In his defense, he did say 'administered the test'.

I personally am interested to see where this goes, because it would benefit us all to see if the protocols and methods used by the labs are beginning to change because of the widespread use of substitution. Maybe they are securing the different brands, and when a UA sample comes in that matches exactly the chemical characteristics of a QF batch for example (exact same ph, SG, etc), it is subjected to further testing?

Healthy debate is good for all of us IMO.
