Indications and contraindications for use of Deca-Durabolin. Advantages of Deca-Durabolin over the other anabolic steroids. Risk factors, occurring during the use of Deca-Durabolin.

Deca-Durabolin Details


One milliliter of Deca-Durabolin solution for injections contains 25mg, 50mg, 100mg or 200mg of anabolic agent – Nandrolone Decanoate.

  • Molecular formula of Nandrolone Decanoate: C28H44O3
  • Molecular mass of Nandrolone Decanoate: 428.7
  • Chemical name of Nandrolone Decanoate: 3-oxo-estr-4-en-17 beta-yl decanoate.

You may find at retail:

  • Pre-filled syringes containing 1ml of Deca-Durabolin solution.
  • Glass vials containing 1ml of Deca-Durabolin solution.

Slightly yellow, Deca-Durabolin (Nandrolone Decanoate) oily solution should be used for intramuscular administration only.

Mechanism of action

Nandrolone Decanoate anabolic agent is a synthetic derivative of Testosterone. Just as all the other Testosterone derivatives, Nandrolone Decanoate stimulates the synthesis of muscle protein, improves calcium metabolism, accelerates the formation of erythrocytes in the bone marrow, maintaining high levels of nitrogen, as well as phosphorus, sodium and potassium chlorides in the body.

By causing these anabolic effects, Nandrolone Decanoate:

  • increases the muscle mass rapidly
  • accelerates the bone tissue growth
  • retains water in the body
  • normalizes hematological profile (in patients with anemia).

The advantage of Nandrolone Decanoate over the other Testosterone derivatives lies in that:

  • Nandrolone Decanoate androgenic activity level is low. Therefore, this anabolic agent causes androgenic side effects rarely (like virilization in women)
  • Nandrolone Decanoate provides a prolonged anabolic effect, which is why it can be used just once per week.

Indications for use

Deca-Durabolin injectable anabolic can be prescribed to adults and children over 3 years old. In children and adolescents, Deca-Durabolin must be used only under a strict and constant supervision of a physician.

Deca-Durabolin intramuscular injections can be used for:

  1. Treatment of aplastic anemia, anemia due to chronic kidney failure or anemia after a cytotoxic therapy.
  2. Prevention and treatment of postmenopausal osteoporosis in women.
  3. Prevention of osteoporosis in a prolonged use of corticosteroid drugs.
  4. Treatment of osteoporosis, when estrogen replacement therapy is contraindicated.
  5. Treatment of inoperable mammary carcinoma in women.
  6. Treatment of diseases, caused by negative nitrogen balance.
  7. Treatment of acute or chronic renal insufficiency.
  8. Regeneration of tissues after massive burns, severe infections and some other serious diseases.

It should be noted that in some countries, Deca-Durabolin was approved for the treatment of some diseases listed above, for instance:

  • In the UK, Deca-Durabolin was approved only for the treatment of osteoporosis in women during postmenopausal period.
  • In NZ, Deca-Durabolin was only approved for the treatment of postmenopausal osteoporosis and mammary carcinoma in women.

The largest list of indications for use of Deca-Durabolin was approved in Australia. In the USA and Canada, Deca-Durabolin anabolic had been sold within few decades and later was withdrawn from the market. Today, only generic Deca-Durabolin by PharmaForce is available in the USA, while in Canada, Deca-Durabolin generic drugs are not available.

The U.S. residents can buy generic Deca-Durabolin under nonproprietary name – Nandrolone Decanoate. On the international pharmaceutical market, Deca-Durabolin generic drugs are sold under various brand names. Retabolil is the most popular one.


Injectable drugs, containing active anabolic agent Nandrolone Decanoate (including Deca-Durabolin, Retabolil) cannot be prescribed to:

  • Children under 3 years old.
  • Pregnant or lactating women.
  • Men diagnosed with BPH or breast cancer.
  • Men and women with: heart failure; some kidney or liver pathologies (like porphyria, nephrosis); allergy to inactive ingredients found in solution for injections (like peanuts, benzyl alcohol) and allergy to Nandrolone Decanoate anabolic agent.

Even if Nandrolone Decanoate is not contraindicated to a patient, he should be warned about potential risks, requiring an immediate cancellation of this anabolic steroid. Thus, a patient should inform his doctor about any adverse reactions that occur after intramuscular injection of Nandrolone Decanoate.

