Never merged into one number. Some supplier links here are referral links, marked where they appear, which pay Terminus Research when a reader buys. The same terms are open to every supplier in the ledger, apart from the one exception the referral policy page names, participation changes no score, rank, caution, or coverage decision, and a link is not an endorsement.
Koi Aminos sells nothing itself: every Buy Now button on koiaminos.com routes off-domain to kylopeptides.com, and eight of the ten pages listed in the site's own sitemap and navigation, including the coa page its own retatrutide FAQ tells a buyer to use for looking up a lot number, return an identical page-not-found body under a direct fetch. The site's structured data names koipeptides.com, under the entity Koi Research Labs LLC, as the same organization, yet every actual purchase routes instead to kylopeptides.com, operated by a differently named entity, Kylo Labs LLC, that happens to share koipeptides.com's identical Wyoming registered address down to the suite letter. Prices displayed on koiaminos.com disagree with the kylopeptides.com page a buyer is actually sent to for three of the four retatrutide sizes, by five to ten dollars in either direction, and the 60mg size koiaminos.com shows in stock at $449.95 is marked out of stock and priced $459.95 on the site where it would actually be bought. Has anyone who ordered through koiaminos.com's link seen the final kylopeptides.com checkout price match what koiaminos.com displayed, or run into the higher figure instead?
What the record holds
NO FIRM COMMITMENT
“Koi Aminos LLC does not manufacture, warehouse, or ship any products”
The marketplace front publishes no dispatch terms of its own: its footer disclaimer states all transactions are processed by its fulfillment partner, and the operative terms are kylopeptides.com's (that record carries the same-day cutoff). Classed on this site's own published language under the weaker-when-ambiguous rule.
Read from this supplier's own pages on 2026-08-26. This publication has never placed an order with any supplier. This row records what is written and measures nothing about what actually happens after an order.
$89.95
Compound retatrutide 10mg
Listed as GLP-3 RT (Retatrutide) at koiaminos.com/catalog/glp-3-rt, whose Buy Now button redirects to kylopeptides.com/product/glp-3-rt/
Price as recorded $89.95 USD for a single 10mg vial on koiaminos.com's own product page, matching the $89.95 charged for the same size on kylopeptides.com, the site the purchase actually routes to; koiaminos.com's larger sizes (20mg $164.95, 30mg $239.95, 60mg $449.95) diverge from kylopeptides.com's own prices for the same sizes (20mg $169.95, 30mg $229.95, 60mg $459.95, the last marked out of stock there)
Read on 2026-08-26. One reading on one day, and prices are not tracked over time here.
This supplier was not part of the Trustpilot reading of 2026-08-25, which covered 59 of the 126 suppliers on file. That is a fact about this publication's coverage, stated rather than left to be read either way.
4 claims from this publication's own dossier on this supplier were read again against the live site on 2026-08-26: 1 held, 3 corrected before publication.
A corrected claim is an error of ours that the re-read caught before it reached a page. This line tracks this publication's own accuracy. It says nothing about the supplier.

koiaminos.com presents as a seven-product marketplace, GLP-3 RT (Retatrutide), GLP-3 R (a lipidated retatrutide variant), GLP-2 TZ (Tirzepatide), AOD-9604, Tesamorelin, Sermorelin and MOTS-c, and states outright on both the catalog page and every product page that every order is fulfilled by Kylopeptides.com, described as the number one peptide brand online, with each Buy Now button linking off-domain to a kylopeptides.com product URL carrying UTM referral tags. The site's own sitemap-pages.xml lists ten page URLs, home, catalog, coa, research, about, contact, faq, legal/disclaimer, legal/terms and legal/privacy, with legal/disclaimer sitting directly in the sitemap file as re-read today, and the homepage's own navigation links to the identical set. Fetched today, only the homepage and the catalog and per-product catalog pages render real content; every one of the other eight, coa, research (including its own listed article slugs such as /research/retatrutide-glp-3-rt-research-review), about, contact, faq, legal/terms, legal/privacy and legal/disclaimer, returns HTTP 200 but the page body is the site's own client-side page-not-found component, an identical 6,609-byte payload on all eight. This is a static-fetch reading and does not rule out a script-driven route that only resolves once client-side JavaScript takes over after the not-found shell first paints, but every one of these eight URLs is both sitemap-listed and directly linked from the site's own homepage nav, so a visitor or crawler following either the sitemap or the nav lands on a dead page under a plain fetch. The retatrutide product page's own FAQ text tells a buyer that the COA is publicly available, to be accessed using the lot number on the vial from the site's COA page, and that COA page is one of the eight that does not render. The legal text itself is not actually missing: the Disclaimer, Terms of Use and Privacy Policy paragraphs are duplicated inline in the footer of every product page fetched, so the content exists, but the dedicated URLs the site's own sitemap, nav and FAQ point a reader toward do not.
