A practical vendor scorecard weighs documentation, specification clarity, and response quality ahead of slogan-heavy pages.
Catalog structure: Are research categories and specification tables easy to audit?
COA access: Can you retrieve lot records for the SKUs you actually buy?
Third-party testing: Are Janoshik or equivalent reports available on priority lots?
Quote discipline: Do replies lock Cat No., mg strength, and shipping terms?
Packing: Is international cushioning and cold-aware packing described for peptide vials?
Support: Can the team answer documentation questions with concrete references?
RUO language: Is research-use-only scope explicit on pages and invoices?
Continuity: Will they discuss prior lots when you reorder for multi-phase studies?
