Patrick Mendes and Joshua Gilbert were banned for intake of non-steroidal preparations

The top Olympic weightlifters Patrick Mendes and Joshua Gilbert were banned from “Average Broz’s Gymnasium” (Las Vegas, Nevada). They tested positive for prohibited medications. Steroids were not the drugs applied by these sportsmen. They administered non-steroidal products that are also forbidden under Code of the WADA.
Mendes tested positive for prohibited medicines in February 2012 before the United States Olympic Team Trials for Weightlifting defined who would represent the US at the 2012 Summer Olympics. The athlete tested for HGH; as a result, he was banned.
Joshua Gilbert tested positive for the diuretic product furosemide at the 2012 National Weightlifting Championships. It was in March 2012.
Furosemide is a medication that is used by those that apply steroids in order to mask usage of steroids. Moreover, this medication helps sportspersons to lose weight in order to meet criteria of certain weight groups.  Weightlifting, boxing and wrestling are sports that divide competitors to weight classes.
HGH and furosemide are preparations which are banned by the International Weightlifting Federation (IWF). The anti-doping system of the IWF is in the harmony with the WADA Code.
The weightlifters Mendes and Gilbert were coached by John Broz. Broz lived and trained with the celebrated Bulgarian weightlifter Antonio Krastev during his career. Krastev broke a world record snatch of 216 kg in 1987. John Broz learned the Bulgarian system of trainings and brought some methods to America. He founded own training gym in Las Vegas.
Mendes went to 2-year suspension. As for Gilbert, he was sentenced to 3-year suspension.
The suspensions of these athletes are failure for “Average Broz’s Gym”. So, the greatest weightlifters were not allowed to represent their native country at the 2012 Olympic Games.
