Excalibur Peptides publishes two retatrutide certificates on its own COA page, and neither one names Excalibur: one lists the customer as "Finnrick" and the manufacturer as "n/a," the other lists the client as "Ascend.Science." Its COA page promises testing that leaves every batch "endotoxin free," yet the Finnrick certificate states outright that its own testing purpose does not cover endotoxins, and the advertised Trustpilot rating of 4.7 from 12 reviews links to a profile Trustpilot has removed. Has anyone received a shipment recently and can confirm which certificate, if any, actually arrives with the order?

$129.90
Compound retatrutide 10mg
Listed as GLP-3R Peptide, 10mg Research Peptide, described on the page as "a structural analog of retatrutide" and "not retatrutide"
Price as recorded $129.90 (struck through from $152.00); a second, duplicate 10mg listing shows $129.99 from $141.40
Read on 2026-08-24. One reading on one day, and prices are not tracked over time here.
No Trustpilot listing for this supplier could be read on 2026-08-25.
Terminus read the standing of the listing itself and nothing under it. The reviews behind any figure above were not gathered, read, or checked here, and no reader review on this site feeds that number.
19 claims from this publication's own dossier on this supplier were read again against the live site on 2026-08-24: 18 held, 1 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.
Dated entries
4 observations on file, 2026-08-24 to 2026-08-25. Newest first, appended and never rewritten.
Trustpilot claim checked directly, and the vendor's own link leads to a removal notice. Read today: the homepage advertises "Rated 4.7 out of 5 from 12 verified reviews on Trustpilot" beside the line "Verified, third-party reviews from researchers on Trustpilot", and its "Read all reviews on Trustpilot" button links to https://www.trustpilot.com/review/excalibur-peptides.com. That exact URL returns a page titled "This profile has been removed", reading verbatim: "The business you're trying to find goes against our guidelines and is no longer visible on Trustpilot." A separate live Trustpilot profile does exist for the unhyphenated sibling domain at trustpilot.com/review/excaliburpeptides.com, showing 4.6 out of 5 from 32 reviews, with its logo linking back to excaliburpeptides.com. So the advertised figures of 4.7 and 12 reviews match neither the removed profile nor the live one. Trustpilot returned HTTP 403 to a direct request from here, so both profile pages were read through the r.jina.ai text reader today, while the homepage was fetched directly. I have not established when the profile was removed, why, or whether the two domains are commonly owned.
On certificates: certificates ARE published as images at /coa-lookup/, twelve tabs covering Selank, Reta-60, GHR, Tesamorelin, Wolverine, GLP R3, LL-37, MOTS-C, TB-500, NAD+ 500, GPL R2 and TB500. The page states that every batch of Excalibur peptides compounds is "independently tested by Freedom Diagnostics" to ensure a 99 percent purity level, "endotoxin free, and accurate identification." I downloaded and read both retatrutide-related certificates in full. The one filed under GLP R3 is not from Freedom Diagnostics. It is a "Finnrick Testing Certificate" bearing the BTLabs logo, Test Certificate ID 3w57jtc, Report # IF-824-QSA-TR006-BTL26493-16, dated 5/22/2026 and tested 5/18/2026, Testing material "Retatrutide", Lot Number 3W57JTC, BT Sample ID 005000040093106, labeled content 10 mg. Findings by USP methods: General Appearance USP <630> white powder, Mass USP <41> 53.3 mg, FTIR Identification USP <197A> confirming "the presence of Retatrutide with addition of excipient(s)/fillers", HPLC Purity of Peptide Assay USP <621> against a specification of ">= 98 %" returning 99.8 %, HPLC Potency Assay USP <621> returning 10.2 mg or 101.5 % of label, and Peptide-to-Excipients Ratio USP <1151> returning 10.2 : 43.1 mg, a ratio of 1:4.3. Signed by Andrea Castro, AS, Scientist-II and Verna Zheng, AS, Scientist-II of BTLabs, 5601 Corporate Way Suite 206, West Palm Beach, FL 33407, phone (561) 941-4835, btlabtesting.com. That certificate's Customer field reads "Finnrick" and its Manufacturer field reads "n/a", so the document does not name this vendor anywhere. The second certificate, filed under Reta-60, IS a Freedom Diagnostics document: accession 2605070269, search code Asce2605070269, received 05/07/2026, reported 05/09/2026, product "GLP-3 RT 60mg", identity confirmed by LC-MS as "GLP RT", Purity (HPLC-UV) 99.89%, Net Content 65.77 mg, two endotoxin replicates passing by Limulus Amebocyte Lysate assay per USP <85> at a stated sensitivity of <=0.05 EU/mL, signed Alex Johnson, Principal Chemist. Its Lot field reads "Clear Cap" rather than a lot number, and its Client field reads "Ascend.Science". Freedom Diagnostics is independently reachable at freedomdiagnosticstesting.com, Franklin, TN, and runs a public register, which I queried directly today.
