there are PLENTY who don't use. it's obvious the ones who use....they are the ones who put on 20+ pounds of muscle over an offseason, their head grows contorted and looks like Mickey Rourkes head, their feet get bigger. and oh yeah, their numbers get BETTER as they get closer to age 40. that would be Bonds, McGwire, Sosa, Giambi, Luis Gonzalez, Sheffield, and several others. but don't say everybody does, because they don't
Griffey Jr doesn't
Andruw and Chipper Jones don't
Jeter, Arod
Vlad Guerrero
etc etc etc
Bonds didn't need to test dirty, he ADMITTED it. and he DID test dirty for amphetamines, which is also an illegal drug.
