They are not contradictory, they measure different things, and this is the single most common misreading of a certificate.

Agreeing with Dr.RenalNash, and the qualification matters more than the agreement. One addition: an unstated method makes a report close to uninterpretable. "99% pure" without the technique, the standard and the conditions is a claim, not a measurement.

Agreed, with a caveat about community reputation: it is a lagging indicator.

Genuinely useful, thank you. I had the facts and not the framework. Printing the relevant bit and taking it with me.

I am more sceptical of certificates as a category than this thread is. The document tells you about a sample somebody chose to send, at a moment in time, and nothing about the vial in your hand. Independent purchase-and-test is a different quality of evidence and everything else is inference.

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.
