Question

Not sure how to ask this but here it goes. Has anyone thought about doing a study on Horses that were socalled drugged durning there racing acreer. Either steriods or pthers. have these horse that were "superstars" on the track been the same in the breeding shead? Maybe just maybe after there first foals don't perform up to par and there stud fees drop there luster would stop shinning. Just a thought.
