Second this.

Coming at MikeKY_noInsulin’s question from a different direction. The pattern that distinguishes a bad batch from an exit is behaviour rather than product. A bad batch comes with communication, a reshipment offer and a batch number. An exit comes with slower replies, pressure toward less reversible payment methods, sudden discounting, and the same reassurance repeated without any new information. The product tells you less than the correspondence does.

Bacteriostatic water quality matters for dosing arithmetic reconstitution. Not all BAC water is created equal:

• Should contain 0.9% benzyl alcohol as preservative
• Must be sterile and pyrogen-free
• Should come in a sealed, intact vial
• Check expiration date — yes, BAC water expires
• Store at room temperature, protected from light

I buy from a reputable medical supply company, not Amazon marketplace sellers. The $3 savings isn't worth the infection risk from unverified BAC water.

One thing that is still open after MikeKY_noInsulin’s answer:

What a vetting checklist should actually contain, as opposed to a list of things that are easy to fake?

Comparison of compounded dosing arithmetic delivery formats I've tried:

I use lyophilized vials for cost and stability. The reconstitution takes 30 seconds once you've done it a few times.
