Aggregate dataset

Purity across every documented lot

Most suppliers publish a purity figure. This is the whole dataset behind ours: every lot we have released, what the independent laboratory measured, which laboratory measured it, and when. Summarised at the top, itemised below, and open to anyone.

By compound

Every compound, every lot

Sortable. The range column is what a single average cannot tell you: how consistent a compound has been across releases.

Provenance

Who did the testing

Analysis is not done in-house. Each certificate names the laboratory that ran it.

How to read this honestly. A Certificate of Analysis reports analytical conformance for one lot: identity, purity, appearance and net content. It is not a safety assessment, not an efficacy result, and not a statement about any other lot. Figures here are the measured values from those certificates, aggregated without adjustment. Where a certificate states a purity as a threshold rather than a number, it is counted in the lot totals but excluded from averages.
