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 "Vendors tested" counts distinct vendor IDs across all in-scope, non-withdrawn, extracted COAs.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 215 Certificates of Analysis in the Disclosed corpus, GHK-Cu has an average HPLC purity of 99.6% (±1.3% std dev). This figure spans 52 vendors tested across 17 independent labs. Purity is measured by high-performance liquid chromatography (HPLC); values outside 50–100% are excluded as unit misreads.
17 distinct testing labs have produced COAs for GHK-Cu in the Disclosed database, covering 215 total tests across 52 vendors. 1 of those lab has a verified Disclosed partner account, meaning their COAs are uploaded directly by the lab.
43% of GHK-Cu COAs in the Disclosed corpus include endotoxin test results (USP <85>), and 23% 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.
Verified labs with COAs for GHK-Cu in the Disclosed corpus include: ILS Labs (grade B, 15 COAs). These grades reflect Disclosed's credibility scoring of each lab's full COA corpus — purity distribution, safety panel breadth, and verification engagement.
