What a certificate of analysis contains

One certificate per sample, reporting potency against the label claim alongside identity and purity, plus the concentration you will actually be dosing.

Measured

  • Identity
  • Purity (%)

  • Within spec, below label, above label, or inconclusive

Concentration is derived and printed, not left for you to work out. A 10 mg label reconstituted with 2 mL should give 5.0 mg/mL; at 72% potency it gives 3.6 mg/mL. That is the number a dose is drawn against.

What the certificate does not claim

It attests to the sample submitted. It does not certify a vendor, a lot beyond the one tested, or future production, and it makes no representation as to safety or suitability.
