Andre Berto is investigating conditions that must have led to his positives

The WBC welterweight champion Andre Berto tested positive for Nandrolone. The drug testing was conducted by the Voluntary Anti-Doping Agency (VADA).
 He had to fight against Victor Ortiz on June 23, 2012 in Los Angeles. This boxer agreed to submit to random drug testing before the match. T: E ratio method and carbon isotope ratio testing were used; they both indicated about intake of the anabolic steroid Nandrolone.
It was already the second time this month, when the VADA tested fighters and caught them administering steroids. The first boxer that tested positive this month due to tests conducted by the VADA was Lamont Peterson. He was scheduled to meet Amir Khan. It is quite ironically that Peterson requested random blood and urine testing. The drug test conducted by the VADA showed that exogenous testosterone was in system of Peterson several weeks before the fight.
Financial position of several companies suffered due to tests conducted by the VADA. For example, Golden Boy Promotions lost essential potential profit due to positives of Lamont Peterson. It was set by Richard Schaeffer, the CEO of Golden Boy Promotions, that the company lost 250, 000 dollars.
The cancelation of the fight between Andre Berto and Victor Ortiz will probably not influence greatly on financial position of certain promotional companies because Andre Berto will be possibly replaced by another boxer who will meet Ortiz.
Andre Berto didn’t explain why he tested positive. This fighter hired the attorney Howard Jacobs that would represent and defeat him.
Andre Berto claimed that he had never utilized steroids. Thus, he noted that he investigated with his attorney what could cause positives for steroids. Andre Berto concluded that he had never cheated; he succeeded in sport because of hard trainings and dedication.
The attorney Howard Jacobs represented numerous other athletes that turned out to be victims of fake food supplements.
It is confirmed that since Nandrolone has very long half life and it is detected easily, it is not very popular among doping sportspeople. But it has been defined many times that some dietary supplements contained the substance nandrolone which caused positives for steroids. But since sometimes not every ingredient is written on the label, sportspersons become victims of contaminated sport supplements.
