Hi and welcome, brand new member.
I can appreciate that "The standard in science, pharma, and regulatory agencies requires multiple methods of testing peptide drugs for contamination since they all have "blind spots" that need to be compensated for."
But are you stating here that JANOSHIK TESTS of GLPs etc are "conducted AFTER being filtered with a .22um syringe filter"?
... which would mean that every time we confirm our product purchases with a Jano test, we are not actually learning what's in our own (unfiltered) vials?
And that we are not actually using what we think we are UNLESS we filter it that way?
Because I have never, ever come across that piece of information.
Nor do I filter.
