Methodology:Purity averages exclude values outside [50%, 100%] to filter unit misreads. "Vendors tested" counts distinct vendor IDs across all in-scope, non-withdrawn, extracted COAs. Endotoxin/sterility coverage denominators are all in-scope COAs (not filtered to parenteral form).
Data updates hourly. All figures are computed from lab-uploaded COAs; Disclosed does not perform independent testing.
Based on 2 Certificates of Analysis in the Disclosed corpus, P21 has an average HPLC purity of 99.1% (±0.6% std dev). This figure spans 2 vendors tested across 1 independent lab. Purity is measured by high-performance liquid chromatography (HPLC); values outside 50–100% are excluded as unit misreads.
1 distinct testing lab has produced COAs for P21 in the Disclosed database, covering 2 total tests across 2 vendors.
50% of P21 COAs in the Disclosed corpus include endotoxin test results (USP <85>), and 0% include sterility results (USP <71>). Endotoxin and sterility testing matter for injectable-grade peptides — their absence in a COA does not indicate failure, but absence is common in HPLC-only testing workflows.
