Database
Every vendor on file
Sorted by cost per gram of mitragynine where we have both a price and a published assay. Vendors without either appear at the end, marked as such, because an absent certificate is itself a finding.
How this database works
How do you rank vendors?
By cost per gram of mitragynine, computed from the vendor's own published certificates and their current kilo price. Not by commission, not by sticker price. Vendors with no published assay cannot be ranked and are listed separately, marked as such.
Why not just compare price per kilo?
Because tested mitragynine content in commercially available kratom ranges from 0.11% to 2.02%. A kilo at one end contains roughly eighteen times the alkaloid of a kilo at the other, at broadly similar prices. Comparing kilo prices tells you almost nothing about what you are actually buying.
Where do your numbers come from?
We transcribe them from certificates the vendors publish themselves, recording the batch identifier, test date and laboratory alongside every figure. Each value on a vendor page links to the document it came from and shows the date we read it. We do not take figures from other review sites.
Do you get paid by vendors?
We earn commission on some outbound links, disclosed at the link itself. No vendor pays for placement, ranking or a score, no vendor reviews a page before it publishes, and the ranking is a calculation rather than an opinion, so there is nothing for a commission to move.
How often is this updated?
Prices and certificates are re-checked on a rolling basis and every page carries the date each field was last verified plus a visible history of what changed. There are currently 0 vendors on file.
