What a COA is
A certificate of analysis, or COA, is a report from an independent testing lab showing what that lab found when it tested a specific batch of product. For a THC beverage, the most important line is potency: how much Delta-9 THC was actually measured in the sample compared with what's on the label.
Where NICE's testing comes from
NICE has certificates on file from independent labs, including ProVerde (dated December 2025) and Trichome Analytical (dated May 2026). We publish these so you can check a batch's measured potency yourself rather than taking the printed 5 mg figure on faith.
What 'batch variation' means on a COA
Across the six independent lab certificates NICE currently publishes, measured Delta-9 THC has ranged from 4.54 mg to 5.20 mg per can, even though 5 mg is the formulation target for every batch. That range reflects the certificates NICE currently has on file — not a general rule for the category — which is exactly why checking the certificate for your batch matters more than assuming a single printed number.
What a COA does and doesn't tell you
A COA tells you what was measured in the specific batch it covers, by the lab that ran the test, on the date it was run. It's not a claim that every single batch a brand has ever produced was screened for every possible contaminant — read the report for what it actually covers rather than assuming it certifies the entire product line forever.
How to actually check one
Match the batch number on your can (or the closest available date) to the corresponding report, check the reported Delta-9 THC amount against the label claim, and note the testing lab and date. If a brand can't produce a lab report at all, that's a much bigger concern than normal batch-to-batch variation.
