Labelled 10 mg / 8.87 mg peptide / 88.7% of label
The container was labelled 10 mg and held 10.23 mg of powder when weighed. Net peptide content of that powder is 86.74% w/w, so the peptide in the container is 8.87 mg.

This is the SHA-256 of the certificate file exactly as it was issued. Run the command against the file you were sent: if the two strings match, your copy is byte for byte the one this laboratory issued.
A copy that has been re-saved, printed to a new file or passed through a converter will not match, because each of those produces a different file. Compare the certificate exactly as it was sent to you, or the copy downloadable from this page.
