The residue that is definitely dried out or is insoluble could be sampled by Swab Method.
The fact that it is "almost biologically the same" must be evaluated from the toxicological assessment or at least within an risk assessment during scientific demo period the place this simple fact is even more (or not less than earlier) important than for CV.

If two or maybe more merchandise emerge as worst case, the solution with most affordable therapeutic dose turn out to be worst situation.
