    The course of taking Nandrolone Decanoate (Retabolil) for bodybuilders

    This drug works rather slowly. The anabolic effect of course reception of Retabolol is revealed gradually, at the same time a significant but not sharp increase in muscle mass occurs. It follows from this that the Nandrolone course should be longer than other anabolic drugs. When using equivalent doses and the same duration of the course, testosterone causes approximately twice as much weight gain. However, testosterone is characterized by a more pronounced rebound phenomenon.

    The beginning and end of the course refer to the first and last Nandrolone injections.

    • The Nandrolone course usually lasts 8-10 weeks, and athletes often use it for up to six months, gradually increasing the dosage.
    • The course of Nandrolone is recommended with mandatory use of testosterone to avoid progestin effects and the consequences of low testosterone (decrease in libido, weak erection).
    • Nandrolone injections are usually given once a week. Considering the period of activity of 15 days, there is no need to do 2 injections of Retabolol per week. But if the weekly volume of injections 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 with smaller dosages. A conservative approach will allow you to assess the effect of the drug on your body, avoiding possible problems. The maximum is 600 mg per week, but with an increase in the dose, the risk of side effects increases.You can get the best results if you do 2 courses with breaks in reasonable doses, rather than one course in high doses.
    • Do not take a course longer than 8 weeks without additional drugs. Chorionic gonadotropin should be used in long courses. If hCG was not used during a long course, it should be taken at the end of the course before PCT, but not at PCT itself.
    • To eliminate the activity of progesterone, it is necessary to include bromocriptine, also starting with the second and ending 2-3 weeks after the last injection of Nandrolone. They take 1.25 mg 2 times a day. Instead of bromocriptine, it is preferable to use more modern cabergoline at 0.25 mg every fourth day during the entire course and 2-3 weeks after it.
    • In addition, to restore the hypothalamic-pituitary-ovarian axis, clomid (clomiphene citrate) is used from the beginning of the last week of the course and ends 2-4 weeks after it at 50-100 mg with gradual withdrawal. Tamoxifen is not recommended because it increases sensitivity and increases the population of progesterone receptors.
    • To suppress prolactin production and reduce progestin activity, Winstrol can be included in the course from the second to the last week.
    • Testosterone boosters can be used instead of gonadotropin, but they are less effective.
    • For maximum effect, take a complex of sports nutrition for gaining muscle mass and observe a diet for gaining muscle mass.

    The course of Retabolil should be coordinated with a specialist.

    Side effects

    The most common side effects attributed to Nandrolone Decanoate are acne, temporary cessation of testosterone reproduction, elevated low-density cholesterol (LDL), elevated prolactin, potency (high doses).

    It has been noted that Nandrolone is able to bind to progestagen receptors (approximately 20% of the injected substance), this is due to the removed carbon atom in the 19th position. Practically all 19-nor anabolic steroids show progestin activity.

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

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