had my pre-joining medical today and everything went brilliant until it came to my urine! I had failed because of the high protein content found inside! i mean im not a body builder as such but protein does help you put on weight!! i was never made aware that i would fail for this purpose soo you can imagine being knocked back for this simple factor!! highly pissed off to say the least!! just curious as to why this would be a problem!?! any feedback would be greatly appreciated cheers.
