How to read these figures

Median purityMedian reported %purity across this compound's published certificates. The bar rescales the 80-100% band, so 95% and 99% read clearly apart. ≥98 ≥95 ≥90 <90.

Dose passShare of certs whose tested quantity lands within ±10% of the labeled dose. ≥90 ≥70 <70.

Dose splitOf the certs carrying a tested-vs-label dose, the share overdosed (≥ +7% over the labeled dose) and underdosed (≤ −7% under). The remainder land close to label.

Labs / VendorsDistinct independent labs, and distinct vendors, represented in the corpus.

Zero-purityCertificates where the lab found 0% of the labeled compound, a direct mislabel or fraud signal. Always open the individual cert.
