"quantity found was nearly double that of the allowed amount"
So you are making an assumption that he took double the allowed dose ?
If this is for moi - I am not assuming anything.
Sample A has found 1900ng of Salbutamol. The limit for that specific substance is 1000ng's. That's nearly double and WAY beyond the two uses claimed, each containing 100ng's.
I will make an assumption, though it's just my opinion - the B sample will confirm the findings of the A sample.
Or perhaps i am wrong, perhaps the A sample got contaminated with 1700ng's of Salbutamol and the B test will prove this. Or perhaps someone is out to get the poor rider, as many dopers claim, and has spiked/rigged the results.
We shall find out soon.........
