Decadurabolin 10 ampoules/1 ml (300 mg/1 ml)


Decadurabolin (Nandrolone Decanoate, Deca) from Omega Meds is one of the most popular steroids over the past decades, having earned its reputation due to its pronounced anabolic activity and relatively low androgenic activity. Usually used by bodybuilders in the off-season to build muscle mass.



Nandrolone Decanoate causes surges in protein synthesis and nitrogen absorption by muscle cells, causing a sharp increase in muscle mass and strength. However, its anabolic nature is not equivalent to stronger compounds such as Anapolon, Dianabol or Trenbolone.

Thus, Decadurabolin is often taken simultaneously with other steroids for mass gain. Deka Durabolin gives an extremely voluminous appearance due to the high level of intracellular water retention that fills the muscle cells during the cycle.

  • Androgenic activity – 30% of testosterone
  • Aromatization (conversion to estrogens) is minimal
  • Liver toxicity is low

  • Duration of action – 15 days (half-life – 7 days)
  • Recommended dose – 50 mg every 5 days (optimal-minimum option)

Effects of taking Deka-Durabolin

  • Pronounced muscle growth (in one course you can gain up to 8 kg of muscle mass with minimal rebound phenomenon)
  • Strengthening bones (previously used to treat osteoporosis) and ligaments (stimulates collagen synthesis)
  • Elimination of joint pain due to increased production of synovial fluid (joint lubricant)

  • Increase in immune protection (applies even to people with AIDS)
  • Conversion to estradiol without aromatase enzyme
  • Improvement of intestinal absorption of amino acids and other useful substances
  • Nandrolone has a relatively low probability of side effects. As a result of low androgenic activity, such side effects as acne, baldness, hair growth on the body practically do not occur. Nevertheless, they are possible, as with the use of any steroid, but in the case of nandrolone, this happens only when the recommended doses are exceeded several times.

    Application and dosage of Deka-Durabolin

    This drug acts rather slowly. The anabolic effect during the course of Nandrolone unfolds gradually, while a significant, but not sharp, increase in muscle mass is observed. It follows that the nandrolone course should be longer than other anabolic drugs

    Solo course of the drug

    • The course of nandrolone usually lasts 8-10 weeks, and there are not rare cases when performing athletes use it for up to six months, gradually increasing the dosage.
    • The nandrolone course is recommended with the mandatory use of testosterone in order to avoid progestin effects and the consequences of low testosterone (low libido, weak erection).
    • Nandrolone injections are usually given once a week. Considering the period of activity – 15 days, there is no need to do 2 injections of Nandrolone per week. But if the weekly volume of administered drugs is large, it is often divided into two or three injections.
    • The recommended dose of nandrolone is 200 mg or more per week, and acquaintance with this drug should begin precisely with lower dosages. A conservative approach will allow you to assess the effect of the drug on your body and avoid possible problems. The maximum is 600 mg per week, however, as the dose increases, the risk of side effects increases. You can get great results if you do 2 courses with breaks in reasonable doses, rather than one in high doses.
    • Do not take a course longer than 8 weeks without additional drugs. For long courses, it is necessary to use chorionic gonadotropin. If hCG was not used during the long course, then it is necessary to take it at the end of the course before PCT, but not at the PCT itself.

    Combined course

    It should be noted that the solo course of Nandrolone has many disadvantages, in particular, a decrease in libido, slow activity, suppression of the production of own testosterone, etc. These disadvantages can be eliminated if testosterone is added to the course. This is the gold standard for the use of nandrolone, it is highly not recommended to use this drug without testosterone. Testosterone should be at least twice as much as nandrolone. Nandrolone is best combined with the following drugs:

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

    The most optimal course (doses per week):

    • 100-300 mg nandrolone decanoate.
    • 500 mg of testosterone enanthate or cypionate, or 500 mg of sustanon or omnadren
    • 1 tablet of Cabergoline and aromatase inhibitors as indicated

    Side effects

    Nandrolone Decanoate is notorious for its sexual side effects, including decreased libido and performance, often leading to erectile dysfunction.

    In addition, Nandrolone increases the level of prolactin, a lactation hormone that can reduce arousal or sexual interest. This combination of low nitric oxide and high prolactin often leads to disaster in the bedroom.
