Lab testing & certificates of analysis
Every quantitative claim on this site traces to a document on this page.
Each lot listed below has a certificate from a third-party laboratory, provided by our supplier and published here:
all 41 size options currently have one.
Every field on the certificates each guide covers, what
each test means, and the caveats on each one. Where a guide leaves out a lot we publish, it names that lot and says
why.
Some entries also link to AxisPharm's own copy of the
certificate on its website, marked “Lab-hosted copy”. On the date shown, we downloaded that copy and
compared it with the PDF here: the two files were identical.

Where the certificates come from
PepsMartUSA does not order these tests. Each certificate was issued by AxisPharm, LLC, a third-party
laboratory, and we publish it as our supplier, Protixa, provides it. Most are addressed to Protixa; some are
addressed to Cell Wellness, a separate company under the same ownership as Protixa. Every certificate lists
Protixa in its Brand Name field, and each is matched to a lot in the catalog by the lot number printed on it.
How to read a certificate
A complete peptide COA carries: LC-MS identity confirmation and purity with the
chromatogram, endotoxin (LAL) where applicable, the batch/lot number, the test date, and the
testing laboratory's name. The lot number printed on a vial's label is what ties it to a
certificate in this library.
For a field-by-field walkthrough, and what these certificates don't report, see
reading a certificate of analysis; for the methods
themselves, how peptide purity is tested.