On prices and policies: prices are public with no login and no age interstitial. Every catalog item displays a struck-through anchor price beside a lower current price. Recorded: GLP-3R Peptide 10mg $129.90 from $152.00, and a separate duplicate listing, "GLP-3 R, 10mg Research Peptide", at $129.99 from $141.40; GLP-2 T 10mg $99.99 from $105.00; Tesamorelin 10mg $99.90 from $104.80; KLOW Blend 10/10/50mg $179.99 from $184.99; Wolverine Blend 10mg/10mg $139.99 from $141.00; TB-500 10mg $89.99 from $93.98; LL-37 5mg $74.99 from $78.34; GHK-Cu 50mg $64.99 from $69.70; MOTS-C 10mg $59.99 from $63.23; NAD+ 500mg $49.99 from $56.22; BPC-157 $49.99 from $53.50; GHRP-6 5mg $39.99 from $45.30. Five multi-compound bundles run $189.97 to $289.97. Shipping per /shipping-and-return/: FedEx 2-Day, "Complimentary on orders over $50; a flat $15 rate applies to orders below that threshold", same business day dispatch for orders before 4:00 PM Eastern Monday to Friday, delivery expected within 48 hours of dispatch in the contiguous US, confirmation and tracking emails. Handling per the homepage: "Every batch is freshly produced, flash-frozen, and cold-stored at -10 F before being vacuum-sealed", and the product page gives storage as "-20 C, protect from light". Refunds: "all sales are final once an order has been placed", no returns and no change-of-mind cancellations; responsibility for the package transfers to the customer at carrier delivery confirmation, with porch or mailroom theft excluded; damage or fulfilment errors must be notified within 7 calendar days with an unboxing video plus photographs of the external packaging, contents and packing slip; and resolution is replacement only, stated verbatim as "Because of regulatory requirements around these products, cash refunds and store credit aren't available but a verified error will always be made right with a replacement". A chargeback section asks customers to contact support first and warns that filing first "may affect your ability to order with us in future". Contact details published: info@excalibur-peptides.com, +1 (904) 290-4046, and "Proudly based in St. Johns, FL". Payment brand marks are published, in a form a text scrape will miss: a lazy-loaded banner image sits in the HTML of every page I fetched, at /wp-content/uploads/2026/07/payment-product-1024x123.webp, carried on a data-src attribute rather than as page text. I downloaded and viewed the file today. It shows, left to right, a 4Square mark, PLAID, Interac, VISA, MasterCard, Bitcoin, Ethereum, Bitcoin Cash, Solana, Zcash, TRON and Dogecoin. That is a display of marks and not a checkout, and I did not transact, so which of them functions at checkout is UNVERIFIED. Research-use-only language is present on the homepage, both product pages, the COA page and in the footer of every page.
