We grade vendors in public, so we hold ourselves to a public standard too. If we get a fact wrong, we want to fix it fast. And if a vendor disagrees with what we published, they get a fair, free chance to respond.
This page explains exactly how that works.
Our promise
Every grade we publish is our editorial opinion, grounded in disclosed, dated facts. Facts can be wrong, go stale, or be missed. When that happens, we correct the record openly and note what changed.
We never quietly delete or rewrite a grade to make a problem disappear. Corrections are logged, and disputed grades stay visible while we look into them.
Money never changes any of this. The same rubric applies to paying and non-paying vendors, and affiliate links and sponsored placements never affect a grade, a ranking, or how we handle a correction or reply.
Reporting a factual error
Anyone can flag a factual error in a review, a score, or a piece of evidence we have cited. You do not need to be the vendor.
Send us:
- The exact page or vendor, and the specific claim you believe is wrong.
- What you think the correct fact is.
- Any evidence you can share (a link, a document, a lab report, a dated screenshot).
Email corrections@checkthevendor.com with “Correction” in the subject line.
Our review timeline: we aim to acknowledge every report within about 5 business days and tell you one of three things: we have corrected it, we need more information, or we have reviewed it and are leaving the published fact as-is, with our reasoning.
If a correction changes a measured input, we re-run the affected criterion and recalculate the composite score. Where that moves the letter grade, we say so and date the change.
Vendor right of reply
If you are a vendor we have graded, you have a free, standing right to reply. There is no charge, and using it does not move your grade up or down on its own. We assess what you send on the same rubric we apply to everyone, whether or not you have any commercial relationship with us.
1. Verify you represent the vendor
To protect vendors from impersonation, we confirm identity before acting on a submission. We ask you to contact us from a domain email matching the vendor’s listed website, or to post a short verification code we supply to an official channel you control (for example, your site or a verified business account). We will tell you which method applies and confirm once you are verified.
2. Submit your response or new evidence
Once verified, you can send us either or both of:
- A written response. Tell us what you believe is inaccurate or missing. We will read it in full. Where it identifies a genuine factual error, we correct it. Where it is a difference of opinion, we may publish a short, fair summary of your position alongside the grade.
- A current, verifiable COA. If our grade reflects missing or stale lab data, the most direct fix is an independent third-party Certificate of Analysis we can verify. Send the full COA, the lab that issued it, and the lot or batch it covers.
Email vendors@checkthevendor.com to start.
How a disputed grade is handled
When a vendor formally disputes a grade and the dispute is under active review, we do not take the review down.
Instead, the grade stays live with a “Disputed — under review” label, so readers see both the current grade and the fact that the vendor has challenged it. Removing reviews on request would let the record be edited by whoever complains loudest, and that is the opposite of what we are for.
When the review concludes, we remove the label and either update the grade with a dated note explaining what changed, or keep it as published with our reasoning. Either way, the outcome is on the record.
How we verify a submitted COA
A COA only helps your grade if it is genuine and checkable. When you send one, we:
- Confirm the issuing laboratory is a genuine independent lab and contact it (or use its published verification system) to confirm the document and its result.
- Check that the named lot or batch matches what the lab tested and what you are selling.
- Check the dates against our re-review cadence — COA and purity inputs are refreshed per new batch, otherwise every 6 months, with a test-buy refresh annually.
A verified independent COA can lift a grade that was previously limited by missing lab data. The integrity gate still applies: a vendor with no independent third-party COA cannot score above a D.
Submissions we cannot accept
This process runs on trust, so we take abuse of it seriously.
Our integrity gate is binding: a vendor we find to have published fabricated or reused COAs, or fake reviews, is capped at F and flagged. If that occurs in the course of a reply or dispute, we apply the same gate. We will state the verifiable observation — what we found and how we checked it — and let readers draw their own conclusions.
What this process can and cannot change
We rate vendor quality only — third-party lab testing and COA verification, measured purity, transparency and disclosure, reputation and customer service, pricing and value, shipping and fulfilment, payment and checkout trust, and website and operational trust signals.
This process cannot be used to dispute anything outside that scope. We do not assess, and will not debate, the safety, effects, legality, or suitability of any peptide for any purpose, and we do not provide medical, dosing, or health advice. Where a vendor states its own usage or labelling position, we may report that as a fact about the vendor; we do not adopt it as our own.
