just listened to an interview with Dick Telford (prominent Aussie distance coach / sport scientist at AIS) and he stands behind Pete 100%.....
Also - you can see all of Pete Bol's training on Strava - even the day he got tested. He does not go to training camps in far off countries where he cant be reached. Drug cheats are always secretive about their training/ whereabouts for obvious reasons. Pete is the exact opposite.
