Horrible deal by Mankind from what I know about it. Leo is a much better business man than to make that mistake. They put themselves at the mercy of the big pharma by carrying the high production costs which are slowly eating them alive as Sanofi drags their feet with marketing. Cellceutix's drugs are much cheaper to manufacture and they should. have no debt to service like Mankind. Brilicidin is apparently very cheap to manufacture and so is Kevetrin.
