In 1991 Brigitte Berendonk and Werner Franke, two opponents of the doping, published several theses which had been drafted former researchers in the GDR doping products which were at the Military Medical Academy Bad Saarow. Based on this work, in their book (translated from German as 'Doping Documents") they were able to reconstruct the practice of doping as it was organized by the State on many great athletes from the GDR, including Marita Koch and Heike Drechsler , who have denied the allegations. Brigitte Berendonk survived a 1993 lawsuit where Drechsler accused her of lying. The lawsuit essentially validates the book. [ improper synthesis? ]  
Anabolic steroids differ in their characteristics, which means there are steroids that are only suitable for specific uses. For instance, Trenbolone is not recommended for bulking but it is an outstanding fat burner. This makes it perfect for a lean mass cycle or a cutting cycle. Always take the side effects of a particular compound into consideration whenever you plan a stack. Do not combine anabolic steroids that show similar side effects. For example, never combine Anapolon and Dianabol because they are already quite toxic and if you combine them, the toxicity will increase exponentially and cause serious damage to your body.
