Androstene converted to nandrolone once it was ingested, that's why it 
was banned. People who took enough of it were getting the same effects 
as those who were getting nandrolone from their local steroid dealer. 
I can tell you that a combination of HGH and steroids has a more 
immediate and pronounced effect on blacks than on whites. The effects 
show more slowly on whites (bodybuilders can tell you the same thing). In 
terms of steroids alone, different types have slightly different results 
depending on the race of the user. From my experiences with track and 
field athletes,  I can tell you that enforcement was not equal, blacks were 
routinely ignored or let off, results buried, etc.  People used to think I was 
blowing smoke, until the truth about Carl Lewis and others was finally 
admitted, where it turned out all the governing bodies were covering for 
Lewis and other black athletes. A lot of the same goes on with African 
athletes today, with people like Bernard Lagat caught red handed (my 
favorite example) and let off with spurious stories of "false positives" or 
people like Daniel Komen of Kenya, a multi record setter who when 
caught on one occasion was suspended for "excess caffeine" in his 
system. Sure. 
Whites have to be very careful. Blacks with big sponsorships will generally 
be protected. If Jones' coach hadn't started the whole mess by ratting out 
some other runners, officials would still be covering for her now. The 
"rumored" story is she'd tested positive on numerous other occasions. 
Maybe it's just a rumor, maybe not. But don't forget, she hired Johnny 
Cochran while she was in High School to defend her on a steroid mishap. 
I believe she claimed she'd "forgotten about" or "accidentally missed" a 
steroid test. Yeah, right. People that saw her run in HS said she looked 
juiced. I'm one of them. You can "google" the Cochran connection and see 
she's been fishy for years. He's the one who was first on the scene when 
her ex-husband was popped for juicing. 
Blacks are more likely to abuse 'recreational drugs' so they're sure as hell 
more likely to dope in sports.
