Sorry, "Sun Tzu .. extreme sources" etc... But it got your attention.

If we can debate rationally about this. I appreciate that you know US law and the rules that guide urine tests. If anyone asks about US tests I'll certainly point them your way. I know human biology and wish to advise also given that butterfly isn't undergoing a urine test in the US.

You quote excellent sources of information and prove your good intentions in doing so but I would ask that you check local law when giving guidance. We're all here to help, I hope.
