Certificate of Analysis Library

Every batch we supply is independently tested in Australia by HPLC and LC-MS/MS to verify purity and identity. The third-party laboratory report for each batch is available below. If a batch has no report in this library, we do not sell it.

Laboratory supplies are the one exception. Bacteriostatic water is a diluent, not a peptide, so there is no purity or identity assay to run on it and no Certificate of Analysis to publish. It is supplied to pharmaceutical grade and listed here for completeness.

How to read a Certificate of Analysis

Each certificate in this library is issued by Ozcanium Analytics, an independent laboratory in Australia. The notes below explain what the figures on it describe.

01

Purity

add
The purity figure is the percentage of the total detected peak area attributed to the target compound. It describes the relative composition of the sample tested. It is not a grade, a score, or a rating. We publish the figure the laboratory reports for the batch, whatever that figure is.

How to verify a report

Every report carries a code issued by the laboratory. The check below runs on the laboratory's own site, independently of this one.

  1. 01 Copy the report code from any certificate below.
  2. 02 Paste it into the verification tool on the Ozcanium Analytics site.
  3. 03 The laboratory returns the report it issued against that code, including the compound and the certificate itself.
