Man, I would be so worried about impurities and side reactions. A good example is the recalls of drugs because of nitrosamine contamination. If stuff like this already happens to the experts.

And what is with the whole galenics side? How to make sure the absorption is about right…

That is about the experience I have. I asked it for factual information in the field I work at. It didn’t gave correct answers. Or, it gave working protocols which were strange and would not be successful.
