The Core Promise
Ratings on Peptide Source Review are produced by a published algorithm (see How We Rate) that scores every vendor against the same five factors using the same weights, the same anchor scale, and the same safety gate.
- No vendor can pay to change their score. Period.
- The formula is public. If you disagree with how a score was reached, you can run the numbers yourself.
- Editor's notes describe public evidence. They are not a paid pitch and not written by the vendor.
- The methodology page logs changes. If we re-tune the formula, every vendor is re-scored under the new rules — not just the ones we like.
How Sponsorships Work
We may accept paid sponsorship from vendors. Sponsorship buys visibility only. A sponsor might get a highlighted card, a featured banner, or a more prominent placement on the page — but their algorithmic rating is calculated and displayed exactly the same way as every other vendor's.
- Every sponsored placement carries a clear "Sponsored" badge. You will always know when you are looking at a paid placement.
- Sponsorship does not change the formula, the score, the rank, or the gate.
- A sponsored vendor with a low score still shows their low score. We will not bury a "Caution" badge or a low star rating because someone paid for visibility.
- Sponsors do not get advance review of editor's notes. They see them when you do.
How Affiliate Links Work
Some "Visit site" links on this site may be affiliate links — meaning we earn a small commission if you click through and make a purchase. This helps keep the site running. Affiliate participation never affects the score.
- Any vendor we have an affiliate relationship with is listed publicly in the section below.
- Affiliate "Visit site" buttons are clearly labeled with an "Affiliate link" tag, so you see the disclosure at the moment of decision — not buried in a footer.
- We do not boost an affiliate vendor's score. Same algorithm, same weights, same gate.
- We do not soften criticism for affiliate vendors. If we find concerning evidence, it goes in the notes regardless of commission potential.
Current Sponsors
As of May 17, 2026, we have no paid sponsors.
When that changes, every active sponsor will be listed here with the date the sponsorship began. If a sponsorship ends, it stays listed with the end date so you can see the full history.
Affiliate Partnerships
As of May 17, 2026, we have no affiliate partnerships.
When we do, every affiliate relationship will be listed here. The vendor's "Visit site" button on the main list will also carry an inline "Affiliate link" label so the disclosure travels with the click.
Our Commitments
- We will not adjust a vendor's score because they paid us, are paying us, or might pay us.
- We will not delay, soften, or hide negative findings about a sponsor or affiliate.
- If we discover we were wrong about a vendor, we update publicly and note the change date in the vendor's notes.
- If we ever change these rules, this page changes too — and the "as of" date at the top of this section updates.
- If a sponsor ever asks us to remove or alter a finding because of their sponsorship, we will end the sponsorship and note it publicly here.
If you spot a vendor placement, badge, or note that looks like it violates any of the above, please tell us using the Submit page.
