Put your prices in front of buyers who already compared.

pepmg is an independent cost-per-mg index for research peptides. We send researchers who've already decided what to buy straight to the vendor with the best $/mg — high-intent, bottom-of-funnel traffic. We currently track 379 listings across 21 vendors and 21 compounds.

Why list with us

  • We rank on math, not money. Placement is by $/mg — a paid relationship never reorders the table. Buyers trust that, which is why the clicks convert.
  • Qualified, bottom-of-funnel traffic. Nobody lands on a $/mg comparison table by accident. They're ready to buy.
  • Transparency that protects you. Every price is stamped with when we fetched it and links to your own page. No stale prices, no misrepresentation.
  • You stay in control. Buyers check out on your site, under your terms. We're a referrer, not a reseller.
  • Accuracy support. Give us a feed or a contact and we'll keep your listing current and fair.

Three ways to work together

Offer a pepmg code (easiest)

Give us a discount code — say PEPMG — and researchers get a reason to choose you while you get clean attribution on every buyer we send. No network to join, no reseller terms; checkout stays on your site.


Affiliate / referral

Prefer a tracked link? We'll attribute the qualified traffic we already send you. Standard research-peptide terms (typically 10–25%) work fine.


Accurate listing (free)

Not ready for either? We'll still list you accurately — just give us a contact to confirm pricing and stock.

The transparency promise

pepmg discloses every material connection inline (FTC compliant). Where we have an affiliate relationship, the listing says so and shows the code. Where we don't, it says "independent listing — earns nothing." Your customers always know exactly what they're looking at.
All products listed are sold by third-party vendors for laboratory and research use only (RUO). pepmg sells nothing, ships nothing, and gives no medical, dosing, or human-use guidance. Listings are price-tracking data, not endorsements.
