What's the State of Knowledge or Awareness From Surveys?

We don't know, for instance, maybe if we only take metragenyn and now give some purified form to humans, how that is going to produce an effect.

And to chris's metaphoro, we don't know the note or the tenor or the tune or the tempo of all these different instruments, yet i'm let alone how they work in concert. We have a lot of work to do.
