MLB said of 1,438 anonymous tests during the 2003 season, between 5% and 7% were positive. I will assume that this is much lower than the actual number of players of juiced during the season...I'll go ahead and say 40%. David wells was also quoted as saying "25 to 40 percent of all Major Leaguers are juiced". However, with all the scrutiny and testing going on now, I would say its at about 5% - 10% (not including growth hormone). Now imagine if you randomly sampled IFBB pros. I am guessing that probaby 65% - 75% would fail...that is compared to 5% to 7% in baseball near the height of the steriod era. Also, the average IFBB guy is taking much larger doses. So I'm not saying that it still doesn't happen in other sports, but to try to compare the IFBB to MLB, NFL, etc. in terms of drug usage is ridiculous.
