Uh, dont know your well informed vet is but T-breds die way more then Standardbreds, there's a year U.S. list out there somewhere, but last time i read it, it was at least 5-1, and they are lucky to race past 4 yes old, besides there are a lot of reasons any Racehorse can possibly die on the track or after a race that has nothing to do with any drugs, Colic, Tie up, and un diagnosed Anyerism, it's not always blood builders, or drugs, ect...
