Turinabol active substance is 4-Chlorodehydromethyltestosterone.
Chlorodehydromethyltestosterone is a potent derivative of Dianabol. Turinabol is structurally a cross between methandrostenolone and clostebol (4-chlorotestosterone), having the same base structure as Dianabol with the added 4-chloro alteration of clostebol.
This alteration makes Turinabol a milder cousin of Dianabol, the new steroid displaying no estrogenic and much less androgenic activity in comparison to its more famous counterpart. The anabolic activity of Turinabol is somewhat lower than that of Dianabol as well, but it does maintain a much more favorable balance of anabolic to androgenic effect. This means that at any given level of muscle-building activity, Turinabol will be less likely to produce androgenic side effects.
A common clinical dose of Turinabol is estimated to be 5mg per day, actual prescribing guidelines are unavailable. In the athletic arena, an effective daily dosage falls in the range of 15 - 40mg, taken in cycles lasting no more than 6 - 8 weeks to minimize hepatotoxicity. This level is sufficient for measurable increases in lean muscle mass and strength. This agent is most often applied as a pre-contest or cutting steroid for bodybuilding purposes, and is not viewed as an ideal bulking agent due to lack of estrogenicity. Athletes in sports where speed tends to be a primary focus also fine strong favor in Turinabol, obtaining a strong anabolic bendit without having to carry around any extra water or fat weight.
