We get paid when
you buy. Here is
exactly how.

Vendors listed on this site pay us a commission when you buy through our links. It costs you nothing extra, and it does not change where they appear. Rows are ordered by price per milligram, which is arithmetic on the vendor’s own published price and vial size. No vendor can pay to rank higher, to be flagged, or to have a competitor removed. Anything that is paid placement is labeled sponsored where it appears.

Outbound vendor links on this site carry a tracking parameter — a referral code, an affiliate ID, or a campaign tag. When you follow one and complete a purchase, the vendor’s affiliate system attributes that order to us and pays us a percentage of it or a fixed fee. Attribution usually runs on a cookie the vendor sets, with a window measured in days or weeks depending on their programme.

You pay the vendor’s normal price. The commission comes out of the vendor’s margin, not your total, and following our link never raises what you are charged. Where a vendor supplies a discount code, using it lowers your price — those are published in the ledger and on the vendor row, not held back.

Outbound affiliate links are marked up with rel="sponsored nofollow" so the commercial relationship is visible in the markup itself, not only in this page’s prose.

We participate in the affiliate programmes of vendors indexed on this site, including Aminoclub, BioInfinity and Peptime. Programmes are added and dropped over time; the presence of a tracking parameter on a vendor link is the reliable indicator that a commercial relationship exists for that link.

Some vendors we index pay us nothing. They are listed on identical terms, with identical fields, and are eligible for the same flags. A vendor with no affiliate programme can and does outrank vendors that pay us, whenever their price per milligram is lower.

The reason the line sits there is structural rather than virtuous: a price index whose order can be bought is not an index, and would be worth nothing to you and therefore nothing to us. The ranking is the product.

To be straightforward about it: we earn more when you buy, so we have an interest in you clicking through. That interest is real and we will not pretend otherwise. What it does not give us is an interest in which vendor you buy from, since most of them pay us at broadly similar rates — which is what makes ordering the rows honestly the cheapest option available to us.

What we have no incentive at all to do is tell you to buy something. We publish no dosing guidance, no protocols, no human-use instructions and no therapeutic claims. Every compound indexed here is research-use-only material; our terms of use set out the scope of that.

A vendor appearing on this site is not a recommendation of that vendor, an endorsement of their products, or a warranty of anything they publish. It means we found a listing with a price and a stated peptide content and put it on the same axis as the others.

We do not assay products, audit laboratories, or verify that material in a vial matches the certificate attached to it. Your own due diligence on any vendor — their documents, terms, returns, and legal standing in your jurisdiction — remains yours to do.

If you want to know whether a specific link is commissioned, whether a specific placement was paid for, or how a specific row came to be ranked where it is, ask and we will tell you.

Use the contact page. Vendors enquiring about affiliate or sponsorship terms should use the same address, and will get the same answer as everyone else about what is and is not for sale.
