The useful checklist is about verifiability rather than presentation.

Genuinely useful, thank you. I had the facts and not the framework. Sending this to two other people who asked me the same thing last week.

Adding the clinical framing, because it changes how the question reads.

Shipping damage protocol for vendor vetting orders: if your package arrives with visible damage, temperature excursion, or broken vials:

  • Photograph EVERYTHING before discarding packaging
  • Note the temperature of the cold pack (liquid = possibly too warm)
  • Contact the vendor within 24 hours with photos
  • Request a replacement shipment or refund
  • Do NOT use potentially compromised medication

Reputable vendors will replace damaged shipments without argument. If they push back, that's a red flag about the vendor.

The pattern that distinguishes a bad batch from an exit is behaviour rather than product.

Vendor reputation tracking for vendor vetting: I maintain a personal spreadsheet with every order I've placed — date, vendor, batch number, Janoshik result, personal efficacy assessment (1-5 scale), and any issues.

After 20 orders across 5 vendors: average purity 97.4%, zero sterility concerns, 0 shipping issues (all resolved). This data gives me confidence in my current source and documentation if issues arise.

I encourage everyone to track their orders systematically. Community data aggregation makes us all safer.

The figures, for anyone assembling their own picture. The boring version of this is the one that works, and the boring version is: measure a baseline, change one variable, wait, measure again under the same conditions. Nobody wants that answer and it is still the answer.
