Stephan Bonnar And Dave Herman Fail Drug Tests

@Stephan Bonnar and @Dave Herman, who both competed at UFC 153 on October 13, have failed to clear post-fight drug tests.

The Ultimate Fighter’ season 1 runner-up, Bonnar, who lost to Anderson Silva in the main event of UFC 153 via TKO, tested positive for the anabolic steroid Drostanolone, announced his retirement from the sport after the bout.

Drostanolone or Masteron is an anabolic androgenic steroid that is a part of the dihydrotestosterone (DHT) family and commonly used in cutting cycles. Primarily used to treat breast cancer patients, it inhibits the production of estrogens by inhibiting the conversion  of testosterone to estrogen and is commonly used by amateur and professional sportsmen as it helps them gain from a more refined look to muscles. Since it is characterized by low water retention, muscle lines are more distinct and is commonly sold under the names, Masteron propionate and Masteron enanthate.

One of the most iconic names in Ultimate Fighting Championship history, Stephan Bonnar competed as a light heavyweight for the Ultimate Fighting Championship (UFC) and was the runner up on season 1 of The Ultimate Fighter on Spike TV. Best known for having never been submitted, he trained in Brazilian Jiu-Jitsu with the legendary Carlson Gracie and has also made appearances as an analyst on the ESPN2 series MMA Live and for UFC broadcasts on the FOX television networks. This is his second positive test for anabolic steroids, the first of which followed his UFC 62 defeat to Forrest Griffin in August 2006 in a fight that is regarded by many as the most responsible for attracting casual fight fans to mixed martial arts. Bonnar tested positive for the banned substance Boldenone and was given a suspension for nine months besides a fine of $5,000. The 35-year-old Bonnar announced his retirement from mixed martial arts a little more than two weeks after the loss and finished his career with a record of 15-8. The use of Drostanolone by Bonnar is seen by many as the reason why he so quiet about his retirement from mixed martial arts and allowed Dana White to make the announcement for him.

Dave Herman, tested positive for marijuana metabolites, the same drug for which UFC welterweight Nick Diaz is presently suspended. He was submitted by Antonio Rodrigo Nogueira in the co-main event of UFC 153 for his third loss in a row and also failed to clear a pre-fight drug screen issued by the Texas Department of Licensing and Regulation back in 2011 that makes UFC 153 his second failed drug test in less than two years. Dave Herman, an American mixed martial artist who competes in the heavyweight division of the Ultimate Fighting Championship, made his professional mixed martial arts debut on December 31, 2006. The UFC fighter fought for a variety of promotions including Bellator Fighting Championships, Shark Fights, and World Victory Road.

Marc Ratner, the UFC vice president of regulatory affairs, said twenty-two fighters out of 24 tested negative and two fighters tested positive. Punishments for the fighters will be issued sometime next week, Ratner said.
