Working with suppliers.
How suppliers end up on PepLookup, how affiliate relationships work, and the line we hold between the two. We currently track 83 suppliers.
Commission never buys a ranking
Suppliers are ordered by the numbers alone: price, cost per mg, stock and the filters you choose. Whether we earn a commission from a supplier has no bearing on where they appear, and there is no paid placement anywhere on this site.
Listing is free and does not require a deal
Most suppliers on PepLookup have no relationship with us at all. We list them because they publish prices we can compare. A supplier does not have to pay, partner or ask to be included.
You never pay more
An affiliate link costs you nothing extra. The price you pay is the supplier’s own price, and any commission comes out of their margin, not your order.
For suppliers.
If you sell research compounds and want your catalogue compared accurately, write to us. What helps most, in rough order:
- A public product page per item, with the price and pack size readable without an account.
- Certificates of analysis published at stable links, named by product and batch.
- A note when pricing, sizes or stock change materially, so listings do not go stale.
- A correction, any time you see something wrong on your profile.
We will correct a wrong price or a dead link whether or not there is any commercial relationship between us. Accuracy is the product.
Affiliate disclosure
Some outbound links on PepLookup are affiliate links, meaning we may earn a commission if you buy through them, at no extra cost to you. This is how the site pays for itself. It does not change prices, rankings or which suppliers we list. The full disclosure sits in our legal disclaimer and the terms of service.
