Turinabol (4-chlorodehydromethyltestosterone) is an anabolic steroid that is similar in effects and chemical structure to methandrostenolone. The word “oral” in the title means that this anabolic agent is taken anabolic steroids acne orally (orally). The difference from methandrostenolone is that turinabol contains an additional chlorine atom. The drug was first developed by the German pharmaceutical company Jenapharm and patented in 1961.

Androgenic activity – 50% of testosterone (moderately low)
Aromatization (conversion to estrogen) – absent
Liver toxicity – high
Method of administration – inside (in tablets)
Duration of action – 16 hours
Detection time – 8 weeks




The drug can be described as Methandrostenolone without the effect of fluid retention in the body. It is a delayed acting steroid. During the course of turinabol, weight, strength and relief progress very slowly, but according to the athletes, these results are of better quality.


Another distinctive feature of the drug is the absence of estrogenic effects (since it does not undergo aromatization, due to the addition udenafil fda approval of a chlorine ion to the molecule), that is, side effects such as fluid accumulation, gynecomastia, etc. are practically not found. Although there are reviews that report the development of gynecomastia, the mechanism of development of which remains unclear. The most likely reason is the presence of methyltestosterone in the composition, which is associated with the characteristics of the synthesis.


Admission course


During the preparation for the Olympic Games, the optimal dose of the drug was selected, which caused a minimum of negative consequences – 20-40 mg per day, divided into three doses, however, bodybuilders often neglect these figures, bringing the dosage to 100-150 mg per day. The drug can be used both for gaining muscle mass and for drying.


The course of turinabol does not require the inclusion of antiestrogen and gonadotropin (if it does not exceed 6-8 weeks). In view of the fact that the effect on the mass is not pronounced, the turinabol “solo” course is not considered preferable in bodybuilding, however, as the first course, the “solo” course is practiced in dosages of 40 mg, which leads to significant results, both in terms of gains in quality muscle mass , and in the increase in speed-strength results.


For gaining muscle mass hcg injections cost, a combined course of Turinabol (20 mg per day) + testosterone enanthate 250 mg per week (or + sustanon) is better suited. The average duration is 6 weeks. First, turinabol is canceled, and a week later enanthate.


Athletes who are not interested in gaining mass and seeking to increase speed and endurance (boxers, wrestlers, runners, etc.) are recommended lower doses – 10-20 mg per day. However, it should be borne in mind that recently turinabol has become a problematic steroid in terms of anti-doping control, since it has an admixture of methandrostenolone and can be determined up to 90 days due to the emergence of the latest equipment.


Side effects


Turinabol is a 17-alkylated anabolic steroid, which allows oral administration, but creates a toxic effect on the liver. In general, side effects are quite rare and are most often associated with an excess of the duration of the course and high doses. This drug moderately suppresses the secretion of its own testosterone.
