For vendors & affiliate partners

pep.deals is an independent comparison site for research-use-only peptides. Buyers land here to compare landed cost per milligram across vendors, check transparency signals, and grab a working coupon before they check out. Then they click through to a vendor to buy. That last click is high-intent traffic, and it can be yours.

This page explains how listings work, how we rank, and how we partner with affiliate programs. If you run a peptide storefront, this is the context for any application you receive from us.

How listings work

We read your public storefront on a daily schedule and list your products alongside everyone else's, normalized to cost per mg. There is no fee to be listed and no fee to rank well. The way to rank well is to offer good value and clear paperwork.

Every product row links to your own product page. Every vendor gets a profile with transparency badges covering certificate-of-analysis recency, business age, US shipping, reship policy, payment options, and refunds. Each badge cites its evidence, and buyers see it before they choose where to spend.

We rank by value, not commission

The table sorts by landed cost per mg by default. Commission has no effect on order or visibility, and we will not sell placement. This is the whole reason buyers trust the comparison, and it is the reason your listing is worth something to them.

Outbound buy links are marked as sponsored and no-follow, and our affiliate relationship is disclosed on every page and on a dedicated disclosure page, in line with FTC guidance.

Working with your affiliate program

If you run an affiliate or referral program, we are glad to join it. Until an approved tracking link is in place, we link to your plain product pages, so a listing never waits on paperwork. Once you approve us, we swap in your tracking template per vendor and reconcile through whatever your program supports, whether that is a sub-ID on the outbound link or a coupon and time-window fallback.

We keep attribution clean and honor your program terms. We do not stuff cookies, spoof referrers, or bid on your brand terms.

Corrections and fast fixes
