While Patrick Mendes was sentenced to 2-year ban, Joshua Gilbert received 3-year ban

Patrick Mendes and Joshua Gilbert, top Olympic weightlifters, were banned from “Average Broz’s Gymnasium” (Las Vegas, Nevada). They tested positive for forbidden medications. Steroids were not the medicines administered by these athletes. They administered non-steroidal drugs that are also forbidden under Code of the WADA.
Patrick Mendes tested positive for banned medicines in February 2012 before the United States Olympic Team Trials for Weightlifting set who would represent the US at the 2012 Summer Olympics. He tested for HGH; as a result, he was sentenced to a ban.
Joshua Gilbert tested positive for the diuretic medicine furosemide at the 2012 National Weightlifting Championships. It was in March 2012.
Furosemide is a drug which is administered by those that take steroids in order to hide steroid use. Moreover, this medicine helps sportspersons to lose weight in order to correspond to certain weight categories.  Weightlifting, boxing and wrestling are sports where athletes belong to certain weight groups.
HGH and furosemide are products that are banned by the International Weightlifting Federation (IWF). The anti-doping system of the IWF meets criteria of the WADA Code.
The weightlifters Mendes and Gilbert were trained by John Broz. Broz lived and trained with the well-known 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 several methods to America. He founded own training gym in Las Vegas.
Mendes was sentenced to 2-year suspension. As for Gilbert, he was sentenced to 3-year ban.
The bans of these athletes are failure for “Average Broz’s Gym”. So, the greatest weightlifters were not allowed to represent their home country at the 2012 Olympic Games.
