Rebeca Gusmao steroids

Fresh on the heels of Rebecca Gusmao’s positive steroid test, the Brazilian Swimming Federation (CBDA) has just announced that another swimmer, Rogério Karfunkelstein, has tested positive for steroids.

According to a press release on the CBDA’s website (warning, press release is in Portuguese), a December 14 sample taken from Karfunkelstein tested positive for the steroid stanozol. According to the release, Karfunkelstein is banned for two years beginning December 14. The release goes on to say the swimmer claims to have taken the steroid while trying to rehab an injured knee.

Karfunkelstein, ranked 90th in the world last year in the LCM 50 breastroke, puts Brazil at risk of having its Swimming Federation suspended by FINA for 2 years. FINA rules state that if FINA gets positive results on four athletes within a period of 12 months, the Federation will be banned for 24 months.

In 2006, Renata Burgos also tested positive for stanozolol during the Brazilian championships.

Stanozolol is commonly sold under the brand name Winstrol, which comes in both oral and intramuscular versions Winstrol Depot. It has been approved by the U.S. Food and Drug Adminsitration/// for human use to treat several medical conditions, which include anemia and hereditary angioedema. In animals, stanozolol is used to improve appetite and promote muscle growth. Stanozolol is also known to improve red blood cell production and increases bone density in livestock.

Athletes who had been tested for stanozolol include Ukrainian heptathlete Lyudmila Blonska, who was also banned from her sport for life because she was found guilty of doping violations, testing positive for stanozolol twice, the first offense was in June 2003 and the second offense occurred at the recently concluded Beijing Olympics.

Other notable athletes who tested positive for this banned compound were sprinter Ben Johnson, slugger Rafael Palmeiro, and mixed martial arts heavyweight Tim Sylvia. Major League superstar Barry Bonds had been also accused of using stanozolol.
