As far as Kevetrin being effective as a stand-alon

As far as Kevetrin being effective as a stand-alone, I suspect that what is going to happen is what I intimated earlier -- that very early stage cancers may be defeated simply by harnessing the body's own powers when Kevetrin turns the guardian angel gene back on. But ENTRENCHED LARGE cancers may not be able to be defeated by a weakened body -- which is where the combination therapy will come in.

Of course this is assuming that Kevetrin does work the way we hope it does in humans.
