It was decades later that the secret behind this spectacular success became known. The East German Sports Federation had, with the help of the Stasi, used Performance Enhancing Drugs or PEDs to ensure that their athletes gained international recognition by winning the Olympic events. This systematic plan had been initiated in 1974 as a means to guarantee international glory through the achievement of gold medals at the prestigious sporting event. Oral- Turinabol , a testosterone derivative was used extensively to improve muscle mass and cut down recovery time. This allowed the German athletes to train harder and longer than other world athletes.
Stephan Bonnar and Josh Barnett , mixed martial arts (MMA) fighters from the UFC and PRIDE Fighting Championships , have also tested positive for the banned substance.  After the World Extreme Cagefighting show on January 20, 2006 Muay Thai turned MMA fighter Kit Cope also tested positive for boldenone.  Following the Strikeforce card on June 22, 2007 former PRIDE and UFC fighter Phil Baroni tested positive for boldenone, as well as stanozolol .  At a K-1 WGP event in Las Vegas on August 17, 2007 two fighters, Rickard Nordstrand and Zabit Samedov , both tested positive for boldenone.  Alexandre Franca Nogueira tested positive for boldenone in July 2008. 
If you are a tested athlete, if you’re going to supplement with anabolic steroids you must understand steroid detection times thoroughly if you stand a chance. For the tested athlete, you will be somewhat limited in-regards to which steroids you can use. For example, if you’re a truly tested athlete, Nandrolone based steroids can never be used as their detection time stretches past a year. Many testosterone compounds must also be avoided; especially large esters or testosterone mixtures, but the smaller or ester free versions are often an option. Of course, many athletes who are tested are only done so for show, and if that’s the case, well, it really doesn’t matter what you use. In any case, for show or a legitimate test, if you understand steroid detection times there’s really no reason for you to have a problem.
