A Certificate of Analysis is the most important document in this industry — and most shoppers never read one. Here’s how, in four steps.
Step 1: Match the batch code
Every authentic COA lists a batch number. Match it to the code printed on your package — if the seller can’t connect the two, the document is decorative. All current Zana batches are published on our Lab Reports page.
Step 2: Check the potency panel
The panel should list alkaloid content in mg or % and match the label claim. Large discrepancies between label and lab mean the label is marketing, not information.
Step 3: Scan the safety panels
- Heavy metals (lead, arsenic, cadmium, mercury)
- Microbial counts (yeast, mold, bacteria)
- Pesticide residue screening
- Solvent residues for extracted products
Step 4: Check the lab itself
Reputable COAs come from ISO-accredited independent labs — not the manufacturer’s own bench. ‘Pass’ results without lab letterhead are a red flag, always.
