What the results mean

Three independent checks on every batch

Read how we test
  1. 01
    Purity

    HPLC analysis

    The percentage of the sample that is the target peptide. Higher is better.

  2. 02
    Identity

    LC-MS confirmation

    Confirms the measured molecular mass matches the expected mass for the peptide.

  3. 03
    Cleanliness

    LAL endotoxin

    Measures bacterial endotoxin in EU/mL. A pass means the result is within the lab's limit.

What is a Certificate of Analysis?

A Certificate of Analysis, or COA, is the lab report for a batch. It shows the compound tested, the method used and the result, such as HPLC purity.

How do I match a certificate to my vial?

Compare the batch or report reference on your vial label with the reference on the certificate. If anything does not match, contact us and we will look into it straight away.

Can I request a certificate by email?

Yes. If you cannot find or open the certificate you need, email us with the product name and we will send it to you or let you know when the report for the current batch will be ready.
