PeptideScouter is free to use because some of the outbound links on this site are affiliate links. When you click through and make a purchase, we may earn a commission from the vendor — usually at no extra cost to you, and often paired with a discount code that drops the price below what's listed on the vendor's homepage.
An affiliate link is a regular link that includes a tracking parameter so the vendor knows the visit came from us. If you buy something within the vendor's tracking window, the vendor pays us a small percentage of the sale. You're not charged anything extra.
The price you see is the vendor's actual listed price, in USD per milligram. Sorting is mechanical: lowest $/mg first. We do not accept payment for placement, do not hide non-affiliate vendors, and do not adjust the price math to favor partners. A vendor with better pricing will always rank above a vendor that pays us a commission.
Where a discount code is available, we surface it as an orange tag in the listings. The discounted price is reflected in the comparison, so the math stays honest.
This page exists to satisfy the U.S. Federal Trade Commission's guidance on endorsements and testimonials (16 CFR Part 255). Our goal is the same as the FTC's: you should know when a link can pay us, so you can weigh that information when deciding what to do with it.
If something on the site looks like it favors a paying vendor over a better-priced one, please tell us — that would be a bug, and we want to fix it. Email hello@peptidescouter.com.
