4 questions about quality & suppliers.
A useful laboratory report identifies the sample, method, result, acceptance criteria, dates, laboratory and traceable report number. Even a genuine identity/purity report does not by itself prove sterility, endotoxin safety, dose accuracy, stability or clinical suitability.

HPLC separates and quantifies signals under a method; mass spectrometry helps identify ions by mass-to-charge ratio. Neither test alone establishes sterility, endotoxin control, vial fill accuracy, stability, potency in use, or suitability for injection.

Verify the report directly with the named laboratory using a traceable report identifier, and confirm that the sample and lot match. A valid report only supports the tests actually performed and does not convert an unapproved product into an approved medicine.

Red flags include “research only” products marketed with human dosing, no licensed dispensing pharmacy, copied or unverifiable reports, missing lot traceability, disease-treatment claims, and claims that HPLC alone proves injection safety.
