About this collectionScope, measurement and findings
Collection scope
110,269 COA report entries are published across the archive. The 224 evidence profiles on this page include 89,031 stored report entries with measured results. Entries are not unique certificates or batches; one certificate may contribute multiple entries. Other reports may cover separate tests, unnamed compounds or compounds with too little evidence for a profile.
Profiles preserve source labels, including blends and unresolved labels. Similar names do not establish that samples or batches are the same.
Reading the measures
Purity is the median of included reported purity values, including zero. Reported 0% purity counts entries recording a numeric zero; read the original report to understand the finding. It is not a count of verified identity failures or unique batches.
The amount measure compares a tested amount with an explicit label amount; results from −10% through +10% are within range. For example, a sample labeled 10 mg falls within range from 9 mg through 11 mg. Batch-claim comparisons, including Finnrick comparisons, use a different reference and are excluded.
“Based on” is the number of results used for that measure. Compare it with the row’s report-entry total to see how much of the profile contributes. Missing fields or an incompatible measurement basis can exclude an entry; exclusion does not prove a test was never performed. Small samples are marked explicitly.
