Dosing and purity: a vial that is 99% pure might contain 80% of its label claim if the other mass is water, counter-ion, and excipient. Purity and content are different. Both matter for different reasons.

The reasoning is more useful than the number, which is why I have shown it.

That is clearer than the version I had in my head. Thank you.

cohort_drift, post #5: I read post #3 twice before replying, because I had assumed the opposite. Comparing documentation quality: I have looked for the primary source twice and failed twice. Either it does not exist or it is somewhere I do not know to look, and I would like to know which. Go to post

This follows post #3 rather than contradicting it.

Multiple services on one lot: agreement across two independent laboratories is stronger than a high number from one. Our vendor pages deliberately mix services for that reason.

That matches what I have seen, for whatever a single anecdote is worth.

Appreciated. The plain phrasing does more work here than a longer post would.
