How we list suppliers

What a listing means

We list companies that sell peptides so you can see who they are in one place. That is all a listing means.

We have not tested any product from any company on this page. We have not visited their facilities, audited their certificates of analysis, or verified their purity claims. A listing is not a recommendation, an endorsement, or a statement that a company is trustworthy.

If you are deciding whether to buy something, this page tells you who sells it. It does not tell you whether you should.

How companies get on this page

We add companies we find that sell peptides listed on this site and that publish a working website with contact information and stated product details.

These are minimum requirements, not a review. They establish that a company exists and is reachable. They do not establish that it is reputable or that its products are what it says they are.

We do not charge for inclusion and companies cannot apply to be added.

How they are ordered

We do not rank suppliers. Listings appear in alphabetical order.

Order does not reflect quality, price, or our opinion.

Money

No company has paid to appear on this page, and no listing position has ever been sold. We do not earn commission when you click through to a supplier.

We plan to sell advertising and sponsorships in the future. When that happens:

• Paid placements will be labeled "Sponsored" on the placement itself, not only in this policy.
• Paying us will never change whether a company is listed, where it appears in a list, or what we write about it.
• Sponsors get no advance notice of, and no influence over, anything on this site.
• Paying us does not protect a listing. Every removal reason below applies to sponsors exactly as it applies to everyone else.

When you click a supplier link, we record that a click happened so we can see which listings get used. We store a one-way hash of your IP address, not the address itself, and we do not sell or share this.

Research suppliers and clinical providers are different

We separate companies that sell research chemicals from licensed clinical providers such as telehealth services and compounding pharmacies. These are not interchangeable. Research suppliers sell material that is not intended for human use and is not dispensed under a prescription. We label which is which, and that label describes how a company presents itself, not a license we have verified.

When we remove a company

We remove a listing when we learn of any of the following:

• An FDA warning letter, import alert, or enforcement action against the company
• Credible third-party testing showing contamination, misidentified product, or purity substantially below what was claimed
• The company marketing research-use material as a treatment, or making claims about curing or treating disease
• The company selling to consumers as though for personal use while labeling material research-only
• A state pharmacy board action against a listed clinical provider
• The company ceasing to operate, or its site going dark

We remove first and correspond afterward. We are not a court and we do not owe a listing to anyone.

When we remove a company, we say so: removals are noted on this page with the date and the reason category. We do not quietly delete listings.

Telling us about a problem

If you know something we should know about a company here — a test result, an enforcement action, a bad experience — email corrections@peptidesearch.org.

We read everything sent to that address. We cannot promise to act on every report, and we will not publish accusations we cannot substantiate.

Corrections

If anything on this page is wrong, tell us at the same address and we will fix it and note the change.
