COA Library: Research Peptide Certificates of Analysis

How the COA Table Works

The table below has one row for each product and vial size, with columns for the batch, the HPLC purity result and a link to the full report. We add each certificate as the lot is tested and update the row when stock is replaced, so the batch shown may be newer or older than the vial you hold. A row reading "Awaiting upload" means the current PDF has not been posted yet, not that the lot went untested.

Finding the Lot Number on Your Vial

1. Look at the label on the vial, capsule bottle or nasal spray for the printed lot or batch number.
2. Find the product and size in the table and open the report.
3. Compare the lot number on the report with your label, character by character. They should match exactly.

If your lot is not listed, or a report you need shows as awaiting upload, email our support team with the product name, size and lot number and we will send the matching certificate.

What the Certificates Report

Identity testing compares the measured mass of the compound with the expected molecular weight for its sequence. Purity testing by HPLC gives the share of the sample made up of the target compound. Blend vials such as KLOW, GLOW and the peptide blends range should report each component. For a walk-through of chromatograms, charge states and red flags, read our guide on how to read a COA, or browse every lab-tested compound in the peptide shop. Certificates describe the material as tested and do not imply suitability for anything other than laboratory research. Products are not for human or veterinary use.

Buy Online After You Check the Certificate

This library exists so you can read the evidence before you buy. Find the lot, confirm identity and purity, then shop that product online from the peptide shop or browse the lab-tested peptides range. Researchers who would rather buy peptides near me than online can still check every certificate here first.
