What type of Organon are you talkin about....English, portugese, Karachi, Nile, Durateson??????? THe only problem I have is with the POrtugese sust.......look out for easy peel off labels( bogus) and the lot and dates will be stamped if they are legit........good luck.
A safer bet would be to go with Omna;s the new stuff is exactly the same thing as sust....
