Independence rules

A review site is only useful if you can trust it. These are the rules we hold ourselves to. They are not aspirations; they are commitments, and if we ever break one we will say so on this page.

The rules

• Vendors cannot pay us for anything that touches a score. Not for testing, not for placement, not for a badge, not to remove or soften a review.
• Affiliate status never affects a score. We publish failed results for vendors we earn commissions from, exactly as we do for vendors we don’t.
• Every vendor page says whether we earn a commission from that vendor. You will never have to dig for it.
• We never use free samples for scoring. Everything we test, we bought at retail, anonymously.
• Labs are paid suppliers, not sponsors. We pay our testing lab like any other customer. Any volume discount we receive is disclosed here.
• Samples are coded. The lab does not know which vendor a sample comes from.
• Negative reviews are never removed for being negative. Reviews are removed only for being fake, abusive, or off-topic, and every removal is logged.
• Corrections are public. Every change to a published result is recorded, with the date, on the corrections log.
• We do not give health or dosing advice. Not on the site, not in videos, not in reviews we feature.

Who we are not connected to

KratomSource does not own, operate, or hold any stake in a kratom vendor, manufacturer, or importer. No vendor, manufacturer or importer holds any stake in KratomSource. If that ever changes, it will be disclosed here first.

Historical note

Until November 2026 this site accepted paid placement from vendors. We say so here because a reader comparing an old review to a new one deserves to know the rules changed. Every vendor page published since then follows the rules above, and any review from the old model has been retired and replaced.

Lab relationship

Our primary testing lab is Murray-Brown Laboratories, and it is named on every lab report. We are a paying customer on standard commercial terms. If we ever agree a volume discount or partnership with the lab, the terms will be disclosed here. Failed results are confirmed at a second, independent accredited lab before publication.

If you think we’ve broken a rule

Tell us. Use the contact page, and we will reply publicly on the corrections log if the complaint has merit.

Frequently asked questions

Can a vendor pay to improve its score?

No. Not for testing, placement, a badge, or to soften a review. Scores come from the certificate of analysis and the published formula.

Do affiliate links affect reviews?

No. We publish failed results for vendors we earn commissions from exactly as we do for vendors we do not, and every vendor page says whether a commission is earned.

Did KratomSource used to take paid placement?

Yes, until November 2026, and the old footer said so. Those arrangements have ended and every review from that model has been retired and replaced.
