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.
Luxara Labs' own certificate PDF and the laboratory's live copy of the same report disagree with each other: for report EJ-RETA-60-061526 the vendor's hosted document states 58.02 mg and 96.7 percent fill accuracy against a 60mg label, while Testides' own endpoint serves 61.83 mg and 103.0 percent for the identical report number, with the purity figure unchanged between the two copies. The site never names either of its two laboratories, SideChain Analytics or Testides, anywhere in its body text, so a visitor learns who tested a batch only by opening the certificate PDF itself, and the unqualified '99%+ Purity' badge on the shop header sits apart from the lot-specific, method-qualified figures on the documents it never links to by name. A reader who has ordered a recent batch could say which of the two conflicting content figures for that 60mg lot, the vendor's or the laboratory's, matches what shipped.

Read on 2026-08-25. 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.
8 claims from this publication's own dossier on this supplier were read again against the live site on 2026-08-25: 0 held, 8 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.

The certificate library at /lab-results/ published 53 distinct PDF links when I read it today, each appearing once in the markup, indexed by product, strength, lot number, test date, purity and measured mass, with a search box and a header reading "Independent 3rd Party Testing", "HPLC-UV" and "Batch/Lot Specific". Retatrutide entries listed: 10mg lot R18623 tested August 14 2026, purity 99.5%, mass 10.32 mg, with an additional lot R18318 dated February 4 2026; 20mg lot R27798 tested July 2 2026, 99.76%, 22.31 mg; 30mg lot R37112 tested July 2 2026, 99.45%, 29.56 mg; 40mg lot R42321 tested August 23 2026, 99.6%, 43.77 mg; 60mg lot R60338 tested July 2 2026, 99.66%, 58.02 mg. I downloaded three of those PDFs with curl and read their text layers rather than opening them in a browser. The 10mg document is a two-part report issued by SideChain Analytics: Lab ID RET-262_D, report number COA-2026-SC-00986, lot R18623, CAS 2381089-83-2, formula C221H342N46O68, molecular weight 4731.3 g/mol, total mass 87.7 mg, received 08/10/2026, analysed 08/14/2026, reported August 14 2026. Method is named on the face: "Qualitative and Quantitative chemical analysis by Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS)", METHOD B, Agilent 1290 Infinity II plus 6495 QQQ, ESI positive, precursor [M+5H]5+ at 947.90 Da, quantifier MRM transition 947.9 to 136.1 at CE 30 V, qualifier 947.9 to 110.1 at 35 V, retention time 3.634 min, column Agilent Poroshell 120 EC-C18 2.1 by 100 mm 2.7 micron, 0.1 percent formic acid in water and acetonitrile. Findings: net peptide content specification 10.00 mg, measured 10.32 mg; peptide label accuracy specification 90 percent, measured 103.2 percent, PASS; chromatographic purity specification 98 percent, measured 99.5 percent. The document defines its own purity term, that chromatographic purity "bounds peptide-related impurities only, not excipients, counter-ions, or residual water" and cites Ph. Eur. 2.2.46. Page two is a separate endotoxin certificate, COA-2026-SC-00986-EN, analysed 08/16/2026, aliquot mass 10.8 mg, measured less than 0.116 EU/mg against an acceptance limit of less than 0.15 EU/mg, PASS, by "Kinetic Chromogenic LAL/TAL Endotoxin Test (USP <85>)" naming the kit, the reagent, the SpectraMax 340PC-384 instrument, a 0.005 to 10 EU/mL log-log standard curve and 100 percent spike recovery. The 40mg document is the same lab and format: RET-345_D, COA-2026-SC-01423, lot R42321, received 08/18/2026, analysed 08/23/2026, total mass 152.0 mg, net peptide content 40.00 mg specified against 43.77 mg found, label accuracy 109.4 percent PASS, purity 99.6 percent, verification code 2YtnK4xdl4lVVz5qNJRfNA. The July 60mg document is from a different laboratory, Testides: report number EJ-RETA-60-061526, client Luxara Labs, vendor Luxara Research Company, lot R60338, requested Jun 21 2026, received Jul 2 2026, tested Jul 6 2026, "HPLC-UV PURITY & CONTENT ANALYSIS" with a chromatogram at 214 nm, expected content 60.00 mg against 58.02 mg measured, purity 99.66 percent, fill accuracy 96.7 percent, appearance white lyophilized powder, cap colour blue, "CERTIFIED BY TESTIDES, testides.com".
