Will clenbuterol show up in urine as a amphetamine drug for work?

It will not show up on the standard "drugs of abuse" profile. Employment, doctors physicals, military does NOT test for this.

If if it is specifcially tested it can be detected. It generally is tested on the drug panels done on athletes by organizations that ban it from competition. This is generally for international competitions such as the Olympics. The NCAA is reputed not to, however this is unknown.
