Why Third-Party Testing Matters
In-house data can be excellent and still be unverifiable. Independent testing removes the incentive problem entirely.

The incentive problem
A manufacturer testing its own material has a direct financial interest in the result. That does not make in-house data wrong, but it makes it unverifiable from outside, and unverifiable data cannot support a purchasing decision.
An independent laboratory with no stake in the outcome removes that structural conflict.
What independence actually requires
A named laboratory, on its own letterhead, with its own report number and contact details. A logo pasted onto a supplier-formatted document is not third-party testing.
The sample chain matters too: a certificate is only as good as the assurance that the tested sample came from the lot being sold.
How to verify
Match the lot number on the vial to the certificate and check the stated dates and analytical methods. If peptide mass-spectrometry data are actually included, compare the reported molecular mass with the expected value; do not infer those data from an HPLC identity result or ICP-MS heavy-metals panel. Ask for clarification when a method, result or date does not reconcile.
