Quality & Testing

We don’t grade our own work.

Every lot is tested by an independent laboratory before it reaches us, then tested again by us when it arrives. The number on the certificate is the number in the vial.

  1. 01

    Independent testing, first

    Before a lot ever reaches us, it goes to a third-party laboratory with no stake in the result. High-performance liquid chromatography establishes purity; mass spectrometry confirms the molecule is what the label says it is.

  2. 02

    Our own check, on arrival

    When the lot lands, we test it again ourselves. Two independent results have to agree before a compound earns a place in the catalog. A batch that fails either test goes no further. The industry accepts 95%. We reject it.

  3. 03

    Certificate, matched to your vial

    Each lot carries its own certificate, traceable by lot number to the exact vial in your hand — not a representative sample, not a batch average. It is held in your account for as long as you need it.

The Methods

What the tests actually measure.

HPLC — purity
Separates the sample into its components and measures the proportion each represents. This is where the 99%+ figure comes from.
Mass spectrometry — identity
Measures molecular mass to confirm the compound is the one named on the label. Purity means nothing if the molecule is wrong.
Lot traceability
Every vial carries a lot number printed on the label and recorded against its certificate, so any vial can be traced back to its analysis.

Through precision and reverence for complexity, we support the exploration of life’s deeper patterns.
