Evidence first

Evidence, not promises.

High-purity chemical sequences, characterized and verifiable. Every batch ships with a Certificate of Analysis, purity by HPLC, batch provenance, full receipts. Research use only.

We don't ask for trust. We publish the method.

Synthesis, then high-performance liquid chromatography for purity and mass spec for identity. The released lot record identifies its method and scope. The chromatogram is on the COA. Read it before you read us.

  • HPLC: Purity by high-performance liquid chromatography, with the chromatogram on the certificate.
  • Mass spec: Identity confirmed by mass spectrometry, the chemical sequence is what the label says.
  • Released record: Read the lot identifier, method, and scope in the verifier.