On lab verifiability, and this is a direct disagreement with the buyer walk of 2026-08-24, which recorded that the two most recent retatrutide PDFs opened as nothing but a 375 by 500 photograph of a vial with no chromatogram, no analytical text and no lab name. Fetched today with curl, both the 10mg August 14 file and the 40mg August 23 file are full text-layer analytical reports naming SideChain Analytics, the method, the instrument and the transitions, as quoted above. I cannot say whether the files were replaced in the intervening day or whether the earlier read was of a different rendering; I can say what the files contain today. SideChain Analytics is independently locatable: sidechainanalytics.com resolves to a live laboratory site whose meta description reads "Independent peptide testing in Canada - identity, purity and net peptide content by LC-MS/MS. Verifiable, research-use-only reports from our Mississauga lab", its application bundle publishes the address "16 Falconer Drive, Unit 14, Mississauga, Ontario L5N 3M1" and the contact info@sidechainanalytics.com, and it states "We don't manufacture, we don't sell compounds, and we have no commercial interest in the outcome of any analysis we perform." I exercised its verification route rather than describing it. Its public endpoint /api/verify/by-number returned {"ok":true,"verification_code":"xkJxbqT72cKbE5YUY2Wdhw","sample_code":"RET-262_D"} for certificate COA-2026-SC-00986 and {"ok":true,"verification_code":"2YtnK4xdl4lVVz5qNJRfNA","sample_code":"RET-345_D"} for COA-2026-SC-01423, both sample codes matching the Sample IDs printed on the PDFs and the second verification code matching the one printed on the 40mg document. A control, COA-2026-SC-99999, returned HTTP 404 and "Certificate not found". The second laboratory can be checked as well, though what it publishes sits inside an application bundle rather than on a marketing page: testides.com serves a client portal shell titled "Testides - Client Portal", and the bundle behind that shell carries a public landing route, a laboratory shipping address at 4211 Yonge Street, Suite 230, Toronto, ON M2P 2A9, and a priced method menu covering an HPLC identity, purity and quantitation panel, an LAL endotoxin assay, a four-metal ICP-MS panel, headspace gas chromatography, and an antimicrobial panel citing USP <2021> and <2022>. A public lookup is exercisable there too: the per-report /pdf endpoint served the 60 mg certificate for report EJ-RETA-60-061526, while a control one digit off answered HTTP 404. On accreditation, SideChain claims none on its own site, and Testides shows an "ISO 17025-Aligned" badge, which is alignment wording and not a claim to hold the accreditation. The words accreditation, ISO 17025, A2LA and CLIA appear in none of the three certificates I read.
Benchmark and prices read on 2026-08-25 from the product page and the WooCommerce store API, which reports USD for this request. Retatrutide is listed under its own name, titled on the page "Retatrutide Triple Agonist (GLP-1/GIP/GCG)", with size variants priced at 10 mg $90.00, 20 mg $150.00, 30 mg $198.75, 40 mg $247.50 and 60 mg $337.50. The terms state that "Canadian addresses will populate in CAD, and USA addresses will populate in USD", so the currency shown depends on the destination. Also recorded: Klow 80mg $145.00, Glow 70mg $135.00, Selank Amidate 50mg and Semax Amidate 50mg $135.00 each, L-Carnitine 2000mg/10mL $135.00, Tirzepatide from $60.00 to $202.50, BPC-157 from $60.00 to $112.50, BPC157/TB500 from $63.75 to $165.00, Tesamorelin from $90.00 to $165.00, NAD+ from $75.00 to $135.00, GHK-Cu from $48.75 to $75.00, TB500 10mg $63.75, Ipamorelin 10mg $57.38, Melanotan II 10mg $41.25, Hospira Pfizer bacteriostatic water 30ml $25.00. The catalog holds 52 products in the store API and 52 product URLs in the sitemap as read on 2026-08-25, and that number moves inside a single day, so it is a snapshot rather than a size. A sitewide bar reads "Free Express Shipping on Orders $450+ | CJC-1295/Ipamorelin - 10% Off This Week", a popup offers 10 percent off a first order for an email address, and the shop header states "Bulk orders save 20% on 10+ vials". No standard shipping rate is published on the shipping page, the terms or the product page. The product page is more specific than a general index once a size is chosen: each size variant's variation payload carries a lot number, a purity figure, a measured mass, a test date and a per-lot certificate URL, and an inline script paints those fields into a panel on selection, so a buyer who picks a size is shown that lot's document rather than the /lab-results/ list. The 40 mg variant is the exception, its test-date field empty. What the page still omits is the analytical method, a storage instruction and a reconstitution instruction. It publishes "99%+ Purity Standard" and "Ships From Ontario, Canada", with Canada delivery typically 1 to 3 business days and USA 3 to 5. The refund position: "Due to the sensitive nature of our products, returns are not accepted. Refunds may be issued only in cases of incorrect or damaged items, following review and confirmation by our team." On lost packages the terms are longer than most in this group and set a 48-hour reporting window from the carrier's recorded delivery time, then state that "A carrier-confirmed delivery does not automatically qualify for a refund or replacement" and that title and risk pass to the buyer upon shipment. Research-use-only language is on the product page in two places and repeated in a footer disclaimer that includes "Any form of bodily introduction, direct or indirect, is prohibited by law", and an age modal asks the visitor to confirm being at least 21 and a research professional. Identity: "Luxara Research Company" in the footer copyright, email info@luxaralabs.com and telephone 289-588-7939, with no street address and no registration number published on any page I loaded. Sitewide structured data fills part of that gap and muddles it at the same time: it publishes a partial Ontario address with no street line, carrying the postal code L4B 4V1, and its legal-name field holds a personal mailbox at a free email provider rather than a company name. The same structured data states a delivery time of one to two days, against the one to three business days for Canada printed on the product page.
