Following this record emails you when it gains a dated entry or its published claims are re-read, and nothing about any other supplier. No topic below is ticked: tick one only if you also want it in the same email.
Compiled automatically from the dated observations in this vendor's record. How we evaluate.
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.
NeuroPept Labs names Freedom Diagnostics as its tester on all 13 catalog pages, and five of those pages, including the benchmark retatrutide 10mg listing, embed the lab's own certificate images; querying Freedom Diagnostics' own search-code lookup independently returned all six of the vendor's PDFs, each matching an embedded image live on the corresponding product page, the 10mg document field for field, including its 99.803 percent purity figure by HPLC with UV detection coupled with mass spectrometry. The other eight products, among them Tesamorelin, Semax, and Ipamorelin, carry the same "Verifiable at freedomdiagnosticstesting.com" text with no certificate image and nothing locatable under the vendor's name in that lookup. The site's own /faqs/ page returns a server error whose body is unedited template copy for an unrelated retail business, its delivery terms written for Singapore, and the Terms of Service names a litigation venue, "Miami-HillsboroughCounty, Florida," that runs two unrelated counties together. Has anyone who ordered one of the eight unverifiable-labeled products, like Semax or Tesamorelin, actually received documentation on request?
What the record holds
NO FIRM COMMITMENT
“Research peptides ship quickly and discreetly from the USA with secure, tracked delivery”
The record's only shipping language is general: a sitewide banner stating Free shipping over $200 and this homepage FAQ line, with no carrier named, no delivery-time estimate, no dispatch or processing timing, and no statement restricting or permitting shipment outside the United States, so the weaker class applies.

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.

The catalog holds 13 products per /product-sitemap.xml, fetched today, and names Freedom Diagnostics as the tester on every one: the retatrutide 10mg page (/product/retatrutide-10mg-research-peptide/) states 'COA validity can be confirmed at freedomdiagnosticstesting.com using the Accession Number, Client ID, or Search Code found in the product images', and that page does embed a genuine certificate image, Reta-10mg-COA-scaled.webp, downloaded and read in full: Freedom Diagnostics accession 2603050043, client Neuropeptlabs, search code Neur2603050043, received 03/05/2026, reported 03/5/2026, product Retatrutide 10mg, lot 260217-09, net peptide content 9.56 mg, identity GLP RT, purity 99.803 percent, method stated on the document face as 'HPLC with UV Detection Coupled with Mass Spectrometry', single chromatogram peak near 15 minutes labelled GLP-RT, a mass spectrum showing [M+3H+K]4+ at 1193.30 and [M+3H]3+ at 1577.95, a photograph of two vials labelled Neuropeptlabs Retatrutide 10mg Lot 260217-09, signed Alex Johnson, Principal Chemist. Checking the other 12 products: four more carry an actual embedded certificate image rather than bare COA-verification text, retatrutide 20mg (whose own gallery and JSON-LD image array embed NEUR2607310994-scaled.webp, the Freedom Diagnostics certificate for lot 260217-12, with alt text citing 99.81 percent purity by HPLC-UV), retatrutide 30mg (two lots, 260217-01 and 260602-02), GLP-TZ (tirzepatide) 10mg (lot 260517-02) and the GLOW 70mg blend (lot GTB-202601-01), so five of the 13 products carry six embedded certificate images between them. The remaining eight products, PT-141, MOTS-c, Semax, Selank, KLOW, CJC-1295, Ipamorelin and Tesamorelin, each carry the same 'Verifiable at freedomdiagnosticstesting.com' text, but none of these eight pages has a certificate image in its gallery, only a plain product or vial photo.
Freedom Diagnostics was exercised directly rather than taken on trust, and this is the same laboratory documented independently as Full Scale Peptides' tester in an earlier dossier (freedomdiagnosticstesting.com, Franklin, Tennessee, 2 to 4 day turnaround, 42,000+ public COAs claimed on its own site). Querying its Cloudflare Worker index at coa-list.nameless-credit-789e.workers.dev with the exact company name 'Neuropeptlabs' returned six search codes: Neur2603050043, NEUR2602190053, NEUR2606020021, NEUR2607310994, NEUR2608050352 and NEUR2608050353; querying 'NeuroPeptLabs,LLC' returned a subset of three of the same six, matching a change in how the client name is printed on the newer documents. All six PDFs were downloaded from coas.freedomdiagnosticstesting.com and rendered to images for reading. The retatrutide 10mg document (Neur2603050043) matches the vendor's own webp copy field for field. The other five are: NEUR2602190053, retatrutide 30mg, lot 260217-01, 30.44 mg, purity 99.89 percent, dated February 2026, signed Stephen Schmidt; NEUR2606020021, GLOW 70mg, lot GTB-202601-01, purity 99.60 percent, identity GHK-Cu/Thymosin Beta-4/BPC-157, net content GHK-Cu 60.46 mg, BPC-157 14.81 mg, Thymosin Beta-4 13.13 mg, dated June 2026; NEUR2607310994, retatrutide 20mg, lot 260217-12, client printed as NEUROPEPTLABS,LLC, purity 99.81 percent, net content 21.90 mg, received 07/31/2026, reported 8/5/2026; NEUR2608050352, retatrutide 30mg, lot 260602-02, purity 99.77 percent, net content 31.30 mg, dated August 2026; NEUR2608050353, GLP-TZ 10mg, lot 260517-02, purity 99.94 percent, net content 11.75 mg, dated August 2026. All six match an embedded image already live on the corresponding product page, including NEUR2607310994 for retatrutide 20mg, whose gallery embeds the certificate image with alt text naming its accession and search code, exactly where that page's own text directs a reader to look. A broader prefix query for just 'NEUR' returned roughly 80 additional codes; those were not attributed to this vendor, since the exact-company-name query is the more reliable match and the short prefix plainly catches other clients' codes as well.
