Effective oral dose for the purpose of building muscle mass is a 15-40mg in period of not more than 6-8 weeks. This quantity is sufficient to see the effects. It is mostly used in definition period and pre-competition has a synergistic effect when taken together with testosterone. It has the ability to bind to SHBG (a substance that reduces the effectiveness of extracorporeal testosterone), releasing a greater amount of testosterone in the blood. Turinabol has a half-life of 16 hours, which is quite a long time for oral anabolic steroid. Therefore, it is necessary to divide the daily dose. Recent experience pointed to the relatively short period of steroid detection in urine - only 25-30 days. However, latest backstage information showed that athletes who have taken this favourite substance were positive after 33 days after its discontinuation, for which they received a disqualification for up to two years.