CAUTIONCautions. 1. Neither published retatrutide certificate names this vendor. The GLP R3 certificate lists its Customer as "Finnrick" and its Manufacturer as "n/a". The Reta-60 certificate lists its Client as "Ascend.Science", and the vial photographed on that certificate is branded "Ascension LABORATORIES" with "AscensionLaboratories.com" printed on the label, alongside "GLP-3 RT" and "60mg". The label also carries a 99 percent purity marking, which is not legible at the resolution of the image the vendor hosts and which I read instead from the higher-resolution photograph inside the laboratory's own stored copy of the same document, described below. I checked this against the issuing laboratory's own public register rather than inferring it: querying Freedom Diagnostics' public COA index returns 22 certificates under the search-code prefix "Asce", and accession Asce2605070269 is among them, while Excalibur has its own separate set of 10 certificates under the prefix "Exca", running Exca2606090420 through Exca2608030569. So the vendor does hold Freedom Diagnostics certificates of its own, and the retatrutide certificate it publishes is not one of them. I then pulled the laboratory's own stored copy of that accession from coas.freedomdiagnosticstesting.com and set it beside the image the vendor publishes. The two carry the identical Ascension Laboratories vial photograph and the identical ESI+ mass spectrum, annotated "GLP RT [M+3H+K]+4", "GLP RT [M+4H]+4" and "GLP RT [M+3H]+3" over the same values on the same 350 to 1750 m/z axis, the laboratory copy simply at higher resolution. The document filed under the Reta-60 tab is the certificate the laboratory holds for its client Ascend.Science. 2. The named lab does not match the published document. The COA page says every batch is "independently tested by Freedom Diagnostics", while the certificate filed under GLP R3 was issued by BTLabs through Finnrick. 3. The endotoxin claim is contradicted by the document under it. The COA page says the testing ensures products are "endotoxin free", while the GLP R3 certificate states in its own Testing Purpose that the analysis "does not provide information on particulate matter, microbial contamination or presence of endotoxins". 4. The storefront and its certificates disagree about what the compound is. The product page states, verbatim, "GLP-3R is supplied strictly as a laboratory reference compound, it is not retatrutide, not an FDA-approved drug", and lists the reference compound as "Retatrutide (LY3437943) analog", while both certificates published for it identify the tested material as Retatrutide, one under "Testing material: Retatrutide" and "Labeled as: Retatrutide", the other as "GLP-3 RT" identified by LC-MS as "GLP RT". 5. Purity is claimed catalog-wide and unqualified in several places: a 99 percent minimum purity figure and "99%+ HPLC-verified purity" on the homepage, a 99 percent purity guarantee badge on both product pages, and a stated 99 percent purity assurance on the COA page, none scoped to a lot. 6. Two duplicate listings of the same 10mg product carry different anchor prices, $152.00 and $141.40, discounted to $129.90 and $129.99, and the homepage best-seller strip shows a third figure, "GLP-3R 129.99", beside the tile showing $129.90. 7. The dispatch cutoff is published two ways: "Same day processing on order before 2pm EST" on the homepage against "before 4:00 PM Eastern Time (EST), Monday through Friday" on the shipping page. 8. Claim instructions give support@excaliburpeptides.com while the same page's footer gives support@excalibur-peptides.com and the site footer gives info@excalibur-peptides.com. The unhyphenated domain is a separate live site on a different host, and it is not a hostile lookalike: excaliburpeptides.com serves the same branding, with a page title of "Excalibur Peptides | Lab-Grade Research Peptides USA 2026", an og:site_name of "Excalibur Peptides, Research Peptides USA", and meta descriptions naming the same house codes GLP-2T and GLP-3R. I did not confirm common ownership of the two domains, only that both present as this brand, so a customer emailing either address is plausibly reaching the same operation. 9. The site carries production copy that reads as unfinished or unproofed, including a homepage feature block whose body text is "Compliance language stays clear without overwhelming discovery", a "Lot-specifi COA" heading, and footer text reading "Tihird Party Tested", "COA Avelable", "Proudly US Base Ships within 2-4 Bussiness Days", "Mon-fri 9AM- GPM EST", and a research-use disclaimer rendered as "Not for human opr vetinary consumption, Products are nit intended to diagnose," followed by two therapeutic-claim verbs and "or prevent any diseases". 10. The homepage advertises "Rated 4.7 out of 5 from 12 verified reviews on Trustpilot". I did not open Trustpilot, so that rating is UNVERIFIED, and both retatrutide product pages show "There are no reviews yet."
