1) which cancers is it better at killing?????? I think we are way ahead of ourselves here. It hasn't proven to kill ANY cancer yet. It could be a total bust for all we know. I'm in big but a lot of that hinges on Prurisol. I like our chances there. Not knocking kevetrin. I'm just a realist....time will tell. My own personal opinion is we are at the base for CTIX...1.80 -1.85 until something news worthy....