Retatrutide is not actually sold from koiaminos.com; the Buy Now button on the GLP-3 RT page (10mg $89.95 as displayed) resolves to kylopeptides.com/product/glp-3-rt/, a separate WooCommerce storefront branded Kylo Peptides, legal name Kylo Labs LLC per that site's own structured data, registered at 30 N Gould St, Ste R, Sheridan, WY 82801. koiaminos.com's own Organization structured data, meanwhile, declares a sameAs link to a third domain, koipeptides.com, and a contact point at koipeptides.com/contact; koipeptides.com is itself a separate, live WooCommerce storefront branded Koi Peptides, legal name Koi Research Labs LLC per its own structured data, registered at the identical address, 30 N Gould St, Ste R, Sheridan, WY 82801, that Kylo Labs LLC uses. So koiaminos.com's own machine-readable metadata names koipeptides.com (Koi Research Labs LLC) as the same organization, while the actual purchase path on every product page routes to kylopeptides.com (Kylo Labs LLC), a differently named entity that happens to share the identical Wyoming registered-agent address with the entity koiaminos.com claims as itself; koiaminos.com's own footer names a third address again, Koi Aminos LLC, 233 E Main St, Sevierville, TN 37862, for the marketplace entity itself. A fourth related domain, koipeptidescanada.com, fetched today, carries the legal name Koi Research Labs Canada Inc. in its own structured data, a naming pattern matching koipeptides.com's Koi Research Labs LLC rather than either koiaminos.com's or kylopeptides.com's entity names, suggesting koipeptidescanada.com is the Canadian sibling of koipeptides.com specifically rather than of the koiaminos.com marketplace front. Flagging this for Fable to reconcile against any separate koipeptidescanada.com or koipeptides.com record elsewhere in this survey: koiaminos.com, koipeptides.com, kylopeptides.com and koipeptidescanada.com read today as four storefronts across a shared operation with at least three differently named LLCs in play. On the laboratory itself: the retatrutide certificate actually sold through this chain, downloaded from kylopeptides.com's own /coa/ library, carries a Freedom Diagnostics letterhead, previously verified live in this survey, client name printed as KYLO Research Labs LLC, a fifth naming variant, accession 2608170152, search code KYLO2608170152, lot SD-260728-1, received 8/17/2026, reported 8/22/2026, product Retatrutide 10mg, purity 99.87 percent by HPLC-UV, identity confirmed by LC-MS, net content 11.28 mg. I queried the laboratory's own hosted copy at coas.freedomdiagnosticstesting.com/KYLO2608170152.pdf, which returned HTTP 200 and a file byte-identical in size to the copy kylopeptides.com publishes, and a company query against the laboratory's public index returned six matching accession codes for KYLO Research Labs, confirming the laboratory hosts documents matching the vendor's copies for this lot family. A second laboratory, Vanguard Laboratory of Olympia, Washington, previously encountered in this survey with its accreditation caveat already on record there (its published A2LA scope names food, environmental and metals methods, not a peptide-purity method), supplies five further certificates in the same library, including one whose compound field reads GLP-3 rather than GLP-3 RT specifically and whose client name is typoed on the official document face as Kylo Pepties.
