In the redacted documents from the USADA investigation of Lance Armstrong, several people are not identified still, rider 15 is never identified but his name is redacted out. Because they used a font that is not uniform width per character, there has been a lot of speculation over the years that rider 15 is Chris Horner because a.) his name fits the redacted space, and the parts of the characters USADA did not redact match the letters in Chris Horner, b.) the background described for rider 15 match Chris Horner.
Many people came to this conclusion separately. Someone who actually didn't dope and raced against Horner in his first prime wrote a lot about it - a sample http://stevetilford.com/2013/10/24/unbelievable-chris-horner...
There were lots of victims to various degree of the Armstrong era. Even on USPS people like Frankie Andreu were to some degree victims.
Chris Horner wasn't one of them.
Sure, you can get it. Where the "Advanced" part comes in is passing cat1 level blood and urine tests taken at random times in random places.
It’s not expensive once the infrastructure exists, the marginal cost is pretty small.
Chris "Redacted" Horner[1]?
The guy who "won" the Vuelta at 41? The guy who joined pro-continental teams only to have their race invitations withdrawn?
You can bet there are a lot of claims that Horner was a doper, and many claims that he was one of the worst.
Maybe Jonathan Vaughters's Tweet about him shows the utter contempt the pro peleton feels for Horner. Maybe Francisco Mancebo is hated more on the US circuit, but probably not.

I never saw anyone claiming Chris Horner was doping. He was not competitive internationally until his last years on the circuit when doping use somewhat subsided.
Chris Horner is the victim. In a better world it's Chris Horner who won Tour de France.
