The Atlas standard

How a lot gets released

1. Supplier lot received. We record the supplier COA, synthesis date and customs documentation, and quarantine the lot.
2. Independent testing. Samples go to a third-party lab for RP-HPLC purity (chromatogram and wavelength reported) and mass-spec identity (observed vs theoretical mass). Where tested, endotoxin and net content are added.
3. Release decision. Lots below 98% purity, or with an identity mismatch, are rejected and never listed.
4. Publication. The COA is posted to the product page and COA library, and the lot number is printed on every vial.
5. Retained samples. We keep samples from every lot for re-testing if a researcher or regulator asks.
