What I find interesting is under results is this:BroDeal said:A study about testing Clen levels in humans after eating beef injected with the drug (PDF):
http://proceedings.live-record.de/proceedings_2_pdf/2_185.pdf
It is just a few pages long.
"All urine samples collected before and between 4 and 6 hours......... In none of the analyzed samples norandrosterone or clenbuterol were identified. Nevertheless six of the samples showed unregularities in the screening window for clenbuterol. After breaking the sample codes it was shown that all these samples belonged to the 4-6 hours urine of experiment 1. The consumed meat in this experiment was from the calf treated with clenbuterol until one day before slaughtering."
Why would a farmer/cattle rancher administer a drug to cattle or plant prior to slaughter, it's neither rational or economically sensible to do so.
