What we publish
Batch documents are listed on the Lab Results page as they become available. Each entry names the product, the batch and the test date, links to the document, and can be found by searching for a product name or batch.
Not every batch has a published document. Where one exists it is listed; where it does not, the page says nothing about that batch rather than implying a result.
What a certificate of analysis tells you
A certificate of analysis answers two separate questions: is this the right molecule, and how much of the material is that molecule.
Identity
Usually confirmed by mass spectrometry, which checks the measured molecular mass against the expected one.
Purity
Usually measured by HPLC, which separates the components of a sample and reports the target as a share of everything detected.
A purity percentage is a ratio of peak areas under one set of conditions. It is not a statement about the mass of peptide in a vial, and it does not describe sterility or how a material has been stored since it was tested.
Checking a document against a product
- The product name and amount on the document should match the label.
- The batch on the document should match the batch you are asking about.
- The document should say who carried out the analysis and when.
Questions about a specific batch
If you need a document for a particular product or batch and cannot find it, ask through the contact page and we will tell you what is available.
