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 3820 listings across 110 vendors and 79 compounds.

▸ Why list with us

We rank on math, not money. Placement is by $/mg — a paid relationship never reorders the table.
Transparency that protects you. Every price is stamped with when we fetched it. No stale prices, no misrepresentation.
You stay in control. Buyers check out on your site, under your terms. We're an index, not a reseller.
Accuracy support. Give us a feed or a contact and we'll keep your listing current and fair.

▸ Working together

Vendor links are temporarily offline while we review our referral and linking policies. Listings remain for price transparency. We are not taking on codes or referral arrangements while that is the case, and we are not sending you traffic — so the only thing on offer today is an accurate listing.

Accurate listing (free)

This one is always on. We'll still list you accurately — just give us a contact to confirm pricing and stock.

▸ The transparency promise

pepmg links to no vendor site at present, so no listing on this site earns pepmg anything and none is a paid placement. Listings show your name, your published sizes and prices, and the $/mg they work out to, stamped with when we fetched them. When outbound links return, every material connection is disclosed inline (FTC compliant) and ranking stays $/mg arithmetic either way.

All products listed are sold by third-party vendors for laboratory and research use only (RUO). Where an FDA label or a peer-reviewed study has published a dose, pepmg reports it with the source named, because that is safer than guessing. It is a report, not medical advice and not a recommendation to use anything. pepmg sells nothing and ships nothing. Listings are price-tracking data, not endorsements.
