Key findings

  1. 01

    211 stores sell to buyers in the US. 130 are based in the US and 81 ship in from abroad: 1 from Denmark, 33 from the UK, 1 from Lithuania and 46 that do not say where they are based.

  2. 02

    82% of stores based in the US say their products are third-party tested; none of those claims has been checked yet. 107 of the 130 stores based in the US (82%) say on their own website that their products are third-party tested, and 102 link a page of certificates of analysis. PepFinder has not yet reviewed a certificate from any store serving the US, and one store serving the US has passed a PepFinder staff check. These are the stores' statements, not results we have confirmed; stores may hold certificates we have not seen.

  3. 03

    67 in 100 listed prices can be compared like for like. Of 8,950 listings priced in USD by stores serving the US, 5,996 (67%) state a price, form and quantity we can read with confidence. The rest are held back from every figure here: other forms such as pens and kits, listings with no quantity or no price, and prices that failed our checks.

  4. 04

    The same peptide sells at very different prices. Retatrutide is the most widely listed: the middle half of 272 single-vial listings from 67 stores runs from US$5.90 to US$10.00 per mg (median US$7.63), and the most expensive is 4.6 times the median. A 10 mg vial, the size most often listed, has a median listed price of US$90.00. Part of any per-mg spread is vial size, since larger vials usually cost less per mg.

Who sells to buyers in the US

Testing and certificate figures count what each store's own site says. For the other stores we found no such statement or have not yet read that part of the site, so this does not say how many do not test. A certificate counts as reviewed only once PepFinder holds it and has checked it.

Of the 5,996 compared prices, 5,245 are single vials and 751 are packs of several vials. The price figures below use single vials only, so a bulk price is never set against one vial.

Listed price per mg in USD, single vials

Each peptide with at least 5 compared listings from 3 stores, most listed first. The middle half is the 25th to 75th percentile of listings. Part of any spread is vial size: larger vials usually cost less per mg. The most common vial column shows what the size most often listed costs.

How the figures are built

Stores serving the region
Published, active suppliers based in the market or stating they ship to it.
Based in the region
The supplier's recorded country is in the market.
Third-party testing
What the supplier's own website states. 'stated' is a claim, not a verified result; 'notFound' means we read the site and found no such statement; 'notAssessed' means not yet read.
Certificates page
The supplier's site links a page of certificates of analysis. Not a check of any certificate.
Certificates reviewed
Suppliers with at least one certificate PepFinder holds and has reviewed.
PepFinder check
Suppliers with a PepFinder staff verification check passed and not expired.
Compared price
Listed price in the market currency whose form, total mass and currency we could read with confidence, not held for review and not an outlier. Only VALID prices enter the distributions.
Single vial
One vial of powder of one peptide. Packs of several vials, pens, capsules, sprays, kits and blends are excluded from the distributions.
Minimum sample
A peptide is reported once it has at least 5 listings from 3 suppliers.
One business, several sites
A business trading through several confirmed storefronts is counted once per identical listing.

Prices are listed prices as each store's site showed them when last checked, without shipping or tax. Nothing here describes what the products do or how they are used; they are sold for laboratory research. How we collect and validate prices · Legal status in the US.