Benchmark and prices read from the live product page on 2026-08-26, all USD, no VAT or non-US currency indicated anywhere on the site. Retatrutide is listed under its own name at /product/retatrutide-10mg-research-peptide/, SKU 260217-09 (matching the certificate lot), with a quantity selector on one listing rather than separate kit products: 1 Vial $84, 2 Vials $150, 3 Vials $210, all three variants tied to the same lot and same certificate. Retatrutide 20mg is $120 to $300 across 1 to 3 vials and retatrutide 30mg is $185 to $495. Also recorded, single vials: Tirzepatide (GLP-TZ) 10mg $55, Tesamorelin 10mg $79, Semax 10mg $49, Selank 10mg $45, Ipamorelin 10mg $39, CJC-1295 no DAC 10mg $49 from $55, MOTS-c 10mg $39 from $55, PT-141 10mg $34.99, GLOW blend (GHK-Cu 50mg/TB-500 10mg/BPC-157 10mg) $99 to $220, KLOW blend (GHK-Cu 50mg/TB-500 10mg/BPC-157 10mg/KPV 10mg) $119. No payment method, card network, crypto option or processor name was found on any page fetched today, including the homepage, the retatrutide product page and the Terms of Service; the closest statement is the Terms' generic line that 'orders are accepted once payment is processed and confirmed', with nothing naming how. Shipping is described only in general terms: a sitewide banner states 'Free shipping over $200' and the homepage FAQ states 'Research peptides ship quickly and discreetly from the USA with secure, tracked delivery', with no carrier named, no delivery-time estimate and no explicit statement restricting or permitting shipment outside the United States. Entity: Terms of Service (/terms-of-service/) and the Waiver Agreement (/waiver-agreement/) both name the operator as NEUROPEPTLABS LLC, address 400 N Tampa St STE 1550 PMB 641741, Tampa, Florida 33602-4719 US, a PMB (private mailbox) suite rather than a standalone office address; contact is sales@neuropeptlabs.com, and no telephone number was found on any fetched page. Age gate requires confirming being at least 21 and selecting a purchaser type, private researcher or research institution, before the storefront proceeds.
CAUTIONCautions noted, all from pages fetched today. First, of the 13 products in the catalog, 8 tell a reader their purity is 'Verifiable at freedomdiagnosticstesting.com' with no certificate image anywhere on the page; exercising the lab's own lookup independently corroborated every embedded certificate on the five products that do carry one, including the current retatrutide 20mg document (NEUR2607310994, dated August 2026), which that product's own gallery also embeds, but found nothing at all under the exact company name for those 8, PT-141, MOTS-c, Semax, Selank, KLOW, CJC-1295, Ipamorelin and Tesamorelin, so those eight products' testing claims currently rest on a verification link with no locatable document behind it. Second, the site's own /faqs/ page returned HTTP 500 on two separate fetches today rather than the expected FAQ content; the same broken response still renders a full page body, and that body is generic e-commerce template copy addressing an unrelated business: it discusses 'Standard courier' and 'Express courier' delivery 'applicable only to all Singapore deliveries' on 'Singapore Time (UTC/GMT +8hours)', a 'wrong size or color' return scenario, and a support address of the literal placeholder marketing@company.com, before ending in a raw 'WordPress › Error: There has been a critical error on this website' notice. This is a live, sitemap-indexed page on a USA-facing peptide storefront serving unedited template content for an apparently unrelated retail business, crashing outright rather than resolving to real content. Third, two footer-linked policy pages, Returns & Exchanges and Privacy Policy, redirect (HTTP 301) to /returns-exchanges-2/ and /privacy-policy-2/ respectively, the '-2' suffix pattern WordPress applies when a second page is created under a slug already used by an earlier, presumably deleted page; the live returns page also renders two mojibake glyphs (encoding artifacts) in place of emoji in its own body text. Fourth, payment methods are not disclosed anywhere on the site that was fetched, including the Terms of Service, so a shopper cannot learn what a checkout accepts before reaching it. Fifth, the Terms of Service names the litigation venue as courts in 'Miami-HillsboroughCounty, Florida', a run-together, non-existent county name; the company's own address is in Tampa, which sits in Hillsborough County, while Miami is in a different county roughly 250 miles away, so the clause conflates two unrelated Florida counties into one.
