Says sample was contaminated with Turinabol-anabolic steroid
Turinabol
Turinabol, also known as Tbol, Oral Turinabol, Oral Tbol, and 4-Chlorodehydromethyltestosterone, is an oral anabolic-androgenic steroid (AAS). It is a derivative of dianabol (dbol), but it does not aromatize into estrogen. In fact, it produces slow, quality gains with less side effects than methandrostenolone.

Tbol was introduced by the pharmaceutical company Jenapharm, East Germany in the 1960′s. The sole goal was to get a competitive edge for both their male and female athletes in the Olympics. It was said that the success of East German Olympians from the 60′s through the 80′s can directly be traced to Tbol use.
The East Germans called the ‘tbol’ doping program STASI14.25, and it was kept secret until the 1990′s when Germany was unified. In fact, it is one of the few steroids in history that was developed solely for performance enhancement purposes and not for medical use.
Currently, turinabol is marketed and sold only by UnderGround (UG) clandestine laboratories via the black market. There is no pharmaceutical or veterinarian production of this drug, and it’s unlikely there will be in the near future.
Tbol vs. Dbol
Although Tbol and Dbol are almost the same thing, the difference is that there is an added 4chloro alteration with Tbol, which differentiate the two steroids. Turinabol has a zero (0) androgenic rating and a mild 53 anabolic ranking. This means there is zero androgenic or estrogenic activity with tbol (no aromatization will take place); therefore, users can expect slow, dry gains. On the other hand, dianabol is the king of aromatization and users will add a tremendous amount of mass (much of it water), in a short period of time.
