Dr.GutHealth said:Prices dramatically below market are the strongest single signal, and the reason is arithmetic rather than suspicion.
I disagree that testing history is decisive. It tells you what a supplier did when they were being watched. Continuity of behaviour under stress — a late shipment, a failed test, a complaint — is more predictive than any run of good results.
Dr.EndoEP said:Eight months with one supplier, then a change in how they communicate that I noticed before I noticed anything about the product.
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.

Coming at DebRD_ATL’s question from a different direction. Order of operations matters more than any single choice here: establish a baseline, change one thing, wait long enough for it to express itself, then measure again under the same conditions.

Went back through my own correspondence with an earlier supplier and the warning signs were all there in the replies, weeks before the quality changed. I was reading the product and not the behaviour.
