Affiliate disclosure

Peptideworth is reader-funded through affiliate relationships. Some outbound links on this site are affiliate or referral links. If you follow one and start a program or buy a product, the company may pay us a commission for the referral.

You pay the same price you would have paid arriving any other way. The commission comes out of the company’s marketing budget, not out of your pocket, and there is no version of a link here that costs you more than the same link found elsewhere. That revenue is what keeps the research free to read and free of advertising.

Peptideworth’s subject includes compounds that are not approved for any use, and some that are sold only for laboratory use. Those pages are exactly where a commercial link would do the most damage, so they do not have one.

• No affiliate link. Pages about unapproved compounds carry no monetized outbound link of any kind.
• No vendor named. We do not name, link, rank, or hint at sellers of research-use-only material, and we will not tell you where to obtain it.
• No sourcing guidance. Not in prose, not in an FAQ, not in a “where people usually get it” aside.

The reasoning is simple enough to hold to. We cover these compounds because people are already searching for them and the pages answering those searches are mostly written by sellers; an accurate account of the evidence is a better result than a sales pitch. That argument only works if the accurate account is not itself a sales pitch. Where a page concludes that no human trial exists, there is nothing next to it to buy.

Stated as flatly as we can put it, commission never determines:

• whether a compound is covered at all, or which compounds get a page;
• how the evidence is characterized — the evidence tier, the trial numbers reported, or how confidently a finding is described;
• whether the “catch” is softened. The uncomfortable part of a compound page is a required field, and a commercial relationship is not a reason to shorten it;
• whether unflattering findings are published. They stay in, including about a company that pays us.

No company sees a page before it is published. Nobody reviews, approves, edits, or previews our copy, and nobody has been offered the chance to. If a partner ever asked us to change an assessment, the answer would be no and the request itself would be worth publishing.

What the funding does move is placement — where a commercial link can appear on a page that has one. We would rather print that than leave you to infer it. The assessment it sits next to is produced by the method in our editorial policy, which has no input for who pays us.

You should not have to take our word for which links are commercial. Outbound provider links route through a /go/ path on this domain, which records that a click happened, tags the destination with a campaign identifying this site, and forwards you. Where the relationship is actually paid, the link carries the sponsored attribute that search engines read as a declared commercial link.

That attribute is set from whether we are genuinely paid for that click and from nothing else — it is not a styling flag, and declaring a paid relationship that does not exist would be a false statement to you and to a search engine alike. Links to trials, journals, labels, and regulator databases are never affiliate links; they are the evidence, and monetizing a citation is not something we do.

There are no display ads on this site, no sponsored articles, no paid guest posts, no native advertising, and no sold links inside editorial text. Nobody can buy a mention, a position, or a favorable sentence. We do not take payment to review a product, and we do not accept free product in exchange for coverage — we do not test products at all.

We also do not run advertising personalization or sell data about you. What we know about our readers is aggregate analytics, and only if you accepted it; the mechanics are in the privacy policy.

Commercial arrangements start and end. That is why this page describes how we work rather than publishing a partner count, a ranking rule with a number in it, or a list that would be out of date the week after it shipped. A specific number in a disclosure expires silently, in copy nobody re-reads, and a disclosure that has quietly become false is worse than a general one that stays true.

Every outbound provider link, paid or not, is built the same way and looks the same to you, so a relationship beginning or ending never silently changes what a page looks like. What changes is the link attribute, which is set from the truth.

This page is our disclosure under the FTC’s guidance on endorsements and affiliate relationships, and the short disclosure line appears alongside the content itself rather than only here. Commission never changes the price you pay, and nothing on this page limits anything in our medical disclaimer: a link is not a recommendation to take anything.

If something here reads as unclear, or you think a link is misrepresented, write to research@peptideworth.com and we will fix the page. That process is set out in our corrections policy.
