t-and-f: Tainted Iron Supplement

[Flowman21]

So CJ is blaming this tainted Iron Supplement.  
Couple of questions:

1.  How would he know that it is now tainted?  Did they test the supplement.?
2.  Why would someone taint an iron supplement.  I'm sure that steriods are 
expensive enough that people don't really want to be just giving it away.
3.  Hunter then explains that Marion didn't take any of the Iron 
Supplement.-Well, hell, according to his logic, it wouldn't matter if she 
did.  It was tainted.

It just smells.
