Mad Honey Lab Reports: Open Grayanotoxin Dataset

Mad honey’s active compound, grayanotoxin, varies from batch to batch — which is why a published, third-party lab report is the single most important thing to check before buying or dosing. Almost no one in this niche publishes theirs. We do, batch by batch, as an open dataset you can cite and link.

Every figure below comes from an independent laboratory’s Certificate of Analysis (COA), measured by LC-MS/MS. The full signed PDF is linked for each batch.

Values are for the tested batch only; grayanotoxin content varies naturally between harvests. We publish the measured figure per batch rather than a fixed potency claim — which is exactly why you should dose against a known level, not a guess. New batches are added here as they’re tested.

How to read a mad honey lab report

A genuine COA names the accredited laboratory, carries a certificate number and date, states the testing method (LC-MS/MS is the standard for grayanotoxins), and gives the concentration in µg/kg. If a “lab report” is missing any of those, treat it as marketing, not evidence. Our how to identify authentic mad honey guide covers the rest of the checklist, and the grayanotoxin explainer covers what the numbers mean for effect and safety.

Why we publish this openly

Grayanotoxin is a genuine natural toxin (FDA), documented in peer-reviewed medical literature. Knowing the measured level is both proof a honey is authentic and the basis for dosing it safely. Publishing the raw numbers — openly, per batch — is how a seller earns trust instead of asking for it.