Benchmark read on 2026-08-26 from koiaminos.com's own retatrutide (GLP-3 RT) product page and cross-checked against the kylopeptides.com product page it actually sells through. koiaminos.com displays four sizes, 10mg $89.95, 20mg $164.95, 30mg $239.95 and 60mg $449.95, all under an AggregateOffer marked InStock with no per-size availability flag. The kylopeptides.com listing for the same compound prices the identical four sizes at 10mg $89.95 (matching), 20mg $169.95, 30mg $229.95 and 60mg $459.95 (all three larger sizes differing from what koiaminos.com displays, by $5.00 to $10.00 in either direction), and its own size selector marks the 60mg option disabled with the title Out of stock, a status koiaminos.com's product page does not carry anywhere. The 10mg benchmark price of $89.95 does match across both sites. Catalog scope on koiaminos.com: seven products, GLP-3 RT (Retatrutide) $89.95 to $449.95, GLP-3 R (a lipidated retatrutide analogue, molecular weight given as 4845.44 g/mol against 4731.33 for the unlipidated GLP-3 RT) $89.95 to $449.95, GLP-2 TZ (Tirzepatide) $89.95 to $239.95, AOD-9604 10mg $69.95, Tesamorelin 10mg $89.95, Sermorelin 5mg/10mg $59.95 to $99.95, and MOTS-c 10mg/40mg $54.95 to $159.95; every listing sells a single vial at the chosen milligram size rather than a multi-vial kit. On the actual checkout site, kylopeptides.com, the wider catalog runs to at least twenty named compounds across GLP, GHRH, copper-peptide, blend, fragment, mitochondrial, neuropeptide and bioregulator categories, and its COA library page states, without a citation I could open, that four independent laboratories are used, naming only two by name in the rows I could read, Freedom Diagnostics and Vanguard Laboratory, plus a third, Janoshik Analytical, claimed in prose to run on every lot yet appearing as the Lab value on none of the rows in the library table, twenty-six rows at a re-read late on 2026-08-26 (twenty-four at the first read that day; the table grows as new lots post). kylopeptides.com's own COA page also states a standard of seven assays before release, sterility, endotoxin, purity, identity, heavy metals, net content and batch consistency, on file before a lot ships, while the retatrutide certificate itself, and every other row in the same table, reports only purity, identity and net content; no sterility, endotoxin or heavy-metals finding appears on the documents opened. Shipping, refund and payment policy text was not separately verifiable on koiaminos.com itself, since its own terms live only inside the same footer disclaimer block already read for the certificates entry, which states plainly that Koi Aminos LLC does not manufacture, warehouse, or ship any products and that all transactions are processed by its fulfillment partner; the operative terms are therefore kylopeptides.com's, where the homepage banner states free shipping over $150 and same-day dispatch before 2 PM, and the COA page separately states a 30-day returns window. Entity and contact for the koiaminos.com marketplace front itself: Koi Aminos LLC, 233 E Main St, Sevierville, TN 37862, phone (844) 480-0125, no email address published on any page fetched.
CAUTIONCautions noted. First, eight of the ten URLs in the site's own sitemap and homepage navigation, including the one page its own product FAQ tells a buyer to use to look up a lot-specific certificate, return a dead page-not-found body under a direct fetch; a visitor arriving by sitemap, nav link, or the product page's own instructions cannot reach a COA, a contact page, or the site's legal terms as a standalone document, even though the same legal text is duplicated in every product page's footer. Second, the site's own structured data names koipeptides.com as the same organization while the actual purchase path on every product routes to kylopeptides.com, a differently named LLC that happens to share koipeptides.com's Wyoming registered-agent address; a buyer relying on the schema-level identity claim to know who they are dealing with would be pointed at the wrong storefront. Third, three of the four larger retatrutide sizes are priced differently on koiaminos.com than on the kylopeptides.com page a buyer is actually sent to, and the 60mg size koiaminos.com marks in stock at $449.95 is disabled and priced $459.95 on the site where it would actually be purchased. Fourth, kylopeptides.com's own COA page claims four independent laboratories and states Janoshik Analytical runs on every lot, yet not one of the rows in its own published COA table, twenty-six at a re-read late on 2026-08-26, names Janoshik as the testing laboratory; only Freedom Diagnostics and Vanguard Laboratory appear as Lab values in the table itself. Fifth, the same COA page claims seven assays, including sterility, endotoxin and heavy metals, are on file before a lot ships, while every certificate actually opened from that table, including the retatrutide benchmark document, reports only purity, identity and net content, with no sterility, endotoxin or heavy-metals finding present on the document. Sixth, the operating entity is named five different ways across documents this chain produces: Koi Aminos LLC on koiaminos.com, Kylo Peptides publicly with Kylo Labs LLC as its schema-level legal name, KYLO Research Labs LLC as the client name printed on its own Freedom Diagnostics certificates, Koi Peptides publicly with Koi Research Labs LLC as its schema-level legal name, and Koi Research Labs Canada Inc. on the related Canadian domain; this full four-domain, multi-LLC relationship (koiaminos.com, koipeptides.com, kylopeptides.com and koipeptidescanada.com) is flagged here for Fable to reconcile against any other record of these domains elsewhere in this survey, since a shopper on any one of them would reasonably believe they are dealing with a single brand.
