99.9% he will not be tested for roids pre employment, it would cost wayyy to much money, the drug screen is given before the actual academy, which most police academies have about a 60% graduation rate from the academy,, that would = lots of wasted funds that most pd's dont have...
Now for the bad news, most pd's will administer a polygraph exam and they will ask steroids, and if you try to read up on all those how to beat a polygraph websites,, welllll they ask about that too... poly boils down to hocus pocus garbage, but most pd's still use em.. that should be your buddies concern, not the drug test....
however for the physical he should be off everything for a while b4, because although they will not check hormone levels, they check everything else, meaning high red blood cell count high hdl ect. ect.
good luck to your [cough] buddy though, i think it is retarded that pd's are even worried about steroids you would think you would want an officer with an edge against all the doped out,
cranked up on speed perps that they have to face every day.....
tell your buddy stay clean for a month or two b4 the physical, and to just relax for the polygraph, all the poly senses is stress so relax........
