The active ingredient in Apto-Turinabol is Chlorodehydromethyltestosterone.
Apto-Turinabol is a powerful derivative of Dianabol. As an oral steroid, it has a structural composition that combines elements of methandrostenolone and clostebol (4-Chlorotestosterone), sharing the same foundational structure as Dianabol but featuring the 4-chloro modification from clostebol. This modification results in Chlorodehydromethyltestosterone being a milder variant of Dianabol, exhibiting no estrogenic effects and significantly reduced androgenic activity compared to its more renowned counterpart. Although the anabolic potency of Apto-Turinabol is slightly lower than that of Dianabol, it achieves a considerably more advantageous ratio of anabolic to androgenic effects. Consequently, at any given level of muscle-building activity, Chlorodehydromethyltestosterone is less prone to inducing androgenic side effects.
For men: Generally, a clinical dosage of Apto-Turinabol is estimated at 5 mg per day, although precise prescribing guidelines are lacking. In athletic contexts, an effective daily oral dose typically ranges from 15 to 40 mg, administered in cycles that should not exceed 6 to 8 weeks to reduce the risk of hepatotoxicity. This dosage is adequate for noticeable gains in lean muscle mass and strength. Apto-Turinabol is primarily utilized as a pre-contest or cutting steroid in bodybuilding, as it is not regarded as a suitable bulking agent due to its lack of estrogenic properties. Athletes in disciplines prioritizing speed also prefer Chlorodehydromethyltestosterone, as it provides a strong anabolic effect without the burden of excess water or fat weight.
For women: A common clinical dosage of Apto-Turinabol is estimated at 1-2.5 mg per day, though specific prescribing guidelines are not available. In athletics, women typically take one 5 mg tablet daily, in cycles no longer than 4 to 6 weeks to minimize hepatotoxicity risk. At this dosage, virilizing effects are unlikely. Higher doses were often employed with female athletes in the former East German doping program, frequently resulting in significant virilizing side effects.
