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.

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 15 orders across 3 vendors: average purity 98.7%, zero sterility concerns, 1 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.

Right, and one flattering data point from a group buy is not consistency. Consistency means separate batches, separately commissioned, over months.
