Certificate of Analysis
Every batch is verified by an independent lab — not our own bench. Enter the lot number from your vial to request its report.
Look up a lot
Reports are sent by email, usually the same business day. You do not need to have bought from us to request one.
Finding your lot number
The lot number is printed on the vial label beneath the product name, and appears on the packing slip in your parcel. It identifies the exact batch your vial was filled from — two vials of the same peptide bought months apart will carry different lots and different reports.
What the report covers
- HPLC — high-performance liquid chromatography, establishing purity as a percentage of total peak area.
- Mass spectrometry — confirming the molecular weight matches the sequence claimed, so the vial holds the peptide on the label.
- Appearance, and net peptide content for the lot.
- The testing laboratory and date, so the result is attributable and you can see how recent it is.
Read the purity figure alongside the identity confirmation. A high purity number means little on its own if mass spec has not confirmed that the substance is the one you ordered.
If a report does not match
If a batch fails to match its published Certificate of Analysis, we replace it or refund it in full. See Shipping & Returns for how to raise that.
Research use
A Certificate of Analysis reports what a batch contains. It is not a safety assessment, and it does not qualify any product for human or veterinary use. All products are supplied for laboratory research only.
