i'd be asking your SIL to get the name of this "blue" stuff her friend used. the only treatments i can think of with blue are the puregon injections and pregnyl injections - puregon pen comes in a blue case (so the needle thing), pregnyl has blue on the box.

some metformin doses have blue on the box as well...

they're the only ones i've been exposed to so far that have any relationship to blue...