CAUTIONCautions noted. First, the vendor never names its own laboratories. SideChain Analytics and Testides appear only inside the PDF files; the strings sidechain and testides return zero hits on the /lab-results/ index, the transparency page, the quality-standard page, the how-to-read-a-coa page and the research-standards-methodology page. A visitor who does not open a document cannot learn who tested anything, and the index's own header badge reads "HPLC-UV" while the two most recent retatrutide certificates are LC-MS/MS. Second, two different laboratories are in use across the same product line, SideChain Analytics on the August documents and Testides on the July ones, with no explanation on the site of when or why the testing moved. Third, the catalog-wide claim is unqualified: "99%+ Purity" appears on the shop header, the product page badge and the site's promotional copy with no method attached at the claim site, while the documents that would qualify it are method-specific and lot-specific. Fourth, measured content runs over the labelled amount on most lots and the certificates report it plainly as label accuracy, 103.2 percent on the 10mg lot and 109.4 percent on the 40mg lot, but overage is the common pattern rather than the rule. Two of the five current retatrutide lots measure under label on the vendor's own copies, 29.56 mg against a 30 mg label and 58.02 mg against a 60 mg label, the latter printed as 96.7 percent fill accuracy, which the eighth item below shows the laboratory's own copy contradicting, and the Selank, Kisspeptin and NAD+ lots in the index sit under label as well. Nothing on the product page explains the variance to a buyer. The index also disagrees with a certificate about a date: it prints July 2 2026 as the test date for the 60mg lot, while the document itself gives Date Tested Jul 6 2026 and Jul 2 2026 as the date received, so the index has repeated the received date as the test date. Fifth, the site publishes a page titled "Best Fat-Loss Peptides in Canada: Evidence-Based Research Review 2026" at /fat-loss-peptides-canada/, which puts a body-composition outcome in a page title, a URL and the internal link text of a storefront, even though the body of that page is carefully hedged and repeats that all compounds discussed are for research and laboratory use only. Sixth, the site publishes a "Peptide Reconstitution Calculator" at /peptide-calculator/ which takes a syringe volume, a vial quantity, a diluent volume and a dose, and returns a syringe unit mark, printing lines of the form "For a dose of 1 mg pull the syringe to 20". A syringe-unit output on a storefront is a different class of content from stating what a compound is, and the page's own footer disclaimer states that any form of bodily introduction is prohibited by law. Seventh, on the count: the buyer walk recorded 113 certificate PDFs each emitted twice with lowercase variants that returned 404. Today the index emits 53 PDF hrefs, each once, and I found no duplicate-case pairs, so either the page was rebuilt or the earlier count included the duplicates. Eighth, the vendor's copy of a certificate and the laboratory's copy of the same report do not always agree, so a fill-accuracy figure taken from this site is not a settled measured value. For report EJ-RETA-60-061526 the vendor-hosted PDF states 58.02 mg and 96.7 percent fill accuracy, while the copy the laboratory endpoint serves under that same report number states 61.83 mg and 103.0 percent. For report EJ-RETA-20-061526 the vendor copy states 22.31 mg and 111.5 percent, against 23.77 mg and 118.9 percent on the laboratory copy. The 30 mg pair and the February 10 mg pair are identical, and purity is unchanged in every pair, the 60 mg document reading chromatographic purity by HPLC-UV at 214 nm of 99.66%. The laboratory endpoint renders each document with a current generation stamp, so its copy may reflect a later change to the record, and nothing on either site explains the difference.
