1. What should you do if a product’s documentation specifies a diluent different from the usual default?

Ignore it and use bacteriostatic water anyway
Follow the documented, product-specific instruction
Mix both diluents together
Diluent choice never matters

2. Why might a CoA or label be worth checking every time, not just once?

It’s purely a formality with no practical content
It can carry batch-specific handling notes that differ from general defaults
All CoAs are identical across every batch
It only matters for the first vial you ever handle

3. Why is a lyophilized (freeze-dried) vial generally more tolerant of brief ambient temperature exposure during shipping than a reconstituted solution?

Lyophilized powder is always frozen solid regardless of temperature
There’s no liquid environment for degradation reactions to occur in
Lyophilized powder is chemically inert and cannot degrade under any condition
Reconstituted solutions are always more stable than powder

4. What should you check when a shipment first arrives?

Nothing — unpack it and use it immediately
Packaging integrity, cold-pack condition, vial condition, and transit time
Only the outer shipping label
Whether the box was addressed correctly

5. What is the purpose of building a repeatable six-step lab workflow (prep, reconstitute, label, use, store, log)?

It introduces entirely new rules not covered elsewhere
It ties existing best practices into one consistent, repeatable routine
It replaces the need for any institutional SOPs
It only applies to single-use vials
