness on the head. This is for men.

Women need to be aware of possible manifestations of masculinization, from subtle to clearly noticeable. Namely, the appearance of a deeper voice, irregularities in the menstrual cycle, disturbances in skin texture, increased hair growth on the face and body, and an increase in the size of the clitoris.

Nandrolone is an anabolic steroid with lower androgenic activity in relation to tissue forming actions than drugs such as methandrostenolone (methandienone) or fluoxymesterone. It is also important to note that due to its weak androgenic nature and ability to suppress endogenous testosterone, a Nandrolone solo cycle can interfere with libido (sex drive) in men, reducing it. So it is recommended to take it with libido supporting or test booster compounds.

Liver toxicity: Unlikely. During more than half a century of use, no harmful effects of the drug on the liver have been observed. Nandrolone is not alkylated with Alpha/17; under certain circumstances it can cause increased stress on the liver. However, in healthy people there is no hepatotoxic effect (liver poisoning).

Cardiovascular: Theoretically, steroids may have a harmful effect by increasing cholesterol levels and the risk of atherosclerosis. They can also negatively affect blood pressure, potentially increasing the risk of heart disease and heart attack.

Therefore, people with high cholesterol or a family history of heart disease should be careful not to take high doses of steroids. But: a study of a group of patients who were administered 600 mg for 10 weeks. Nandrolone decanoate per week demonstrated a 26 percent reduction in cholesterol levels.

And this suppressive effect is in full agreement with much earlier studies examining the effect on cholesterol levels of Nandrolone decanoate in comparison with testosterone cypionate. In any case, Nandrolone decanoate has a significantly weaker effect on serum lipids than Alpha/17-alkylated agents.

Testosterone Suppression: Any steroid in doses sufficient to promote muscle growth will somehow end up suppressing the body's endogenous production of testosterone. Effect of Nagdrolone when administered 100 mg. per week for 6 weeks produces an approximately 57 percent reduction in serum testosterone. At a dose of 300 mg. per week, this decrease reaches, on average, 70 percent.

Without the use of substances that stimulate the body's production of testosterone, the level of this production returns to normal within 2-6 months after stopping steroids. It should be taken into account that long-term abuse of anabolic steroids leads to hypogonadism - a pathological decrease in the level of male sex hormones, which the body can no longer cope with on its own, without medical intervention.

Properties of the drug: general characteristics

Content

Deca-durabolin is a drug, a long-acting anabolic steroid. The main active ingredient contained in the drug is nandrolone.

The structure of all anabolic steroids has much in common with the structure of testosterone, that is, the male sex hormone. But artificial drugs, of a kind, have great privileges, because you can build muscle with their help much faster.

Drug-Deca-Durabolin

The main properties of Deca-Durabolin include:

• androgenic properties – accumulation of male hormone;
• gain in body weight and strength;
• stimulation of fluid accumulation in tissues, which swells muscles;
• preventing joint damage;
• inhibition of cortisol receptors, which further increases muscle size.

It is worth considering that this effect will be noticeable in the case of adequate protein and calorie intake.

Availability

As a pharmaceutical product, Nandrolone decanoate has very rare and limited use in clinical medicine. Accordingly, its official production is very small. Most preparations of this substance on the black market are of “gray” or “clandestine” origin.

Today it is impossible to legally buy Nandrolone in the open market. But you can buy prohormones that provide the same benefits as AAS but are legal.

The history of its origin

Nandrolone phenylpropionate first appeared in 1957. After some time, it became a medicinal product and began to be produced under the name “Durabolin”. In the USA, it was prescribed for treatment and rehabilitation in the postoperative period with severe loss of muscle mass. In addition, it has been used to treat breast malignancies, osteoporosis, burns, malnutrition, and anemia.

Since 1970, the scope of the drug has been significantly narrowed. Today, this product is widely available in pharmacies, and its composition and concentration of the active substance may vary depending on the manufacturer, but it is mainly available in concentrations of 25 or 50 mg/ml.

Legal replacement for Nandrolone (Deca-Durabolin)

Since today the use of AAS is illegal and has many side effects, we decided to tell you about two legal drugs with a similar effect. These products are pro-hormones, have virtually no side effects and provide cleaner results.

Prohormones are safer and easier to use drugs, but never forget about using support and PCT during the cycle.

Special Recommendations

Despite the fact that this drug does not have androgenic properties, it should be recommended to the fairer sex with extreme caution.

Treatment with this drug can be combined with radiation therapy, as well as with cytostatics and glucocorticosteroids.

Particular care must be taken with glaucoma, epilepsy and migraine. During therapy, periodic monitoring of the condition of the prostate gland, intraocular pressure and liver function tests is required.

In the presence of a progressive malignant tumor, the duration of treatment is determined by the doctor and depends on the patient’s condition.

What is it needed for?

The instructions for Deca-Durabolin say that it is prescribed in the following cases:

• in conditions associated with protein loss (surgery, severe trauma, cachexia, burns);
• breast carcinoma (in women);
• osteoporosis.

In what cases is Deca still taken? Professional bodybuilders also actively use the drug. The active substance creates a positive nitrogen balance in muscle cells, that is, it increases muscle mass due to the accumulation of protein. In order for a bodybuilder to achieve the desired results, he needs to eat extra calories, supplementing his diet with proteins.

"Deca" has the ability to accumulate water in connective tissue. Therefore, Deca-Durabolin is a recognized remedy in bodybuilding. In addition, the drug in question relieves pain in the joints, and can even eliminate them completely. They often occur during strength training. “Deca” blocks cortisol receptors, as a result of which less of it reaches the connective tissue and muscle cells. Deca is also prescribed to strengthen bones, improve immunity, and increase red blood cell mass. Deca-Durabolin is also recommended for joints. The drug strengthens them, eliminates pain and unpleasant symptoms of the disease.

Contraindications

The medicine is contraindicated:

• if allergic to the active substance;
• patients with prostate carcinoma or hypertrophy ;
• for malignant neoplasms of the mammary gland in men;
• women with breast carcinoma with hypercalcemia ;
• pregnant women;
• with ischemia ;
• patients with severe atherosclerosis ;
• if the patient has a tendency to develop edema due to heart failure, chronic or acute liver and kidney diseases ( nephritis );
• during lactation;
• alcoholics and patients with alcoholic damage to the liver, kidneys or heart.

Interaction

Nandrolone phenylpropionate and decanoate enhance the effect of indirect anticoagulants, insulin, antiplatelet agents oral diabetes medications

Preparations containing sodium, corticosteroids , mineralcorticoids , and corticotropin increase water retention in the body and increase the likelihood of edema and acne.

The medicine weakens the pharmacological effect of somatotropic hormone and its derivatives.

The substance protects the liver when combined with hepatotoxic drugs .

User reviews

“Nandrolone Decanoate” has mostly positive reviews. Athletes note that the drug helps build muscle mass and reduces the percentage of body fat. When taken correctly, side effects rarely occur, and if they do, they manifest themselves in the form of headaches and back pain. An allergic reaction was observed.

Women practically do not use this medicine, and those ladies who use it note that in small dosages the androgenic property of the medicine is not felt.
