How we verify vendors
Every brand listed above has gone through our six-step verification:
- Business entity verification (EIN, registered address, state license where applicable)
- Lab-of-record disclosure and contact confirmation
- Sample-batch independent testing through our partner lab network
- COA template review for completeness (identity, purity, endotoxin, counterion)
- Storage and handling chain-of-custody audit
- Customer-service responsiveness benchmark (4-hour SLA)
