How to read a certificate

A certificate of analysis records what an analytical laboratory measured on one specific batch. It is not a general statement about the product line, and results from one lot do not carry over to another.

What appears on ours

  • Lot number, product, strength, and release date
  • Each test performed, the method used, and the result recorded
  • The testing laboratory and its report reference

If a figure you were quoted does not match the certificate for the lot you received, tell us and we will resolve it.
