Peptide material varies from lot to lot. A certificate from a previous batch, or from a manufacturer you never see, does not tell you what is in the vials you are about to receive. Testing each wholesale lot after it arrives, and before it ships, is how the report and the product stay tied together.
It also changes who carries the risk. If a lot fails, it never reaches you. That cost stays with us, which is exactly where it should sit for a supplier asking you to trust its documentation.
Wholesale samples are tested for purity and identity at independent labs in College Station, TX, using the same kind of analytical methods reported across our COA Library, such as HPLC for purity and mass spectrometry for identity. To understand what those reports show, see our guides on HPLC vs LC-MS and peptide purity percentages.
Because we are local to the labs, samples are hand-delivered and followed through testing personally rather than mailed. Results usually come back in two to three days.
For wholesale buyers, the Certificate of Analysis is issued in the buyer's company name, not ours. It is yours to publish, to hand to your own customers, or to keep on file. Peptide brands and resellers often find this is the part that matters most; read more on our page for peptide brands and resellers.
