Nandrolone Decanoate 1 bottle/10 ml (300 mg/1 ml)


Nandrolone Decanoate from TN Pharma, unlike the majority of analogs known on the market, contains 300 mg of the active substance. The drug is excellent for gaining muscle mass and increasing strength. There are two important reasons to choose it: firstly, it is effective for most athletes regardless of gender, age and weight. Secondly, it is especially important that it is not hepatotoxic, i.e. not dangerous for the liver.



The main advantage of Nandrolone Decanoate is that it significantly increases protein synthesis in a short period of time, thanks to which the much-desired muscle growth occurs. This drug is very effective and powerful anabolic, which has many advantages over analogues.

Steroid profile of Nandrolone decanoate

  • Anabolic activity – 150% of testosterone
  • Androgenic activity – 30% of testosterone
  • Aromatization (conversion to estrogens) is minimal
  • Liver toxicity is low
  • The method of administration is injections
  • Duration of action – 15 days (half-life – 7 days)
  • Recommended dose – 50 mg every 5 days (optimal-minimum option)
  • Detection time – up to 18 months
  • Testosterone suppression – high (due to the progestin nature)

Effects of taking Nandrolone Decanoate

  • 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)
  • An increase in the erythrocyte mass of the blood, which leads to an improvement in oxygen transport. As a result, greater endurance
  • 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
  • The drug 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.

    Nandrolone course

    The medicine affects the athlete's body rather slowly. The anabolic effect of its use appears gradually, while the muscle mass increases significantly, but not sharply. That is why the course of use can be longer than that of analogues. It is worth noting that when taking equivalent dosages with the same duration of the cycle, testosterone increases muscle mass twice as much, however, the latter has a fairly pronounced rebound phenomenon.

    As a rule, the course of the substance lasts from 8 to 10 weeks. At the same time, cases are often recorded when professional bodybuilders make injections for up to six months, gradually increasing the amount of the drug. The tool is recommended to be combined with testosterone, this will reduce to zero the risk of developing progestin effects and encountering the consequences of a low concentration of male sex hormones, which include a decrease in libido and a weakening of an erection. Nandrolone injections are usually given once a week. Considering the activity period of 15 days, there is no need to do 2 Nandrolone injections per week.

    Compatibility with other drugs

    The solo course of retabolil 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 – very well combined with the drug.
    • Testosterone/Sustanon – at the same time, testosterone should be approximately twice as much as nandrolone, for example, 500 mg/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

    The main functions of Nandrolone Decanoate are:

    • increasing the production of protein, the main building material for muscle tissue,
    • suppression of glucocorticoid hormones,
    • positive influence on the synthesis of IGF-1,
    • increasing the duration of nitrogen retention,
    • increasing the concentration of red cells in the blood,
    • increasing the production of collagen, which has a positive effect on the condition of the skin,
    • increasing the amount of minerals in bone tissues.

    The first five factors are characteristic of most anabolic steroids. However, the enhancement of nitrogen retention in nandrolone is much higher than in analogues.This factor is very important for professional bodybuilders, since all muscles are 16% nitrogen. At first glance, this figure seems small, but it is worth understanding that abstinence provokes anabolism, and its absence, on the contrary, introduces the body into a catabolic state.

    Side effects

    It was observed that Nandrolone is able to bind to progestin receptors (approximately 20% of the administered substance), this is due to the removed carbon atom in position 19. Almost all 19-nor anabolic steroids show progestin activity.

    In addition, nandrolone caused the following side effects in studies:

    • Headache – 20%
    • Rhinitis (nasal discharge) – 15%
    • Back pain – 15%
    • Rash – 10%

    In addition, sometimes occur during the course: rise in blood pressure, abdominal pain, irritability, headaches, depression and some other complications.
