Retatrutide suppliers: what each one publishes

Retatrutide is sold online by dozens of research-chemical sellers. People are buying it whatever anyone thinks about that, and the difference between sellers that publish a checkable purity report and sellers that only claim one is not visible from a product page. This table records what twenty of the most visible sellers actually published on August 14th, 2026.

Evo does not sell peptides and has no commercial relationship with anyone listed here. There are no affiliate links on this page and no seller paid to appear on it. Inclusion is not a recommendation — several of these sellers publish nothing you can verify.

A dash means the seller did not publish it, not that we did not look. Prices are the seller’s listed price for a single vial in their own currency, before any discount code. Vial sizes differ between sellers, so the per-milligram figure is the only fair comparison — and 50 mg vials, the size easiest to compare, are sold by just 4 of the twenty.

How this page was built

Which sellers are listed. We measured who is actually visible for retatrutide rather than picking names. Twenty buying-intent Google queries — “buy retatrutide”, “retatrutide for sale”, “retatrutide 50mg” and similar — were pulled through a rank-tracking API, and every commerce domain in those results was scored by how highly and how often it appeared. That was combined with presence in Finnrick’s independent testing database, which surfaces sellers the community buys from that rank poorly on Google. The result is a visibility ranking, and visibility is not quality: some of the most visible sellers score worst below.

Where the numbers come from. Each seller’s own site was then read directly by a scraper — Shopify and WooCommerce product data where it exists, structured product markup otherwise — to capture vial sizes, prices, stock and any certificate links. Domain registration dates come from RDAP. Anything the scraper could not establish was checked by hand, and anything still unestablished was left blank. No figure on this page was estimated or inferred.

What we removed. Six sites that rank well for retatrutide turned out not to sell it. Affiliate “best retatrutide vendor” guides recommended at least one seller whose catalog contains no retatrutide at all, which is a fair measure of how much those guides are worth:

peptiq.io — Educational site — states plainly that it does not sell peptides or list vendors.
onyxbiolabs.com — Retatrutide is not in its 41-product catalog; it ranks on an article about the compound.
ascensionpeptides.com — Retatrutide is not in its 42-product catalog, despite affiliate guides recommending it as a retatrutide source.
biotechcompounds.com — Only a cagrilintide/retatrutide blend was listed, not retatrutide on its own.
seekpeptides.com — No retatrutide listing found; ranks on a dosage-calculator article.
simplepeptide.com — Catalog requires an account, so no listing, price or certificate could be captured.

What this page cannot tell you. A published certificate describes one lot at one moment. It does not tell you what is in the vial that arrives, whether the product was stored correctly, or whether the seller ships the batch they tested. Sterility and endotoxin testing are reported far less often than purity, and purity is not the same thing as safety. Prices and stock change constantly; this page is a snapshot, not a live feed.

Checking a report yourself

The strongest signal in the table costs nothing to check. Independent laboratories that test peptides — Janoshik is the most commonly cited — publish results at their own verification address, indexed by a report number. If a seller gives you a report number, you can open the laboratory’s site and read the same result the seller is quoting. A PDF hosted on the seller’s own domain cannot be checked that way, and an image of a certificate cannot be checked at all.

Three details separate a useful certificate from a decorative one: it names the compound and the lot, the lot matches what is printed on the vial you received, and the date is recent enough to describe current stock rather than a batch sold a year ago. A report with no lot number is not evidence about your vial.
