HUNTER: (On Camera) The company sold more than a million jars of Super Blue Stuff in justa few short years. But critics say that claims they're using to sell the product are a lot like the Emu, they just won't fly.

ROBERT NICOLOSI PHD, UNIVERSITY OF MASSACHUSETTS LOWELL: I was totally aghast, dismayed that, that something could make claims to that extent.

HUNTER: (Voice Over Tape) Professor Robert Nicolosi is a Biochemist at the University OfMassachusetts, and one of the only scientists in the world to have everactually studied Emu oil. The oil, he says, has, indeed, been shown tohave some health benefits. But so far, only in the ears of mice. Nicolosisays, Blue Stuff once offered to let him formally test their product in hisUniversity lab, but then never got back to him.
