How We Evaluate Vendors
Our scoring methodology is built on verifiable, objective quality metrics
COA Verification
We verify that vendors provide batch-specific, third-party Certificates of Analysis with real HPLC and Mass Spectrometry data for every product in their catalog.
Purity Scoring
We analyze reported HPLC purity percentages across each vendor's product catalog, looking for consistent 98%+ purity with proper documentation and testing methodology.
Price Analysis
We compare pricing across standardized quantities and evaluate value relative to verified quality. The cheapest option is rarely the best when purity varies between vendors.
Community Feedback
We aggregate feedback from the research community across forums, review platforms, and direct researcher reports to identify consistent patterns in vendor quality and service.
