Are Chainwell peptides independently tested?

Independent third-party testing has started. Each lab report is published on its product page under Quality & testing, and the compounds on this page already have one.

What does a certificate of analysis include?

The lot number, the compound identity, an HPLC purity result with its chromatogram, and a mass spectrometry result that confirms the molecular mass.

Can these products be used outside the lab?

No. Every product is sold strictly for in-vitro laboratory research and is not for human or veterinary use.

Q: What about compounds without a lab report?

We don't show a purity figure for them until the supplier's specification is confirmed. Reports are added as each lot is tested.

These compounds have an independent third-party lab report for the current lot, published on each product page under Quality & testing. More are added as each report comes in.

What a lab report shows

A certificate of analysis ties one lot to two checks: an HPLC chromatogram for purity, and a mass spectrum that confirms the molecule is the right one. For everything else in the catalog, no purity figure is shown until the supplier's specification is confirmed.
