A Certificate of Analysis is the lab’s report on one specific batch. Here is what to actually look at:

• Total THCa / Total THC — potency. Check the delta-9 THC figure specifically: ours stays under 0.3% by dry weight.
• Batch / lot number — must match the code printed on your package.
• Test date — should be recent, and after the harvest date.
• Pesticides, heavy metals, residual solvents, microbials — every one should read PASS.
• Lab name and accreditation — an ISO 17025 accredited lab, not an in-house bench.
