There is indeed a threshold for boldenone. Like TCO2's, an overage has to be quantified.
When it comes to Trainers facing Positives...IMO that's the single biggest problem we face in Harness Racing VOR.
It is a stone colt fact that there are a whole host of substances (I mentioned Bute in another post) that could not possibly be having any effect whatsoever at the levels at which they or their metabolites can still be detected...but nevertheless,as the rules are written a Trainer has a case to answer and can and will get time and/or a fine. Thresholds should be set for a range of therapeutic substances, above which a Trainer has a case to answer, below which they do not. Furthermore, it is my belief that levels must be provided in each and every case. Positives must be quantified. I'm surprised someone who has scored a positive for, again, Bute for example, hasn't taken it further for a quantitative report and then fought it on that basis. There definitely are testing testing methods available which indicate if it had been administered 12-24-36-48-72-96 hrs ago or more. They frequently use them in the US & CAN. Perhaps our Testing people already do this but because it is currently carried out on a Yes it is present or No it is not basis, they simply do not record/publish/pass on same?