Side effects

Deca-Durabolin anabolic steroid may cause reversible and irreversible side effects. Most side effects are dose dependent. Hence, the higher the daily dose of Deca-Durabolin, the higher the risk of severe side effects.


The most common side effects in women are menstrual irregularities (amenorrhea, oligomenorrhea), hypertrophy of the clitoris and virilization. The common signs of virilization are growth of hair on the face and body, deepening of voice, change of libido and acne. Virilization is an irreversible side effect, which requires an immediate cancellation of Deca-Durabolin.


The most common side effects in men are suppression of spermatogenesis, epididymitis, reduction of spermatozoa in the ejaculate, testicular atrophy, increased number of erections, prolonged (painful) erection, swelling of the breast tissue, benign prostate hyperplasia (BPH). A prolonged impact of Deca-Durabolin on male reproductive function may cause an irreversible male infertility.


Deca-Durabolin may slow down the growth of bones in children under 3 years old. In boys and juveniles, Deca-Durabolin may increase the penis size. Given that Deca-Durabolin may cause negative effect on normal growth and development of children, a child must be under a constant supervision of the doctor during the entire period of using this anabolic steroid.

Common side effects of Deca-Durabolin for men and women

Regardless of a patient’s gender and dosage of Deca-Durabolin, the following side effects may occur: nausea, hypertension, hyperlipidemia, decreased plasma levels of HDL cholesterol, increased plasma levels of hemoglobin, rapid growth of pubic hair, reduced urine flow or bladder irritation. These side effects are reversible, usually are mild or moderate and do not require cancellation of Deca-Durabolin.

  • When Deca-Durabolin is used as prescribed, its benefits for people’s health exceed the potential risks.
  • When Deca-Durabolin is used off-label, a healthy person may develop serious diseases, requiring a long-term treatment.

Deca-Durabolin Additional Information

Deca-Durabolin vs Retabolil

Retabolil is a pharmacological analogue of Deca-Durabolin, available on European pharmaceutical market. Retabolil solution for injections contains Nandrolone Decanoate anabolic agent, just as Deca-Durabolin.

Glass vials, containing 1ml of Retabolil solution are supplied to European market. The dosage of Nandrolone Decanoate in 1ml of Retabolil solution is 50mg. Other dosage strengths of Retabolil are not produced and not sold.

The producer and distributor of Retabolil (Nandrolone Decanoate) anabolic is Gedeon Richter. Given the fact that Deca-Durabolin and Retabolil contain one and the same anabolic agent (Nandrolone Decanoate), indications, contraindications and side effects of these anabolic steroids are identical.

Deca-Durabolin off-label use

Deca-Durabolin (Nandrolone) steroid is used off-label by bodybuilders and athletes just as many synthetic analogues of steroid hormones are. Deca-Durabolin anabolic steroid is a doping, which helps bodybuilders and athletes:

  • To stimulate the synthesis of protein in muscle tissue – thereby stimulating the fast growth of muscles.
  • To maintain high levels of nitrogen in the muscle tissue – thereby increasing the muscle strength and stamina.

Abusing Deca-Durabolin, most athletes do not know that serious side effects of this anabolic steroid may require a long-term treatment and rehabilitation.

Herewith, athletes must realize that if National or World Anti-Doping Agency will find traces of Nandrolone (or its metabolites) in their body, they will be either disqualified or (and) fined.


Considering that the use of Deca-Durabolin anabolic as a stimulant of muscle growth is restricted, athletes should increase their athletic performance by means of legal bodybuilding supplements only.

Bodybuilding supplements increasing the secretion of steroid hormones in the body are used as effective and safe stimulants of muscle growth.

Over-the-counter generic versions of Deca-Durabolin contain only natural active ingredients, providing moderate anabolic effect without putting an athlete’s health at potential risk.

If you want to buy a safe alternative to Deca-Durabolin (Nandrolone), but you have never used legal steroid supplements before, then you can get information on over-the-counter analog of Deca-Durabolin over phone or by email.

You can buy a legal alternative to Deca-Durabolin and ask your questions about real alternative to anabolic steroids any time you want in any country of the world.
