Four data points to look for, in the order that matters.
The COA must clearly identify the compound and the production lot. The lot number on the COA must match the lot number printed on your product label.
Look for HPLC and mass spectrometry as the primary methods. These are the industry standard for peptide purity and identity verification.
Reported as a percentage. Our threshold is 99% or higher. The exact figure for the batch you receive will appear on the matching COA.
The independent lab name, the test date, and the analyst signature establish that the result is third-party verified, not self-reported.
A COA is only as credible as the chain that produced it. Here is the chain we run for every batch.
Compound produced at a vetted research-grade facility.
Representative sample sent to an independent third-party laboratory.
Lab runs purity and identity testing using industry-standard analytical methods.
Certificate of Analysis published with method, result, lot number, and lab signature.
Batch approved for catalog only after meeting the 99% purity threshold.
The matching COA travels with every order in the box and remains in our library.
Locate the lot number printed on the side of your product label. Search that lot number in the table above, or visit the matching entry in this library. The lot number on the label and the lot number on the COA will be identical.
Yes. We retain COAs for all shipped batches. Use the contact page with the COA topic selected and include the product name and lot number. A copy will be emailed within one business day.
Independent third-party laboratories that specialize in peptide analysis. The labs are not owned by us, do not share staff with us, and are not paid based on results. The lab name and signature appear on every COA.
It does not enter the catalog. Batches that test below 99% are rejected at the verification stage and never approved for sale. There is no “good enough” tier. The threshold is non-negotiable.
